1 00:00:02,400 --> 00:00:11,119 Speaker 1: Bloomberg Audio Studios, Podcasts, radio news. This is Master's in 2 00:00:11,200 --> 00:00:16,000 Speaker 1: Business with Barry Ridholds on Bloomberg Radio. 3 00:00:16,320 --> 00:00:20,479 Speaker 2: This week on the podcast finally I get Colin Camera 4 00:00:20,680 --> 00:00:26,040 Speaker 2: in the studio to talk about neuroeconomics, behavioral finance, and 5 00:00:26,640 --> 00:00:29,840 Speaker 2: really all the fascinating things he's been doing at Caltech 6 00:00:30,240 --> 00:00:34,480 Speaker 2: for the past. Gee's been there for almost thirty years. 7 00:00:34,560 --> 00:00:37,199 Speaker 2: Is that about right? He's really an interesting guy, not 8 00:00:37,400 --> 00:00:42,240 Speaker 2: just because he has the mathematical and behavioral finance background, 9 00:00:42,640 --> 00:00:47,120 Speaker 2: but because he essentially asked the question, what's going on 10 00:00:47,200 --> 00:00:51,040 Speaker 2: inside our brains when we make decisions? What's happening before 11 00:00:51,040 --> 00:00:55,320 Speaker 2: we even have a degree of awareness of our own decisions. 12 00:00:56,440 --> 00:01:00,600 Speaker 2: I just find what he does fascinating, not just fmyes, 13 00:01:00,640 --> 00:01:05,920 Speaker 2: but eye tracking and eg and galvanomic responses of the skin, 14 00:01:06,000 --> 00:01:08,160 Speaker 2: and just on and on, all these different ways to 15 00:01:08,240 --> 00:01:11,280 Speaker 2: measure what's going on with your hormones, what's going on 16 00:01:11,319 --> 00:01:18,600 Speaker 2: pharmacologically within your body. It's both fascinating and terrifying because 17 00:01:19,200 --> 00:01:23,240 Speaker 2: you come to realize what you think is a decision 18 00:01:23,319 --> 00:01:27,120 Speaker 2: you're making, very often is a decision your brain is 19 00:01:27,160 --> 00:01:30,640 Speaker 2: making with or without you. I found our conversation to 20 00:01:30,640 --> 00:01:34,280 Speaker 2: be absolutely fascinating, and I think you will also with 21 00:01:34,480 --> 00:01:40,120 Speaker 2: no further ado my sit down with Caltech Colin camera. 22 00:01:40,400 --> 00:01:41,800 Speaker 1: Thanks for having me so. 23 00:01:41,880 --> 00:01:44,600 Speaker 2: I've been looking forward to having this conversation with you 24 00:01:45,120 --> 00:01:48,960 Speaker 2: for a long time, not just because of my interest 25 00:01:49,040 --> 00:01:53,760 Speaker 2: in behavioral finance, but because of the space you occupy 26 00:01:54,040 --> 00:01:57,760 Speaker 2: in neuroeconomics. We'll talk a little bit about that in 27 00:01:57,840 --> 00:02:01,360 Speaker 2: a bit, but let's start with your back, which is 28 00:02:01,480 --> 00:02:04,600 Speaker 2: kind of astonishing. You get a bachelor's in quantitative studies 29 00:02:05,000 --> 00:02:09,360 Speaker 2: from john Hopkins at seventeen, and then an MBA in 30 00:02:09,480 --> 00:02:13,399 Speaker 2: finance and a PhD in decision theory from the University 31 00:02:13,440 --> 00:02:16,920 Speaker 2: of Chicago at twenty one. That's a lot of school 32 00:02:17,000 --> 00:02:20,799 Speaker 2: really quickly. What were the career plans? Were you thinking academia? 33 00:02:20,880 --> 00:02:21,959 Speaker 2: Were you thinking finance? 34 00:02:22,600 --> 00:02:25,320 Speaker 1: I was actually kind of not quite sure, So I 35 00:02:25,360 --> 00:02:28,520 Speaker 1: got in. I went to Chicago Grad School for PhD 36 00:02:29,720 --> 00:02:33,480 Speaker 1: in the now Booth School of Business. Because I had 37 00:02:33,680 --> 00:02:36,519 Speaker 1: learned a little bit about finance. I took an independent 38 00:02:36,560 --> 00:02:40,360 Speaker 1: study from Carl Christ who's a famous econometrician at Johns 39 00:02:40,360 --> 00:02:46,080 Speaker 1: Hopkins when Gene Fama's book Foundations of Finance had just 40 00:02:46,160 --> 00:02:48,560 Speaker 1: come out. In fact, I literally worked in the college 41 00:02:48,560 --> 00:02:51,679 Speaker 1: bookstore part time, and I remember unpacking the box to 42 00:02:51,800 --> 00:02:54,320 Speaker 1: have this Fama book, and so I immediately bought one, 43 00:02:54,440 --> 00:02:56,160 Speaker 1: and you know, I was going to do this independent 44 00:02:56,200 --> 00:02:58,400 Speaker 1: study and read through. And by the way, it really 45 00:02:58,480 --> 00:03:01,760 Speaker 1: is some books often called Foundations of Blank. It really 46 00:03:01,800 --> 00:03:04,800 Speaker 1: was Foundations, right, you know, it was the It was 47 00:03:04,800 --> 00:03:07,560 Speaker 1: a summary in the nineteen seventy six, right, very early days. 48 00:03:09,600 --> 00:03:11,920 Speaker 1: And so Carl christ had said, well, you should think 49 00:03:11,919 --> 00:03:16,520 Speaker 1: about Chicago. That's a powerhouse place for finance. And so 50 00:03:16,600 --> 00:03:19,640 Speaker 1: I started studying finance there and passed the prelam which 51 00:03:19,680 --> 00:03:23,280 Speaker 1: is no which is no small feat that's very selective. 52 00:03:23,960 --> 00:03:29,800 Speaker 1: And then I got interested in behavioral science because finance 53 00:03:29,919 --> 00:03:33,520 Speaker 1: was really obsessed with market efficiency and you know, there 54 00:03:33,560 --> 00:03:37,040 Speaker 1: was no behavioral science, behavioral finance in sight at that time. 55 00:03:37,040 --> 00:03:38,840 Speaker 1: But there were other folks at at Chicago. 56 00:03:39,120 --> 00:03:42,840 Speaker 2: Well, if I recall correctly, Dick Taylor was there early 57 00:03:42,920 --> 00:03:47,680 Speaker 2: in the behavioral finance or did he end up there later, Yeah, 58 00:03:47,720 --> 00:03:48,360 Speaker 2: he came later. 59 00:03:48,480 --> 00:03:51,200 Speaker 1: He came later. So when I came in the late seventies, 60 00:03:53,200 --> 00:03:56,960 Speaker 1: a lot of Nobel Prize winners were their Fama, Miller Shoals. 61 00:03:57,520 --> 00:04:00,320 Speaker 1: I think Fisher Black might have just left for MIT 62 00:04:00,720 --> 00:04:05,280 Speaker 1: and when I came, but it was pre Andre Schleifer 63 00:04:05,360 --> 00:04:08,720 Speaker 1: and Ravishni who did a lot of interesting behavioral finance, 64 00:04:08,720 --> 00:04:11,840 Speaker 1: and then Dick Taylor came, I think around nineteen ninety five, 65 00:04:11,920 --> 00:04:12,440 Speaker 1: nineteen to. 66 00:04:12,320 --> 00:04:15,480 Speaker 2: Six, and you were at cal Tech by then, right, 67 00:04:15,640 --> 00:04:16,200 Speaker 2: just correct? 68 00:04:16,200 --> 00:04:18,320 Speaker 1: So yeah, so Dick and I had just passed like 69 00:04:18,360 --> 00:04:21,839 Speaker 1: ships in the night, and I regard that sometimes not 70 00:04:21,920 --> 00:04:23,960 Speaker 1: having just stayed and you know it's been part of 71 00:04:23,960 --> 00:04:25,039 Speaker 1: a new vanguard. 72 00:04:26,320 --> 00:04:29,160 Speaker 2: Well, but you actually are part of a new vanguard 73 00:04:29,160 --> 00:04:31,760 Speaker 2: because the work you do in neuroeconomics, which we're going 74 00:04:31,839 --> 00:04:35,920 Speaker 2: to get into, especially fMRIs and all the other things 75 00:04:35,920 --> 00:04:40,600 Speaker 2: you've done more or less created that space. I mean, 76 00:04:40,600 --> 00:04:45,000 Speaker 2: that's pretty foundational. Behavioral finance has a number of fathers, 77 00:04:45,040 --> 00:04:50,920 Speaker 2: including Dick Taylor and Danny Kahneman. So well, let's circle 78 00:04:51,040 --> 00:04:53,960 Speaker 2: back to the neuroeconomics in a little bit. But I 79 00:04:54,000 --> 00:04:58,160 Speaker 2: want to ask what led you into decision making research? 80 00:04:58,200 --> 00:05:01,440 Speaker 2: How did you find yourself taking the background you had 81 00:05:02,600 --> 00:05:08,479 Speaker 2: in quantitative studies and your PhD and m b a 82 00:05:08,720 --> 00:05:10,200 Speaker 2: and and go into decision making. 83 00:05:11,200 --> 00:05:13,880 Speaker 1: So I some of it was when I was in 84 00:05:13,920 --> 00:05:16,719 Speaker 1: college at Johns Hopkins. I studied physics and math that 85 00:05:16,800 --> 00:05:20,320 Speaker 1: was too abstract, and number theory was just too mind blowing, 86 00:05:20,640 --> 00:05:22,200 Speaker 1: you know for me, like I'm just not going to 87 00:05:22,560 --> 00:05:25,760 Speaker 1: work at that level. And then I studied psychology and 88 00:05:25,800 --> 00:05:28,440 Speaker 1: that seemed like just kind of a list of things 89 00:05:28,480 --> 00:05:31,880 Speaker 1: that happened to people, but there was no unifying wish squishy. 90 00:05:32,520 --> 00:05:35,840 Speaker 1: And then economics, which I really only took a little 91 00:05:35,839 --> 00:05:38,120 Speaker 1: bit of a lot fewer than my peers I later 92 00:05:38,160 --> 00:05:41,040 Speaker 1: competed with in grad school, was kind of in between, 93 00:05:41,080 --> 00:05:42,800 Speaker 1: like the Three Little Bears, you know, there was I 94 00:05:42,839 --> 00:05:45,479 Speaker 1: love that, and there was people right you know, physics 95 00:05:45,480 --> 00:05:47,479 Speaker 1: didn't have people, psychology didn't have math. 96 00:05:47,600 --> 00:05:49,279 Speaker 2: Economics was kind of the right mix. 97 00:05:49,160 --> 00:05:51,920 Speaker 1: Exactly exactly. And I think a lot of a lot 98 00:05:51,920 --> 00:05:54,520 Speaker 1: of social scientists may feel that way, and the people 99 00:05:54,520 --> 00:05:57,000 Speaker 1: who like math lest stay in psychology or go to 100 00:05:57,040 --> 00:06:00,520 Speaker 1: sociology or something where the mathematical structure isn't You found 101 00:06:00,520 --> 00:06:02,000 Speaker 1: the canon and the foundation. 102 00:06:03,440 --> 00:06:06,159 Speaker 2: So what led you into game theory? You end up 103 00:06:06,200 --> 00:06:08,880 Speaker 2: writing a book Behavioral game Theory that was published in 104 00:06:09,160 --> 00:06:13,320 Speaker 2: three How does that relate to economics and decision making 105 00:06:13,600 --> 00:06:14,520 Speaker 2: and investing? 106 00:06:15,440 --> 00:06:18,960 Speaker 1: So in graduate school when I pivoted away from finance, 107 00:06:19,560 --> 00:06:24,599 Speaker 1: there was a couple of psychologist Hilly Einhern and Robin Hogarth, 108 00:06:24,600 --> 00:06:27,320 Speaker 1: who were interested in judgment decision making. They were doing 109 00:06:27,400 --> 00:06:30,120 Speaker 1: things very similar to konomen and diversity. It was sort 110 00:06:30,120 --> 00:06:34,200 Speaker 1: of somewhat mathematical attempts to understand actual human decision making, 111 00:06:34,240 --> 00:06:38,200 Speaker 1: not really stylized like Bay's rule and optimization. You know, 112 00:06:38,200 --> 00:06:40,279 Speaker 1: those are good things to know, but they were interested 113 00:06:40,279 --> 00:06:43,520 Speaker 1: in deviations from those and what that might tell us 114 00:06:43,520 --> 00:06:45,640 Speaker 1: and what the practical value. So that's what I ended 115 00:06:45,680 --> 00:06:48,200 Speaker 1: up doing in grad school. Game theory came a little 116 00:06:48,200 --> 00:06:52,920 Speaker 1: bit later because at Chicago at that time, in the 117 00:06:53,040 --> 00:06:55,719 Speaker 1: late seventies, there was hardly any interest in game theory 118 00:06:55,760 --> 00:06:59,520 Speaker 1: for peculiar reasons. They were, you know, the economic world 119 00:06:59,600 --> 00:07:02,799 Speaker 1: was dominated by price theory supplying demand like Gary Becker, 120 00:07:02,839 --> 00:07:04,640 Speaker 1: you know, there was a lot going on. Game theory 121 00:07:04,720 --> 00:07:07,840 Speaker 1: just was not flourishing there. But my first job was 122 00:07:07,839 --> 00:07:11,440 Speaker 1: as an assistant professor in Northwestern and that happened to be, 123 00:07:12,280 --> 00:07:16,600 Speaker 1: through just historical coincidence, a hotbed of great game theory. 124 00:07:16,640 --> 00:07:19,960 Speaker 1: Paul Milgram was there, Banked Holmestrom was there, Robert Weber, 125 00:07:20,000 --> 00:07:25,000 Speaker 1: who worked on lots of things on auction theory, Dave Barren, 126 00:07:25,000 --> 00:07:28,120 Speaker 1: who was interested in political economy, and you know, political 127 00:07:28,160 --> 00:07:32,680 Speaker 1: systems as games. So Milgrim and Holstrom went on to 128 00:07:32,720 --> 00:07:35,760 Speaker 1: win Nobel prizes and went to other places. So it 129 00:07:35,800 --> 00:07:39,440 Speaker 1: was sort of this incubator place that then, you know, 130 00:07:40,080 --> 00:07:44,280 Speaker 1: like a incubator like Hewlett Packard and things like that, 131 00:07:44,320 --> 00:07:46,800 Speaker 1: where people then went off to do other stuff. And 132 00:07:46,880 --> 00:07:49,400 Speaker 1: so I basically learned game theory in my first job 133 00:07:49,440 --> 00:07:53,720 Speaker 1: as AISTM professor, and that game theory is similar to 134 00:07:54,120 --> 00:07:57,800 Speaker 1: behavor economics. The standard theory that everyone teaches in every 135 00:07:57,800 --> 00:08:03,200 Speaker 1: introductory course is people arend and make the best choices 136 00:08:03,240 --> 00:08:05,920 Speaker 1: given what they think others will do, and they're correct 137 00:08:06,040 --> 00:08:08,600 Speaker 1: guessing about what others do. Like a bunch of people 138 00:08:08,600 --> 00:08:10,760 Speaker 1: who played poker with each other, you know, every Friday 139 00:08:10,840 --> 00:08:13,640 Speaker 1: night for decades, they kind of know what the tells are. 140 00:08:14,520 --> 00:08:17,280 Speaker 1: But we were interested in what happens before you get 141 00:08:17,280 --> 00:08:19,760 Speaker 1: to this kind of what's called Nash equilibrium, you know, 142 00:08:19,760 --> 00:08:21,880 Speaker 1: where everyone is guessed correctly what everyone's going to do. 143 00:08:23,080 --> 00:08:25,000 Speaker 1: And so to me, there was a huge room for 144 00:08:26,200 --> 00:08:29,760 Speaker 1: understanding the psychology of strategic thinking in game theory. 145 00:08:29,880 --> 00:08:33,880 Speaker 2: So that's really interesting to me. I always found the 146 00:08:33,920 --> 00:08:40,400 Speaker 2: traditional economic homo economists of humans as rational calculating profit 147 00:08:40,520 --> 00:08:46,480 Speaker 2: maximizing actors is just complete contradiction of real life experience. 148 00:08:47,240 --> 00:08:50,559 Speaker 2: How did you go from your initial interest in behavioral 149 00:08:50,600 --> 00:08:57,400 Speaker 2: finance into neuroeconomics, where you're looking at the biological underpinnings 150 00:08:57,559 --> 00:08:59,960 Speaker 2: of what happens as people make decisions. 151 00:09:00,360 --> 00:09:02,439 Speaker 1: Yeah, So the neuroeconomics to me was sort of a 152 00:09:02,520 --> 00:09:06,000 Speaker 1: natural extension of behavior economics, which was We're going to 153 00:09:06,360 --> 00:09:09,200 Speaker 1: grab from any interesting data and different ways of thinking 154 00:09:09,200 --> 00:09:12,600 Speaker 1: about humans outside of standard economics and kind of pull 155 00:09:12,600 --> 00:09:14,640 Speaker 1: it in and try to, you know, generate a kind 156 00:09:14,640 --> 00:09:16,959 Speaker 1: of hybrid. It was almost like an import export business. 157 00:09:16,960 --> 00:09:19,520 Speaker 1: And I'm going to import some psychology or dicktale or 158 00:09:19,559 --> 00:09:22,240 Speaker 1: imported from konomon and what is this going to tell 159 00:09:22,280 --> 00:09:25,320 Speaker 1: us about fairness and reference points and loss aversion what 160 00:09:25,440 --> 00:09:27,680 Speaker 1: have you? And neur economics seem to me like just 161 00:09:27,720 --> 00:09:30,720 Speaker 1: another thing to do. Part of it is my personality 162 00:09:30,760 --> 00:09:33,840 Speaker 1: is kind of like intellectual entrepreneurship. So I liked you know, 163 00:09:33,880 --> 00:09:36,160 Speaker 1: doing different things. You know, over the years, I've worked 164 00:09:36,200 --> 00:09:38,800 Speaker 1: on lots of different methods and with different groups of people, 165 00:09:38,840 --> 00:09:41,720 Speaker 1: and neureconomics was just a chance to do something even 166 00:09:41,760 --> 00:09:43,559 Speaker 1: more dramatic. 167 00:09:43,440 --> 00:09:48,160 Speaker 2: And tell us about your patent on active learning decision engines. 168 00:09:48,600 --> 00:09:49,960 Speaker 2: What on earth is that? 169 00:09:50,200 --> 00:09:53,280 Speaker 1: So active learning is the commuter scientist term is sometimes 170 00:09:53,280 --> 00:09:57,120 Speaker 1: called dynamic adaptive learning. For basically, like if I was 171 00:09:57,160 --> 00:10:00,440 Speaker 1: going to try to figure out how much you like risk, 172 00:10:00,600 --> 00:10:03,160 Speaker 1: like you were a client, and if a financial advisor 173 00:10:03,240 --> 00:10:06,080 Speaker 1: is asking you know, I might start by saying, well, 174 00:10:06,440 --> 00:10:09,200 Speaker 1: here's a portfolio. Is this too risky or not risky enough? 175 00:10:09,720 --> 00:10:12,040 Speaker 1: And if you say, nah, that's not risky enough, you know, 176 00:10:12,080 --> 00:10:14,960 Speaker 1: I'd rather go for more, and then I would give 177 00:10:15,000 --> 00:10:16,680 Speaker 1: you a better one that's a little has a little 178 00:10:16,720 --> 00:10:19,960 Speaker 1: more risk in it. And in chemistry it's called titration. 179 00:10:20,320 --> 00:10:22,760 Speaker 1: You know, you kind of change the mixture of the chemicals. 180 00:10:23,280 --> 00:10:25,840 Speaker 1: And so for each person, you're asking them a dynamic, 181 00:10:26,760 --> 00:10:29,360 Speaker 1: customized set of questions to get to the best answer 182 00:10:29,400 --> 00:10:33,200 Speaker 1: as quickly as possible, and that's called active learning. So 183 00:10:33,360 --> 00:10:36,560 Speaker 1: one of my colleagues at Caltech at that time, Andreas Krauss, 184 00:10:37,160 --> 00:10:39,920 Speaker 1: was studying he was a Gonna Better scientist. So they're 185 00:10:39,960 --> 00:10:43,160 Speaker 1: always on the frontier of how to get the truth 186 00:10:43,480 --> 00:10:47,600 Speaker 1: faster and subject to computational constraints, like you know, because 187 00:10:47,600 --> 00:10:50,360 Speaker 1: sometimes it's not just a question. I'm getting there, but 188 00:10:50,480 --> 00:10:52,200 Speaker 1: can you do it in real time so you don't 189 00:10:52,240 --> 00:10:55,040 Speaker 1: have to wait half an hour, you know, to ask 190 00:10:55,080 --> 00:10:59,320 Speaker 1: the next highly unformative question. And so the patent was 191 00:10:59,360 --> 00:11:02,800 Speaker 1: just a a method that Andreas and another guy who 192 00:11:02,920 --> 00:11:05,480 Speaker 1: now works like Google, I believe Daniel Goldman and me 193 00:11:05,800 --> 00:11:09,520 Speaker 1: had worked on to apply this in a particular way. 194 00:11:09,600 --> 00:11:11,480 Speaker 1: And so it was basically a software pattern. There was 195 00:11:11,480 --> 00:11:13,080 Speaker 1: an Advazon pattern on an algorithm. 196 00:11:13,240 --> 00:11:17,440 Speaker 2: So you're asking people questions, how do you know they're 197 00:11:17,480 --> 00:11:21,600 Speaker 2: giving you honest answers? And I asked that question for 198 00:11:21,720 --> 00:11:24,680 Speaker 2: very specific reasons that will be evident in a moment. 199 00:11:25,080 --> 00:11:27,679 Speaker 2: How do you know the answers are legitimate? 200 00:11:27,760 --> 00:11:31,800 Speaker 1: Okay, So in experiment economics, one of the main rules, 201 00:11:31,840 --> 00:11:35,120 Speaker 1: like a commandment, is we almost always pay people unless 202 00:11:35,160 --> 00:11:37,400 Speaker 1: we can't, like with children sometimes or what have you. 203 00:11:38,040 --> 00:11:40,360 Speaker 1: We almost always pay people money or something we know 204 00:11:40,400 --> 00:11:43,440 Speaker 1: they value based on the decisions they made. So when 205 00:11:43,480 --> 00:11:46,640 Speaker 1: we do these kind of risk assessments, again not with clients, 206 00:11:46,640 --> 00:11:48,760 Speaker 1: but say in a simple experiment for modest amounts of 207 00:11:48,760 --> 00:11:51,280 Speaker 1: money twenty bucks, fifty bucks, what we'll do is we 208 00:11:51,360 --> 00:11:52,719 Speaker 1: say at the end, we're going to pick one of 209 00:11:52,760 --> 00:11:54,280 Speaker 1: the things you said you wanted, and we're going to 210 00:11:54,320 --> 00:11:57,840 Speaker 1: actually play that for money. And if you if you 211 00:11:57,840 --> 00:11:59,280 Speaker 1: don't tell us what you really wanted, you're gonna get 212 00:11:59,320 --> 00:11:59,880 Speaker 1: stuck with something. 