WEBVTT - From the Vault: Odds and Evens, Part 3 

0:00:06.240 --> 0:00:08.360
<v Speaker 1>Hey, you welcome to Stuff to Blow your Mind. My

0:00:08.440 --> 0:00:11.000
<v Speaker 1>name is Robert Lamb, and today is Saturday. Once more,

0:00:11.080 --> 0:00:13.640
<v Speaker 1>so we have an episode from the vault. This is

0:00:13.680 --> 0:00:16.680
<v Speaker 1>going to be Odds and Evens, Part three, and it

0:00:16.720 --> 0:00:24.680
<v Speaker 1>originally published nine to twelve, twenty twenty four. Enjoy Welcome

0:00:24.720 --> 0:00:34.160
<v Speaker 1>to Stuff to Blow Your Mind, production of iHeartRadio. Hey,

0:00:34.240 --> 0:00:35.600
<v Speaker 1>welcome to Stuff to Blow your Mind.

0:00:35.680 --> 0:00:38.440
<v Speaker 2>My name is Robert Lamb and I am Joe McCormick,

0:00:38.560 --> 0:00:41.200
<v Speaker 2>and we are back for the third and final part

0:00:41.280 --> 0:00:44.919
<v Speaker 2>in our series on the psychology and cultural significance of

0:00:45.320 --> 0:00:49.920
<v Speaker 2>number paroity pr it y parody referring to whether a

0:00:50.080 --> 0:00:53.159
<v Speaker 2>number is even or odd, and we are ending it

0:00:53.240 --> 0:00:57.200
<v Speaker 2>with an odd number of episodes that just felt right now.

0:00:57.240 --> 0:00:59.000
<v Speaker 2>If you haven't heard the other parts in this series,

0:00:59.040 --> 0:01:00.800
<v Speaker 2>you might want to go back in list into those first.

0:01:00.920 --> 0:01:04.640
<v Speaker 2>But in part one we talked about the mathematical principle

0:01:04.760 --> 0:01:07.640
<v Speaker 2>of number parity, as well as some evidence that people,

0:01:07.760 --> 0:01:13.480
<v Speaker 2>if given the opportunity, will sometimes project associations and emotions

0:01:13.480 --> 0:01:17.960
<v Speaker 2>onto even and odd numbers, for example, by maybe feeling

0:01:18.000 --> 0:01:21.920
<v Speaker 2>more positivity toward even numbers on average, or by having

0:01:22.000 --> 0:01:25.680
<v Speaker 2>an esthetic preference for odd numbers in visual art, as

0:01:25.720 --> 0:01:29.200
<v Speaker 2>reflected in the conventional rule of thirds and rule of

0:01:29.280 --> 0:01:32.480
<v Speaker 2>odds in art theory, which we discussed in some detail

0:01:32.520 --> 0:01:34.760
<v Speaker 2>in that episode. But then we also brought in some

0:01:35.080 --> 0:01:38.880
<v Speaker 2>questions and counter evidence about the real world validity and

0:01:38.920 --> 0:01:43.040
<v Speaker 2>alleged universality of these preferences for odds in art. In

0:01:43.080 --> 0:01:45.679
<v Speaker 2>part two of the series, we talked about a research

0:01:45.760 --> 0:01:49.840
<v Speaker 2>paper on the cognitive psychology of number parity, which advanced

0:01:49.840 --> 0:01:52.800
<v Speaker 2>what I thought was a really interesting argument that despite

0:01:52.840 --> 0:01:57.200
<v Speaker 2>the fact that all positive integers are mathematically defined as

0:01:57.240 --> 0:02:01.320
<v Speaker 2>simply odd or even and nothing in between, our brains

0:02:01.400 --> 0:02:05.080
<v Speaker 2>may in practice treat some numbers as more even or

0:02:05.080 --> 0:02:11.000
<v Speaker 2>more odd than others, mentally transforming these definitionally discrete categories

0:02:11.040 --> 0:02:14.280
<v Speaker 2>into a semi smooth gradient. And this could be due

