Speaker 1: M Hey everybody, it's me Josh, and for this week's
Speaker 1: S Y s K Select, I've chosen an episode on Placebos.
Speaker 1: It's an episode chock full of facts of the podcast,
Speaker 1: and yet Chuck comes out with one of the all
Speaker 1: time greats right out of the gate. But don't stop listening.
Speaker 1: Then the whole episode is amazingly wonderful, which is why
Speaker 1: I chose it. So enjoy it. Welcome to Stuff you
Speaker 1: should know, a production of I Heart Radios How Stuff Works. Hey,
Speaker 1: and welcome to the podcast. I'm Josh Clark, and there's
Speaker 1: Charles W. Chuck Bryant, and there's Jerry Jerry place cebo,
Speaker 1: do sir? No? No, that was bad, Chuck. Yes. Have
Speaker 1: you ever heard of the word placebo? Do sir? Yeah? Placebo?
Speaker 1: You know what I mean. I'll tell every buddy, I
Speaker 1: shall see, No, I will please, I shall please. That's
Speaker 1: what I meant. I shall see. We'll see about that.
Speaker 1: I shall please. That's what I meant in Latin. Yes, right,
Speaker 1: so placebo. Everybody's heard of a placebo, and very famously
Speaker 1: the placebo effect. Do you wonder where that comes from?
Speaker 1: The placebo effect? The word placebo um fourteenth century. It
Speaker 1: referred to hired mourners at funerals. What they would hire
Speaker 1: mourners in place of family members, and they would start
Speaker 1: their morning wailing with that mourning. But as in m O,
Speaker 1: you are with placebo domino in region vivorum, which means
Speaker 1: I shall please the Lord in the land of the living.
Speaker 1: But in that it means placebo. Uh this article, so
Speaker 1: it carries the connotation of substitution. Weird. Yeah, that is
Speaker 1: fantastic stuff, I thought. So this is from placebos and
Speaker 1: placebo effects in Medicine. Colon Historical Overview by Tisson cap
Speaker 1: Chuck Green and Legion Catchuck. That guy is high quality. Yeah,
Speaker 1: a lot of skeptics Catchuck, Catchuck. He's at Harvard. Let
Speaker 1: me tell you a little bit about Ted Kapchuck the
Speaker 1: coney Allen cap Chuck's I just raised a lot of
Speaker 1: skeptics hackles because some people see him as a huckster
Speaker 1: of fraud or everything that's wrong with placebos. These people,
Speaker 1: um would probably have a problem with us even talking
Speaker 1: seriously about the placebo effect in the first place. So
Speaker 1: I don't know that it's a really big deal that
Speaker 1: I just raised their hackles. But Ted Catchuk is a
Speaker 1: former owes me fifty bucks. Right, let me tell you
Speaker 1: about Catchuck. Now. He's a former acupuncturist, and he apparently
Speaker 1: had some sort of um epiphany one day when he
Speaker 1: was he was treating somebody and they started to feel
Speaker 1: better before he even used the acupuncture. So he started wondering, like, okay,
Speaker 1: what's going on here? And he started investigating the placebo effect,
Speaker 1: and in short order he ended up as an instructor
Speaker 1: at Harvard and became one of the leading researchers into
Speaker 1: the placebo effect, which is a really strange journey because
Speaker 1: Harvard Medical School doesn't usually hire acupuncturists. And he had
Speaker 1: like kind of a rocky road at first, like he
Speaker 1: didn't know what he was doing with clinical trials, and
Speaker 1: he got publicly called out in the New England Journal
Speaker 1: of Medicine and UM over the years, over the decades,
Speaker 1: I think this is the eighties that he really started
Speaker 1: to look into it. He um, like I said, became
Speaker 1: the foremost researcher in in coming up with quality clinical
Speaker 1: trials for trying to get to the root of what
Speaker 1: the placebo effect is and how to use it. What
Speaker 1: years was that, you know, he's still doing it. But
Speaker 1: when was this? When he was started all that stuff,
Speaker 1: he got called out and I think a two thousand
Speaker 1: one issue of the New England Journal of Medicine, UM,
Speaker 1: basically for not using a control group in his placebo study.
Speaker 1: So you know, when you do a study, you have
Speaker 1: a placebo group which is your control group, and that
Speaker 1: basically is I'm giving you real medicine, but I'm giving
Speaker 1: Jerry a sugar pill. And in a proper study, I
Speaker 1: don't know who's getting the sugar pill and who's getting
Speaker 1: the medicine. It's called double blind, right, um. So you know,
Speaker 1: if you're studying just the placebo effect, I should be
Speaker 1: giving you a placebo and I should be giving Jerry
Speaker 1: no treatment whatsoever. To truly, I thought you needed three people,
Speaker 1: one with a real treatment, one with placebo, and one
Speaker 1: with no treatment. It's another way to do it, Okay,
Speaker 1: at the very least, though, you need the placebo group
Speaker 1: and somebody who's receiving no treatment. Gotcha, you see. Yeah, yeah,
Speaker 1: if we're skinning cats, well, if you're doing good science
Speaker 1: researching into the placebo. But what's ironic is is this
Speaker 1: whole double blind placebo study came about because the placebo
Speaker 1: effect was first noticed by Western practitioner by the name
Speaker 1: of Dr Henry Beecher, who in World War Two supposedly
Speaker 1: saw a nurse give a shot of sailine to a
Speaker 1: soldier because they'd run out of morphine. But the nurse
Speaker 1: told them it was morphine, and the soldier responded to
Speaker 1: this shot of sailine like it was morphine, And from
Speaker 1: that Beecher was like, what is going on here, started
Speaker 1: to investigate the placebo effect and ended up proposing the
Speaker 1: double blind placebo study to prove the efficacy of drugs.