213 00:12:00,600 --> 00:12:04,280 Speaker 2: So you're creating an incentive for them to be somewhat honest. 214 00:12:04,520 --> 00:12:04,800 Speaker 1: Correct. 215 00:12:05,040 --> 00:12:08,160 Speaker 2: The reason I ask we're recording this about two weeks 216 00:12:08,200 --> 00:12:12,000 Speaker 2: before the twenty twenty four presidential election. I wrote something 217 00:12:12,000 --> 00:12:16,000 Speaker 2: a month ago about why polling errors are really a 218 00:12:16,040 --> 00:12:20,080 Speaker 2: behavioral problem because when you ask people who you're going 219 00:12:20,160 --> 00:12:22,640 Speaker 2: to vote for, what you're really asking is not just 220 00:12:22,720 --> 00:12:25,560 Speaker 2: their preference, but hey, you're gonna get your lazy butt 221 00:12:26,000 --> 00:12:27,920 Speaker 2: off the couch and go to the library and vote. 222 00:12:28,280 --> 00:12:31,520 Speaker 2: And I assumed, hey, there's an era of five, six 223 00:12:31,640 --> 00:12:34,360 Speaker 2: seven percent built into that, and that's why polls are 224 00:12:34,360 --> 00:12:39,679 Speaker 2: so bad. Researching your work about hypothetical bias, I was 225 00:12:39,800 --> 00:12:43,160 Speaker 2: shocked the data that you came is when you ask 226 00:12:43,200 --> 00:12:45,600 Speaker 2: people if they're going to vote, about seventy percent say 227 00:12:45,640 --> 00:12:49,360 Speaker 2: they will, In reality, just forty five percent of them do. 228 00:12:49,840 --> 00:12:54,000 Speaker 2: That's a massive error of twenty five percent. What value 229 00:12:54,040 --> 00:12:56,520 Speaker 2: is there in polls when people have no idea what 230 00:12:56,559 --> 00:12:57,360 Speaker 2: they're really going to do? 231 00:12:57,960 --> 00:13:00,360 Speaker 1: Yeah, So I mean I think the best post are 232 00:13:01,280 --> 00:13:03,480 Speaker 1: know that, and so they try to phrase the question 233 00:13:03,640 --> 00:13:06,560 Speaker 1: or gather some other data. But this is often called 234 00:13:06,559 --> 00:13:09,760 Speaker 1: acquiescence or yes bias. Right, so you say, people, are 235 00:13:09,800 --> 00:13:11,840 Speaker 1: you planning to vote? Oh, yeah, I'm planning to vote, Well, 236 00:13:11,880 --> 00:13:13,320 Speaker 1: you're going to Are you going to not vote because 237 00:13:13,320 --> 00:13:14,840 Speaker 1: it's too Yeah, I may not vote. 238 00:13:14,880 --> 00:13:16,880 Speaker 2: What happens if it rains, what happens if you're busy. 239 00:13:17,520 --> 00:13:19,040 Speaker 1: So you can often get numbers in it up to 240 00:13:19,040 --> 00:13:21,199 Speaker 1: more than one hundred percent. Are you having to vote? No, 241 00:13:21,360 --> 00:13:24,240 Speaker 1: you have seventy percent. Yeah, I probably won't vote fifty 242 00:13:24,240 --> 00:13:26,280 Speaker 1: five percent. That's one hundred and twenty five percent current. 243 00:13:26,440 --> 00:13:29,880 Speaker 1: The math doesn't math, and you see it. Particularly. One 244 00:13:29,880 --> 00:13:32,640 Speaker 1: of the things we study was product purchases. So when 245 00:13:32,640 --> 00:13:34,599 Speaker 1: you show people new products and say, you know, you 246 00:13:34,600 --> 00:13:37,000 Speaker 1: think you'd be interested in this, you get way too 247 00:13:37,040 --> 00:13:40,240 Speaker 1: many yes's. And that's one recent new products fail. It 248 00:13:40,320 --> 00:13:43,559 Speaker 1: is because somebody who's the product champion inside the firm, 249 00:13:43,720 --> 00:13:45,960 Speaker 1: like in a consumer products company, looks at this polling 250 00:13:46,040 --> 00:13:48,440 Speaker 1: date and says, see, see you know, give me money 251 00:13:48,480 --> 00:13:51,960 Speaker 1: to roll this out in a test market. So what 252 00:13:52,040 --> 00:13:53,680 Speaker 1: one of the things we have done is to try 253 00:13:53,720 --> 00:13:56,200 Speaker 1: to see if we didn't, we'd wro'te a few papers 254 00:13:56,240 --> 00:13:58,480 Speaker 1: on this, but I don't feel like we exactly crack 255 00:13:58,559 --> 00:14:01,920 Speaker 1: the nut was to see if a combination of what 256 00:14:02,000 --> 00:14:04,600 Speaker 1: people look at if you measure where their eyes are looking, 257 00:14:05,320 --> 00:14:08,080 Speaker 1: like how often they look back and forth between a 258 00:14:08,120 --> 00:14:12,160 Speaker 1: price and a product, and maybe brain signals can help 259 00:14:12,240 --> 00:14:14,720 Speaker 1: us predict when they say, yeah, I'm going to vote, 260 00:14:14,760 --> 00:14:15,800 Speaker 1: are they really going to vote or not? 261 00:14:16,160 --> 00:14:20,800 Speaker 2: And neuroeconomics, as as I've learned about it through you 262 00:14:21,480 --> 00:14:24,080 Speaker 2: is you're putting people in a functional MRI machine. You're 263 00:14:24,120 --> 00:14:27,360 Speaker 2: asking them a series of questions, and you're identifying what 264 00:14:27,560 --> 00:14:29,800 Speaker 2: parts of the brain are actually lighting up. 265 00:14:29,920 --> 00:14:32,480 Speaker 1: Correct exactly so that so and and by the way, 266 00:14:32,480 --> 00:14:37,480 Speaker 1: ephraimri is glamorous and fantastic, but there's lots of other 267 00:14:37,480 --> 00:14:39,640 Speaker 1: methode that they are used as well. You know, it's 268 00:14:39,720 --> 00:14:42,760 Speaker 1: unnatural because people are in this tube. It's very loud. 269 00:14:43,120 --> 00:14:44,840 Speaker 1: You know, if you want to study a phobic, if 270 00:14:44,840 --> 00:14:46,880 Speaker 1: you want to study close to probi, you cannot, you know, 271 00:14:46,920 --> 00:14:50,240 Speaker 1: because the closer roobics won't go in there. But it 272 00:14:50,280 --> 00:14:52,240 Speaker 1: does give you a picture of the whole brain. And 273 00:14:52,280 --> 00:14:55,560 Speaker 1: in the in the case of the we need some 274 00:14:55,600 --> 00:14:58,320 Speaker 1: experiments where we show people to consumer good and in 275 00:14:58,360 --> 00:15:00,920 Speaker 1: one condition. The first part of the experiment we say, 276 00:15:01,040 --> 00:15:02,880 Speaker 1: you don't have to actually buy this, but just tell us, 277 00:15:02,920 --> 00:15:04,640 Speaker 1: you know if it was on sale for this price, 278 00:15:04,800 --> 00:15:08,560 Speaker 1: like yes, no, strong, yes, weak yess. So we get 279 00:15:08,560 --> 00:15:11,560 Speaker 1: a four point scale and then we surprise them and say, 280 00:15:11,760 --> 00:15:13,640 Speaker 1: now we're going to show you some different products and 281 00:15:13,720 --> 00:15:15,840 Speaker 1: these are going to actually buy. So if you say 282 00:15:15,920 --> 00:15:18,560 Speaker 1: yes and we choose that one out of this. 283 00:15:18,760 --> 00:15:19,720 Speaker 2: Bin, you get it. 284 00:15:19,960 --> 00:15:21,960 Speaker 1: You have you have to buy it. Well, we give 285 00:15:22,000 --> 00:15:24,040 Speaker 1: you some money and we're going to take the price 286 00:15:24,080 --> 00:15:27,080 Speaker 1: out and give you the residual money and the product, 287 00:15:27,120 --> 00:15:29,160 Speaker 1: and you're going to leave here with this product or 288 00:15:29,240 --> 00:15:30,920 Speaker 1: I think some of them we have we mail it 289 00:15:30,960 --> 00:15:33,600 Speaker 1: to them at Amazon is something we actually had products 290 00:15:33,640 --> 00:15:37,680 Speaker 1: there in a box. And so the question is what's 291 00:15:37,720 --> 00:15:40,240 Speaker 1: going on in the brain when they're seriously thinking about 292 00:15:40,280 --> 00:15:44,240 Speaker 1: buying something for real versus hypothetical, which is like a survey, right, 293 00:15:45,400 --> 00:15:47,520 Speaker 1: And what we found was the tricky part is to 294 00:15:48,280 --> 00:15:53,080 Speaker 1: predict when people say yes, hypothetical, but the brain says no, 295 00:15:53,880 --> 00:15:55,360 Speaker 1: you know, can you can you see a brain? 296 00:15:55,600 --> 00:15:56,520 Speaker 2: Can you identify that? 297 00:15:56,920 --> 00:15:58,840 Speaker 1: Uh? Modestly well? 298 00:15:59,160 --> 00:15:59,280 Speaker 2: Right? 299 00:15:59,520 --> 00:16:02,920 Speaker 1: And it turns out the most. There's two interesting markers. 300 00:16:02,960 --> 00:16:05,960 Speaker 1: One is there's a very old area in the brain, 301 00:16:06,040 --> 00:16:10,440 Speaker 1: old you know, evolutionary yes, called the mid brain, which 302 00:16:10,480 --> 00:16:14,280 Speaker 1: is actually where all of the dopamina drid neurons live 303 00:16:14,600 --> 00:16:18,240 Speaker 1: and then and then connect to middle areas of the 304 00:16:18,240 --> 00:16:21,440 Speaker 1: brain called basoganglia that are kind of computing reward and value. 305 00:16:21,480 --> 00:16:24,200 Speaker 1: And then frontal cortex, which is really putting together the 306 00:16:24,240 --> 00:16:27,560 Speaker 1: modern the modern exactly like it's like a thinking cap 307 00:16:27,600 --> 00:16:30,960 Speaker 1: on top of the monkey brain. And in the mid 308 00:16:31,000 --> 00:16:36,600 Speaker 1: brain there's a stronger signal when they say yes and 309 00:16:36,640 --> 00:16:40,720 Speaker 1: they actually do do yes hypothetical and it's a yes reel. 310 00:16:41,080 --> 00:16:43,800 Speaker 1: There's a stronger signal than when they say yes hypothetical 311 00:16:44,080 --> 00:16:47,080 Speaker 1: no real. So it's almost like way upstream in the 312 00:16:47,080 --> 00:16:52,680 Speaker 1: brain if if if in that region they say yes, 313 00:16:52,720 --> 00:16:55,640 Speaker 1: I'm gonna buy it hypothetically, there's enough activity they're gonna 314 00:16:55,640 --> 00:16:55,920 Speaker 1: buy it. 315 00:16:56,400 --> 00:16:59,880 Speaker 2: So my general sense of this, and I'm curious as 316 00:17:00,080 --> 00:17:03,240 Speaker 2: to how you what the reality is, my sense of 317 00:17:03,280 --> 00:17:06,840 Speaker 2: it is, on the one hand, people are social animals 318 00:17:06,840 --> 00:17:09,919 Speaker 2: and they want to be agreeable and say yes to people. 319 00:17:10,680 --> 00:17:13,040 Speaker 2: On the other hand, we really don't know what the 320 00:17:13,080 --> 00:17:16,359 Speaker 2: hell we want, especially if you're talking about something six 321 00:17:16,440 --> 00:17:19,760 Speaker 2: months from now. I guess the tricky part is how 322 00:17:19,760 --> 00:17:22,680 Speaker 2: do you get people in MRI machines when you have 323 00:17:22,720 --> 00:17:24,639 Speaker 2: a question for them. We can't even get people to 324 00:17:24,640 --> 00:17:28,240 Speaker 2: pick up their phone to answer polls. How difficult is 325 00:17:28,280 --> 00:17:31,399 Speaker 2: it to get subjects to go through this process? Or 326 00:17:31,400 --> 00:17:34,840 Speaker 2: are these all mostly undergraduates and you know their lab rats? 327 00:17:34,880 --> 00:17:35,680 Speaker 2: You can do whatever you want. 328 00:17:35,760 --> 00:17:39,600 Speaker 1: Some of them are undergraduates, although in Caltech they're very 329 00:17:39,680 --> 00:17:43,640 Speaker 1: unusual human beings because they're actually useful. They're very useful 330 00:17:44,119 --> 00:17:47,120 Speaker 1: labrats who pay for economics because the media and matthe 331 00:17:47,240 --> 00:17:51,639 Speaker 1: Is et Is eight hundred, they're the most mathematically skilled except. 332 00:17:51,400 --> 00:17:52,879 Speaker 2: For that's a perfect score, isn't it? 333 00:17:52,920 --> 00:17:55,480 Speaker 1: Like exactly, that's the perfect score, like Harvey mud Mit. 334 00:17:55,640 --> 00:17:58,800 Speaker 1: There are other places that have, you know, similarly hyper 335 00:17:58,800 --> 00:18:02,479 Speaker 1: analytical kids. So if like if they can't do something 336 00:18:02,600 --> 00:18:07,359 Speaker 1: like a computation easily, nobody can. So it's very useful 337 00:18:07,520 --> 00:18:10,720 Speaker 1: establishing like bounds on rationality. You know that people. We 338 00:18:10,760 --> 00:18:13,320 Speaker 1: often get critiques like well, you wouldn't get bubbles if 339 00:18:13,359 --> 00:18:16,240 Speaker 1: people were smart enough, Like, well, we have the smartest 340 00:18:16,240 --> 00:18:17,320 Speaker 1: people and you get bubbles. 341 00:18:18,520 --> 00:18:20,879 Speaker 2: It's got less to do with the frontal cortex and 342 00:18:20,920 --> 00:18:24,199 Speaker 2: intelligence and everything with that, the limbic system and the 343 00:18:24,240 --> 00:18:25,000 Speaker 2: lizard brain back. 344 00:18:25,080 --> 00:18:27,120 Speaker 1: Yes, exactly, so they have they have all the things 345 00:18:27,200 --> 00:18:29,000 Speaker 1: in the brain they have, they have other skills that 346 00:18:29,040 --> 00:18:33,479 Speaker 1: are cordically expressed. But so in a lot of these 347 00:18:33,600 --> 00:18:36,440 Speaker 1: MRI studies we also use. We work pretty hard actually 348 00:18:36,440 --> 00:18:39,960 Speaker 1: to get regular folks from the community who and who 349 00:18:40,200 --> 00:18:42,800 Speaker 1: you know are different ages. You know, we we don't 350 00:18:42,800 --> 00:18:45,359 Speaker 1: really have a representative sample, although you could, you could 351 00:18:45,359 --> 00:18:49,200 Speaker 1: try to get pretty close in southern California, and then 352 00:18:49,240 --> 00:18:51,399 Speaker 1: we we we almost always never do a study this 353 00:18:51,680 --> 00:18:54,600 Speaker 1: just take outing undergrads because we worry about the robustness 354 00:18:54,600 --> 00:18:57,080 Speaker 1: across right, It is true in the case of something 355 00:18:57,200 --> 00:18:59,960 Speaker 1: like trying to get brain signals to break when people 356 00:19:00,000 --> 00:19:03,560 Speaker 1: will actually buy products. The other type of study we've 357 00:19:03,640 --> 00:19:05,719 Speaker 1: used to involves eye tracking and things like that, and 358 00:19:05,760 --> 00:19:09,480 Speaker 1: it turns out that when when you ask people hypothetical questions, 359 00:19:09,520 --> 00:19:11,119 Speaker 1: would you buy that? You don't really have to buy this, 360 00:19:11,240 --> 00:19:13,320 Speaker 1: but would you, they just don't look at the price 361 00:19:13,359 --> 00:19:16,960 Speaker 1: that much, and when they're really shopping, they really look 362 00:19:17,000 --> 00:19:19,840 Speaker 1: at the price. So one way to tell whether people 363 00:19:19,880 --> 00:19:23,720 Speaker 1: are being serious in expressing a genuine what I'm going 364 00:19:23,720 --> 00:19:26,320 Speaker 1: to really do, it is just something like how much 365 00:19:26,359 --> 00:19:28,080 Speaker 1: time they spend looking at the price and looking back 366 00:19:28,119 --> 00:19:31,520 Speaker 1: and forth. And there may be other like if if 367 00:19:32,840 --> 00:19:35,280 Speaker 1: if it was consumer products company was trying to use 368 00:19:35,560 --> 00:19:38,600 Speaker 1: FROMRI or other methods. There are others that are much 369 00:19:38,640 --> 00:19:41,520 Speaker 1: more portable, like EEG, and you can get a pair 370 00:19:41,520 --> 00:19:43,919 Speaker 1: of glasses you walk around and it, you know, it 371 00:19:44,000 --> 00:19:46,159 Speaker 1: records where your eyes looking. So there are there are 372 00:19:46,160 --> 00:19:49,119 Speaker 1: things you can do outside of the confines of a 373 00:19:49,119 --> 00:19:52,320 Speaker 1: campus lab. I think we would just look for things 374 00:19:52,359 --> 00:19:56,800 Speaker 1: that are that are easy, easily seen biomarkers of this 375 00:19:56,960 --> 00:19:59,400 Speaker 1: mid brain activity of f MRI, because we're never gonna 376 00:19:59,400 --> 00:20:01,320 Speaker 1: be able to do that, you know, at scale in 377 00:20:01,400 --> 00:20:03,000 Speaker 1: a shopping mall or something. 378 00:20:03,160 --> 00:20:04,919 Speaker 2: So let's go through each of these. We know what 379 00:20:05,119 --> 00:20:10,280 Speaker 2: fMRI is, right, you're in an MRI machine. EEG and SCR. 380 00:20:10,400 --> 00:20:11,359 Speaker 2: Tell us what those do. 381 00:20:11,680 --> 00:20:15,280 Speaker 1: So eg's electro and cephalography and it's basically all the 382 00:20:15,320 --> 00:20:19,760 Speaker 1: little things on your electrodes. If your ball like me, 383 00:20:19,880 --> 00:20:23,359 Speaker 1: that's good for seasons. You know, if you're a supermodel 384 00:20:23,359 --> 00:20:27,400 Speaker 1: with big puffy Texas beauty pageant hair, then no good, 385 00:20:27,520 --> 00:20:27,880 Speaker 1: no good. 386 00:20:28,520 --> 00:20:31,560 Speaker 2: So you're measuring electrical activity in the brain, and you 387 00:20:31,600 --> 00:20:35,240 Speaker 2: could really specify where it is by you know, just 388 00:20:35,640 --> 00:20:39,240 Speaker 2: triangulating with all the different leads that you have spect. 389 00:20:39,200 --> 00:20:42,240 Speaker 1: Exactly so the you know, you can put sixteen to 390 00:20:42,280 --> 00:20:45,280 Speaker 1: one hundred and twenty eight different electrodes. The signals are 391 00:20:45,440 --> 00:20:48,840 Speaker 1: very weak, but the advantage of EG is it's really fast. 392 00:20:49,280 --> 00:20:51,399 Speaker 1: So if you want to study something like thinking fast 393 00:20:51,440 --> 00:20:53,359 Speaker 1: and slow, you know, like if I show you a 394 00:20:53,359 --> 00:20:55,600 Speaker 1: picture of a person, you have a snap reaction that 395 00:20:55,680 --> 00:20:57,800 Speaker 1: they're scary or they're someone you want to vote for, 396 00:20:58,359 --> 00:21:01,359 Speaker 1: then FRI is too slow because it measures these blood 397 00:21:01,359 --> 00:21:03,480 Speaker 1: flow signals that take like one or two seconds to 398 00:21:03,520 --> 00:21:03,920 Speaker 1: show up. 399 00:21:04,240 --> 00:21:08,400 Speaker 2: But like one, one or two seconds is too slow for. 400 00:21:08,920 --> 00:21:11,959 Speaker 1: You know, a lot is going on in the in 401 00:21:12,320 --> 00:21:14,040 Speaker 1: the first two seconds where people are thinking out of 402 00:21:14,040 --> 00:21:18,320 Speaker 1: a decision that's really interesting necessarily you know, which mortgage 403 00:21:18,359 --> 00:21:20,240 Speaker 1: to finance, their refinance their house in. 404 00:21:20,320 --> 00:21:24,560 Speaker 2: Or literally system one thinking fast is exactly. 405 00:21:24,280 --> 00:21:27,480 Speaker 1: So it's the term psychologist. Social psychology use is also 406 00:21:27,480 --> 00:21:30,440 Speaker 1: called thin slicing, which is that and the thin slices 407 00:21:30,520 --> 00:21:34,520 Speaker 1: on the order of meaning a very aggregate, somewhat confident 408 00:21:34,600 --> 00:21:38,440 Speaker 1: judgment is made within you know, ten seconds, thirty seconds, 409 00:21:38,680 --> 00:21:42,520 Speaker 1: there's a big literature, and we're interviewing about this that, 410 00:21:42,960 --> 00:21:45,600 Speaker 1: you know, face to base interviewing. Unless you're really trained 411 00:21:45,640 --> 00:21:49,280 Speaker 1: to have a comparable interview for different people, you know, 412 00:21:49,359 --> 00:21:51,800 Speaker 1: the first couple of minutes of the interview, you're kind 413 00:21:51,800 --> 00:21:54,200 Speaker 1: of making up your mind. At least a lot of 414 00:21:54,200 --> 00:21:55,200 Speaker 1: studies indicate that. 415 00:21:55,280 --> 00:21:58,080 Speaker 2: And SCR is what so SCR. 416 00:21:57,800 --> 00:22:02,199 Speaker 1: Skin conducted response, also called galvanic skin response. And so 417 00:22:02,280 --> 00:22:06,960 Speaker 1: basically it turns out when people are aroused in any 418 00:22:07,080 --> 00:22:08,960 Speaker 1: any direction, it doesn't tell you good or bab, but 419 00:22:09,000 --> 00:22:12,000 Speaker 1: it just tells you arousal. You have this detectable increase 420 00:22:12,119 --> 00:22:14,960 Speaker 1: in sweating you can measure in the fingers. 