0:02:14.280 --> 0:02:18.600
<v Speaker 2>to multiple factors, involving mathematical properties like the ease of divisibility,

0:02:19.080 --> 0:02:23.079
<v Speaker 2>and also linguistic properties about how easily we process different

0:02:23.120 --> 0:02:26.560
<v Speaker 2>words and their associated concepts. We also talk some more

0:02:26.600 --> 0:02:30.120
<v Speaker 2>about even and odd groupings in visual art, specifically in

0:02:30.160 --> 0:02:33.240
<v Speaker 2>religious images such as that of the ten headed demon

0:02:33.320 --> 0:02:37.280
<v Speaker 2>king Ravina in Hindu mythology, and we also talked about

0:02:37.320 --> 0:02:40.880
<v Speaker 2>preferences for even or odd groupings on food plates. I

0:02:40.919 --> 0:02:44.520
<v Speaker 2>think the conventional wisdom favors odd numbers of food items,

0:02:44.520 --> 0:02:47.760
<v Speaker 2>but the research maybe paints a slightly more complicated picture.

0:02:48.280 --> 0:02:50.200
<v Speaker 1>Yeah, I think in either case, what does what does

0:02:50.240 --> 0:02:56.040
<v Speaker 1>a plate of food and the multi headed incarnation of

0:02:56.040 --> 0:02:58.639
<v Speaker 1>a Hindu god? What do they have in common? It's

0:02:58.680 --> 0:03:03.160
<v Speaker 1>that there are other things involved and how you're ultimately

0:03:03.400 --> 0:03:06.959
<v Speaker 1>going to perceive this image. Either religious iconography is going

0:03:07.000 --> 0:03:10.120
<v Speaker 1>to be trying to relate other concepts to you the viewer,

0:03:10.200 --> 0:03:13.400
<v Speaker 1>the intended audience viewer, and the food imagery is of

0:03:13.440 --> 0:03:16.520
<v Speaker 1>course showing you something that on some level at least

0:03:16.680 --> 0:03:17.560
<v Speaker 1>you want to eat.

0:03:17.919 --> 0:03:21.800
<v Speaker 2>Yeah, exactly. So we're here today to finish off this

0:03:21.880 --> 0:03:25.280
<v Speaker 2>series with a few more things about odd and even topics.

0:03:26.040 --> 0:03:28.200
<v Speaker 2>So I just wanted to mention at the top of

0:03:28.240 --> 0:03:30.760
<v Speaker 2>the episode here a few more interesting ideas I came

0:03:30.800 --> 0:03:35.080
<v Speaker 2>across while reading about events and odds. Previously, we talked

0:03:35.200 --> 0:03:39.480
<v Speaker 2>about some evidence that at least in certain contexts, people

0:03:39.960 --> 0:03:43.880
<v Speaker 2>like some numbers more than others. For example, they may

0:03:43.960 --> 0:03:48.400
<v Speaker 2>have more positive emotional feelings about even numbers, or at

0:03:48.480 --> 0:03:51.360
<v Speaker 2>least about numbers that are easily divisible because one of

0:03:51.360 --> 0:03:55.640
<v Speaker 2>the studies we talked about in Part one apparently found

0:03:55.640 --> 0:03:58.960
<v Speaker 2>that people had more positive feelings toward even numbers and

0:03:59.240 --> 0:04:03.200
<v Speaker 2>numbers to visible five. Coming back to the question of

0:04:03.320 --> 0:04:06.840
<v Speaker 2>certain numbers feeling more even or less odd than they

0:04:06.880 --> 0:04:10.160
<v Speaker 2>really are. So a great example is that twenty five

0:04:10.440 --> 0:04:13.000
<v Speaker 2>is an odd number, but why does it feel like

0:04:13.040 --> 0:04:15.760
<v Speaker 2>an even number? To me? I would say the ease

0:04:15.840 --> 0:04:18.359
<v Speaker 2>of divisibility by the sub base of five is a