Speaker 1: It goes back further than that, my friend, let's hear
Speaker 1: it man uh try sev five the New Medical Dictionary,
Speaker 1: they described the placebo as a commonplace method or medicine,
Speaker 1: and then a short time later, in eighteen eleven and
Speaker 1: Quincy's lexicon uh Medicum, he defined the placebo as an
Speaker 1: epithet given to any medicine adapted more to please than
Speaker 1: to benefit the patient, like heroin. So they were on
Speaker 1: it back in the early eighteen hundreds, which is surprising. Yeah,
Speaker 1: but I mean, like that's the basis of like snake
Speaker 1: oil and hucksterism, right, Yeah, Well, they called him bread
Speaker 1: pills back then, because I guess it was. It was
Speaker 1: probably some sort of like pill made of yeast. As
Speaker 1: my guests UH and Thomas Jefferson in eighteen o seven
Speaker 1: even recorded what he called the Pious Fraud, and he
Speaker 1: observed quote that one of the most successful positions I've
Speaker 1: ever known has assured me that he used more bread pills,
Speaker 1: drops of colored water, and powders of hickory ash than
Speaker 1: all other medicines put together. Um. And people treated people
Speaker 1: with bread pills in the early eighteen hundreds. It was
Speaker 1: a thing, and like they were way onto the placebo
Speaker 1: effect and and the fact that it seemed to work.
Speaker 1: UH and another dude named John Haygarth in the early
Speaker 1: eighteen hundreds UH actually started performing the first studies on
Speaker 1: placebo's effect and UM, he said it went back to
Speaker 1: the Renaissance idea that imagination was the major mediator between
Speaker 1: body and mind, which is starting to be proven is
Speaker 1: possibly correct. Yeah, it's pretty interesting. And in the nineties
Speaker 1: is when they started publishing papers on the placebo U
Speaker 1: and actually doing clinical trials and UM. They said one
Speaker 1: of their points in the nineteen thirties would confidence aroused
Speaker 1: in a treatment, the encouragement afforded by a new procedure,
Speaker 1: even like just people getting treated in a new way.
Speaker 1: People would say, oh, well, this is gonna work, and
Speaker 1: it maybe he did work. And then we're up to
Speaker 1: the forties where Beacher comes along notices the placebo effect
Speaker 1: himself ultimately comes up with the double blind placebo based study.
Speaker 1: And what's ironic about that is the placebo based double
Speaker 1: blind study ultimately has split back off into the study
Speaker 1: of placebo again. Yeah, because there are so many trials
Speaker 1: where the placebo was more effective than the drug, even
Speaker 1: though the drug worked, but the placebo worked even better.
Speaker 1: And finally in the nine people were like, what is
Speaker 1: going on here? We need to study this thing in
Speaker 1: and of itself. Well, yeah, because one of the things
Speaker 1: I had no idea. I thought placebos were only used
Speaker 1: in studies for efficacy rates. I did not know that
Speaker 1: they are. There are doctors, always have been, and still
Speaker 1: are prescribing placebos as medicine unknowingly even though they're not
Speaker 1: supposed to. We'll get to that later. No knowingly, no
Speaker 1: unknowingly for the patient, even though they're supposed to tell
Speaker 1: the patient. Yeah, but we'll get to that towards the end,
Speaker 1: but I had no idea that they were prescribing placebos
Speaker 1: to people. Yeah, And in their defense, a lot of
Speaker 1: times doctors are carrying on a tradition where they don't
Speaker 1: have anything else to prescribe. But they can't say if
Speaker 1: they say that to their patients, their patients is going
Speaker 1: to go off and suffer. So at the very least
Speaker 1: they can use the last ditch attempt of saying psychological trickery. Yeah, yeah,
Speaker 1: And I'm not knocking to I just was surprised to
Speaker 1: learn that that still happens. And I'm wondering if I've
Speaker 1: ever been given a placebo. And it makes me feel
Speaker 1: dumb as a patient to say, like, yeah, man, that
Speaker 1: whatever you give me really helped. And the doctors like
Speaker 1: because it's the same thing as that prank of like
Speaker 1: giving somebody non alcoholic beer and telling it's a real
Speaker 1: beer and watching them make a jerk out of themselves
Speaker 1: getting drunk. It's exactly the same thing. So let's talk
Speaker 1: about placebo. We assume that everybody knows what placebo is,
Speaker 1: but let's define it a little more clearly. The placebo effect, specifically,
Speaker 1: is the very real phenomenon that people when given a
Speaker 1: pill or a some sort of medical intervention, that feel better. Yes,
Speaker 1: they feel better, even though what they've been given is
Speaker 1: not medicine and is was not actually a real intervention. Yeah.