421 00:22:15,720 --> 00:22:19,440 Speaker 2: So and in all of these things, you're actually taking measurements, 422 00:22:19,560 --> 00:22:23,479 Speaker 2: not asking people things. And one of the quotes that 423 00:22:23,520 --> 00:22:26,960 Speaker 2: caught my attention. Since most of our brain activity goes 424 00:22:27,000 --> 00:22:31,479 Speaker 2: on without our awareness subconsciously, we cannot solely rely on 425 00:22:31,640 --> 00:22:37,440 Speaker 2: individual's accounts when analyzing their behavior. How important is the 426 00:22:37,440 --> 00:22:41,800 Speaker 2: concept of the subconscious to neuroeconomics. 427 00:22:41,480 --> 00:22:44,120 Speaker 1: It's pretty important. So the saying we use is sometimes 428 00:22:44,160 --> 00:22:46,119 Speaker 1: you want to ask the brain rather than ask the person, 429 00:22:46,240 --> 00:22:50,240 Speaker 1: uh huh. And there's some there's some extreme ways in 430 00:22:50,240 --> 00:22:52,840 Speaker 1: which that works. For example, if I show a face 431 00:22:52,880 --> 00:22:56,800 Speaker 1: of somebody who's expressing fear but only for thirty milliseconds, 432 00:22:56,800 --> 00:23:00,239 Speaker 1: which is one movie frame right right, and then a 433 00:23:00,280 --> 00:23:03,360 Speaker 1: mask when you're meeting another face right on top that's neutral, 434 00:23:04,280 --> 00:23:07,080 Speaker 1: or in another condition, I show a happy face, very enthusiastic, 435 00:23:07,160 --> 00:23:09,720 Speaker 1: and then neutral mask. If you ask people did you 436 00:23:09,760 --> 00:23:13,520 Speaker 1: see a happi or fearful face, they say, like, I 437 00:23:13,560 --> 00:23:15,560 Speaker 1: have no idea, I didn't see I didn't see either one. 438 00:23:15,960 --> 00:23:18,159 Speaker 1: But if you look at amigdal activity, which is a 439 00:23:18,200 --> 00:23:22,879 Speaker 1: region that's known to be rapidly detecting potential threats and 440 00:23:23,200 --> 00:23:27,240 Speaker 1: including fear, the amignal activity will respond to fear, not 441 00:23:28,520 --> 00:23:31,760 Speaker 1: in thirty milliseconds, not not happiness in the same way. 442 00:23:31,880 --> 00:23:35,160 Speaker 1: So the brain knows, it's just that it doesn't get 443 00:23:35,160 --> 00:23:40,040 Speaker 1: to the like the publicists desk, you know, good consciousness. 444 00:23:40,080 --> 00:23:41,800 Speaker 2: So I'm so glad you said it that way. So 445 00:23:41,880 --> 00:23:44,840 Speaker 2: don't ask the person, ask the brain. How do you 446 00:23:44,960 --> 00:23:48,159 Speaker 2: think of the different parts of the brain. So obviously 447 00:23:48,680 --> 00:23:51,720 Speaker 2: the amygdala and any of the is it fair to 448 00:23:51,720 --> 00:23:55,760 Speaker 2: say that's part of the limbic system. Yes, So when 449 00:23:55,760 --> 00:23:59,600 Speaker 2: you're talking about the publicist. What portion of the brain 450 00:23:59,720 --> 00:24:02,080 Speaker 2: we just discussing, Well. 451 00:24:01,880 --> 00:24:05,359 Speaker 1: In terms of sheer territory, it's probably not very much. 452 00:24:07,520 --> 00:24:11,480 Speaker 1: Four brain, hind brain were prefrontal cortex would be. And 453 00:24:13,760 --> 00:24:16,600 Speaker 1: there's a lot of sensory procection that's going on, you know, 454 00:24:16,880 --> 00:24:19,960 Speaker 1: pre conscious or like before we could say, you know, 455 00:24:21,040 --> 00:24:23,920 Speaker 1: motion to something or use words to explain what's going on. 456 00:24:24,480 --> 00:24:27,600 Speaker 1: I think it's it's it's genuinely hard to pin down 457 00:24:27,600 --> 00:24:29,919 Speaker 1: a number. Like you know, if I read, for example, 458 00:24:29,920 --> 00:24:32,960 Speaker 1: it's ninety percent subconscious and ten percent conscious, I don't 459 00:24:32,960 --> 00:24:37,000 Speaker 1: know if that's right, and it may vary across life cycle. 460 00:24:39,760 --> 00:24:43,000 Speaker 1: So you know, we usually were reluctant to pin down 461 00:24:43,040 --> 00:24:44,640 Speaker 1: a number. I think it's fair to say that there's 462 00:24:44,640 --> 00:24:46,359 Speaker 1: a lot of things that are going on we usually 463 00:24:46,400 --> 00:24:50,040 Speaker 1: say implicitly that are not People aren't explicitly aware of 464 00:24:50,280 --> 00:24:52,040 Speaker 1: enough enough to make it very interesting. 465 00:24:52,040 --> 00:24:54,840 Speaker 2: So whenever I hear people talk about, you know, things 466 00:24:54,880 --> 00:24:57,280 Speaker 2: happening within the brain that you're not aware of, I 467 00:24:57,280 --> 00:25:01,479 Speaker 2: always think of the split brain experiments and tell us 468 00:25:01,480 --> 00:25:04,600 Speaker 2: a little bit, what does that reveal about our decision 469 00:25:04,600 --> 00:25:05,360 Speaker 2: making process. 470 00:25:05,359 --> 00:25:08,800 Speaker 1: So the split brain was actually first explored by Roger 471 00:25:08,840 --> 00:25:12,760 Speaker 1: Sperry at Caltech actually in his student Mike Zaniga, you know, 472 00:25:12,880 --> 00:25:16,200 Speaker 1: made a big chunk of career over out of it. 473 00:25:16,600 --> 00:25:19,480 Speaker 1: And so the split brain patients means they don't have 474 00:25:19,600 --> 00:25:21,800 Speaker 1: much communication between left and right hemispheres. 475 00:25:21,840 --> 00:25:27,880 Speaker 2: Corpus colosum is that right, So these are the one 476 00:25:27,920 --> 00:25:31,720 Speaker 2: I remember was it was some seizure or epilepsy, and 477 00:25:32,000 --> 00:25:36,160 Speaker 2: they found cutting that stop the seizures. But then your 478 00:25:36,240 --> 00:25:39,600 Speaker 2: left brain and your right brain don't really communicate anymore exactly. 479 00:25:39,960 --> 00:25:42,760 Speaker 1: So for example, so if you have a breakdown of 480 00:25:42,760 --> 00:25:47,679 Speaker 1: corpus closum, the right and left aren't really communicating despite 481 00:25:47,720 --> 00:25:50,760 Speaker 1: the right brain left brain. Most modern ner as signists 482 00:25:50,760 --> 00:25:53,720 Speaker 1: don't think there's that much specialization. There's some interesting kinds, 483 00:25:53,760 --> 00:25:57,919 Speaker 1: but one kind that's pretty rugged is languages mostly in 484 00:25:58,000 --> 00:26:00,520 Speaker 1: the left brain and regions called broke because area of 485 00:26:00,520 --> 00:26:03,120 Speaker 1: Wernicke's area. And we know that because you know, when 486 00:26:03,160 --> 00:26:05,240 Speaker 1: you have specialized damage in that area, you can see 487 00:26:05,240 --> 00:26:08,240 Speaker 1: people start to talk differently, like they can remember they 488 00:26:08,240 --> 00:26:09,119 Speaker 1: can't remember words. 489 00:26:09,119 --> 00:26:12,320 Speaker 2: But the aphasia, yeah, I remember reading about people who 490 00:26:12,320 --> 00:26:15,840 Speaker 2: can speak, could write, but couldn't read. Just all sorts 491 00:26:15,880 --> 00:26:18,600 Speaker 2: of wacky things happen when when those two areas are 492 00:26:18,640 --> 00:26:19,639 Speaker 2: down correct exactly. 493 00:26:19,680 --> 00:26:22,399 Speaker 1: So there are these very localized, pretty well understood A phaseias 494 00:26:22,400 --> 00:26:26,200 Speaker 1: that have to do with local damage. So there's there's 495 00:26:26,200 --> 00:26:28,280 Speaker 1: often what we call plasticity where another part of the 496 00:26:28,320 --> 00:26:30,480 Speaker 1: brain will take over. So if you had some damage 497 00:26:30,640 --> 00:26:32,760 Speaker 1: as a young child, it might be that the A phaseia, 498 00:26:33,320 --> 00:26:35,720 Speaker 1: you know, another another part of their brain like takes 499 00:26:35,720 --> 00:26:38,320 Speaker 1: over that function. But if it happens later in life, 500 00:26:38,440 --> 00:26:42,600 Speaker 1: not so anyway. So language is somewhat specialized the left region. So, 501 00:26:42,720 --> 00:26:47,359 Speaker 1: for example, if someone with a and the sensory systems 502 00:26:47,359 --> 00:26:49,920 Speaker 1: are contralateral, so the right side of the brain sees 503 00:26:49,960 --> 00:26:52,320 Speaker 1: the left side of a picture, left side sees the 504 00:26:52,359 --> 00:26:55,520 Speaker 1: right side. So suppose I show you on the left 505 00:26:55,520 --> 00:26:59,760 Speaker 1: of a picture a picture of a friend of yours, 506 00:27:00,359 --> 00:27:03,960 Speaker 1: and I asked the person, if you see this friend 507 00:27:04,000 --> 00:27:06,480 Speaker 1: of yours, what might what what gesture might you do? 508 00:27:06,560 --> 00:27:08,480 Speaker 1: Or what might you if you see a friend here 509 00:27:08,560 --> 00:27:10,760 Speaker 1: as opposed to a house or a shovel, what would 510 00:27:10,760 --> 00:27:14,280 Speaker 1: you do? And the person waves their hand and then 511 00:27:14,359 --> 00:27:16,520 Speaker 1: you ask them why did you wave your hand? Now, 512 00:27:16,560 --> 00:27:18,639 Speaker 1: the left side of the brain has to answer the 513 00:27:18,720 --> 00:27:21,640 Speaker 1: question because that's the language area. But the left side 514 00:27:21,640 --> 00:27:24,439 Speaker 1: doesn't know that the right side saw a friend and 515 00:27:24,480 --> 00:27:28,200 Speaker 1: that's why they waved. So the left side makes stuff. 516 00:27:27,960 --> 00:27:31,840 Speaker 2: Up, confabulates an explanation for why they're waiting exactly. 517 00:27:31,880 --> 00:27:33,880 Speaker 1: It's like the publicist for you know, for a very 518 00:27:33,920 --> 00:27:37,359 Speaker 1: guilty person and or Mike is not get calls it 519 00:27:37,359 --> 00:27:41,359 Speaker 1: the interpreter. So the interpreter says, I don't really know why, 520 00:27:41,480 --> 00:27:43,760 Speaker 1: so I'll kind of make give a plausible answer, and 521 00:27:43,800 --> 00:27:46,440 Speaker 1: they'll say something like, oh, I saw somebody I knew 522 00:27:46,920 --> 00:27:51,160 Speaker 1: walking by out the window outside. So that's an example 523 00:27:51,160 --> 00:27:54,119 Speaker 1: of where we know what the brain saw and why 524 00:27:54,680 --> 00:27:56,960 Speaker 1: the wave occurred, but the left part of the brain 525 00:27:56,960 --> 00:27:58,240 Speaker 1: doesn't know that. 526 00:27:58,400 --> 00:28:01,840 Speaker 2: That's really that's really fascinating. Let's stay with the idea 527 00:28:01,920 --> 00:28:05,440 Speaker 2: of tracking eye movement. So you could do this with glasses. 528 00:28:05,480 --> 00:28:08,400 Speaker 2: You can do with this with a computer. When you're 529 00:28:08,440 --> 00:28:12,400 Speaker 2: tracking eye movement, asking people about, hey, would you purchase 530 00:28:12,480 --> 00:28:15,680 Speaker 2: this product? How big of a tael is it? When 531 00:28:15,720 --> 00:28:18,040 Speaker 2: they look at the price and is it something they 532 00:28:18,200 --> 00:28:20,800 Speaker 2: just kind of glance at or is it a repeated 533 00:28:20,960 --> 00:28:23,359 Speaker 2: and obvious they're focusing on the cost. 534 00:28:23,720 --> 00:28:26,119 Speaker 1: There's there's sort of two interesting markers. For number one, 535 00:28:26,160 --> 00:28:28,159 Speaker 1: it's not that big of a tell. So if we 536 00:28:28,240 --> 00:28:30,879 Speaker 1: try to predict whether they're going to actually buy something, 537 00:28:31,000 --> 00:28:34,280 Speaker 1: we might get say forty two percent right, and with 538 00:28:34,400 --> 00:28:37,800 Speaker 1: the eye tracking data it might get up to like 539 00:28:37,960 --> 00:28:42,600 Speaker 1: fifty four, you know. So as academics we think that's 540 00:28:42,720 --> 00:28:44,840 Speaker 1: kind of a modest effect size. Now, if you're running 541 00:28:44,840 --> 00:28:47,200 Speaker 1: a business and you want a two percent lift and 542 00:28:47,240 --> 00:28:51,160 Speaker 1: purchase maybe a billion dollars, right, So sometimes we're a 543 00:28:51,160 --> 00:28:53,880 Speaker 1: little cautious as academics about is this a big deal 544 00:28:53,960 --> 00:28:55,880 Speaker 1: or not? I'm going to where's some of these things? 545 00:28:55,880 --> 00:28:57,560 Speaker 1: The same in the world of nudges and so on. 546 00:28:57,640 --> 00:29:00,680 Speaker 1: Sometimes a small you know what, a half increase and 547 00:29:00,720 --> 00:29:04,280 Speaker 1: get out the vote. If we could do that, you know, scientifically, 548 00:29:04,360 --> 00:29:08,200 Speaker 1: may well decide an election. Right anyway, So the lift 549 00:29:08,240 --> 00:29:10,800 Speaker 1: is not that big, but the two taels are basically 550 00:29:10,880 --> 00:29:14,440 Speaker 1: looking at the price, and the other is refixation, which 551 00:29:14,480 --> 00:29:17,680 Speaker 1: basically means not just looking once but going back and forth. 552 00:29:18,080 --> 00:29:21,520 Speaker 1: You know. It's the it's the rapid brain equivalent on 553 00:29:21,600 --> 00:29:24,520 Speaker 1: a one or two second basis of say a couple 554 00:29:24,560 --> 00:29:26,800 Speaker 1: who's shopping for a house, going to look at a 555 00:29:26,800 --> 00:29:29,240 Speaker 1: second time and a third time, you know, the repeated looking. 556 00:29:29,720 --> 00:29:33,160 Speaker 2: Right, usually a good signal exactly tells you the serious Huh. 557 00:29:33,200 --> 00:29:37,600 Speaker 2: That's really interesting. So give us some examples of what 558 00:29:37,680 --> 00:29:41,120 Speaker 2: the studies or the experiments look like. When you're doing 559 00:29:41,160 --> 00:29:44,240 Speaker 2: eye tracking, What are you trying to What parts of 560 00:29:44,280 --> 00:29:46,400 Speaker 2: the brain are you looking at? Or is it just 561 00:29:46,880 --> 00:29:50,040 Speaker 2: the eye tracking? Is it is this by itself or 562 00:29:50,040 --> 00:29:54,320 Speaker 2: can you combine this with other types of neuroeconomics. 563 00:29:54,480 --> 00:29:57,320 Speaker 1: Yeah, So, actually the eye trackers we use, which are 564 00:29:57,640 --> 00:30:02,840 Speaker 1: commercially made for some iis basically and sometimes for clinical use, 565 00:30:03,480 --> 00:30:06,320 Speaker 1: they use cameras to look at what the where the 566 00:30:06,320 --> 00:30:08,120 Speaker 1: eye is looking and they sync that up with where 567 00:30:08,120 --> 00:30:13,160 Speaker 1: on the computer screen you're looking. And so besides the 568 00:30:13,320 --> 00:30:16,040 Speaker 1: location of where the eyes are looking, you also measure 569 00:30:16,080 --> 00:30:20,240 Speaker 1: pupil dilation. And pupil dilation turns out to be, you know, 570 00:30:20,280 --> 00:30:21,800 Speaker 1: the eyes that they went into the soul, so that 571 00:30:21,920 --> 00:30:25,960 Speaker 1: the pupils actually generate a lot of information. Although it's 572 00:30:26,160 --> 00:30:29,280 Speaker 1: it's crude, what the people dilation is telling you is 573 00:30:29,320 --> 00:30:32,400 Speaker 1: about cognitive difficulty. Am I having a hard time thinking 574 00:30:32,400 --> 00:30:36,600 Speaker 1: about this? And arousal, which again may be negative or positive. 575 00:30:36,640 --> 00:30:39,600 Speaker 2: It's like, so wide pupil is you aroused. 576 00:30:41,080 --> 00:30:46,160 Speaker 1: Exactly exactly? And so I think if you train yourself 577 00:30:46,240 --> 00:30:49,240 Speaker 1: and maybe depending on the color of the eyes, you 578 00:30:49,320 --> 00:30:51,920 Speaker 1: might be able to tell, like a poker player might 579 00:30:51,960 --> 00:30:55,719 Speaker 1: be able to train themselves with a to notice pupil dilation, 580 00:30:56,080 --> 00:30:58,360 Speaker 1: but just in case. That's why poker players often will 581 00:30:58,360 --> 00:31:03,360 Speaker 1: wear glasses because these unglasses, right, Because the idea is, 582 00:31:03,360 --> 00:31:05,320 Speaker 1: if you look at your cards and you have two 583 00:31:05,400 --> 00:31:09,480 Speaker 1: ass your people will dilate like and it might be 584 00:31:09,520 --> 00:31:11,280 Speaker 1: hard to see with the naked eye, but the machines 585 00:31:11,320 --> 00:31:13,000 Speaker 1: we use can definitely see it. That would be a 586 00:31:13,000 --> 00:31:15,800 Speaker 1: big jump, you know, a big tell. And so we're 587 00:31:15,840 --> 00:31:19,280 Speaker 1: able to use people dilation and I tracking to judge 588 00:31:19,280 --> 00:31:22,240 Speaker 1: things like cognitive difficulty. A lot of the early studdies 589 00:31:22,280 --> 00:31:25,240 Speaker 1: actually were used in game theory because in game theory, 590 00:31:25,280 --> 00:31:28,120 Speaker 1: the assumption is if I might want to see what 591 00:31:28,160 --> 00:31:31,560 Speaker 1: my opponent's payoff is in order to decide what they're 592 00:31:31,560 --> 00:31:34,600 Speaker 1: going to do. And if you ask people what are 593 00:31:34,640 --> 00:31:36,800 Speaker 1: you looking at on this computer screen? You know, there's 594 00:31:36,960 --> 00:31:39,440 Speaker 1: there's a four by four matrix of numbers, and I'm 595 00:31:39,440 --> 00:31:41,440 Speaker 1: trying to think of what you're going to do. There's 596 00:31:41,440 --> 00:31:43,680 Speaker 1: a lot to look at. And if you ask people 597 00:31:43,680 --> 00:31:45,560 Speaker 1: for a self report, they're not going to tell you 598 00:31:45,560 --> 00:31:47,320 Speaker 1: exactly what their eyes are during the whole time, they're 599 00:31:47,320 --> 00:31:51,640 Speaker 1: probably looking at forty two different things, sometimes very quickly. 600 00:31:51,920 --> 00:31:54,280 Speaker 1: Sometimes they're going back and looking again and again and again. 601 00:31:54,720 --> 00:31:57,560 Speaker 1: They just don't have conscious access to that process the 602 00:31:57,600 --> 00:31:58,800 Speaker 1: way that the eye tracking does. 603 00:31:59,280 --> 00:32:03,400 Speaker 2: So that's really fascinating that speaking to the brain but 604 00:32:03,560 --> 00:32:06,480 Speaker 2: not the person gives you a whole lot more insight 605 00:32:06,680 --> 00:32:12,440 Speaker 2: into the decision making process. Speaking generally, what does this 606 00:32:12,640 --> 00:32:19,800 Speaker 2: tell us about people, as you know, rational profit seeking 607 00:32:20,160 --> 00:32:23,720 Speaker 2: actors in the world of finance and investing. 608 00:32:24,400 --> 00:32:27,840 Speaker 1: I think it's useful to think about, say, young naive investors, 609 00:32:28,000 --> 00:32:29,959 Speaker 1: or that they may to be young, but people who 610 00:32:30,040 --> 00:32:33,360 Speaker 1: have less knowledge about the markets, and people who spend 611 00:32:33,400 --> 00:32:38,200 Speaker 1: a lot more time thinking about estimating fundamentals reading ten K's, 612 00:32:39,480 --> 00:32:43,320 Speaker 1: you know, having years of trading experience. Because another important 613 00:32:43,320 --> 00:32:46,680 Speaker 1: facts which we try to keep track of and biro 614 00:32:46,720 --> 00:32:51,120 Speaker 1: economics is that a lot of decisions and structures people 615 00:32:51,160 --> 00:32:54,080 Speaker 1: have to make are not things that we're necessarily evolved 616 00:32:54,120 --> 00:32:57,600 Speaker 1: to be particularly good at. But people are also extremely 617 00:32:57,640 --> 00:33:01,040 Speaker 1: good at learning and able, you know, to like collect 618 00:33:01,040 --> 00:33:05,920 Speaker 1: memories and distill things into into knowledge. So let me 619 00:33:05,960 --> 00:33:07,840 Speaker 1: turn to the concept of price bubbles because I think 620 00:33:07,840 --> 00:33:10,000 Speaker 1: that's a useful one. So we have a couple of 621 00:33:10,160 --> 00:33:12,840 Speaker 1: one fMRI study on price bubbles, and we have some 622 00:33:12,880 --> 00:33:16,040 Speaker 1: new stuff that includes skin conductive's measurement to see if 623 00:33:16,320 --> 00:33:17,960 Speaker 1: you know, can you kind of predict when a crash 624 00:33:18,040 --> 00:33:21,520 Speaker 1: is coming from people's hands, you know, reflecting nervousness. It 625 00:33:21,760 --> 00:33:24,400 Speaker 1: looks like we can predict a little, but not great. 