0:04:18.360 --> 0:04:21.160
<v Speaker 2>pretty good guess. And this sort of brings me back

0:04:21.200 --> 0:04:24.560
<v Speaker 2>to an idea I first encountered in a couple of

0:04:24.560 --> 0:04:26.760
<v Speaker 2>the articles that we were talking about in Part one

0:04:26.839 --> 0:04:31.279
<v Speaker 2>by a British author named Alex Bellows who writes newspaper

0:04:31.279 --> 0:04:34.520
<v Speaker 2>columns about mathematics and puzzles sometimes, but it also written

0:04:34.520 --> 0:04:37.640
<v Speaker 2>a book addressing some of these topics. And in these

0:04:37.720 --> 0:04:41.479
<v Speaker 2>articles he talked about people's feelings about odd and even numbers,

0:04:41.920 --> 0:04:44.400
<v Speaker 2>and the idea he raises that if it's true that

0:04:44.640 --> 0:04:48.520
<v Speaker 2>people sometimes feel better about even numbers than odd ones,

0:04:48.920 --> 0:04:52.200
<v Speaker 2>what if that sense of liking for even numbers is

0:04:52.279 --> 0:04:57.480
<v Speaker 2>related to the concept of processing fluency. Now, this is

0:04:57.520 --> 0:05:00.840
<v Speaker 2>a psychological concept that has come up the show before.

0:05:01.440 --> 0:05:03.760
<v Speaker 2>The gist of the idea is that a lot of

0:05:03.760 --> 0:05:08.120
<v Speaker 2>the judgments that humans make, from whether we like something

0:05:08.279 --> 0:05:11.440
<v Speaker 2>to whether we trust a piece of information or believe

0:05:11.560 --> 0:05:15.640
<v Speaker 2>something is true, a lot of these judgments are influenced

0:05:15.720 --> 0:05:20.400
<v Speaker 2>by our subconscious reaction to how easy it is for

0:05:20.480 --> 0:05:25.279
<v Speaker 2>us to mentally process the stimulus in question. There are

0:05:25.320 --> 0:05:27.760
<v Speaker 2>a lot of studies looking at this. I remember this

0:05:27.839 --> 0:05:31.839
<v Speaker 2>came up when we were discussing the illusory truth effect,

0:05:31.960 --> 0:05:36.920
<v Speaker 2>the idea that if a claim a claim may have

0:05:37.000 --> 0:05:39.240
<v Speaker 2>no real evidence for it, or you may have no

0:05:39.360 --> 0:05:42.880
<v Speaker 2>particular reason for believing a claim is true, but if

0:05:42.920 --> 0:05:45.760
<v Speaker 2>you hear it repeated a bunch of times, it starts

0:05:45.800 --> 0:05:48.800
<v Speaker 2>to feel more and more true to you. And one

0:05:48.800 --> 0:05:52.039
<v Speaker 2>of the popular explanations for this effect is the idea

0:05:52.080 --> 0:05:57.800
<v Speaker 2>that hearing a hearing a claim on subsequent exposures increases

0:05:57.880 --> 0:06:00.960
<v Speaker 2>its process in fluency because it's more a miliar to you.

0:06:00.960 --> 0:06:04.159
<v Speaker 2>You've heard it before, so it's easier to take in

0:06:04.200 --> 0:06:06.680
<v Speaker 2>the second, third, fourth, fifth time you hear it, and

0:06:06.720 --> 0:06:10.599
<v Speaker 2>thus it because it has increased processing fluency, it just

0:06:10.720 --> 0:06:13.719
<v Speaker 2>feels more right, It feels more true. One of the

0:06:13.760 --> 0:06:15.600
<v Speaker 2>key findings that already came up in some of the

0:06:15.640 --> 0:06:18.400
<v Speaker 2>papers we talked about in Part two is that it

0:06:18.480 --> 0:06:22.840
<v Speaker 2>seems even numbers are on average more easily processed than