Speaker 1: And the placebo is the pill itself. That that that is
Speaker 1: the placebo, and the effect is what you just described, right,
Speaker 1: And it doesn't have to be a pill. It can
Speaker 1: be an injection, it can be fake surgery, there's true.
Speaker 1: And it doesn't even have to be uh, pharmacologically inert
Speaker 1: It can be a vitamin or like an aspirin, even
Speaker 1: though some argue that's not a true placebo. But um,
Speaker 1: sometimes that's what the doctor will give you, uh and
Speaker 1: call it, you know, medication. But there there um very
Speaker 1: often things like a sugar pill. Yeah, like you said,
Speaker 1: pharmacologically inert um. And astoundingly, depending on the size of
Speaker 1: the pill, the shape of the pill, the color of
Speaker 1: the pill, people will have different effects and responses to
Speaker 1: these things that are just sugar. Um. So there's some
Speaker 1: really strange psychological things going on here. And at first,
Speaker 1: for a long time, everybody just kind of assumed it
Speaker 1: was just psychology, that we we're tricking ourselves into feeling better,
Speaker 1: or we hadn't really felt bad in the first place,
Speaker 1: and we were being tricked into not feeling bad any longer,
Speaker 1: or not thinking we were feeling bad any like an
Speaker 1: offshoot of hypochondria, maybe very much. So. Yeah, um, they
Speaker 1: this article says they've been shown to work in about
Speaker 1: thirty percent of patients, and that was actually that's based
Speaker 1: on Beacher's finding. It was like thirty thirty five point two. Yeah,
Speaker 1: that's what he found out in nine that's what they're
Speaker 1: still basing that on. Yeah, but there's been other studies
Speaker 1: that have gone back through Beacher's studies and said, no, no, no,
Speaker 1: that's not that much. Other people have found up to
Speaker 1: six respond to it, right, And basically one of the
Speaker 1: big questions is is it a psychological effect or are
Speaker 1: there excell actual physical responses that are going on. And
Speaker 1: there's been a lot of research lately that's pretty interesting,
Speaker 1: I think. Right. So, like we were saying that the
Speaker 1: the initial idea was that it was all psychological, right, yeah, Like, uh, well,
Speaker 1: I guess we can talk about the two effects. The
Speaker 1: subject expectancy effect, which is basically, if you know the
Speaker 1: result ahead of time and the pill you're gonna take,
Speaker 1: you're gonna end up feeling that result, right. So that's
Speaker 1: what a blind study seeks to prevent, is a subject
Speaker 1: expectancy effect and also the observer expectancy effect, which is
Speaker 1: what a double blind study seeks to prevent. Yeah, and
Speaker 1: that's important because it's are different because it's all self reported, right,
Speaker 1: which is always a little you know, right. So the
Speaker 1: other idea, if it has a psychological basis, is that
Speaker 1: it's classical conditioning. That we are raised from birth to
Speaker 1: think that if somebody gives you a pill, you're going
Speaker 1: to respond to it because it has medicine. Yeah, and
Speaker 1: that is not self reported. That is actually seeing physical responses, right.
Speaker 1: And with classical conditioning established very famously by Pavlov and
Speaker 1: his dogs, right, um, you are you're having you're responding
Speaker 1: physically to a psychological stimulus, right, so you you are
Speaker 1: getting a physiological response. So classical conditioning eventually kind of
Speaker 1: came to be viewed as the more um reasonable explanation
Speaker 1: for what was going on, because, uh, study after study
Speaker 1: after study has shown that we are having a physical
Speaker 1: reaction to these inert placebos. Yeah, one of them in
Speaker 1: two thousand two from U. C. L As Neuropsychiatric Institute.
Speaker 1: They had a couple of groups of patients and a
Speaker 1: lot of the placebo studies are uh for mental conditions. Um,
Speaker 1: not all of them, but a lot of them are
Speaker 1: or in UM like the clinical trials. Yeah, yeah, exactly. UM.