626 00:33:24,720 --> 00:33:27,440 Speaker 1: You know, that's a high mountain to climb. What we 627 00:33:27,520 --> 00:33:31,640 Speaker 1: found in our first fMRI study about bubbles was people 628 00:33:31,680 --> 00:33:34,840 Speaker 1: trade an artificial asset, so we know the value, the 629 00:33:34,840 --> 00:33:37,840 Speaker 1: fundamental value the asset, which we never know in you know, 630 00:33:37,920 --> 00:33:41,400 Speaker 1: in natural markets, and that the price is completely what 631 00:33:41,440 --> 00:33:44,520 Speaker 1: they agree upon. So typically what happens is that the 632 00:33:44,600 --> 00:33:48,680 Speaker 1: fundamental value is a number that we control, which happens 633 00:33:48,720 --> 00:33:51,400 Speaker 1: to be fourteen, and the value the asset comes from 634 00:33:51,400 --> 00:33:53,400 Speaker 1: the fact that if you hold at the end of 635 00:33:53,400 --> 00:33:56,560 Speaker 1: a period of trading, you get a dividend, or you 636 00:33:56,600 --> 00:34:00,760 Speaker 1: can invest currency in risk free bonds, and so the 637 00:34:00,880 --> 00:34:03,880 Speaker 1: trade off between the risk free earnings and the value 638 00:34:03,880 --> 00:34:06,280 Speaker 1: of the dividends establishes an equlibrium price. It's a very 639 00:34:06,280 --> 00:34:11,440 Speaker 1: simple equation, and typically the price starts around fourteen, it 640 00:34:11,480 --> 00:34:14,360 Speaker 1: goes up to maybe twenty or thirty and then crashes. 641 00:34:14,719 --> 00:34:18,320 Speaker 1: And then in order to bring the experiments to a close, 642 00:34:18,400 --> 00:34:20,760 Speaker 1: we have them trade for fifty periods or thirty periods, 643 00:34:20,760 --> 00:34:22,799 Speaker 1: and at the end they were able to cash the 644 00:34:22,840 --> 00:34:24,080 Speaker 1: assets out at fourteen. 645 00:34:24,800 --> 00:34:26,719 Speaker 2: So what would you pay for an asset that you'll 646 00:34:26,760 --> 00:34:30,640 Speaker 2: get fourteen for correct after a series of dividends thirty 647 00:34:30,719 --> 00:34:32,480 Speaker 2: or fifty trading periods exactly. 648 00:34:32,800 --> 00:34:35,080 Speaker 1: And so put yourselves in the mind, said of somebody 649 00:34:35,080 --> 00:34:39,200 Speaker 1: who in period thirty one the price is sixty, and 650 00:34:39,239 --> 00:34:42,840 Speaker 1: you kind of know that in period fifty nineteen periods 651 00:34:42,840 --> 00:34:46,240 Speaker 1: from now it's going to be fourteen. So well, unless 652 00:34:46,280 --> 00:34:49,080 Speaker 1: you think it's going to go up to seventy five, right, 653 00:34:49,200 --> 00:34:53,920 Speaker 1: So it's true. In fact, that's very helpful for me. 654 00:34:54,040 --> 00:34:57,040 Speaker 1: So what we found from the brain was that there's 655 00:34:57,080 --> 00:34:59,279 Speaker 1: two interesting signals, soh sort with the more interesting one. 656 00:34:59,320 --> 00:35:01,880 Speaker 1: The other one's a little more obvious. The interesting signal 657 00:35:02,000 --> 00:35:06,600 Speaker 1: is people who sold before the bubble crash, which is 658 00:35:06,600 --> 00:35:08,719 Speaker 1: the smart thing to do. And again, the bubble crash 659 00:35:08,760 --> 00:35:10,839 Speaker 1: is not announced. It's something you only see a store 660 00:35:10,880 --> 00:35:13,360 Speaker 1: cooking back and of your mirror, right. 661 00:35:14,040 --> 00:35:16,120 Speaker 2: Same in natural markets exactly. 662 00:35:15,719 --> 00:35:18,080 Speaker 1: Just like a national markets, right, bubbles are only shown 663 00:35:18,120 --> 00:35:20,239 Speaker 1: in hindsight. Gene Falum has written a lot about this. 664 00:35:20,239 --> 00:35:23,040 Speaker 1: That's one reason he's skeptical that we should even talk 665 00:35:23,080 --> 00:35:25,320 Speaker 1: about bubbles, you know, as a scientific phenomens. 666 00:35:25,320 --> 00:35:28,440 Speaker 2: Okay, I think it goes too far with that, but anyway, anyway. 667 00:35:28,160 --> 00:35:30,759 Speaker 1: Yeah, you know what I mean. So it turns out 668 00:35:30,760 --> 00:35:33,080 Speaker 1: the people who are more likely to sell when the 669 00:35:33,120 --> 00:35:35,600 Speaker 1: price is at sixty and we know it's going to crash, 670 00:35:35,719 --> 00:35:40,080 Speaker 1: but we're not sure when have heightened activity and insular cortex, 671 00:35:40,719 --> 00:35:44,040 Speaker 1: which is another region that's involved in emotion and interception. 672 00:35:44,440 --> 00:35:46,120 Speaker 1: So interception means. 673 00:35:46,280 --> 00:35:49,240 Speaker 2: Knowing what's going on on the inside of your own body, 674 00:35:49,280 --> 00:35:50,720 Speaker 2: like a self awareness exactly. 675 00:35:50,760 --> 00:35:54,560 Speaker 1: So perception is the outside world. Interception is the brain's 676 00:35:54,600 --> 00:35:57,399 Speaker 1: like the body's ambassadorship to the brain, you know, knowing 677 00:35:57,440 --> 00:36:02,640 Speaker 1: if I'm nervous or And it's often activated by, particularly 678 00:36:02,680 --> 00:36:06,160 Speaker 1: by negative emotions. So if you see something disgusting, insula, 679 00:36:06,320 --> 00:36:08,719 Speaker 1: if you choke a person a little bit, or you 680 00:36:08,719 --> 00:36:11,080 Speaker 1: you know, you cut off the oxygen, not so it's dangerous, 681 00:36:11,080 --> 00:36:14,839 Speaker 1: but just to make them uncomfortable. Insula, financial uncertainty, the insula. 682 00:36:14,960 --> 00:36:17,840 Speaker 1: And so we think of the insula is the early 683 00:36:17,880 --> 00:36:20,600 Speaker 1: warning signal that there's going to be a crash. And 684 00:36:20,640 --> 00:36:23,439 Speaker 1: the other interesting brain region is nucleus the cummins, which 685 00:36:23,480 --> 00:36:28,040 Speaker 1: is basically a reward center and it's called straightum part 686 00:36:28,040 --> 00:36:31,399 Speaker 1: of basoganglia in the very center of the brain, and 687 00:36:31,440 --> 00:36:34,320 Speaker 1: that's active in the people who are fueling the bubble. 688 00:36:34,440 --> 00:36:38,319 Speaker 1: Like when the bubbles, you know, forming the people who 689 00:36:38,360 --> 00:36:41,520 Speaker 1: have the highest nucleus incumbans activity by the most. 690 00:36:41,680 --> 00:36:44,560 Speaker 2: So you have a run of traders participating in this, 691 00:36:44,719 --> 00:36:48,880 Speaker 2: and you could tell by the brain activity who's contributing 692 00:36:48,920 --> 00:36:51,600 Speaker 2: to the bubble and who's saying, this is getting crazy. 693 00:36:51,640 --> 00:36:54,240 Speaker 2: I want to take my chips off the tails now. 694 00:36:54,560 --> 00:36:57,960 Speaker 1: Number one, we can't tell with exquisite precision. You know, 695 00:36:58,000 --> 00:37:00,399 Speaker 1: you can sort of see these groups, and we're only 696 00:37:00,560 --> 00:37:03,760 Speaker 1: looking at this X post. So I think it's it's 697 00:37:03,800 --> 00:37:07,759 Speaker 1: conceivable but challenging to do this in real time, you know. 698 00:37:07,840 --> 00:37:10,520 Speaker 1: So there's you're watching the market unfold. You're doing real 699 00:37:10,560 --> 00:37:14,480 Speaker 1: time from eye measurement that can be done, and it's like, okay, 700 00:37:14,520 --> 00:37:17,359 Speaker 1: traders seven, nine and eleven, you know, we think they're 701 00:37:17,360 --> 00:37:20,200 Speaker 1: probably going to sell. There the skeptics, they're the bulls 702 00:37:20,719 --> 00:37:24,920 Speaker 1: and fourteen, seventeen and twenty one. Their new kidcombanis Activity. 703 00:37:24,960 --> 00:37:27,000 Speaker 1: Seems they're really all in. They're going to be forming 704 00:37:27,000 --> 00:37:28,480 Speaker 1: the bubble and so on and so on. I mean, 705 00:37:28,520 --> 00:37:30,520 Speaker 1: we're a few steps away from be able to do it, 706 00:37:30,560 --> 00:37:33,400 Speaker 1: but we see these what we call proofs of concept 707 00:37:33,640 --> 00:37:36,239 Speaker 1: like it can be done. It may take a few 708 00:37:36,280 --> 00:37:38,680 Speaker 1: million dollars if any donors are listening. 709 00:37:39,239 --> 00:37:42,360 Speaker 2: But it makes perfect sense that that is possible. Different 710 00:37:42,400 --> 00:37:47,279 Speaker 2: parts of the brain are responding to different inputs, and 711 00:37:47,320 --> 00:37:51,200 Speaker 2: it's consistent with what we've observed amongst sure, you know, 712 00:37:51,400 --> 00:37:55,919 Speaker 2: just various investors and traders. There are people with as 713 00:37:56,000 --> 00:37:59,720 Speaker 2: the you know, in the latter stages of a bull market, 714 00:38:00,360 --> 00:38:02,920 Speaker 2: they think it's just going to keep going forever and 715 00:38:02,960 --> 00:38:06,080 Speaker 2: they pile in. And the flip side of that, there 716 00:38:06,080 --> 00:38:10,600 Speaker 2: are people the famous irrational zuberance speech by Alan Greenspan 717 00:38:11,239 --> 00:38:13,800 Speaker 2: in nineteen ninety six. You still had a ton of 718 00:38:14,440 --> 00:38:18,640 Speaker 2: gains until the March two thousand and top. So some people, 719 00:38:19,320 --> 00:38:23,080 Speaker 2: I'm just curious what drives that. Now that you know 720 00:38:23,320 --> 00:38:26,080 Speaker 2: what to look for and how to measure it in 721 00:38:26,160 --> 00:38:28,920 Speaker 2: traders in real time, what do you think is the 722 00:38:29,000 --> 00:38:32,840 Speaker 2: underlying drivers of whether a person is going to be 723 00:38:32,920 --> 00:38:35,439 Speaker 2: participating in one tribe or the other. 724 00:38:36,440 --> 00:38:38,799 Speaker 1: That's a great question. I'll say a little tiny bit 725 00:38:38,840 --> 00:38:41,919 Speaker 1: more about that. You mentioned the term irrational exuberance, which 726 00:38:42,040 --> 00:38:44,560 Speaker 1: was coined, as I recall, by Bob Shiller in his 727 00:38:44,600 --> 00:38:45,520 Speaker 1: book about. 728 00:38:46,000 --> 00:38:51,920 Speaker 2: I think it was from the Irrational Zuberant speech. Schiller 729 00:38:51,960 --> 00:38:56,240 Speaker 2: may have helped Greenspan with that speech, if I'm remembering, 730 00:38:56,280 --> 00:38:58,960 Speaker 2: because I've seen I've seen both, whether it was Schiller's 731 00:38:59,000 --> 00:39:00,200 Speaker 2: phrase or green Span. 732 00:39:00,080 --> 00:39:02,759 Speaker 1: It maybe it maybe, you know, it's kind of some 733 00:39:03,120 --> 00:39:06,200 Speaker 1: you know, some apocryphal. You know, we're not sure exactly 734 00:39:06,200 --> 00:39:08,000 Speaker 1: who said it first, but certainly there was a kind 735 00:39:08,000 --> 00:39:10,200 Speaker 1: of meeting of the minds that this was useful. And 736 00:39:10,239 --> 00:39:12,719 Speaker 1: in fact, when we didn't we use the phrase in 737 00:39:12,760 --> 00:39:14,320 Speaker 1: our paper, but we didn't put it in the title. 738 00:39:14,360 --> 00:39:17,319 Speaker 1: It just seemed a little too unscientific. It's okay for 739 00:39:17,520 --> 00:39:20,080 Speaker 1: USA today or something. But this is the proceedings of 740 00:39:20,080 --> 00:39:23,279 Speaker 1: the National Academy of Sciences, you know, And but we 741 00:39:23,320 --> 00:39:26,200 Speaker 1: think of this nucleus incumbents activity. That's that's the measure 742 00:39:26,200 --> 00:39:30,000 Speaker 1: of irrational exuberance. And the irrational part is, you know, 743 00:39:30,040 --> 00:39:33,160 Speaker 1: when it's too high, you're gonna end up paying a 744 00:39:33,239 --> 00:39:37,160 Speaker 1: high price for something it crashes fast. So this irrational 745 00:39:37,239 --> 00:39:41,440 Speaker 1: is really in there. Literally. But yeah, and and also 746 00:39:41,480 --> 00:39:45,160 Speaker 1: we when I present this in academic summers and later 747 00:39:45,200 --> 00:39:48,799 Speaker 1: today i'm meeting some Caltech people, we talk about this 748 00:39:48,840 --> 00:39:52,320 Speaker 1: famous saying from Warren Buffett. I believe when people are afraid, 749 00:39:52,440 --> 00:39:56,040 Speaker 1: be greedy, when people ready be afraid. And this brain 750 00:39:56,080 --> 00:40:00,760 Speaker 1: areas like insula is similar to fear and greed and inclusivecumbents. 751 00:40:00,800 --> 00:40:02,439 Speaker 1: You know, it's about as close you're going to get 752 00:40:03,000 --> 00:40:06,719 Speaker 1: to brain areas matching what Warren Buffett had to say, 753 00:40:06,719 --> 00:40:08,840 Speaker 1: which was such a wise thought. 754 00:40:08,600 --> 00:40:11,719 Speaker 2: So you really kind of answered the question I was 755 00:40:11,760 --> 00:40:15,680 Speaker 2: about to ask, which is why has behavioral economics been 756 00:40:15,760 --> 00:40:21,640 Speaker 2: so successful describing decision making where traditional economics seems to 757 00:40:21,760 --> 00:40:25,840 Speaker 2: have faltered. But what you're really saying is we don't 758 00:40:25,880 --> 00:40:27,880 Speaker 2: know what's going on in our brain when we're making 759 00:40:27,920 --> 00:40:32,160 Speaker 2: decisions as individuals, And when you look underneath the hood, 760 00:40:32,160 --> 00:40:35,279 Speaker 2: it turns out there's a lot more things happening than 761 00:40:35,840 --> 00:40:38,320 Speaker 2: at least classical economics seems to imply. 762 00:40:38,800 --> 00:40:43,680 Speaker 1: Yes, exactly exactly. And also, this isn't something we've carefully researched, 763 00:40:43,680 --> 00:40:46,000 Speaker 1: but I think it's a good speculation for your audience, 764 00:40:46,000 --> 00:40:48,560 Speaker 1: which is like when I was going to Chicago in 765 00:40:48,560 --> 00:40:51,719 Speaker 1: the late seventies, all my gratitude and friends were also 766 00:40:51,840 --> 00:40:54,920 Speaker 1: kind of critics of Nobody liked Bay of economics at 767 00:40:54,920 --> 00:40:58,640 Speaker 1: that time, though oh really, oh yeah it was you know, 768 00:40:58,680 --> 00:41:00,560 Speaker 1: people said things like I think, you know, I'm worried 769 00:41:00,600 --> 00:41:02,719 Speaker 1: you might be ruining your career because you switched out 770 00:41:02,719 --> 00:41:06,200 Speaker 1: of finance and well, and what it was was there 771 00:41:06,239 --> 00:41:10,120 Speaker 1: was a series of critical questions which were, but if 772 00:41:10,160 --> 00:41:14,040 Speaker 1: people make all these mistakes, couldn't someone profit from you know, 773 00:41:14,719 --> 00:41:18,560 Speaker 1: arbitrage or from selling them crappy goods, Like well, it 774 00:41:18,560 --> 00:41:21,359 Speaker 1: seems like that may happen, you know, Or if people 775 00:41:21,400 --> 00:41:23,400 Speaker 1: make these mistakes, don't they learn over time not to 776 00:41:23,440 --> 00:41:25,640 Speaker 1: make mistakes? That may also happen, and maybe that there's 777 00:41:25,640 --> 00:41:27,880 Speaker 1: a sucker born every minute. But there's a you know, 778 00:41:27,920 --> 00:41:31,120 Speaker 1: a generational process, and markets are always filled with some 779 00:41:31,160 --> 00:41:35,680 Speaker 1: combination of new investors or you know, sovereign funds of 780 00:41:35,719 --> 00:41:38,880 Speaker 1: people who aren't very savvy about markets or something like that. 781 00:41:39,360 --> 00:41:41,160 Speaker 1: So early in the history of behaval economics, there was 782 00:41:41,200 --> 00:41:44,839 Speaker 1: really a lot of hostility about it, and then we 783 00:41:44,880 --> 00:41:48,960 Speaker 1: gradually one thing about Chicago, and the economics profession in 784 00:41:48,960 --> 00:41:53,440 Speaker 1: general is data do win arguments, so ideology will often persist, 785 00:41:54,280 --> 00:41:57,400 Speaker 1: like for Gene Fama, for example, he's he'll always be 786 00:41:57,440 --> 00:42:02,160 Speaker 1: skeptical about behavioral finance for his own reasons, and you know, 787 00:42:02,280 --> 00:42:06,640 Speaker 1: their ideas. But eventually data went arguments, and there were 788 00:42:06,880 --> 00:42:09,120 Speaker 1: you know, there were just so many anomalies and ways 789 00:42:09,120 --> 00:42:12,200 Speaker 1: in which investors were making mistakes. And it wasn't just 790 00:42:12,239 --> 00:42:16,840 Speaker 1: small investors, you know, who were refinancing their mortgage mistakenly. 791 00:42:16,880 --> 00:42:19,480 Speaker 1: It was you know, some of these implicit things maybe 792 00:42:19,719 --> 00:42:23,239 Speaker 1: very big, you know, like venture capitalists joked about how 793 00:42:23,600 --> 00:42:25,840 Speaker 1: well you know when I think of Mark Zuckerberg and 794 00:42:25,840 --> 00:42:28,200 Speaker 1: a hoodie, and that's kind of my template for a 795 00:42:28,200 --> 00:42:31,960 Speaker 1: good founder to invest tens of millions of dollars. Hey, like, 796 00:42:32,480 --> 00:42:34,839 Speaker 1: that's not as sophisticated, that's not how economics. 797 00:42:35,200 --> 00:42:38,960 Speaker 2: And I recall reading one of the papers Bob Schiller 798 00:42:39,040 --> 00:42:42,879 Speaker 2: wrote was looking at divinend yield and saying, if if 799 00:42:42,960 --> 00:42:47,080 Speaker 2: markets are fully pricing in all data, why does this 800 00:42:47,160 --> 00:42:49,719 Speaker 2: divin and yield swing around so much? It should be 801 00:42:49,800 --> 00:42:53,440 Speaker 2: much more consistent than this correct, but apparently it's not. 802 00:42:54,320 --> 00:42:57,200 Speaker 2: I just I was very amused by Fama and Schiller 803 00:42:57,320 --> 00:43:00,480 Speaker 2: being awarded the Nobel together. It's almost says if the 804 00:43:00,520 --> 00:43:04,400 Speaker 2: committee said, look, markets are kind of efficient, and except 805 00:43:04,400 --> 00:43:06,920 Speaker 2: when they go crazy, you two guys work it out. 806 00:43:07,080 --> 00:43:10,279 Speaker 1: Yes, yeah, yeah, it was quite a It was kind 807 00:43:10,280 --> 00:43:13,600 Speaker 1: of a charming and I think sensible award for that reason. 808 00:43:13,719 --> 00:43:16,960 Speaker 1: And the you know, the journalist said like, well is 809 00:43:17,000 --> 00:43:19,839 Speaker 1: there you know, one person says a is true, one 810 00:43:19,880 --> 00:43:21,759 Speaker 1: says A is not always true? Like how could you 811 00:43:21,800 --> 00:43:24,239 Speaker 1: give that award? The answers they both made made a 812 00:43:24,239 --> 00:43:27,520 Speaker 1: lot of progress, you know, in different ways. 813 00:43:27,880 --> 00:43:31,000 Speaker 2: Let's talk about some of the other ways that we 814 00:43:31,080 --> 00:43:35,040 Speaker 2: can look inside. Are we looking at things like adrenaline 815 00:43:35,120 --> 00:43:38,440 Speaker 2: or dopamine or any of the sort of hormones that 816 00:43:38,520 --> 00:43:41,960 Speaker 2: seem to affect our behavior when when we're trying to 817 00:43:42,000 --> 00:43:43,200 Speaker 2: analyze decision making. 818 00:43:43,640 --> 00:43:47,960 Speaker 1: Yeah, so, actually that's a very good question, Barry. New 819 00:43:48,040 --> 00:43:51,600 Speaker 1: economics uses a lot of different methods. The fMRI is 820 00:43:51,640 --> 00:43:54,200 Speaker 1: sort of like, you know the movie star and a 821 00:43:54,200 --> 00:43:56,880 Speaker 1: family with four sisters, you know, the glamorous one that 822 00:43:56,880 --> 00:43:59,759 Speaker 1: everyone pays attention to, but it's actually high maintenance. And 823 00:43:59,800 --> 00:44:02,120 Speaker 1: then but all the other siblings are you know, kind 824 00:44:02,120 --> 00:44:05,800 Speaker 1: of contributing in some interesting way. So pharmacology is something 825 00:44:05,800 --> 00:44:07,319 Speaker 1: people are really interested in. 826 00:44:07,480 --> 00:44:11,920 Speaker 2: Meaning specifically pharmacology drugs that aren't yes, pharmacolo. 827 00:44:11,880 --> 00:44:14,800 Speaker 1: So pharmacology is drugs, but some of those, for example, 828 00:44:14,840 --> 00:44:18,960 Speaker 1: el dopa will actually ramp up dopamine levels and you 829 00:44:18,960 --> 00:44:20,560 Speaker 1: can see if some interesting things happen. 