0:06:22.920 --> 0:06:25.800
<v Speaker 2>odd numbers are. You know, when it's easier to think

0:06:25.839 --> 0:06:29.440
<v Speaker 2>about even numbers, we can more quickly classify them mathematically

0:06:29.560 --> 0:06:32.720
<v Speaker 2>as even numbers, it's easier to think about doing mathematical

0:06:32.760 --> 0:06:37.480
<v Speaker 2>operations with them. Odd numbers are just they're introducing friction

0:06:37.640 --> 0:06:40.200
<v Speaker 2>to your brain when you have to consider them. And

0:06:40.360 --> 0:06:42.279
<v Speaker 2>if this is the case, it could be a major

0:06:42.320 --> 0:06:46.359
<v Speaker 2>contributor to these particular situations where people seem to like

0:06:46.560 --> 0:06:50.039
<v Speaker 2>even numbers better than odd numbers. But of course we

0:06:50.120 --> 0:06:52.960
<v Speaker 2>don't always like even numbers better than odd numbers. And

0:06:53.360 --> 0:06:56.599
<v Speaker 2>this comes back to the issues of these additional bits

0:06:56.680 --> 0:07:02.159
<v Speaker 2>of context and cultural associations happen to pin onto these numbers,

0:07:02.400 --> 0:07:04.839
<v Speaker 2>and whether at the time of us having a feeling

0:07:04.839 --> 0:07:07.039
<v Speaker 2>about a number or making a judgment about it, these

0:07:07.120 --> 0:07:11.480
<v Speaker 2>other associations become salient. So anyway, that brings me to

0:07:11.680 --> 0:07:14.840
<v Speaker 2>another line of research that I stumbled across when looking

0:07:14.880 --> 0:07:17.680
<v Speaker 2>into this, that I thought was curious and sort of

0:07:17.720 --> 0:07:23.880
<v Speaker 2>funny also, which is the apparent association between number parity

0:07:24.320 --> 0:07:28.840
<v Speaker 2>and the social concept of gender. Now in much the

0:07:28.880 --> 0:07:32.360
<v Speaker 2>same way, it seems absurd that without any context, in

0:07:32.400 --> 0:07:36.440
<v Speaker 2>other words, without quantifying anything in particular, specific numbers whatever

0:07:36.480 --> 0:07:39.880
<v Speaker 2>feel good or bad to people. It also seems kind

0:07:39.920 --> 0:07:43.480
<v Speaker 2>of absurd that anyone would think of standard Arabic numerals

0:07:43.520 --> 0:07:47.880
<v Speaker 2>as masculine or feminine. But there are some experiments in

0:07:48.440 --> 0:07:52.000
<v Speaker 2>which researchers claim to have found that in some contexts

0:07:52.040 --> 0:07:56.240
<v Speaker 2>there is a pattern of gendered associations between odd and

0:07:56.320 --> 0:07:57.800
<v Speaker 2>even numbers that emerge.

0:07:58.320 --> 0:08:01.360
<v Speaker 1>This is interesting because I I was thinking about gender

0:08:01.760 --> 0:08:05.800
<v Speaker 1>numbers earlier in the research process for this series, because

0:08:05.920 --> 0:08:08.600
<v Speaker 1>I ran across an interesting skit about the number one

0:08:08.640 --> 0:08:09.520
<v Speaker 1>on Sesame Street.

0:08:10.120 --> 0:08:11.480
<v Speaker 2>Oh care to elaborate?