Speaker 1: So this one was for any depressants, and they had
Speaker 1: two groups that got UM experimental drugs like real drugs,
Speaker 1: and then the third was given the placebo. Uh. They
Speaker 1: spent a few weeks on these pills and monitored their
Speaker 1: brain activity with the old E. G. Wonder machine and
Speaker 1: well it's not the Wonder machine, the Mrs Wonder, it's
Speaker 1: it's a wonder machine, not the Wonder machine. Uh. And
Speaker 1: the patients on the placebo reported positive effects and showed
Speaker 1: greater increase of brain activity than those who had responded
Speaker 1: to the drug. You know, I remember that it was
Speaker 1: the study. Yeah, totally undermined people's faith in antidepressants because
Speaker 1: it was on the other end of like the whole
Speaker 1: nineties where everybody was on antidepressants and wasn't This study
Speaker 1: came out and was like people were saying, like, do
Speaker 1: these things even work? It was it was kind of
Speaker 1: taken the opposite way rather than Wow, the placebo effect
Speaker 1: is really something. It was wow and it depressence, right, fraudulent,
Speaker 1: right right? Right? Well, I wonder what they were trying
Speaker 1: to It was a placebo study though, right, so it
Speaker 1: kind of backfired or did they even care? No, I
Speaker 1: think it very much cared because there when compared to
Speaker 1: place with the whole point of a drug trial is
Speaker 1: to show that this drug is more effective than placebo.
Speaker 1: It's more effective than the imagination, right right, And if
Speaker 1: it's not, then that means that drugs shouldn't be brought
Speaker 1: to market. Even though now the thinking is more like, hmm,
Speaker 1: that's not necessarily true, because we're coming to understand the
Speaker 1: placebo effect can be very powerful, especially depending on the
Speaker 1: individual too. Yeah, for sure. Uh. The interesting thing about
Speaker 1: that study is when the E E G. Lit up um,
Speaker 1: the activity was in different parts of the brain. Um
Speaker 1: that I think that the placebo patients said the preformal
Speaker 1: cortex was lighting up, and basically that says that the
Speaker 1: brain isn't being fooled, it's just doing something different. Yeah,
Speaker 1: they responded better to the treatment then the people who
Speaker 1: responded to the drug. So some people did respond to
Speaker 1: the drug, but different parts of their brain were activated
Speaker 1: by the drug than the people who responded well to
Speaker 1: the placebos, right, even though they felt better. Yeah, that's
Speaker 1: mind boggling. It is. So they had they reached the
Speaker 1: same conclusion but using a totally different regions of their brain,
Speaker 1: and they actually felt better. Um. That wasn't the first
Speaker 1: study to prove that there is a physiological response to
Speaker 1: placebos or last there's a dental study from the seventies
Speaker 1: that I think was the first that showed that if
Speaker 1: you blocked endorphins, which are nature's pain relievers, uh, you
Speaker 1: can also block the placebo effect. So the people weren't
Speaker 1: responding to the placebo like you would expect them to
Speaker 1: a pain reliever placebo because they weren't able to release
Speaker 1: their natural pain relievers. Yeah, and that's backed up I
Speaker 1: guess by this two thousand four study from the University
Speaker 1: of Michigan, uh Go wolverines. They basically demonstrated that it
Speaker 1: is related to endorphins specifically. Uh So that I guess
Speaker 1: that backs up that study because if you can block them.
Speaker 1: So here's the thing. It's not that study was related
Speaker 1: to endorphins specifically. Other studies have found that it can
Speaker 1: be related to how much a person expresses dopamine specifically.
Speaker 1: So there's like this idea that there's a genetic basis
Speaker 1: to our predisposition to UM placebos. But I think that
Speaker 1: it's depending on the drug or the effect that you're
Speaker 1: trying to induce using the placebo effect, because think about it,
Speaker 1: if you are somebody who naturally produces more endorphins than
Speaker 1: somebody else, Uh, you're going to naturally produce more endorphins
Speaker 1: when it's UM triggered by a placebo than somebody who
Speaker 1: doesn't produce more endorphins naturally. So there's a genetic basis
Speaker 1: to it, I guess. But I think the genetic basis
Speaker 1: is that the individual must be predisposition to be able
Speaker 1: to have that genetic response UM to the drug or
Speaker 1: the placebo and have that that UM I guess response
Speaker 1: to it. Yeah, And it's like you said, it's also
Speaker 1: personal because they found that it is even affected by
Speaker 1: a person's personal experience with past pills. The color of
Speaker 1: the pill, the shape and size of the bill will
Speaker 1: have a different reaction because the person had maybe took
Speaker 1: another little blue pill for something else. Sure, and actually
Speaker 1: blue pills in in particular are known to be um
Speaker 1: to have sedative effects as place Ebo's red pills are
Speaker 1: known to have stimulating and pain relieving effects as placebo.
Speaker 1: That's odd that they made viagrab blue. Yeah, like inhabitedly
Speaker 1: marketed it as the little blue pill. Interesting sedative effect, Yes,
Speaker 1: I don't think so, so, Chuck, Well, not that i'd know. Well,
Speaker 1: we've got more stuff about all this coming up. I
Speaker 1: don't know what we're going to talk about next. It's
Speaker 1: a grab bag right now. We're back, buddy, and I
Speaker 1: tell you what we're going to talk about. Something that
Speaker 1: I had never heard of, which I think is super interesting,
Speaker 1: the no sebo effect. It is super cool. And that
Speaker 1: is when well, it's a there's a couple of things.