830 00:44:20,719 --> 00:44:23,719 Speaker 2: El Dopa is a drug you can consume correct in 831 00:44:23,800 --> 00:44:25,280 Speaker 2: order to raise your dopamine exactly. 832 00:44:25,440 --> 00:44:29,000 Speaker 1: So it's it's al Dopa's basically administrative. So Parkinson's patients 833 00:44:29,600 --> 00:44:33,279 Speaker 1: have a degradation of dopamine and so to kind of 834 00:44:33,360 --> 00:44:36,000 Speaker 1: ramp them up to normal levels. Al dopa is often 835 00:44:36,080 --> 00:44:37,240 Speaker 1: used in treatment. 836 00:44:37,440 --> 00:44:40,880 Speaker 2: Pharmacology is one what are some of the other forces, 837 00:44:41,160 --> 00:44:41,400 Speaker 2: So we. 838 00:44:41,760 --> 00:44:45,839 Speaker 1: Do look at neurotransmitters like oxytocin, argoniine Vasopressint is one 839 00:44:45,840 --> 00:44:46,520 Speaker 1: that we've studied. 840 00:44:46,840 --> 00:44:51,280 Speaker 2: Isytocin sounds a lot like OxyContin any correct overlap. 841 00:44:51,160 --> 00:44:56,600 Speaker 1: No exactually, so oxytocin is is sometimes called as like 842 00:44:56,640 --> 00:45:00,040 Speaker 1: an affiliation hormone. So for example, if you get a 843 00:45:00,080 --> 00:45:02,960 Speaker 1: really pleasurable massage, you might feel a surge of oxytocin. 844 00:45:04,280 --> 00:45:09,480 Speaker 1: When my wife was giving birth, they often to induce labor. 845 00:45:09,520 --> 00:45:14,479 Speaker 1: They often give somebody synthetic oxytocin, and oxytocin is also 846 00:45:14,520 --> 00:45:16,919 Speaker 1: produced after birth and when the mom is first coming, 847 00:45:16,960 --> 00:45:20,120 Speaker 1: the baby and probably the dad, although maybe less. You know, 848 00:45:20,160 --> 00:45:22,640 Speaker 1: it's this very pleasurable thing that makes you want to 849 00:45:22,840 --> 00:45:26,600 Speaker 1: like hug somebody and feel affiliated. It's affiliated. It's this 850 00:45:26,680 --> 00:45:29,800 Speaker 1: sort of bio term. So there's a bunch of studies 851 00:45:29,800 --> 00:45:34,600 Speaker 1: on oxidosins yesting that improved trust. But there's a cautionary tale, 852 00:45:34,640 --> 00:45:37,759 Speaker 1: which is me and some colleagues went back and looked 853 00:45:37,760 --> 00:45:41,840 Speaker 1: at those carefully, and it seems that giving people artificial 854 00:45:41,960 --> 00:45:45,400 Speaker 1: is giving people oxytocin for a modest dose and then 855 00:45:45,440 --> 00:45:48,280 Speaker 1: see what happens, you know, an hour later. It improves 856 00:45:48,320 --> 00:45:54,080 Speaker 1: trust a little bit, but it's scientifically very very tricky 857 00:45:54,200 --> 00:45:56,840 Speaker 1: and some of the standard results if you do the 858 00:45:56,880 --> 00:45:59,680 Speaker 1: same exact experiment over again, you just don't always get 859 00:45:59,680 --> 00:46:02,600 Speaker 1: the same result. So we don't know how sturdy oxytocin is. 860 00:46:03,000 --> 00:46:04,880 Speaker 2: What What are some of the other chemicals you mentioned 861 00:46:04,880 --> 00:46:06,200 Speaker 2: neurotrano When. 862 00:46:06,040 --> 00:46:08,799 Speaker 1: We studied I'll say a little bit of was argonon vasopressin, 863 00:46:09,440 --> 00:46:13,799 Speaker 1: So that's another hormone which is similar to oxytocin, and 864 00:46:13,800 --> 00:46:18,000 Speaker 1: that when when animals are bonding in groups, this organon 865 00:46:18,080 --> 00:46:20,880 Speaker 1: vasopressant sort of you know, you'll get a surge and 866 00:46:21,200 --> 00:46:21,759 Speaker 1: it shows that. 867 00:46:22,040 --> 00:46:24,120 Speaker 2: So when you say bonding in groups, I'm thinking of 868 00:46:24,160 --> 00:46:27,520 Speaker 2: a wolf pack or a hyena pack, where yes, they're 869 00:46:27,600 --> 00:46:32,399 Speaker 2: cooperative species that work together, and there are chemicals that 870 00:46:33,280 --> 00:46:35,880 Speaker 2: contribute to that. Is that Is that what we're suggesting exactly? 871 00:46:35,920 --> 00:46:36,920 Speaker 1: So part of me. 872 00:46:37,120 --> 00:46:42,080 Speaker 2: Wants to say we're just meat sex operating obliviously to 873 00:46:42,160 --> 00:46:46,600 Speaker 2: what's going on underneath our skin, where we think it's 874 00:46:46,640 --> 00:46:48,880 Speaker 2: free will, But it sounds like there's a lot of 875 00:46:48,880 --> 00:46:53,720 Speaker 2: things happening below the surface that's really influencing our decision making. 876 00:46:53,880 --> 00:46:56,560 Speaker 1: Yeah, oh absolutely. I mean think about things like breathing. 877 00:46:56,760 --> 00:47:00,480 Speaker 1: You know, breathing is so automatic, then when we stop 878 00:47:00,560 --> 00:47:02,640 Speaker 1: and do sort of breath work and try to think 879 00:47:02,680 --> 00:47:04,840 Speaker 1: about it, like the Navy seals might have a breathing 880 00:47:04,840 --> 00:47:07,640 Speaker 1: exercise to calm down before a terrifying thing they have 881 00:47:07,719 --> 00:47:10,160 Speaker 1: to take. You know, it actually takes a lot of 882 00:47:10,200 --> 00:47:13,200 Speaker 1: executive function to think about breathing because we never have. 883 00:47:13,160 --> 00:47:14,320 Speaker 2: To because it's automated. 884 00:47:14,520 --> 00:47:16,800 Speaker 1: Because it's so automated. So the fact that it's actually 885 00:47:17,280 --> 00:47:19,520 Speaker 1: grabs a lot of attention is because the automation is 886 00:47:19,920 --> 00:47:23,080 Speaker 1: we've completely flipped back in the opposite situation. Let me 887 00:47:23,120 --> 00:47:26,040 Speaker 1: tell you Urgan investor Pressen's study. We did. So. There's 888 00:47:26,080 --> 00:47:28,359 Speaker 1: a game similar to prison die Lemma, but not the same, 889 00:47:28,800 --> 00:47:31,480 Speaker 1: called the Stag hunt game, and the idea is two 890 00:47:31,480 --> 00:47:34,439 Speaker 1: people decide to show up in the morning and hunt 891 00:47:34,520 --> 00:47:37,200 Speaker 1: for a stag is a very old fashioned name from 892 00:47:37,280 --> 00:47:39,920 Speaker 1: the Jean jau Bussau and the sixteen hundreds. 893 00:47:40,040 --> 00:47:43,439 Speaker 2: We're talking about a male elk or deer. 894 00:47:43,520 --> 00:47:45,480 Speaker 1: Yeah, an elk or deer. Yeah. The point of the 895 00:47:45,480 --> 00:47:47,799 Speaker 1: stag is it's so big that no one person can't 896 00:47:47,800 --> 00:47:50,680 Speaker 1: catch themselves. One person has to spot and the other 897 00:47:50,719 --> 00:47:53,799 Speaker 1: a shoot or something like that, or they cannot show 898 00:47:53,840 --> 00:47:55,600 Speaker 1: up in the morning at the appointed spot and just 899 00:47:55,680 --> 00:47:58,440 Speaker 1: hunt for rabbits on their own. And so the structure 900 00:47:58,480 --> 00:48:00,960 Speaker 1: of the game when we do it with money or 901 00:48:01,080 --> 00:48:05,759 Speaker 1: reward with animals is you get one point if you 902 00:48:05,880 --> 00:48:08,440 Speaker 1: just go for rabbit. If you both hunt for stag, 903 00:48:08,520 --> 00:48:10,319 Speaker 1: you get two if you hunt for stag. But if 904 00:48:10,360 --> 00:48:13,080 Speaker 1: you show up by yourself prepared to hunt for stag, 905 00:48:13,200 --> 00:48:16,120 Speaker 1: you can't catch it and you get zero. And so 906 00:48:16,200 --> 00:48:19,920 Speaker 1: the choosing a rabbit is choosing one and not helping 907 00:48:19,920 --> 00:48:22,719 Speaker 1: your friend both showing up for STAG is better for 908 00:48:22,760 --> 00:48:25,280 Speaker 1: the both of them, but they have to somehow coordinate 909 00:48:25,320 --> 00:48:28,000 Speaker 1: that activity. And so what we found was when you 910 00:48:28,040 --> 00:48:32,839 Speaker 1: give people this AVP and it's a crossover design, which 911 00:48:32,880 --> 00:48:34,759 Speaker 1: means sometimes they get AVP and sometimes they get a 912 00:48:34,760 --> 00:48:38,440 Speaker 1: placebo because there's a well known placebo effect where if 913 00:48:38,440 --> 00:48:40,319 Speaker 1: they think maybe they got the a VP, it might 914 00:48:40,719 --> 00:48:44,920 Speaker 1: subconsciously affect the behavior. So we always control for placebo effects, 915 00:48:44,920 --> 00:48:46,680 Speaker 1: just like in drug trials, you know, the same thing 916 00:48:46,760 --> 00:48:50,160 Speaker 1: very routine. When you give them a VP, they're more 917 00:48:50,239 --> 00:48:53,759 Speaker 1: likely to choose STAG, which is the socially risky and 918 00:48:53,840 --> 00:48:58,040 Speaker 1: beneficial thing. It's like it generates this willingness to join 919 00:48:58,080 --> 00:49:00,000 Speaker 1: the group in a way that's going to help better 920 00:49:00,000 --> 00:49:03,839 Speaker 1: everybody if another if you people join. And the other 921 00:49:03,880 --> 00:49:07,040 Speaker 1: thing that was really nice in this paper was we 922 00:49:07,200 --> 00:49:10,080 Speaker 1: also used fhor Mari. So we had two groups of 923 00:49:10,120 --> 00:49:14,000 Speaker 1: people with administering a VP, one group of scan and 924 00:49:14,040 --> 00:49:16,080 Speaker 1: one was not scan, which is just to see, like 925 00:49:16,120 --> 00:49:18,239 Speaker 1: to replicate, do you get the same behavioral thing if 926 00:49:18,280 --> 00:49:20,280 Speaker 1: they're not. You know, boom boom boom in the scanner 927 00:49:20,840 --> 00:49:24,399 Speaker 1: and in the scanner you see activity globist palatue, which 928 00:49:24,440 --> 00:49:27,719 Speaker 1: is known to be it's a small region. It's not 929 00:49:27,840 --> 00:49:29,960 Speaker 1: one of the more familiar areas you know that show 930 00:49:30,040 --> 00:49:32,759 Speaker 1: up a lots over and over in economics like Bezo Ganglia, 931 00:49:33,400 --> 00:49:38,360 Speaker 1: A Magdola, Nsula, PFC. But you do see activity globist 932 00:49:38,400 --> 00:49:44,279 Speaker 1: paladue when people under a VP are choosing STAG, So 933 00:49:44,320 --> 00:49:46,680 Speaker 1: it looks like the the a VP is sort of 934 00:49:46,680 --> 00:49:48,320 Speaker 1: promoting this STAG choice. 935 00:49:48,600 --> 00:49:52,440 Speaker 2: But when we see people working cooperatively, you see a 936 00:49:52,520 --> 00:49:56,319 Speaker 2: similar neurotransmitter as you do in the. 937 00:49:56,239 --> 00:49:58,920 Speaker 1: Path and it's and it's and it's causal. Right, So 938 00:49:58,960 --> 00:50:01,040 Speaker 1: these are the group of people and sometimes they just 939 00:50:01,080 --> 00:50:01,440 Speaker 1: get this. 940 00:50:01,480 --> 00:50:05,080 Speaker 2: Drug and it makes them want to cooperate. 941 00:50:04,719 --> 00:50:06,399 Speaker 1: And it makes them want to cooperate in a way 942 00:50:06,440 --> 00:50:08,600 Speaker 1: that with this risky it benefits the group. But we 943 00:50:08,719 --> 00:50:12,879 Speaker 1: sometimes think of it it overcomes their inhibition to be well, 944 00:50:12,960 --> 00:50:14,600 Speaker 1: I don't know if you're going to choose STAGG, and 945 00:50:14,760 --> 00:50:16,120 Speaker 1: I don't know if you're going to show up well. 946 00:50:16,160 --> 00:50:19,360 Speaker 2: The prisoner's dilemma is you're always better off throwing the 947 00:50:19,360 --> 00:50:21,240 Speaker 2: other person under the bush. 948 00:50:21,400 --> 00:50:24,560 Speaker 1: This is not that because here's the other person helps out, 949 00:50:24,600 --> 00:50:26,640 Speaker 1: you want to help out too. It's the best response. 950 00:50:26,800 --> 00:50:29,640 Speaker 1: So it's different structurally than the prison's dilemma. 951 00:50:29,719 --> 00:50:33,560 Speaker 2: So I keep coming back every time I read a 952 00:50:33,640 --> 00:50:37,799 Speaker 2: new anything about behavioral finance, new economics, anything about this. 953 00:50:38,600 --> 00:50:41,399 Speaker 2: I can help but come back to the conclusion that 954 00:50:42,520 --> 00:50:47,520 Speaker 2: all of our evolutionary biology has led us to a 955 00:50:47,680 --> 00:50:54,080 Speaker 2: state where we're so well adapted to adjusting to changes 956 00:50:54,120 --> 00:50:57,319 Speaker 2: in the natural world, and all of those things that 957 00:50:57,360 --> 00:51:00,920 Speaker 2: have developed over the millennia really don't help us in 958 00:51:00,920 --> 00:51:04,960 Speaker 2: the modern world. If anything, it's probably certainly in investing. 959 00:51:05,000 --> 00:51:06,640 Speaker 2: It seems to be pretty problematic. 960 00:51:07,000 --> 00:51:10,000 Speaker 1: Yeah, exactly. In fact, that's called the evolutionary mismatch hypothesis. 961 00:51:10,120 --> 00:51:11,960 Speaker 2: Oh really, I didn't know it had a name. 962 00:51:12,040 --> 00:51:15,200 Speaker 3: Yes, exactly, So tell us about it, called the Ritholts 963 00:51:16,520 --> 00:51:21,480 Speaker 3: if only so, this mismatch is simply we evolve to 964 00:51:21,560 --> 00:51:24,240 Speaker 3: adapt on the savannah, and that doesn't help us figure 965 00:51:24,280 --> 00:51:25,359 Speaker 3: out which bonds to buy. 966 00:51:25,440 --> 00:51:26,200 Speaker 2: Is it that simple? 967 00:51:26,360 --> 00:51:30,120 Speaker 1: Exactly exactly. So another way to think of it is 968 00:51:30,120 --> 00:51:34,319 Speaker 1: is institutions. Sometimes it's families, it's political advertisement. It might 969 00:51:34,360 --> 00:51:38,600 Speaker 1: be fine print about fees in a you know, in 970 00:51:38,680 --> 00:51:42,120 Speaker 1: a financial advertisement. Those are all things that are kind 971 00:51:42,120 --> 00:51:47,759 Speaker 1: of tricking or exploiting vulnerabilities in our basic ancestral biology. 972 00:51:48,080 --> 00:51:51,000 Speaker 1: Now again, people are smart too, so there's there is 973 00:51:51,080 --> 00:51:54,759 Speaker 1: adaptation and kind of plasticity. So over a lifetime you 974 00:51:54,840 --> 00:51:59,560 Speaker 1: might or maybe in one mba course or even possibly 975 00:51:59,560 --> 00:52:02,680 Speaker 1: a high schoo of course, you might learn some principles 976 00:52:02,680 --> 00:52:05,480 Speaker 1: of basic finance that really help you avoid dumb mistakes. 977 00:52:05,600 --> 00:52:08,640 Speaker 1: You know, like compound interest really compounds quickly. You know, 978 00:52:09,160 --> 00:52:13,600 Speaker 1: the Caveman brain thinks compounding quickly. I have no idea 979 00:52:13,640 --> 00:52:16,640 Speaker 1: what that means. My brain can't imagine if I invested 980 00:52:16,640 --> 00:52:19,040 Speaker 1: in the S and P one thousand dollars forty years ago, 981 00:52:19,120 --> 00:52:21,440 Speaker 1: how much i'd have. You know, I can't compute that number. 982 00:52:21,920 --> 00:52:24,880 Speaker 2: Well, we live in an arithmetic world. Exponential numbers, they 983 00:52:24,880 --> 00:52:26,200 Speaker 2: are hard to comprehend. 984 00:52:26,560 --> 00:52:30,279 Speaker 1: The brain is mostly linearizing things that and if they're 985 00:52:30,280 --> 00:52:36,280 Speaker 1: not linear, or they're dramatically nonlinear, like pandemic compound interest, 986 00:52:36,800 --> 00:52:38,560 Speaker 1: we can learn to overcome it. But we need these 987 00:52:38,600 --> 00:52:41,759 Speaker 1: kind of external tools. It's almost like exoskeleton, you know, 988 00:52:41,760 --> 00:52:44,200 Speaker 1: whether it's education advisors and so on. 989 00:52:44,600 --> 00:52:47,680 Speaker 2: So let's talk a little bit about risk aversion, which 990 00:52:47,719 --> 00:52:54,320 Speaker 2: has been this behavioral finance concept. People dislike losses twice 991 00:52:54,320 --> 00:52:58,480 Speaker 2: as much as they enjoy gains. What does a world 992 00:52:58,560 --> 00:53:02,040 Speaker 2: of neuroeconomics say about loss of version. I've seen a 993 00:53:02,040 --> 00:53:08,680 Speaker 2: few mathematicians claim, oh, it's just a statistical anomaly. I 994 00:53:08,760 --> 00:53:10,760 Speaker 2: remain unconvinced that that's the case. 995 00:53:11,320 --> 00:53:13,480 Speaker 1: Yeah, so, actually I know a lot about loss of persion. 996 00:53:13,520 --> 00:53:16,879 Speaker 1: We published a meta analysis last year about. 997 00:53:16,680 --> 00:53:19,040 Speaker 2: There's a reason I'm asking this question. It's not out 998 00:53:19,040 --> 00:53:19,920 Speaker 2: of left field. 999 00:53:19,760 --> 00:53:23,319 Speaker 1: Right, you came to the right place. So in the 1000 00:53:23,320 --> 00:53:25,719 Speaker 1: men analysis, we looked at hundreds of studies, basically every 1001 00:53:25,760 --> 00:53:29,520 Speaker 1: study we could find, you know, using informatics, and nowadays 1002 00:53:29,560 --> 00:53:32,360 Speaker 1: you can really do this. It's like a industrial fishing, 1003 00:53:32,400 --> 00:53:34,080 Speaker 1: you know, you throw this net out and you get 1004 00:53:34,320 --> 00:53:36,279 Speaker 1: four thousand studies. Then you win to it down to the 1005 00:53:36,280 --> 00:53:38,799 Speaker 1: ones that are really just all trying to measure the 1006 00:53:38,840 --> 00:53:41,040 Speaker 1: same thing, so you can add them up. There was 1007 00:53:41,080 --> 00:53:44,759 Speaker 1: something like three hundred and seventy estimates of lambda, which 1008 00:53:44,800 --> 00:53:46,640 Speaker 1: is the Greek symbol that means the ratio of the 1009 00:53:46,680 --> 00:53:50,319 Speaker 1: disutility of loss to gain. And as you mentioned, two 1010 00:53:50,440 --> 00:53:52,080 Speaker 1: is sort of a we think it's a little bit 1011 00:53:52,080 --> 00:53:55,920 Speaker 1: smaller like one point sabin, but you know it's comparable. Yeah, 1012 00:53:55,960 --> 00:53:58,640 Speaker 1: it's comparable, and it's not one, which which would be 1013 00:53:58,680 --> 00:54:00,719 Speaker 1: the case in which you're not just finguishing loss and 1014 00:54:00,760 --> 00:54:04,800 Speaker 1: gain at all. You know, they're just like one scale. 1015 00:54:05,239 --> 00:54:08,640 Speaker 1: So the evidence is pretty good. Some other fun facts 1016 00:54:08,640 --> 00:54:10,960 Speaker 1: about loss of version, which is you might think that 1017 00:54:11,040 --> 00:54:14,840 Speaker 1: loss of version is is some kind of handicap, but 1018 00:54:14,960 --> 00:54:18,279 Speaker 1: actually we published a paper with two people who have 1019 00:54:18,360 --> 00:54:22,400 Speaker 1: brain damage and bilateral amigdala, which means neither part of 1020 00:54:22,440 --> 00:54:25,360 Speaker 1: the amgdala can compensate for the other. There's a very 1021 00:54:25,440 --> 00:54:27,759 Speaker 1: unusual disease. It comes from a or a bag via 1022 00:54:27,880 --> 00:54:30,600 Speaker 1: the disease, and they basically the amigdala is kind of 1023 00:54:30,640 --> 00:54:34,920 Speaker 1: like calcified, so it's it's there, but it's like deep freeze, 1024 00:54:34,960 --> 00:54:36,000 Speaker 1: you know, just so work. 1025 00:54:36,520 --> 00:54:40,920 Speaker 2: These people lose the ability to have these emotional responses 1026 00:54:41,080 --> 00:54:42,480 Speaker 2: to stimulus. 1027 00:54:41,840 --> 00:54:45,520 Speaker 1: Correct correct, and a lot has been known about because 1028 00:54:45,520 --> 00:54:48,400 Speaker 1: they've been studied. One of my colleagues, Ralphedelps, has studied 1029 00:54:48,880 --> 00:54:50,920 Speaker 1: several of them for years and they you know, they 1030 00:54:50,920 --> 00:54:52,680 Speaker 1: come back every so often and do a different. 1031 00:54:52,520 --> 00:54:55,520 Speaker 2: Kind of task and let me guess, they're pretty good traders. 1032 00:54:55,880 --> 00:54:59,680 Speaker 1: Generally, they're in disability because, uh, the amygdala damage is 1033 00:54:59,800 --> 00:55:02,839 Speaker 1: not to make they basically take too much risk in 1034 00:55:02,920 --> 00:55:04,160 Speaker 1: a lot of areas of life. 1035 00:55:05,360 --> 00:55:07,960 Speaker 2: So they're risk embracing, not risk averse at all. 1036 00:55:08,040 --> 00:55:11,480 Speaker 1: So the idea that that risk and fear are there 1037 00:55:11,560 --> 00:55:15,000 Speaker 1: to kind of protect you applies to them. Like when 1038 00:55:15,000 --> 00:55:17,719 Speaker 1: you remove that, like one of the patients, Sam makes 1039 00:55:17,719 --> 00:55:18,800 Speaker 1: a lot of poor choices. 1040 00:55:19,920 --> 00:55:20,840 Speaker 2: Give us examples. 