0:08:11.760 --> 0:08:14.120
<v Speaker 1>Oh sure, sure, So in this sketch, this is from

0:08:14.240 --> 0:08:16.080
<v Speaker 1>nineteen ninety seven, so this is not one that I

0:08:16.120 --> 0:08:18.880
<v Speaker 1>was originally exposed to as a kid. But we have

0:08:19.080 --> 0:08:22.160
<v Speaker 1>number one, which is of course a muppet. It is

0:08:22.320 --> 0:08:26.320
<v Speaker 1>the numeral one, and it is a she. So the

0:08:26.720 --> 0:08:30.800
<v Speaker 1>number one she is feeling really down about herself because

0:08:30.800 --> 0:08:34.080
<v Speaker 1>she is such a low value number, like you know,

0:08:34.120 --> 0:08:36.719
<v Speaker 1>it's just she's it's one and then zero, like all

0:08:36.760 --> 0:08:41.440
<v Speaker 1>the other numbers are more potent than her, more important

0:08:41.520 --> 0:08:43.880
<v Speaker 1>than her, and she feels she's really feeling down in

0:08:43.880 --> 0:08:46.240
<v Speaker 1>the dumps about it. Well, who comes up to cheer

0:08:46.240 --> 0:08:50.319
<v Speaker 1>her up? But the Count? Oh, And the Count proceeds

0:08:50.360 --> 0:08:54.400
<v Speaker 1>to sing an entire song for her about how important

0:08:54.440 --> 0:08:57.719
<v Speaker 1>she is numerically, and then afterwards he's like, do you

0:08:57.760 --> 0:09:00.360
<v Speaker 1>feel better? And she's like, well a little bit, and

0:09:00.360 --> 0:09:01.920
<v Speaker 1>he says, well, I'm going to sing it for you

0:09:02.240 --> 0:09:06.679
<v Speaker 1>one more time. But it got me think. It's like, well,

0:09:06.720 --> 0:09:10.600
<v Speaker 1>you know, I didn't think about one being male female,

0:09:10.679 --> 0:09:12.960
<v Speaker 1>what have you? I didn't think about the gender of

0:09:13.000 --> 0:09:16.520
<v Speaker 1>the number one. I just considered it like a number.

0:09:17.200 --> 0:09:19.200
<v Speaker 1>But now I'm thinking of it. I just can't help

0:09:19.240 --> 0:09:21.840
<v Speaker 1>but picture it with like the big full lips and

0:09:21.880 --> 0:09:24.440
<v Speaker 1>the beauty mark here from this nineteen ninety seven Sesame

0:09:24.480 --> 0:09:25.120
<v Speaker 1>Street sketch.

0:09:25.480 --> 0:09:27.960
<v Speaker 2>Well, that is adorable. I like the Count. I hope

0:09:27.960 --> 0:09:30.720
<v Speaker 2>that the Count can help any number feel better about itself.

0:09:30.840 --> 0:09:34.080
<v Speaker 2>All numbers are important, but one is really special.

0:09:34.240 --> 0:09:35.840
<v Speaker 1>Yeah. I think the Count is going to be the

0:09:35.840 --> 0:09:38.960
<v Speaker 1>biggest fan, the biggest supporter of any number. He's not

0:09:38.960 --> 0:09:41.640
<v Speaker 1>going to pull a Harry Neilson and talk about how

0:09:42.040 --> 0:09:44.120
<v Speaker 1>crappy the number one is and how number two is

0:09:44.160 --> 0:09:47.239
<v Speaker 1>also no good. He's a big fan of all of them.

0:09:48.080 --> 0:09:50.199
<v Speaker 2>I like knowing you can count on the count for

0:09:50.280 --> 0:09:54.560
<v Speaker 2>emotional support, so anyway to mention A couple of these

0:09:54.600 --> 0:09:59.920
<v Speaker 2>studies apparently finding this association between gender and number parody.

0:10:01.120 --> 0:10:03.240
<v Speaker 2>A couple of the ones I came across were by

0:10:03.320 --> 0:10:06.839
<v Speaker 2>a pair of researchers named Wilkie and Bodenhausen. One of

0:10:06.880 --> 0:10:09.400
<v Speaker 2>these papers was from twenty twelve in the Journal of

0:10:09.440 --> 0:10:13.240
<v Speaker 2>Experimental Psychology, another one by the same authors from twenty

0:10:13.320 --> 0:10:18.240
<v Speaker 2>fifteen in Frontiers in Psychology, and these papers published the

0:10:18.280 --> 0:10:22.160
<v Speaker 2>results of a number of different experiments about the gender