Speaker 1: That is, when you are taking a placebo and you
Speaker 1: experience maybe the effects of the pill, which is great,
Speaker 1: and the side effects of that pill that you think
Speaker 1: might be but you're supposed to have, right, you're actually
Speaker 1: experiencing side effects that aren't shouldn't be there, right, And
Speaker 1: it's a sugar pill. They noticed this in clinical trials too,
Speaker 1: because when you're carrying out a clinical trial, you have
Speaker 1: to warn the patients, Yeah, this drug may give you
Speaker 1: these terrible side effects, and so they started noticing like
Speaker 1: people who were who were on placebo, we're still experiencing
Speaker 1: the side effect like physical reactions like hives and itching
Speaker 1: in things. Right, so there is a there's a negative
Speaker 1: side to placebo as well, and no sebo means I
Speaker 1: shall harm like placebo means I shall please. Yeah, yeah um.
Speaker 1: And they found that and this is definitely backed up
Speaker 1: by the idea that it's classical conditioning. They found that
Speaker 1: people who have gone through chemotherapy can become nauseated when
Speaker 1: they enter a room that's painted the same color as
Speaker 1: the room where they receive chemo before. Yeah, that makes sense. Yeah,
Speaker 1: So there's all sorts of ways that the no sebo
Speaker 1: effect can pop up, but it's pretty mind boggling as well. Yeah,
Speaker 1: and then no seabow can doesn't even have to be
Speaker 1: just with the placebo. You can experience side effects that
Speaker 1: aren't on the list of a real drug because of
Speaker 1: what we were talking about, because it looked like another
Speaker 1: pill you might have had before. Man, the brain powerful stuff. So,
Speaker 1: going back to Kapchuk, whom I'm just kind of a
Speaker 1: fan of, Yeah, I think if you're into like a
Speaker 1: long form articles, which I love. Go to Harvard Magazine
Speaker 1: and search for the placebo phenomenon and it's a profile
Speaker 1: at him and his work. It's really interesting stuff. But
Speaker 1: he was saying that kind of in line with the
Speaker 1: idea that like the color of the pill or the
Speaker 1: shape of the pill will have an effect, won't either
Speaker 1: on the no sebo or the placebo effect. Um. He
Speaker 1: was saying that it seems like the basis of the
Speaker 1: placebo effect is what's called ritual, and ritual is it
Speaker 1: involves everything from like the physician's bedside manner, to how
Speaker 1: expensive the patient thinks the pill is, to how effective
Speaker 1: the patient thinks the pillows and um. He did a
Speaker 1: study where he carried out what was called schmaltzy um,
Speaker 1: like a schmalty care to where he was just lavishing
Speaker 1: attention on the patient and telling him how bad he
Speaker 1: felt that they were going through this, but this pill
Speaker 1: is really effective with your condition. And apparently not just
Speaker 1: this study, but other studies show that there's a positive
Speaker 1: correlation between the ritual yeah and response to the placebo effect.
Speaker 1: So the more you think that this drug is expensive,
Speaker 1: that this drug is effective, that this physician cares about you,
Speaker 1: the greater of a placebo response you're going to have. Yeah,
Speaker 1: you know, I have you ever been accused of being
Speaker 1: a hypochondract by anyone? Know, it's kind to be very demeaning.
Speaker 1: It is because it happened to me. Oh yeah, Yeah.
Speaker 1: I went to the emergency room in New York, as
Speaker 1: you know, when we were up there recently for our trip.
Speaker 1: I went to the e R and uh something, it
Speaker 1: was something and it was a result of it was
Speaker 1: it was throwing up in uh nausea from UM I
Speaker 1: learned from anti inflammatory pills I was taking at the
Speaker 1: time for something else. I had nothing to do with
Speaker 1: being sick, and they figured that out, but they kept.
Speaker 1: You know, this guy, I called him Nurse Jackie. He
Speaker 1: was just like Nurse Jackie exap. He was a dude.
Speaker 1: He kept coming by and treating me with things and
Speaker 1: giving me the I V. Drip And I was like, dude,
Speaker 1: I'm not feeling better and I'm not a hypochondric in
Speaker 1: any way. I didn't go to the doctor for like
Speaker 1: eighteen years straight. And uh, I could tell he was
Speaker 1: looking at me like I got one of these guys. Yeah,
Speaker 1: And I was like no, no, And I could tell
Speaker 1: I could could sense it, and so he finally gave
Speaker 1: me this thing to drink that um knocked me out.
Speaker 1: I woke up like twenty minutes later and felt felt better.
Speaker 1: What was it, I can't remember. It was something to
Speaker 1: gata now. It was like three different things. It was
Speaker 1: like a cocktail of stomach pleasing things and what's the
Speaker 1: stuff that like numbs? You numb my throat? And I
Speaker 1: can't remember light to cane, I think um and it
Speaker 1: worked with Yeah, it worked. I woke up and I
Speaker 1: felt better. I said, you know, I don't feel so
Speaker 1: nauseous now, and they were checking me out and I
Speaker 1: reached up and I felt behind my ear for some reason,
Speaker 1: and it felt like a golf ball behind my ear.