1041 00:55:21,120 --> 00:55:23,520 Speaker 1: Well, this example I recall, I hope I'm not getting that. 1042 00:55:23,880 --> 00:55:26,680 Speaker 1: My memory is not mangling it too badly? Is She 1043 00:55:26,840 --> 00:55:29,600 Speaker 1: went on some kind of a date and the person 1044 00:55:29,719 --> 00:55:33,440 Speaker 1: was very sexually aggressive, and she ended up okay, And 1045 00:55:33,520 --> 00:55:35,160 Speaker 1: then somebody said, well, would you want to go out 1046 00:55:35,160 --> 00:55:37,000 Speaker 1: with that person again? She said, yeah, yeah, it was fine, 1047 00:55:37,120 --> 00:55:40,160 Speaker 1: it was fun. You know, she just didn't have this trauma. 1048 00:55:40,880 --> 00:55:44,000 Speaker 1: The amial was not processing. This is really bad. Run away, 1049 00:55:44,200 --> 00:55:45,600 Speaker 1: run away, avoid avoid. 1050 00:55:46,040 --> 00:55:51,200 Speaker 2: So how does this manifest itself amongst investors making risk 1051 00:55:51,520 --> 00:55:58,640 Speaker 2: decisions If their ability to process threats process fear is 1052 00:55:58,719 --> 00:56:01,360 Speaker 2: in present, what happens with those sort of decisions. 1053 00:56:01,440 --> 00:56:04,160 Speaker 1: Well, so for these two patients with imigal damage, they 1054 00:56:04,200 --> 00:56:05,320 Speaker 1: have no loss of version. 1055 00:56:05,520 --> 00:56:10,160 Speaker 2: None whatsoever, And so aggressive traders and investors, Well, so. 1056 00:56:10,520 --> 00:56:12,279 Speaker 1: Yeah, so the way we measures we give them these 1057 00:56:12,360 --> 00:56:15,359 Speaker 1: financial simple financial risks, like you could win. Most people 1058 00:56:15,400 --> 00:56:18,000 Speaker 1: if you say you could win ten, but you might 1059 00:56:18,120 --> 00:56:20,320 Speaker 1: lose eight or might lose seven, they're kind of just 1060 00:56:20,440 --> 00:56:23,080 Speaker 1: indifferent because a loss of seven and a gainer ten. 1061 00:56:23,040 --> 00:56:24,440 Speaker 2: Or you know, if I could, if I could do 1062 00:56:24,600 --> 00:56:27,200 Speaker 2: that on a billion dollars, I would, you know, I'd 1063 00:56:27,239 --> 00:56:27,759 Speaker 2: love to do that. 1064 00:56:28,480 --> 00:56:32,719 Speaker 1: But these two so damage the amgala. No more loss 1065 00:56:32,719 --> 00:56:36,560 Speaker 1: of version. So that's partly a reminder that be careful 1066 00:56:36,560 --> 00:56:39,239 Speaker 1: what you wish for, right, right, Like you. 1067 00:56:39,239 --> 00:56:42,640 Speaker 2: Don't want to react emotionally to everything correct right. The 1068 00:56:43,080 --> 00:56:45,719 Speaker 2: reason it's so hard to do, what Warren Buffett says, 1069 00:56:46,320 --> 00:56:49,520 Speaker 2: is when everybody's clamoring to buy, you get most people 1070 00:56:49,640 --> 00:56:54,120 Speaker 2: get caught up in that enthusiasm where we're social primates, 1071 00:56:54,160 --> 00:56:57,759 Speaker 2: and when the group is screaming bye bye bye, it's 1072 00:56:57,920 --> 00:57:00,359 Speaker 2: very hard to go with the other direction. And then 1073 00:57:00,640 --> 00:57:04,160 Speaker 2: at the bottom, when everybody is selling, the fear is 1074 00:57:04,239 --> 00:57:05,240 Speaker 2: of the alcohols. 1075 00:57:05,640 --> 00:57:09,600 Speaker 1: The fear of school was contagious very much. So right, yeah, yeah, yeah. 1076 00:57:09,760 --> 00:57:13,440 Speaker 2: So you lose that risk aversion. Do you have the 1077 00:57:13,560 --> 00:57:17,400 Speaker 2: ability to just go opposite the crowd because you don't care? 1078 00:57:17,880 --> 00:57:21,400 Speaker 1: It could be I mean, I've I have a feeling 1079 00:57:21,760 --> 00:57:25,880 Speaker 1: successful traders is it's not that they're not loss of verse, 1080 00:57:25,920 --> 00:57:29,720 Speaker 1: but they managed to inhibit it somehow. Or we did 1081 00:57:29,760 --> 00:57:31,600 Speaker 1: a such study in this but it's I don't think 1082 00:57:31,640 --> 00:57:34,200 Speaker 1: the details are all interesting for your readers, but or 1083 00:57:34,240 --> 00:57:36,440 Speaker 1: they're able to do what we call bracketing or kind 1084 00:57:36,480 --> 00:57:39,800 Speaker 1: of portfolio view, which is to say, you have bad 1085 00:57:39,880 --> 00:57:41,680 Speaker 1: days and good days and at the end it's my 1086 00:57:41,840 --> 00:57:43,840 Speaker 1: you know, it's my p and L at the end 1087 00:57:43,880 --> 00:57:45,200 Speaker 1: of the month or at the end of the year 1088 00:57:45,280 --> 00:57:48,160 Speaker 1: or the other quarter, and managed to kind of shrug 1089 00:57:48,240 --> 00:57:51,520 Speaker 1: off a loss. Now, I don't think that's that easy 1090 00:57:51,600 --> 00:57:54,800 Speaker 1: to do if you have intact amygdala right right, So 1091 00:57:54,880 --> 00:57:58,040 Speaker 1: it's it's almost it. It leads into another interesting topic 1092 00:57:58,040 --> 00:58:01,120 Speaker 1: which we've studied a little bit called emotion regular which 1093 00:58:01,200 --> 00:58:03,240 Speaker 1: is the fact that a lot of our emotions are 1094 00:58:03,240 --> 00:58:05,920 Speaker 1: sort of involuntary. You know, if there's a loud boom, 1095 00:58:06,000 --> 00:58:08,400 Speaker 1: you and I are both going to have this fear reaction. 1096 00:58:08,560 --> 00:58:12,320 Speaker 1: You know, haro, stand up will freeze. But you can 1097 00:58:12,360 --> 00:58:15,400 Speaker 1: also learn to regulate emotions. I mean kids are learning 1098 00:58:15,480 --> 00:58:18,400 Speaker 1: that when they learn to, you know, not be too 1099 00:58:18,440 --> 00:58:21,560 Speaker 1: afraid on the first day of school. As people get older, 1100 00:58:21,600 --> 00:58:25,720 Speaker 1: they learn to regulate emotions it's a pretty important skill. 1101 00:58:25,920 --> 00:58:29,600 Speaker 1: And so I think successful trading is probably some kind 1102 00:58:29,600 --> 00:58:33,080 Speaker 1: of cocktail of either a little less natural loss of 1103 00:58:33,160 --> 00:58:35,600 Speaker 1: version but not too little, right, because you don't want 1104 00:58:35,600 --> 00:58:38,040 Speaker 1: to like going crazy. You don't want them to be 1105 00:58:38,080 --> 00:58:40,439 Speaker 1: immune to loss, just like you don't want your hand 1106 00:58:40,520 --> 00:58:42,880 Speaker 1: to be immune to pain, right, because you're going to 1107 00:58:42,960 --> 00:58:46,800 Speaker 1: lean on a hot stoves one day and not notice 1108 00:58:46,800 --> 00:58:50,680 Speaker 1: that your hand is on fire. Right. So you a 1109 00:58:50,760 --> 00:58:53,280 Speaker 1: good trader probably has a little less natural loss of version, 1110 00:58:53,320 --> 00:58:57,200 Speaker 1: and then a really good ability to emotionally regulate, you know, 1111 00:58:57,280 --> 00:59:00,920 Speaker 1: when too much loss is acceptable or getting you into trouble. 1112 00:59:01,080 --> 00:59:06,400 Speaker 2: So the emotional regulation aspect is really interesting. I'm going 1113 00:59:06,480 --> 00:59:09,680 Speaker 2: to push you a little outside of your normal I 1114 00:59:09,800 --> 00:59:13,920 Speaker 2: think of your normal research area. One of the interesting 1115 00:59:14,160 --> 00:59:18,959 Speaker 2: comments that have come up when discussing who's a great 1116 00:59:19,240 --> 00:59:21,920 Speaker 2: fund manager, who's a great trader? Who are these folks 1117 00:59:22,240 --> 00:59:26,320 Speaker 2: that have put together these really impressive track records? A 1118 00:59:26,560 --> 00:59:29,840 Speaker 2: surprising number of neuroatypical folks. 1119 00:59:30,000 --> 00:59:30,439 Speaker 1: Oh yeah. 1120 00:59:30,760 --> 00:59:33,440 Speaker 2: The reason I asked you this is it seems like 1121 00:59:33,680 --> 00:59:35,680 Speaker 2: not only is there a little bit of ability to 1122 00:59:35,920 --> 00:59:40,080 Speaker 2: manage the emotions, but there's that ability to step outside 1123 00:59:40,080 --> 00:59:42,400 Speaker 2: of the crowd and say, I don't care what the 1124 00:59:42,480 --> 00:59:44,040 Speaker 2: rest of the primates are doing. 1125 00:59:44,680 --> 00:59:44,880 Speaker 1: Here. 1126 00:59:45,440 --> 00:59:48,880 Speaker 2: In March two thousand and nine, stocks look really attractive, 1127 00:59:48,960 --> 00:59:51,200 Speaker 2: and I want to be a buyer even though everybody 1128 00:59:51,200 --> 00:59:54,200 Speaker 2: else is selling. Is there an aspect of that to 1129 00:59:54,440 --> 00:59:55,520 Speaker 2: those sorts of ya. 1130 00:59:56,000 --> 00:59:58,480 Speaker 1: That's a fantastic topic. In fact, it is close to something. 1131 00:59:58,680 --> 01:00:00,720 Speaker 2: Oh, it is all right, good, I've been thinking about. 1132 01:00:00,760 --> 01:00:04,040 Speaker 1: So one thing is I was going to mention from before. 1133 01:00:04,160 --> 01:00:06,600 Speaker 1: So one of the striking things. I was working on 1134 01:00:06,680 --> 01:00:09,640 Speaker 1: an economics book and I was reading a lot of 1135 01:00:09,680 --> 01:00:13,520 Speaker 1: papers on social conformity. It turns out that almost every 1136 01:00:13,680 --> 01:00:18,240 Speaker 1: study finds the typical paradigm is something very stylized and simple, like, 1137 01:00:18,920 --> 01:00:21,680 Speaker 1: you know, you see a face and three other people 1138 01:00:21,760 --> 01:00:23,600 Speaker 1: see the same face, and you're asked to say is 1139 01:00:23,640 --> 01:00:26,880 Speaker 1: this person friendly or unfriendly? And in the conformity case, 1140 01:00:26,960 --> 01:00:30,200 Speaker 1: the other three people say friendly, and some other subject 1141 01:00:30,240 --> 01:00:34,480 Speaker 1: the other three see unfriendly, and people there seems to 1142 01:00:34,480 --> 01:00:37,840 Speaker 1: be a reward activity when you conform to the group. 1143 01:00:38,960 --> 01:00:42,400 Speaker 1: And these are not we're not super stress testing, so 1144 01:00:42,480 --> 01:00:45,280 Speaker 1: we're not quite something like you know, you're in the 1145 01:00:45,680 --> 01:00:48,360 Speaker 1: depth of a crash two thousand and eight crash and 1146 01:00:48,520 --> 01:00:51,800 Speaker 1: everyone's selling, and you know, ethically, it's hard for us 1147 01:00:51,840 --> 01:00:54,880 Speaker 1: to generate that dramatic an event in the lab. But 1148 01:00:55,520 --> 01:00:57,800 Speaker 1: even for these mild effects, and a lot of these people, 1149 01:00:57,840 --> 01:01:00,280 Speaker 1: if you ask them, do you follow the craft, they 1150 01:01:00,280 --> 01:01:01,520 Speaker 1: would say no, no, no, I kind of go in 1151 01:01:01,560 --> 01:01:03,040 Speaker 1: my own way. Like if a bunch of people said 1152 01:01:03,080 --> 01:01:05,640 Speaker 1: someone is friendly and you weren't sure, if you thought 1153 01:01:05,640 --> 01:01:07,720 Speaker 1: they weren't friendly, would you disagree? H Yeah, yeah, I 1154 01:01:07,880 --> 01:01:10,880 Speaker 1: wouldn't bother me. But study after study, the study shows 1155 01:01:10,960 --> 01:01:15,400 Speaker 1: there's generally reward value from conformity, which is essentially just 1156 01:01:15,480 --> 01:01:18,760 Speaker 1: the modern evidence for what you were talking about, which 1157 01:01:18,800 --> 01:01:20,560 Speaker 1: is that part of being a social animal right. 1158 01:01:20,680 --> 01:01:25,920 Speaker 2: The evolution of cooperation has has been very successful for us. Exactly, 1159 01:01:26,080 --> 01:01:27,680 Speaker 2: it started to fight the craft, It. 1160 01:01:27,720 --> 01:01:30,120 Speaker 1: Did his job, Yeah, exactly. Huh So I thought that 1161 01:01:30,200 --> 01:01:32,120 Speaker 1: was quite striking. Again, if you were if you wanted 1162 01:01:32,160 --> 01:01:36,160 Speaker 1: to study anti authoritarian personality, it might be a way 1163 01:01:36,200 --> 01:01:39,200 Speaker 1: to get into that that there be people who almost pathologically. 1164 01:01:39,480 --> 01:01:43,360 Speaker 1: But let's get back to your point about neurotypical people. 1165 01:01:43,520 --> 01:01:47,800 Speaker 1: So we're actually working at it beginning that a study 1166 01:01:47,840 --> 01:01:50,840 Speaker 1: on autism, so it's autism is called a spectrum disorder, 1167 01:01:50,880 --> 01:01:52,560 Speaker 1: which basically means it's not like you have it or 1168 01:01:52,600 --> 01:01:56,320 Speaker 1: you don't like schizophrenia. So you know, statistically it's it 1169 01:01:56,400 --> 01:01:57,600 Speaker 1: doesn't look like two humps. 1170 01:01:57,760 --> 01:01:59,320 Speaker 2: So you have a little, you could have some, you 1171 01:01:59,360 --> 01:02:00,600 Speaker 2: could have more, you can have a lot. 1172 01:02:00,800 --> 01:02:03,960 Speaker 1: Correct, correct, And there's often differences of symptoms like extreme 1173 01:02:04,000 --> 01:02:08,320 Speaker 1: autism often involves catatonia and severe language deficits and what 1174 01:02:08,440 --> 01:02:12,720 Speaker 1: have you. And so what people often think about Asperger syndrome, 1175 01:02:12,760 --> 01:02:15,280 Speaker 1: which is something that's called high functioning autism, right, which 1176 01:02:15,320 --> 01:02:18,200 Speaker 1: is basically you just just socially awkward and hard to 1177 01:02:18,320 --> 01:02:23,360 Speaker 1: understand what people do. But a lot of these pathologies 1178 01:02:24,000 --> 01:02:26,560 Speaker 1: or disorders, I should say pathology is not the right word. 1179 01:02:27,040 --> 01:02:29,640 Speaker 1: A lot of these disorders are accompanied by some enhancement. 1180 01:02:30,840 --> 01:02:34,400 Speaker 1: So for example, Asperger's patients have are more, they could 1181 01:02:34,440 --> 01:02:37,400 Speaker 1: have perfect pitch for a sound. They are better at 1182 01:02:37,440 --> 01:02:41,600 Speaker 1: ignoring some costs, which is a classic Bayer economics. You know, 1183 01:02:41,920 --> 01:02:43,920 Speaker 1: I spend so much on this dessert. You know, I 1184 01:02:44,000 --> 01:02:47,280 Speaker 1: came to New York. It is eighteen dollars for some flower. 1185 01:02:47,520 --> 01:02:51,160 Speaker 1: You know, I have to finish it, right. 1186 01:02:51,440 --> 01:02:53,440 Speaker 2: The autism, the money is spent whether you get the 1187 01:02:53,520 --> 01:02:54,200 Speaker 2: categories or not. 1188 01:02:54,320 --> 01:02:57,320 Speaker 1: So the autists have the right idea and. 1189 01:02:57,360 --> 01:02:59,280 Speaker 2: There is a sweet spot. I'm going to get you 1190 01:02:59,400 --> 01:03:03,080 Speaker 2: a list of the people who I know in this 1191 01:03:03,320 --> 01:03:08,000 Speaker 2: field who have that fantastic impressive numbers and have either 1192 01:03:08,760 --> 01:03:13,320 Speaker 2: stated there on the spectrum or it's kind of obvious hey. 1193 01:03:14,040 --> 01:03:16,840 Speaker 1: Yeah, yeah, yeah. You could look at film, video or 1194 01:03:17,080 --> 01:03:20,800 Speaker 1: written statements and you know, machine learned them and say, 1195 01:03:21,040 --> 01:03:22,440 Speaker 1: this person talks or looks. 1196 01:03:22,840 --> 01:03:27,000 Speaker 2: I'll ask on Twitter who's on the autism spectrum in 1197 01:03:27,040 --> 01:03:29,560 Speaker 2: the world of finance and has a good track record. 1198 01:03:29,640 --> 01:03:31,800 Speaker 2: But I have like two dozen names in my head. 1199 01:03:31,880 --> 01:03:34,560 Speaker 1: I'll give you a name. Unfortunately, he just died not 1200 01:03:34,640 --> 01:03:36,920 Speaker 1: too long ago, Charlie Munger. So of course Charlie a 1201 01:03:36,960 --> 01:03:38,160 Speaker 1: few times, right. 1202 01:03:38,240 --> 01:03:42,120 Speaker 2: And he doesn't strike me as very spectrumy. 1203 01:03:42,360 --> 01:03:45,520 Speaker 1: Well, but what one marker of autism is is like 1204 01:03:46,200 --> 01:03:49,920 Speaker 1: poor conversational turn taking, you know. And so when the 1205 01:03:50,000 --> 01:03:52,200 Speaker 1: times I met Charlie just twice and if you see 1206 01:03:52,240 --> 01:03:55,040 Speaker 1: him at the Berkshire Hathaway, I mean, he's amazing. I 1207 01:03:55,120 --> 01:03:57,520 Speaker 1: think it was like the Mark Twain of finance for sure, 1208 01:03:57,680 --> 01:04:00,640 Speaker 1: you know, because he was really witty and but also 1209 01:04:00,720 --> 01:04:04,040 Speaker 1: there's always like a really deep psychological insight in there. 1210 01:04:04,240 --> 01:04:06,240 Speaker 1: You know, it wasn't just funny. It was funny and 1211 01:04:06,320 --> 01:04:09,080 Speaker 1: true and often something other people didn't want to say. 1212 01:04:09,880 --> 01:04:12,200 Speaker 1: But when I met him, he was just like a 1213 01:04:12,280 --> 01:04:15,520 Speaker 1: freight train, and so you had to interrupt, and I 1214 01:04:15,640 --> 01:04:18,800 Speaker 1: realized the goal is to not have a conversation. You're 1215 01:04:18,840 --> 01:04:19,960 Speaker 1: just going to move the train. 1216 01:04:19,800 --> 01:04:22,080 Speaker 2: And different, just nudge him in different. Right. 1217 01:04:22,720 --> 01:04:24,360 Speaker 1: Well, you know that reminds me of X boom, and 1218 01:04:24,400 --> 01:04:25,760 Speaker 1: then he's often discussing X. 1219 01:04:26,000 --> 01:04:27,760 Speaker 2: I never realized that about him. 1220 01:04:27,800 --> 01:04:30,560 Speaker 1: So you're saying, that's my non clinical I am not 1221 01:04:30,640 --> 01:04:33,440 Speaker 1: a transition, but you know, disclaimer. Part of it is 1222 01:04:33,520 --> 01:04:36,000 Speaker 1: reflected and why he was successful. You know, he he 1223 01:04:36,080 --> 01:04:38,880 Speaker 1: saw himself as an average person who wasn't making the 1224 01:04:38,960 --> 01:04:41,800 Speaker 1: dumb mistakes other people make. But some of those dumb 1225 01:04:41,800 --> 01:04:44,040 Speaker 1: mistake people make, you know, he may have not made 1226 01:04:44,080 --> 01:04:46,800 Speaker 1: them because he doesn't get caught up in social conformity, 1227 01:04:47,280 --> 01:04:49,919 Speaker 1: or because he's very focused on he has good metacognition, 1228 01:04:50,160 --> 01:04:51,880 Speaker 1: like if I don't I don't buy a company I 1229 01:04:51,920 --> 01:04:56,400 Speaker 1: don't understand, right, you know, that's probably a good strategy. 1230 01:04:56,720 --> 01:04:59,520 Speaker 2: So I'm working on a new book. I'm almost done, 1231 01:04:59,600 --> 01:05:02,960 Speaker 2: and Munger is great. One of the two people I 1232 01:05:03,080 --> 01:05:06,360 Speaker 2: dedicate the book to and the quote of his that 1233 01:05:07,040 --> 01:05:11,040 Speaker 2: very much informs the the theme of the book is 1234 01:05:11,160 --> 01:05:15,080 Speaker 2: someone once asked him was Berkshire successful because Ewan and 1235 01:05:15,200 --> 01:05:17,840 Speaker 2: Warren are so much smarter than everybody else? And his 1236 01:05:18,000 --> 01:05:20,760 Speaker 2: response was, it's not that we're smarter than everybody else, 1237 01:05:21,200 --> 01:05:27,040 Speaker 2: we were just less stupid, which is such an insightful observation. Hey, 1238 01:05:27,320 --> 01:05:31,919 Speaker 2: just fewer Charlie Ellis, make less unforced errors, and you'll 1239 01:05:32,320 --> 01:05:35,800 Speaker 2: do better in tennis or investing than the guy trying 1240 01:05:35,840 --> 01:05:38,000 Speaker 2: to slam the ace, and most people are not going 1241 01:05:38,040 --> 01:05:40,880 Speaker 2: to get it in. Him and Munger had the two 1242 01:05:41,000 --> 01:05:44,920 Speaker 2: Charlie's had the same belief system, just be less stupid. 1243 01:05:45,240 --> 01:05:50,360 Speaker 2: It's really fascinating. So when you've interviewed Munger, what are 1244 01:05:50,400 --> 01:05:53,680 Speaker 2: some of the takeaways you've had from your conversations with him? 1245 01:05:55,200 --> 01:05:57,280 Speaker 1: One thing I remember was for so we went and 1246 01:05:57,360 --> 01:05:59,280 Speaker 1: looked at our neuroimaging center. 1247 01:06:00,040 --> 01:06:01,880 Speaker 2: Did you ever get him in a machine? No? 1248 01:06:02,720 --> 01:06:05,080 Speaker 1: I wish. I wish we had. He he may have 1249 01:06:05,120 --> 01:06:06,680 Speaker 1: gone for it too. He's you know, he's a pretty 1250 01:06:06,760 --> 01:06:12,320 Speaker 1: interesting person and I think very open minds, scientifically curious 1251 01:06:12,480 --> 01:06:16,680 Speaker 1: as well as in his financial life. He had gone 1252 01:06:16,720 --> 01:06:19,000 Speaker 1: to Celtic for a while. So he was we got 1253 01:06:19,040 --> 01:06:20,880 Speaker 1: to run into every so often. Of course, we're always 1254 01:06:20,960 --> 01:06:22,400 Speaker 1: people like that. They're always trying to get him to 1255 01:06:22,400 --> 01:06:24,400 Speaker 1: give money and or at least show. 1256 01:06:24,280 --> 01:06:26,440 Speaker 2: Up and give a speech something. 1257 01:06:26,680 --> 01:06:30,240 Speaker 1: Yeah, talk, and so so we showed in the brain scanner. 1258 01:06:30,520 --> 01:06:32,440 Speaker 1: He had a really interesting thought which I didn't quite 1259 01:06:32,440 --> 01:06:37,760 Speaker 1: appreciate till later, which was he said, what you guys 1260 01:06:37,760 --> 01:06:40,480 Speaker 1: should be doing is if you're trying to change behavior, 1261 01:06:40,560 --> 01:06:42,680 Speaker 1: like let's say you're trying to get somebody to vote, 1262 01:06:43,000 --> 01:06:46,520 Speaker 1: or to wear a mask or you know, quit smoking. 1263 01:06:46,600 --> 01:06:47,960 Speaker 1: Opioid's the really hard stuff. 1264 01:06:48,000 --> 01:06:48,120 Speaker 2: You know. 1265 01:06:48,200 --> 01:06:50,480 Speaker 1: Wait, unless he said, what you should really do is, 1266 01:06:50,600 --> 01:06:53,400 Speaker 1: rather than doing one little thing, you should go for 1267 01:06:53,480 --> 01:06:56,320 Speaker 1: a lollapalooza, you know, like basically try to add in 1268 01:06:56,480 --> 01:07:00,280 Speaker 1: six different things to get the biggest ability to get 1269 01:07:00,280 --> 01:07:01,120 Speaker 1: people to quit smoking. 1270 01:07:01,240 --> 01:07:02,080 Speaker 2: Let's say it makes sense. 1271 01:07:02,480 --> 01:07:04,440 Speaker 1: And so he was thinking as a practitioner like I 1272 01:07:04,560 --> 01:07:07,320 Speaker 1: want I'm going to know what's going to work, as 1273 01:07:07,400 --> 01:07:10,800 Speaker 1: scientists were often thinking piecemeal, like if we put six 1274 01:07:10,880 --> 01:07:13,480 Speaker 1: different things in and it works, we don't know which 1275 01:07:13,520 --> 01:07:16,040 Speaker 1: of the six is the active ingredient, but it. 1276 01:07:16,080 --> 01:07:18,960 Speaker 2: Could be a different combination for each different exactly. 1277 01:07:18,680 --> 01:07:21,560 Speaker 1: So exactly, but and so the reason I was thinking 1278 01:07:21,600 --> 01:07:24,440 Speaker 1: about that was nowadays, one of the fallouts or one 1279 01:07:24,480 --> 01:07:26,920 Speaker 1: of the products I should say, from Fallow it's definitely 1280 01:07:26,920 --> 01:07:29,520 Speaker 1: the wrong word. One of the products from Beata economics 1281 01:07:29,680 --> 01:07:32,680 Speaker 1: was this idea of a nudge that often because people 1282 01:07:32,680 --> 01:07:35,200 Speaker 1: are often sensitive to very subtle things like opt in 1283 01:07:35,360 --> 01:07:38,080 Speaker 1: versus opt out, you know there may be a low cost, 1284 01:07:38,640 --> 01:07:41,280 Speaker 1: light touchway to change behavior a little bit. 1285 01:07:41,840 --> 01:07:44,520 Speaker 2: Well just look at the four oh one k exactly, 1286 01:07:44,600 --> 01:07:51,720 Speaker 2: making the default go to just some specific investment as 1287 01:07:51,800 --> 01:07:56,120 Speaker 2: opposed to it just sits there in cash for god 1288 01:07:56,280 --> 01:07:59,400 Speaker 2: knows how long. Seems to have really had a big impa. 1289 01:07:59,320 --> 01:08:03,080 Speaker 1: Yes, exactly that that was definitely the poster child for 1290 01:08:03,240 --> 01:08:06,000 Speaker 1: the simplest nudge, and we kind of understand the psychology 1291 01:08:06,080 --> 01:08:08,320 Speaker 1: of it anyway. So now what a lot of people 1292 01:08:08,360 --> 01:08:11,040 Speaker 1: are thinking about nudge. This is exactly this lollapaloosa idea 1293 01:08:11,080 --> 01:08:14,000 Speaker 1: of Munger's, which is, if we want to get people 1294 01:08:14,040 --> 01:08:17,120 Speaker 1: to get out the vote, rather than try six different things, 1295 01:08:17,640 --> 01:08:22,000 Speaker 1: we should be trying like six combinations of three things. Statistically, 1296 01:08:22,080 --> 01:08:25,559 Speaker 1: it's messy because you'll never really end up knowing which 1297 01:08:25,600 --> 01:08:28,960 Speaker 1: of those is the active ingredient. But to just get results, 1298 01:08:29,439 --> 01:08:34,000 Speaker 1: that's useful information, it's useful formation. So the Nudge Enterprise, 1299 01:08:34,080 --> 01:08:36,240 Speaker 1: which I've been connected to a little bit, is moving 1300 01:08:36,320 --> 01:08:38,720 Speaker 1: somewhe in that direction that Munger mentioned many years ago. 1301 01:08:39,000 --> 01:08:41,880 Speaker 2: Huh. Really interesting? All right, I only have you for 1302 01:08:41,920 --> 01:08:44,280 Speaker 2: a limited amount of time, so let me jump to 1303 01:08:44,400 --> 01:08:47,479 Speaker 2: my favorite questions that I ask all of my guests, 1304 01:08:48,320 --> 01:08:51,760 Speaker 2: starting with what are you watching or listening to these days? 1305 01:08:51,840 --> 01:08:53,720 Speaker 2: What's keeping you entertained? 1306 01:08:54,320 --> 01:08:58,120 Speaker 1: So Katie Molkman's podcast Choiceology is one that I've been 1307 01:08:58,160 --> 01:08:59,920 Speaker 1: on that I think is quite good. It's basically the 1308 01:09:00,280 --> 01:09:03,880 Speaker 1: beaval economics podcasts. There are quite a few others, but 1309 01:09:03,960 --> 01:09:05,960 Speaker 1: Katie is a real expert on this and is a 1310 01:09:06,040 --> 01:09:07,280 Speaker 1: great interviewer and has. 1311 01:09:07,160 --> 01:09:11,519 Speaker 2: Had good guests choice Ology. Choice Ology tell us about 1312 01:09:11,640 --> 01:09:14,840 Speaker 2: your mentors who helped to shape your fascinating career. 1313 01:09:15,840 --> 01:09:18,400 Speaker 1: So two people who were on my thesis committee, Robin 1314 01:09:18,439 --> 01:09:22,519 Speaker 1: Hogarth and Hilly Einhorn were two and there's an interesting story. 1315 01:09:22,640 --> 01:09:33,360 Speaker 1: So Robin was Scottish, very verbal, every sentence started with howsoever. Therefore, notwithstanding, 1316 01:09:34,040 --> 01:09:37,400 Speaker 1: Hilly was a very blunt jew from Brooklyn, and it 1317 01:09:37,520 --> 01:09:40,400 Speaker 1: was the exact opposite so Hilly would mark up my 1318 01:09:40,560 --> 01:09:43,479 Speaker 1: thesis and put in all these fancy Hilly would rather 1319 01:09:43,520 --> 01:09:45,680 Speaker 1: would take out the whatsoevers and the howevers and that 1320 01:09:45,760 --> 01:09:48,679 Speaker 1: thereforece and he was like put in more like boom, 1321 01:09:49,080 --> 01:09:52,160 Speaker 1: like short sentences, no sema colons, but like he had 1322 01:09:52,240 --> 01:09:54,760 Speaker 1: one punctuation mark period. That's it right, Like you know, 1323 01:09:54,840 --> 01:09:57,400 Speaker 1: he like about a million periods at a store, and 1324 01:09:57,520 --> 01:09:59,840 Speaker 1: like I'm not likely to use those. And Robin was 1325 01:09:59,880 --> 01:10:02,160 Speaker 1: the way around, Oh, this really need to do summa colon, 1326 01:10:02,240 --> 01:10:04,519 Speaker 1: you know, let's plump this. And at one point I 1327 01:10:04,600 --> 01:10:06,479 Speaker 1: was going back and forth, you know, near the completion 1328 01:10:06,600 --> 01:10:09,120 Speaker 1: of my thesis with the two of them were co advisors, 1329 01:10:10,200 --> 01:10:13,000 Speaker 1: and I got so frustrated, and I said, how should 1330 01:10:13,000 --> 01:10:16,360 Speaker 1: I write this? And we had this this kind of 1331 01:10:16,479 --> 01:10:20,240 Speaker 1: like grasshopper moment of it's your thesis, you figure out 1332 01:10:20,240 --> 01:10:22,400 Speaker 1: how you want to write it. And I realized they 1333 01:10:22,400 --> 01:10:24,360 Speaker 1: were kind of waiting for me to find my voice, 1334 01:10:24,479 --> 01:10:27,559 Speaker 1: like they say in writing, you know, like and one 1335 01:10:27,600 --> 01:10:30,559 Speaker 1: of the love tables and then the other love graphs. 1336 01:10:31,040 --> 01:10:33,280 Speaker 1: So the drafts of my thesis was the table and 1337 01:10:33,320 --> 01:10:35,559 Speaker 1: a graph were exactly the same thing. And I had 1338 01:10:35,600 --> 01:10:37,679 Speaker 1: to decide was I a graph person or a table 1339 01:10:37,720 --> 01:10:40,600 Speaker 1: person or was I kind of like bilingual? So I 1340 01:10:40,680 --> 01:10:43,880 Speaker 1: basically became kind of bilingual in terms of how I 1341 01:10:43,960 --> 01:10:46,320 Speaker 1: was thinking. It's night. That was very helpful. The other 1342 01:10:46,360 --> 01:10:50,120 Speaker 1: person probably is Dick Taylor, because he he's a very 1343 01:10:50,160 --> 01:10:52,920 Speaker 1: good writer. He did exactly what so many academics aspire 1344 01:10:53,000 --> 01:10:55,840 Speaker 1: to and we always ask for more of, which is 1345 01:10:55,880 --> 01:10:59,519 Speaker 1: to write a small number of extremely high quality papers. 1346 01:11:00,080 --> 01:11:03,280 Speaker 1: It's very unusual because for career reasons and stuff, you 1347 01:11:03,360 --> 01:11:07,000 Speaker 1: have to get tenure and right, and Dick just couldn't 1348 01:11:07,000 --> 01:11:09,000 Speaker 1: really write a bad paper. I don't write as many 1349 01:11:09,640 --> 01:11:11,760 Speaker 1: great papers as him, and I as a result, I 1350 01:11:11,840 --> 01:11:14,599 Speaker 1: write too many okay papers. But that's something I think 1351 01:11:14,680 --> 01:11:15,479 Speaker 1: is useful for everyone. 1352 01:11:15,760 --> 01:11:18,479 Speaker 2: He's one of my favorite people in the world. I 1353 01:11:18,600 --> 01:11:20,719 Speaker 2: got to interview I don't know half a dozen times, 1354 01:11:21,439 --> 01:11:24,720 Speaker 2: only once since he won the Nobel Prize, but I 1355 01:11:24,840 --> 01:11:29,840 Speaker 2: always find him so informative and entertaining, and I just 1356 01:11:30,080 --> 01:11:33,400 Speaker 2: loved his response to winning the prize. What are you 1357 01:11:33,400 --> 01:11:35,600 Speaker 2: gonna do with the money? His answer is, I'm going 1358 01:11:35,680 --> 01:11:38,720 Speaker 2: to spend it as irrationally as I possibly can, just 1359 01:11:38,840 --> 01:11:42,000 Speaker 2: so so him he enjoys life. He very much does 1360 01:11:42,560 --> 01:11:47,040 Speaker 2: he's just also a fascinating, fascinating, charming guy. Let's talk 1361 01:11:47,040 --> 01:11:48,920 Speaker 2: about books. What are some of your favorites. What are 1362 01:11:48,960 --> 01:11:49,720 Speaker 2: you reading right now? 1363 01:11:50,560 --> 01:11:53,479 Speaker 1: I am reading Emma Klein a book called The Guests, 1364 01:11:54,760 --> 01:11:58,599 Speaker 1: especially for neworlcus in your audience. It's about a very grifty, 1365 01:11:58,800 --> 01:12:02,439 Speaker 1: sketchy woman who goes to the Hamptons and kind of 1366 01:12:02,560 --> 01:12:05,680 Speaker 1: cons her way around the Hamptons. It's really it's almost. 1367 01:12:05,400 --> 01:12:07,680 Speaker 2: Like a very didn't we have kind of a real 1368 01:12:07,760 --> 01:12:09,680 Speaker 2: life thing like that happening a year? 1369 01:12:09,800 --> 01:12:13,040 Speaker 1: Yes, exactly. It may be loosely inspired by Anna deel 1370 01:12:13,120 --> 01:12:17,479 Speaker 1: Vi in Manhattan or some similar cases. It's basically almost 1371 01:12:17,560 --> 01:12:21,680 Speaker 1: like a nineteenth century novel about class, because she's very 1372 01:12:21,760 --> 01:12:24,000 Speaker 1: conscious of not belonging in the Hamptons, but she's very 1373 01:12:24,040 --> 01:12:27,200 Speaker 1: beautiful and kind of charming in this sort of man 1374 01:12:27,280 --> 01:12:30,800 Speaker 1: eater femvatal way. And I'm almost done with that. It's 1375 01:12:30,840 --> 01:12:34,559 Speaker 1: really delicious. The other thing, I love movies and books 1376 01:12:34,600 --> 01:12:38,120 Speaker 1: about capers and heists and grift, which includes Emma Klein 1377 01:12:38,640 --> 01:12:41,360 Speaker 1: The Guest. So I'm reading these books by Jim Swain, 1378 01:12:41,520 --> 01:12:44,920 Speaker 1: who's not known. I got onto him. Lee Child, who 1379 01:12:45,320 --> 01:12:45,559 Speaker 1: who I. 1380 01:12:45,600 --> 01:12:48,479 Speaker 2: Love life reads all of his books plow through all 1381 01:12:48,520 --> 01:12:51,040 Speaker 2: of it exactly. Yeah, and that did that include the 1382 01:12:51,200 --> 01:12:52,080 Speaker 2: Reacher series. 1383 01:12:52,240 --> 01:12:54,280 Speaker 1: The Reacher series, that's what he is most famous for, 1384 01:12:54,439 --> 01:12:57,040 Speaker 1: the Lee Child. But so Jim Swain was blurbed by 1385 01:12:57,120 --> 01:12:59,920 Speaker 1: Lee Child, saying, Jim Swain's the best at what he does, 1386 01:13:00,040 --> 01:13:02,840 Speaker 1: and what he does is he writes about a very 1387 01:13:02,920 --> 01:13:07,880 Speaker 1: sophisticated cheater in Las Vegas who cheats casinos, and it's 1388 01:13:08,360 --> 01:13:10,519 Speaker 1: you know, I'm going to use recycle this and you're 1389 01:13:11,800 --> 01:13:16,320 Speaker 1: very shortly for you. But basically there are procedurals about 1390 01:13:16,439 --> 01:13:19,240 Speaker 1: how to cheat a casino, but in the end if 1391 01:13:19,280 --> 01:13:23,080 Speaker 1: you get caught. There's also this sort of socio psycho 1392 01:13:23,160 --> 01:13:25,960 Speaker 1: political thing of you know, if I make up a 1393 01:13:26,080 --> 01:13:28,920 Speaker 1: story about why something happened, like if there's a murder 1394 01:13:29,000 --> 01:13:31,559 Speaker 1: in a casino and I make up a story about 1395 01:13:31,600 --> 01:13:35,120 Speaker 1: it that helps them act like the murder was freakish 1396 01:13:35,160 --> 01:13:38,719 Speaker 1: and won't drive away customers. I'm actually delivering a gift 1397 01:13:38,760 --> 01:13:40,600 Speaker 1: to them, and they're going to trade off. They're not 1398 01:13:40,640 --> 01:13:42,080 Speaker 1: going to send me to jail. But if I give 1399 01:13:42,120 --> 01:13:44,040 Speaker 1: them this gift. So there's a lot of layers of 1400 01:13:44,280 --> 01:13:47,240 Speaker 1: This is not Dostoevski, It's not brilliant. This is not 1401 01:13:48,280 --> 01:13:52,000 Speaker 1: sum but for me, there's a lot of like psychology, 1402 01:13:52,080 --> 01:13:54,360 Speaker 1: and you know, in a way, it's a game theory. 1403 01:13:54,400 --> 01:13:58,280 Speaker 1: What if there's an arms race between the Vegas Gaming 1404 01:13:58,280 --> 01:14:01,920 Speaker 1: Commission and each of the individual casinos who are very sophisticated. 1405 01:14:01,960 --> 01:14:03,760 Speaker 1: They hire a lot of ex cheats, you know, to 1406 01:14:04,680 --> 01:14:07,080 Speaker 1: tell them what to look for, and then these cheaters 1407 01:14:07,120 --> 01:14:09,200 Speaker 1: who know you know, so truly, there's arms series of 1408 01:14:09,200 --> 01:14:10,920 Speaker 1: who's gonna win? I found those really interesting. 1409 01:14:11,760 --> 01:14:18,040 Speaker 2: If you like books on griffs and cheats and corruption, 1410 01:14:18,760 --> 01:14:22,240 Speaker 2: I'm gonna recommend pretty much anything he's written. I've been 1411 01:14:22,240 --> 01:14:26,160 Speaker 2: a fan of his for years. Carlhassen was a reorder 1412 01:14:26,760 --> 01:14:30,120 Speaker 2: for the Miami Herald Prime Reporter and then just one 1413 01:14:30,240 --> 01:14:34,280 Speaker 2: after another, these series of novels and his one of 1414 01:14:34,320 --> 01:14:37,040 Speaker 2: his more recent books is now a TV series on 1415 01:14:37,800 --> 01:14:42,720 Speaker 2: Apple Plus Bad Monkey, but all of his books it's 1416 01:14:42,800 --> 01:14:45,200 Speaker 2: Bad Monkey in the I think the sequel is called 1417 01:14:45,360 --> 01:14:48,360 Speaker 2: Razor Girl. But all his books take place in Florida. 1418 01:14:49,080 --> 01:14:52,559 Speaker 2: Everybody's corrupt. The police are corrupt, the building inspectors are corrupt, 1419 01:14:52,640 --> 01:14:56,000 Speaker 2: the politicians are corrupt, and there's always one or two 1420 01:14:56,080 --> 01:14:58,559 Speaker 2: good people in the heart of the story and it's 1421 01:14:58,600 --> 01:15:02,680 Speaker 2: how do they navigate? It's just endless sea of treachery 1422 01:15:02,800 --> 01:15:07,280 Speaker 2: and corruption. And he's just a delightful, entertaining writer. If 1423 01:15:07,280 --> 01:15:10,320 Speaker 2: you you could randomly pick any of his books and 1424 01:15:10,600 --> 01:15:13,040 Speaker 2: they're just all they're great beach reads. 1425 01:15:13,560 --> 01:15:15,519 Speaker 1: You know. Le Me also mentioned The Wire because I 1426 01:15:15,560 --> 01:15:20,160 Speaker 1: grew up in Baltimore County and a series. Yes, and 1427 01:15:20,520 --> 01:15:23,599 Speaker 1: David Simon's book The Corner is a kind of a precursor. 1428 01:15:23,640 --> 01:15:25,240 Speaker 1: I mean, he's a very interesting person. He was a 1429 01:15:25,320 --> 01:15:29,880 Speaker 1: reporter and I think he may have been Baltimore, Britimore. 1430 01:15:30,360 --> 01:15:33,960 Speaker 1: And The Corner is like this beautiful I think it 1431 01:15:34,040 --> 01:15:36,800 Speaker 1: was a precursor to the Wire. But it's basically about 1432 01:15:36,800 --> 01:15:39,479 Speaker 1: a corner in West Baltimore everyone buys drugs, and it's 1433 01:15:39,479 --> 01:15:41,920 Speaker 1: about drug addiction and all the things that's surrounded. So 1434 01:15:42,000 --> 01:15:44,080 Speaker 1: as somebody who you know, one of the things we 1435 01:15:44,120 --> 01:15:47,200 Speaker 1: study in behavioral economics is habits and addictions, and you know, 1436 01:15:47,320 --> 01:15:50,559 Speaker 1: and the neuroscience, of course is fascinating along the way, 1437 01:15:51,040 --> 01:15:53,320 Speaker 1: and that one is great. And The Wire having grown 1438 01:15:53,400 --> 01:15:56,040 Speaker 1: up in Baltimore County, which is not Baltimore City, The 1439 01:15:56,120 --> 01:15:58,360 Speaker 1: Wire is almost like a documentary and it has all 1440 01:15:58,400 --> 01:16:00,960 Speaker 1: this Baltimore stuff, as well as all my accents where 1441 01:16:00,960 --> 01:16:03,960 Speaker 1: you have people are talking about talking like this, and 1442 01:16:04,120 --> 01:16:07,880 Speaker 1: it has Tommy Garcetti is this political character who's sort 1443 01:16:07,880 --> 01:16:12,320 Speaker 1: of inspired by Tommy Delsandro, whose daughter is Nancy PELUSI. 1444 01:16:12,800 --> 01:16:16,639 Speaker 2: Oh really, that's amazing. I found the series the Wire. 1445 01:16:17,280 --> 01:16:21,320 Speaker 2: It's a tough watch. It's a great show. It's brutal. Yeah, 1446 01:16:21,400 --> 01:16:24,320 Speaker 2: gritty is mild. I mean some of the stuff that 1447 01:16:24,439 --> 01:16:26,120 Speaker 2: goes on, and the show is. 1448 01:16:26,280 --> 01:16:28,080 Speaker 1: Just like, yeah, there's a famous scene with the nail 1449 01:16:28,120 --> 01:16:33,320 Speaker 1: gun you're which if your listeners have the stomach, that's 1450 01:16:33,360 --> 01:16:34,080 Speaker 1: pretty classic. 1451 01:16:34,640 --> 01:16:39,240 Speaker 2: Similar in the Jack Reacher series, there's a really something 1452 01:16:39,400 --> 01:16:42,439 Speaker 2: not that far off. Yeah, they toned it down for television, 1453 01:16:42,520 --> 01:16:45,559 Speaker 2: but the book is is really brutal. All Right, we're 1454 01:16:45,640 --> 01:16:48,559 Speaker 2: up to our final two questions. What sort of advice 1455 01:16:48,640 --> 01:16:51,600 Speaker 2: would you give to a college grad interested in a 1456 01:16:51,680 --> 01:16:56,840 Speaker 2: career in filling the blank neuroeconomics, behavioral finance, or even 1457 01:16:57,120 --> 01:16:58,280 Speaker 2: just investing. 