Speaker 1: And it popped up in the last twenty minutes, and
Speaker 1: so I was literally leaving. I was like, oh, wait
Speaker 1: a minute, I got this thing behind my ear all
Speaker 1: of a sudden, and this guy looked at me like
Speaker 1: h and he called the doctor over and she was like, yeah,
Speaker 1: it's it's very swollen at your lymph node. But he
Speaker 1: wasn't there for that, so he came back over. He's like, hey,
Speaker 1: what did she say? I said, well, she said the
Speaker 1: swollen and he said that you're a hypochondriac. And I
Speaker 1: was so mad. It nursed Jackie. I was like, dude,
Speaker 1: look at it. It's huge. I'm not making this up.
Speaker 1: And I started defending myself like I never go to
Speaker 1: doctors and I'm not one of those people. And he
Speaker 1: was just he was like, I was just kidding. I
Speaker 1: was just kidding, and I was just kidding. Yeah, but
Speaker 1: it made it totally made me feel like a jerk. Yeah,
Speaker 1: I mean imagine if like you, if that happened to
Speaker 1: you a lot too. I mean that's all that means,
Speaker 1: you're a hypochondriact. But now it definitely made me felt
Speaker 1: and I know he was kidding, but it made me
Speaker 1: feel really bad, like I'm in there just uh, what's
Speaker 1: what's the syndrome? Lynch? Is that it? Yeah? We did
Speaker 1: want an episode on that too. Yeah, uh, anyway, sorry
Speaker 1: about that. Yeah, well I'm sorry that that happened to you. Thanks.
Speaker 1: I mean that is b s. But you mentioned the
Speaker 1: I V guarantee you that was just sailing, and that's
Speaker 1: a placebo in itself. No, I mean they told me that.
Speaker 1: I mean they didn't say like that this is the
Speaker 1: wonder bag, right, But there's basically, I'm no reason to
Speaker 1: give you sailine solution well to hydrate me. I guess
Speaker 1: if i'd been throwing up. Oh yeah, okay, but um yeah,
Speaker 1: I guess you're right though, to see like something dripping
Speaker 1: into your arm, like, surely that's got to be doing something. Yeah. Uh. Well,
Speaker 1: one interesting thing is back to placebo's there have been
Speaker 1: studies that have shown that, uh, if you don't tell
Speaker 1: the patient what they're supposed to do, that they don't
Speaker 1: work as well. Yeah. They even found that with drugs
Speaker 1: that they know for a fact work. Yeah, if you
Speaker 1: don't tell them, it won't work. Yeah. They did a
Speaker 1: placebo based trial with a pain killer and the pain
Speaker 1: killer proved more effective than placebo. And then they did
Speaker 1: another trial with the same pain killer, didn't tell anybody
Speaker 1: what it was and it didn't work. Interesting. And then conversely,
Speaker 1: this is the one that gets me, the study where
Speaker 1: they so crazy. They used an injection that they put
Speaker 1: into patient's jaws in the study, which is mean to
Speaker 1: induce pain, Like that was the point. They were trying
Speaker 1: to induce pain in somebody's jaw using harmless but painful
Speaker 1: jaw injections, and they would inject sailine into the jaw
Speaker 1: um to keep the patient's self reported pain level steady
Speaker 1: throughout the study. And then they used another injection and
Speaker 1: gave them sailine but told them this was a pain reliever,
Speaker 1: and everybody's pain across the board dropped as a result
Speaker 1: in the study. Unbelievable placebo effect. I could just sit
Speaker 1: around and rattle off studies all day. It's pretty interesting.
Speaker 1: What do you think about obacalp. Yeah, it seems kids
Speaker 1: are done. You kid just call it placebo anyway, I
Speaker 1: think it's unnecessary. Well, Obacalp is placebo spelled backwards obviously,
Speaker 1: and that in two thousand and eight was I guess,
Speaker 1: sort of invented or not invented, but coined and packaged
Speaker 1: by a mother I think Australian named jin Boutner. She Australian.
Speaker 1: I don't know. I think so is that an Australian
Speaker 1: last name? And then I don't think there's such a
Speaker 1: thing um, And so that's basically Placebo's for kids. It's marketed.
Speaker 1: You can you can buy a bottle of obacalp, and
Speaker 1: it's for when your kid isn't feeling good. But um,
Speaker 1: you but you know, your kids not sick, that kind
Speaker 1: of thing, and so you give the kid the pill
Speaker 1: and it makes them feel better. And some people have
Speaker 1: problems with this and say, you're teaching your child that
Speaker 1: you get relief from pills only when they're you know,
Speaker 1: I don't necessarily need to be taking pills all the time.
Speaker 1: And proponents say, you know what, it's it's the same
Speaker 1: thing as putting a bandage or kissing a boo boo.