1458 01:16:58,479 --> 01:17:02,400 Speaker 1: For somebody who say it doesn't want to get a PhD. 1459 01:17:02,680 --> 01:17:05,080 Speaker 1: That's a different track and probably of less interest. And 1460 01:17:05,120 --> 01:17:07,600 Speaker 1: there's you can get a lot of guests advice on 1461 01:17:07,720 --> 01:17:10,759 Speaker 1: how to do that. I would study not just finance 1462 01:17:10,920 --> 01:17:16,720 Speaker 1: like straight asset pricing and derivatives, but also behavioral economics 1463 01:17:16,880 --> 01:17:19,320 Speaker 1: game theory, I think, because even though game theory is 1464 01:17:19,479 --> 01:17:22,600 Speaker 1: usually like two players or small numbers of players, it 1465 01:17:22,680 --> 01:17:25,720 Speaker 1: really sharpens the logic of you know, when do I 1466 01:17:25,840 --> 01:17:28,760 Speaker 1: know something another person doesn't know? And do I know 1467 01:17:28,920 --> 01:17:30,760 Speaker 1: that they don't know it? You know, you have to 1468 01:17:30,840 --> 01:17:34,000 Speaker 1: really relentlessly think about the math underlying that. And then 1469 01:17:34,000 --> 01:17:37,360 Speaker 1: there's a lot of experimental and real world data. One 1470 01:17:37,400 --> 01:17:39,920 Speaker 1: of my I just got a text from our students 1471 01:17:40,000 --> 01:17:42,439 Speaker 1: this term, and there's a lot of data from sports 1472 01:17:42,720 --> 01:17:48,080 Speaker 1: about whether sports activities are like equilibrium responses to other players, 1473 01:17:49,320 --> 01:17:51,559 Speaker 1: So you can actually there's there's a lot of sources 1474 01:17:51,560 --> 01:17:54,360 Speaker 1: of data besides just say the lab experiments. I talk 1475 01:17:54,360 --> 01:17:56,400 Speaker 1: about my book from two thousand and three, Sneaking the 1476 01:17:56,520 --> 01:17:59,960 Speaker 1: Plug in Cognitive science is something I would study too. 1477 01:18:00,280 --> 01:18:05,160 Speaker 1: So cognitive science is a modern brand of cognitive psych 1478 01:18:05,240 --> 01:18:07,360 Speaker 1: that has more math in it, and a lot of 1479 01:18:07,439 --> 01:18:10,080 Speaker 1: it actually goes back to something we spoke about, like 1480 01:18:10,680 --> 01:18:12,960 Speaker 1: a mismatch. But they are quite interested in what they 1481 01:18:13,000 --> 01:18:16,200 Speaker 1: call resource rationality, which means a lot of the mistakes 1482 01:18:16,240 --> 01:18:19,599 Speaker 1: people might make, like anchoring on one number and being 1483 01:18:19,680 --> 01:18:23,759 Speaker 1: influenced by that. A famous anchoring adjustment heuristic may actually 1484 01:18:23,840 --> 01:18:26,240 Speaker 1: be rational if you only have so much working memory, 1485 01:18:26,400 --> 01:18:29,800 Speaker 1: or you're under time pressure, or you're tired. It's also 1486 01:18:29,840 --> 01:18:33,799 Speaker 1: closely related to the way economists would think about mistakes, 1487 01:18:33,840 --> 01:18:36,280 Speaker 1: which is they may be optimal given some constraint, like 1488 01:18:36,320 --> 01:18:39,240 Speaker 1: what is that constraint and can we test that experimentally? 1489 01:18:39,840 --> 01:18:41,200 Speaker 1: So I think there's a lot of stuff you could 1490 01:18:41,280 --> 01:18:43,600 Speaker 1: learn there that will help you think about markets. The 1491 01:18:43,720 --> 01:18:48,639 Speaker 1: other thing I would say is get experience thinking about markets, 1492 01:18:48,960 --> 01:18:52,040 Speaker 1: whether in turning or I'll tell you a story about 1493 01:18:52,040 --> 01:18:53,880 Speaker 1: what worked for me, which was when I was twelve 1494 01:18:53,960 --> 01:18:59,679 Speaker 1: years old in Cockeysville, Maryland, August, there was a one 1495 01:18:59,800 --> 01:19:04,160 Speaker 1: month month racing program at a small racetrack called Timonium, Maryland, 1496 01:19:05,080 --> 01:19:06,920 Speaker 1: and it was a five eighths of a mile tracks. 1497 01:19:06,960 --> 01:19:09,680 Speaker 1: It's like a you know, small I would go with 1498 01:19:09,840 --> 01:19:12,320 Speaker 1: my dad and a friend of his who was a stockbroker, 1499 01:19:12,960 --> 01:19:14,360 Speaker 1: and we would also go to the big tracks like 1500 01:19:14,400 --> 01:19:16,840 Speaker 1: Pimlico where the preak mistakes is. But if you go 1501 01:19:16,920 --> 01:19:20,479 Speaker 1: to Timonium, you get to see all the horses. There 1502 01:19:20,560 --> 01:19:23,120 Speaker 1: was so much interest. You learned so much about markets. 1503 01:19:24,520 --> 01:19:26,120 Speaker 1: Number one. It gives you, I think, a respect for 1504 01:19:26,240 --> 01:19:27,000 Speaker 1: market efficiency. 1505 01:19:27,400 --> 01:19:30,080 Speaker 2: Couse, the odds are actually not that bad. They were 1506 01:19:30,160 --> 01:19:32,200 Speaker 2: extremely pretty pretty dead on exactly. 1507 01:19:32,240 --> 01:19:34,080 Speaker 1: And so you see, you know, eight horses come out, 1508 01:19:34,160 --> 01:19:37,479 Speaker 1: they all look pretty similar. You know, the jockeys are 1509 01:19:37,520 --> 01:19:39,960 Speaker 1: all you know, the same size, and they're all pretty good. 1510 01:19:39,960 --> 01:19:42,759 Speaker 1: There's a lot of statistics you can see. But somehow 1511 01:19:42,800 --> 01:19:47,479 Speaker 1: the crowd has decided that number three is even money favorite, 1512 01:19:47,520 --> 01:19:49,040 Speaker 1: which is a fifty e d chance to win. A 1513 01:19:49,160 --> 01:19:51,519 Speaker 1: number six, who looks pretty good too, is like seventy 1514 01:19:51,600 --> 01:19:55,760 Speaker 1: to one, and they're mostly right. So you know, part 1515 01:19:55,800 --> 01:19:58,439 Speaker 1: of why I got into economics and psychology was thinking 1516 01:19:58,479 --> 01:20:01,280 Speaker 1: about episodes like that, how does the market put this 1517 01:20:01,400 --> 01:20:06,120 Speaker 1: information together? And are the mistakes? Like how do you 1518 01:20:06,200 --> 01:20:06,800 Speaker 1: beat the market? 1519 01:20:07,000 --> 01:20:09,799 Speaker 2: So Fama turns out to be more or less right about. 1520 01:20:09,560 --> 01:20:12,200 Speaker 1: You about twenty in Maryland. And there were other interesting 1521 01:20:12,320 --> 01:20:14,560 Speaker 1: lessons too, like so on the if you go with 1522 01:20:14,640 --> 01:20:16,320 Speaker 1: like around the third race. You know, I was I 1523 01:20:16,520 --> 01:20:19,800 Speaker 1: was a kid, so I just broke and my poor mom, 1524 01:20:19,880 --> 01:20:21,680 Speaker 1: my irish mom, was worried I was going to you know, 1525 01:20:21,880 --> 01:20:25,240 Speaker 1: lose too much money. I kept telling you, it's tuition, mom, 1526 01:20:25,320 --> 01:20:30,040 Speaker 1: it's tuition. But if you go in the third race, 1527 01:20:30,080 --> 01:20:31,760 Speaker 1: there were these people who would sell tip sheets for 1528 01:20:31,880 --> 01:20:33,080 Speaker 1: like five dollars, right. 1529 01:20:33,040 --> 01:20:35,679 Speaker 2: And you know, because because they know what's going to happen, 1530 01:20:35,800 --> 01:20:38,080 Speaker 2: they're selling the tip sheets, not making the bets. 1531 01:20:37,920 --> 01:20:40,640 Speaker 1: Exactly the customer's yachts exactly. But if you go like 1532 01:20:40,720 --> 01:20:43,880 Speaker 1: in the you know, the third or fourth race, they 1533 01:20:43,880 --> 01:20:46,000 Speaker 1: would quit selling them. They would just give them to 1534 01:20:46,040 --> 01:20:49,240 Speaker 1: you really well, like a lost leader. Maybe you'll you'll 1535 01:20:49,320 --> 01:20:52,040 Speaker 1: maybe next time you'll buy it. And so I'm sitting here, 1536 01:20:52,040 --> 01:20:55,559 Speaker 1: here's my little cynical twelve thirteen year old brain thinking, 1537 01:20:56,680 --> 01:20:59,080 Speaker 1: why are you giving away for free tips that you 1538 01:20:59,240 --> 01:21:01,800 Speaker 1: claim can make me money? Like this does not the 1539 01:21:01,880 --> 01:21:05,880 Speaker 1: math does not math. And I think that's a good lesson, 1540 01:21:06,960 --> 01:21:10,280 Speaker 1: like for markets. Right yeah, but you know, just just 1541 01:21:10,360 --> 01:21:13,240 Speaker 1: to clear away like the most naive, you know, immunize 1542 01:21:13,240 --> 01:21:15,720 Speaker 1: yourself to the most naive schemes. 1543 01:21:16,120 --> 01:21:19,000 Speaker 2: You know, you would think if the tips were valuable, 1544 01:21:19,160 --> 01:21:21,439 Speaker 2: rather than waste your time printing it up and selling them, 1545 01:21:21,520 --> 01:21:25,640 Speaker 2: you would just bet on the wing horses, especially in. 1546 01:21:25,680 --> 01:21:30,840 Speaker 1: A peramutual system, right because you know, the more the 1547 01:21:30,960 --> 01:21:34,120 Speaker 1: more your tip sheet buyers are betting on your horses. 1548 01:21:33,800 --> 01:21:35,479 Speaker 2: The lower guts right exactly. 1549 01:21:35,920 --> 01:21:37,040 Speaker 1: They're betting against. 1550 01:21:38,200 --> 01:21:40,800 Speaker 2: Our final question. Our final question, what do you know 1551 01:21:40,880 --> 01:21:44,679 Speaker 2: about the world of neuroeconomics today, might have been helpful 1552 01:21:45,200 --> 01:21:48,080 Speaker 2: when you were first getting started back in the nineteen eighties. 1553 01:21:50,240 --> 01:21:52,800 Speaker 1: You know, I'll answer that like a politicial answer a 1554 01:21:53,000 --> 01:21:54,760 Speaker 1: question I have a better answer for, which is about 1555 01:21:54,760 --> 01:21:55,639 Speaker 1: behavioral finance. 1556 01:21:55,800 --> 01:21:58,880 Speaker 2: Sure, so either or be fire or sure? 1557 01:21:59,320 --> 01:22:01,479 Speaker 1: I got it. So in your economics, I don't think 1558 01:22:01,640 --> 01:22:03,760 Speaker 1: we made too many mistakes. I think I wish we had. 1559 01:22:04,640 --> 01:22:07,120 Speaker 1: You know, we got a lot of grand support. Caltech 1560 01:22:07,240 --> 01:22:10,040 Speaker 1: was very supportive. I got to know a lot of 1561 01:22:10,120 --> 01:22:12,000 Speaker 1: interesting people who are generous with their time, who were 1562 01:22:12,120 --> 01:22:15,360 Speaker 1: kind of my tutors on neuroscience. I never took any formal, 1563 01:22:16,160 --> 01:22:18,639 Speaker 1: you know, coursework on it. It was came way, way 1564 01:22:18,680 --> 01:22:22,000 Speaker 1: way after my original rad training. So thank you everyone. 1565 01:22:23,280 --> 01:22:25,439 Speaker 1: I wish we had. We have not had much impact 1566 01:22:25,479 --> 01:22:29,560 Speaker 1: in academic economics particularly, and that's something we're kind of 1567 01:22:29,840 --> 01:22:32,640 Speaker 1: working on. Maybe we can do better behavioral finance. I 1568 01:22:32,680 --> 01:22:35,720 Speaker 1: think I started graduate school in the late seventies. In 1569 01:22:35,760 --> 01:22:38,920 Speaker 1: nineteen seventy eight, Mike Jensen published a very influential paper. 1570 01:22:40,000 --> 01:22:42,599 Speaker 1: It was an intruction to a special issue, and one 1571 01:22:42,640 --> 01:22:46,160 Speaker 1: of the first sentences is the market efficiency apothesis is 1572 01:22:46,280 --> 01:22:49,240 Speaker 1: one of the most well established empirical regularities in economics. 1573 01:22:51,120 --> 01:22:55,120 Speaker 1: But but that was like the high water mark, and 1574 01:22:55,240 --> 01:22:58,320 Speaker 1: the special issue was about there's some things that are anomalists, 1575 01:22:58,439 --> 01:23:02,400 Speaker 1: like earnings drift. He got a weird earnings announcement. The 1576 01:23:02,520 --> 01:23:05,200 Speaker 1: market reacts, but then the market reaction drifts up for it. 1577 01:23:05,320 --> 01:23:07,720 Speaker 1: It takes a couple of weeks, almost like food for 1578 01:23:07,800 --> 01:23:10,720 Speaker 1: the market so so absorbed it should not take a 1579 01:23:10,760 --> 01:23:13,400 Speaker 1: couple of weeks, right, right, There were other things where 1580 01:23:13,520 --> 01:23:16,479 Speaker 1: we see, you know, like one within one hour markets 1581 01:23:16,520 --> 01:23:22,960 Speaker 1: are repricing really well. But despite this Jensen article, the 1582 01:23:24,240 --> 01:23:27,520 Speaker 1: hostility to ba Heybalk finance was ferocious. 1583 01:23:28,840 --> 01:23:30,479 Speaker 2: That's a big word at that time. It was that 1584 01:23:30,760 --> 01:23:32,479 Speaker 2: so late seventies, early late. 1585 01:23:32,360 --> 01:23:34,080 Speaker 1: Seventies, early eighties, and so that's when I was kind 1586 01:23:34,080 --> 01:23:35,880 Speaker 1: of deciding do I want to stay in finance or 1587 01:23:35,960 --> 01:23:38,120 Speaker 1: mix it with and I remember having a discussion. I 1588 01:23:38,120 --> 01:23:40,680 Speaker 1: don't know if Jeane remembers it the same way with 1589 01:23:41,000 --> 01:23:43,000 Speaker 1: I had to write a paper for Eugene Fama's course, 1590 01:23:43,040 --> 01:23:44,840 Speaker 1: who was also kind of a mentor in this sense. 1591 01:23:45,120 --> 01:23:47,280 Speaker 1: Even though I didn't end up doing work that was close, 1592 01:23:48,200 --> 01:23:51,000 Speaker 1: you know, he was he was really relentless and very 1593 01:23:51,200 --> 01:23:54,360 Speaker 1: empirically driven, and he had a really good idea. When 1594 01:23:54,400 --> 01:23:57,240 Speaker 1: he started, people were thought he was crazy because there 1595 01:23:57,320 --> 01:23:59,840 Speaker 1: was all this stuff on, you know, there was even 1596 01:24:00,080 --> 01:24:02,320 Speaker 1: he wrote some papers on dividends, like well, the Optimal 1597 01:24:02,439 --> 01:24:05,200 Speaker 1: Dividend Payment Policy, and of course Miller and him would like, 1598 01:24:06,240 --> 01:24:08,360 Speaker 1: what be dividends at all? You just like take money 1599 01:24:08,360 --> 01:24:10,040 Speaker 1: from one bucket and put it in the other. 1600 01:24:11,040 --> 01:24:14,080 Speaker 2: Well, back in the early days of widows and orphan stocks, 1601 01:24:14,120 --> 01:24:15,240 Speaker 2: you people lived on. 1602 01:24:15,280 --> 01:24:17,800 Speaker 1: Their digiti Yeah, exactly because of the liquidity. 1603 01:24:17,600 --> 01:24:19,439 Speaker 2: Right, you don't want to sell do you want to 1604 01:24:19,479 --> 01:24:20,040 Speaker 2: hold on to it? 1605 01:24:20,120 --> 01:24:22,200 Speaker 1: And then the dividends, you know, it is enough to 1606 01:24:22,280 --> 01:24:22,479 Speaker 1: live on. 1607 01:24:22,920 --> 01:24:27,040 Speaker 2: Now the theory has shifted towards uh, it's more efficient 1608 01:24:27,200 --> 01:24:32,160 Speaker 2: return of capital to shareholders doing buybox than dividends. But 1609 01:24:32,520 --> 01:24:36,040 Speaker 2: that's only total return. If you're looking for that income stream, 1610 01:24:36,200 --> 01:24:37,760 Speaker 2: buybacks don't necessarily help you. 1611 01:24:37,880 --> 01:24:40,000 Speaker 1: Right, right exactly. So that's and that's also where the 1612 01:24:40,080 --> 01:24:42,600 Speaker 1: hero economic comes in with you know, why can't you 1613 01:24:42,760 --> 01:24:46,080 Speaker 1: just like create whatever income stream you want by borrowing 1614 01:24:46,160 --> 01:24:49,000 Speaker 1: and selling, right, that's right? And if you know, if 1615 01:24:49,040 --> 01:24:51,439 Speaker 1: you're really liquidity constrained or credit constrained, you can't. But 1616 01:24:51,600 --> 01:24:55,200 Speaker 1: for most people that's not a big deal anyway. So 1617 01:24:55,720 --> 01:24:59,120 Speaker 1: if I had known behavioral finance, would it didn't take 1618 01:24:59,160 --> 01:25:02,080 Speaker 1: off quickly. From nineteen seventy eight, which is Jensen nineteen 1619 01:25:02,120 --> 01:25:05,240 Speaker 1: eighty one, I graduated nineteen eighty five was the failure 1620 01:25:05,280 --> 01:25:10,680 Speaker 1: in DeMont paper about January effects. And even that was 1621 01:25:10,760 --> 01:25:15,200 Speaker 1: published as a It was in the Proceedings issue, which 1622 01:25:15,320 --> 01:25:19,160 Speaker 1: meant that the President of the of the AFA could 1623 01:25:19,320 --> 01:25:22,479 Speaker 1: pan pick papers. So the preceding issue had the most 1624 01:25:22,560 --> 01:25:26,479 Speaker 1: radical papers that were the foundation of aper economics. Fisher 1625 01:25:26,560 --> 01:25:30,360 Speaker 1: Black wrote a paper called Noise Traders. I thot it 1626 01:25:30,439 --> 01:25:33,200 Speaker 1: might have just been called noise. And then Dick Roll 1627 01:25:33,240 --> 01:25:36,040 Speaker 1: wrote a paper got R Squared, and he said, you know, 1628 01:25:36,160 --> 01:25:39,720 Speaker 1: if only news moves the market, right, then the R 1629 01:25:39,800 --> 01:25:42,240 Speaker 1: squared On days with no news, you know, you shouldn't 1630 01:25:42,280 --> 01:25:45,760 Speaker 1: have any volatility, And of course days with big news 1631 01:25:45,880 --> 01:25:50,040 Speaker 1: and small news similar to the story you were telling 1632 01:25:50,040 --> 01:25:53,040 Speaker 1: you in the beginning, Days with big news, big obvious 1633 01:25:53,160 --> 01:25:55,760 Speaker 1: news and hardly any news move about the same. 1634 01:25:57,600 --> 01:25:59,840 Speaker 2: The assumption being by the time it's in the front 1635 01:26:00,040 --> 01:26:03,320 Speaker 2: age of the new York Times, it's already reflected the. 1636 01:26:03,320 --> 01:26:05,360 Speaker 1: Markets, right, But also there may be things that are 1637 01:26:05,400 --> 01:26:08,320 Speaker 1: not newsy at all, Like in October eighty seven crash, 1638 01:26:08,840 --> 01:26:11,840 Speaker 1: you know, the Bundesbank moved rates by a quarter of 1639 01:26:11,880 --> 01:26:12,840 Speaker 1: a point or something. 1640 01:26:13,040 --> 01:26:15,680 Speaker 2: Who cares? That was the big news, right, but you know, 1641 01:26:16,000 --> 01:26:19,240 Speaker 2: you never know when that last straw breaks the camels correct. 1642 01:26:19,360 --> 01:26:21,439 Speaker 1: But but so all those ideas now that that we 1643 01:26:22,040 --> 01:26:23,920 Speaker 1: we you know, we feel like we have an understanding 1644 01:26:24,000 --> 01:26:27,160 Speaker 1: and examples. There was a lot of hostility to that. 1645 01:26:27,280 --> 01:26:33,800 Speaker 1: So I remember asking Gene, I'd like to study market psychology, 1646 01:26:33,920 --> 01:26:36,599 Speaker 1: like what do you know about market psychology? And he said, 1647 01:26:37,520 --> 01:26:41,640 Speaker 1: what's that, Mike? And psychology is Boston accent? You know. 1648 01:26:42,600 --> 01:26:45,120 Speaker 1: I think it's just a word they use on the news, 1649 01:26:45,800 --> 01:26:47,600 Speaker 1: like in Bloomberg. It's just a word they use on 1650 01:26:47,640 --> 01:26:48,800 Speaker 1: the news when the market moved. 1651 01:26:48,800 --> 01:26:51,600 Speaker 2: They don't know why, right, Well, no one wants to 1652 01:26:51,680 --> 01:26:55,160 Speaker 2: admit it's fairly random day to day. We're very humans 1653 01:26:55,200 --> 01:26:58,800 Speaker 2: are very I know that humans are very uncomfortable. 1654 01:26:58,360 --> 01:27:00,920 Speaker 1: And we're good at pattern right. 1655 01:27:01,000 --> 01:27:03,040 Speaker 2: We make up patterns. We come up with a narrative 1656 01:27:03,080 --> 01:27:10,240 Speaker 2: to explain it. I recall Dick Thaylor quoting maybe it 1657 01:27:10,320 --> 01:27:15,519 Speaker 2: was Max Planck, who's talking about physics scientis one funeral 1658 01:27:15,560 --> 01:27:19,280 Speaker 2: at a time. Taylor said the same thing about behavioral finance, 1659 01:27:19,360 --> 01:27:22,400 Speaker 2: and he also said, I'm bypassing the current generation and 1660 01:27:22,439 --> 01:27:25,600 Speaker 2: going right to the kids so they'll adapt a wholesale 1661 01:27:25,760 --> 01:27:29,680 Speaker 2: and literally he said, I'm teaching grads and undergrads this 1662 01:27:30,240 --> 01:27:32,240 Speaker 2: so we don't even have to wait for the funeral. 1663 01:27:32,360 --> 01:27:36,599 Speaker 2: And it seems to have worked. Oh yeah, no, absolutely, Colin, 1664 01:27:36,920 --> 01:27:39,439 Speaker 2: thank you so much for being so generous with your time. 1665 01:27:39,560 --> 01:27:44,080 Speaker 2: This has been absolutely fascinating.