Speaker 1: It's like you said, these are dumb little kids. Well,
Speaker 1: I remember growing up with the children's aspirin, the orange aspirin.
Speaker 1: I'm pretty sure those were just sugar pills. You think.
Speaker 1: I ate a whole bottle of them when I was fine,
Speaker 1: But those were vitamins. It was children's aspirin. Oh, I
Speaker 1: think they were orange flavored. Yeah, I totally remember those. Yeah,
Speaker 1: I think those were probably a placeba. I remember the taste,
Speaker 1: like I can still sense that they were good, a
Speaker 1: whole bottle of them once. Because I was a little
Speaker 1: fat kid. You didn't eat and get sick those sugar pills.
Speaker 1: I have I think so, because I even remember I
Speaker 1: was old enough thinking like I probably shouldn't have eaten
Speaker 1: that whole bottle of those things because it's medicine, and
Speaker 1: watched it down with the sky and I was right
Speaker 1: and that was fine. Afterwards, Well, they do have legit
Speaker 1: baby aspirin now though they I'm starting to doubt every thing,
Speaker 1: so start to talk about doubt. There are plenty of
Speaker 1: criticisms of all this, and we'll talk about him right
Speaker 1: after this. So Chuck, I'm a big time into the
Speaker 1: placebo effect. I can tell your big time into the
Speaker 1: placebo effect. There are people who are not that's true.
Speaker 1: There Uh. It raises plenty of skepticism, which again is
Speaker 1: one of the reasons why my hat is off to
Speaker 1: Ted Katchuk, because he has responded to the criticism. He's
Speaker 1: adjusted his methodology. He's doing really good science in the
Speaker 1: investigation of the placebo effect. I like that guy. Still,
Speaker 1: skeptics say, there are a lot of things that you
Speaker 1: can use to explain away the placebo effect. For example,
Speaker 1: it's possible the person was actually a hypochondriac. They were
Speaker 1: and actually sick in the first place. Yeah, it's possible
Speaker 1: that some people get better with no treatment. Yeah, it's
Speaker 1: possible that some diseases do treat themselves just get better.
Speaker 1: Over the course of time. And if if you overlay
Speaker 1: a placebo effect or placebo and and you put that
Speaker 1: over the same course of time, it's gonna look like
Speaker 1: it was the placebo that did it, when really it
Speaker 1: just healed itself. Yeah, which is why they critics call
Speaker 1: for studies where there is one group that has not
Speaker 1: given any medication whatsoever exactly, which makes sense. So UM.
Speaker 1: One of the other criticisms though, is that if a
Speaker 1: doctor is is saying and there are, like you said,
Speaker 1: plenty of doctors who do this. Um. There there were
Speaker 1: studies that found that UM. A two thou seven study
Speaker 1: from the University of Chicago from doctors surveyed in the
Speaker 1: Chicago area had prescribed placebos before at some point during
Speaker 1: their career. In two thousand and eight, they did a
Speaker 1: little more robust when six centre doctors all across the
Speaker 1: US and half of them said that they had prescribed placebos.
Speaker 1: So this is like, this is still going on. It's
Speaker 1: a thing. It's pretty widespread. Yeah, And the criticism is, well,
Speaker 1: that means doctors are lying to their patients, they're using
Speaker 1: deception to practice medicine, and that's unethical. So the A
Speaker 1: M A came out with it's a guideline that's kind
Speaker 1: of flies in the face of the placebo effector of
Speaker 1: the idea that if you give somebody a placebo and
Speaker 1: tell them it's a placebo, that it shouldn't work, which
Speaker 1: is not necessarily true. Yeah. In two thousand six, the
Speaker 1: Amy came out and said, uh, quote, physicians may use
Speaker 1: placebos for diagnosis or treatment only if they patient is
Speaker 1: informed and agrees to it. To me, that means it's
Speaker 1: not a placebo. I mean, I guess it is, but
Speaker 1: if you know it is, I don't get it. Like,
Speaker 1: what's the point of a doctor coming in and saying,
Speaker 1: I'm going to give you the sugar pill? Would would
Speaker 1: you like a prescription for sugar pills? And you say yes?
Speaker 1: I would suppose believe there are um studies that show
Speaker 1: the placebo effect is still post works sometimes, but the
Speaker 1: across the board pretty much everyone believes that if the
Speaker 1: placebo effect is a real thing, the cats out of
Speaker 1: the bag. It is part of the imagination, and that
Speaker 1: you do kind of have to fool the person into
Speaker 1: thinking that it's a real thing. That expectation coupled with
Speaker 1: imagination provides the placebo effect Yeah, and this article points
Speaker 1: out to we're not just saying these doctors are lying
Speaker 1: liars um. Apparently, one one tech that a doctor can
Speaker 1: take is to say, uh, I have something that I
Speaker 1: think can help, but I don't exactly know what the
Speaker 1: deal is with it or how it works, but i'll
Speaker 1: give it to if you want to try it. And
Speaker 1: you know, people are a lot of people are like, sure,
Speaker 1: I'll try anything. Right, Exactly, that's not really deception because
Speaker 1: if the doctors are prescribing a placebo, he or she
Speaker 1: obviously does believe in the placebo effects. So here she
Speaker 1: does think it could work but doesn't know how, or
Speaker 1: if it only really does work in of the population,
Speaker 1: then you've got a seventy chance of striking out anyway
Speaker 1: with this course of treatment. Uh So you're back to
Speaker 1: where he started to begin with. Yeah, and again it's
Speaker 1: cut that falls inunder what's the point category. Now, again,
Speaker 1: we should say that a lot of physicians who do
Speaker 1: prescribe placebos aren't just doing it to toy with their patients.
Speaker 1: They're doing because they think that their patient will suffer
Speaker 1: more without it, or they just don't have anything that
Speaker 1: could be used to address the patient's problem, like they
Speaker 1: can't find anything medically wrong with the patient, but to
Speaker 1: saying that the patient's not going to help, so here's
Speaker 1: a sugar pill. Um. The other tech that a doctor
Speaker 1: can take to chuck is um to say, hey, new patient,
Speaker 1: welcome to my practice. Let me tell you about the
Speaker 1: placebo effect. And in the course of me treating you,
Speaker 1: sometime during your lifetime, I may find that a placebo
Speaker 1: will be the best thing to use. Are you okay
Speaker 1: with me doing that to you at some point possibly
Speaker 1: basically like signing up for my own personal long term
Speaker 1: study kind of as a doctor. But wouldn't you from
Speaker 1: that point on be like, you just gave me the placeboy,
Speaker 1: it's a placebo. Yeah, I know it's a placebo. I
Speaker 1: wouldn't know which way was up, Like, I don't know
Speaker 1: how to feel that's the better worse side effects none, yep.
Speaker 1: And the other tech doctors can take is to knock
Speaker 1: off early and go hit the golf course, which they
Speaker 1: do that one a lot on TV. That's a that's
Speaker 1: a that's such an old bit trope. It's like, yeah,
Speaker 1: cops in their donuts, is that doctors in golf? I
Speaker 1: think that's pretty accurate. I mean in Caddyshack, the doctor
Speaker 1: was Dr Beeper. He was the one who just got
Speaker 1: mad all the time. Right now, that was Judge Smails.
Speaker 1: Dr Beeper was he was just one of the guys,
Speaker 1: one of the foursome, okay that I think he played.
Speaker 1: Was it Buck Henry? Was he the doctor? No, I can't,
Speaker 1: I can. I can picture the guy. It's Buck Henry, right?
Speaker 1: Is that? I don't think? So we'll figure this out offline.
Speaker 1: How about that? Yeah? All right? If you want to
Speaker 1: know more about the placebo effect, and believe us, there
Speaker 1: is plenty more to know about it, you can type
Speaker 1: those two words in the search part how stuff works
Speaker 1: dot com. And uh, since I said that, it's time
Speaker 1: for listener mail, I'm gonna call this Australian last name.
Speaker 1: This is, he says, dear Josh, Chuck and Jerry and
Speaker 1: anyone else I should think, And I think we never
Speaker 1: mentioned other people that support us. Didn't we already talk
Speaker 1: about in Australian last name? Yeah, that was the joke. Okay,
Speaker 1: let's call the callback. I just felt like the man.
Speaker 1: This listener mail, though, made me realize that we don't
Speaker 1: think other folks all lot. Besides Jerry and like Noelan
Speaker 1: Matt but um, let's do that now, okay, Like Rebecca
Speaker 1: m Rebecca is, uh, what's your official title? I don't
Speaker 1: even know what titles are around producer web producer maybe yeah.
Speaker 1: I mean she handles our website. It makes everything look great.
Speaker 1: And Sherry, even though we do our own social media,
Speaker 1: Sherry does social media for how stuff works, and she
Speaker 1: like throws to us a lot, throws to us and
Speaker 1: helps us out a lot. And Joe, our buddy, Joe
Speaker 1: is a huge help um. And that's kind of the
Speaker 1: crack staff. I mean, we're answering our own emails and
Speaker 1: we're doing a lot of our own stuff. But it
Speaker 1: doesn't mean we don't have help. You know what I'm saying.
Speaker 1: We have tons of help. So you know, I just
Speaker 1: want to say thanks to this. It's very nice if
Speaker 1: you chuck everybody. And I figured six years in, seven
Speaker 1: years in we might as well shout out some of
Speaker 1: our health. Uh. So this from Alex and he said
Speaker 1: to thank anyone else he doesn't know about. And he's
Speaker 1: from Perth, Western Australia, which is nothing like Eastern Australia.
Speaker 1: I'm a nineteen year old aspiring electrician trapped in the
Speaker 1: depths of Western Australia's mining downturn due to layoffs in
Speaker 1: the mining sector, have been unable to find an apprenticeship
Speaker 1: and I would have lost hope if it weren't for you, guys.
Speaker 1: I was just after New Year's It was just after