0:10:22.200 --> 0:10:25.640
<v Speaker 2>associations of odd and even numbers. Now, some of these

0:10:25.760 --> 0:10:30.520
<v Speaker 2>experiments involved explicit judgments, just asking people straight up whether

0:10:30.600 --> 0:10:34.400
<v Speaker 2>they felt like specific numbers were more masculine or feminine,

0:10:34.760 --> 0:10:39.360
<v Speaker 2>and other experiments looked for indirect associations, like people's tendency

0:10:39.480 --> 0:10:43.840
<v Speaker 2>to interpret the faces of babies or unfamiliar foreign names

0:10:44.240 --> 0:10:48.000
<v Speaker 2>with different genders when they were labeled with different numbers.

0:10:48.480 --> 0:10:52.200
<v Speaker 2>And to note that this indirect measure here does rely

0:10:52.360 --> 0:10:56.360
<v Speaker 2>on implicit association tests, which have been subjected to various

0:10:56.400 --> 0:11:01.000
<v Speaker 2>methodological critiques over the years. They've undergone some refinements over

0:11:01.040 --> 0:11:04.240
<v Speaker 2>time to try to improve reliability. But there's still sort

0:11:04.240 --> 0:11:07.280
<v Speaker 2>of debates about how they can be depended on and

0:11:07.320 --> 0:11:10.520
<v Speaker 2>in what context. So anyway, caution on relying too much

0:11:10.520 --> 0:11:13.439
<v Speaker 2>on the implicit parts of these findings. But the authors

0:11:13.440 --> 0:11:16.920
<v Speaker 2>say from the totality of their experiments that on average,

0:11:17.080 --> 0:11:21.080
<v Speaker 2>for some reason, people from sample groups within the United

0:11:21.120 --> 0:11:25.360
<v Speaker 2>States are more likely to say that odd numbers are

0:11:25.440 --> 0:11:29.800
<v Speaker 2>masculine and even numbers are feminine. And while that's the

0:11:29.880 --> 0:11:33.240
<v Speaker 2>general trend, there are some exceptions and caveats. While they

0:11:33.240 --> 0:11:36.160
<v Speaker 2>say that this pattern was on average true for everyone,

0:11:36.280 --> 0:11:40.520
<v Speaker 2>the association was stronger among women, So on average, women

0:11:40.559 --> 0:11:43.720
<v Speaker 2>were more likely to view odd numbers as more masculine

0:11:43.760 --> 0:11:48.360
<v Speaker 2>and less feminine than even numbers. Weirdly, this is where

0:11:48.360 --> 0:11:51.600
<v Speaker 2>it starts getting funny. I thought the numbers in when

0:11:51.600 --> 0:11:54.760
<v Speaker 2>the numbers involved were two digit instead of one digit,

0:11:55.200 --> 0:11:59.760
<v Speaker 2>men started to drift away from this parody association and

0:12:00.040 --> 0:12:03.720
<v Speaker 2>started to say that all numbers were masculine, regardless of parody.

0:12:05.520 --> 0:12:07.800
<v Speaker 2>So I don't whenever we look at studies like this,

0:12:07.920 --> 0:12:10.400
<v Speaker 2>By the way, I always like raise caution because I

0:12:10.480 --> 0:12:12.880
<v Speaker 2>just know from experience a lot of people get real

0:12:12.960 --> 0:12:18.319
<v Speaker 2>excited about like gender differences in responses to psychological experiments

0:12:18.360 --> 0:12:21.760
<v Speaker 2>and then start overinterpreting, thinking it explains everything about men

0:12:21.800 --> 0:12:24.200
<v Speaker 2>and women. Oh, you know why my husband or my

0:12:24.240 --> 0:12:26.760
<v Speaker 2>wife acts a certain way, et cetera. And so I

0:12:26.760 --> 0:12:29.000
<v Speaker 2>will raise the same caution here. You know, it's just

0:12:29.080 --> 0:12:31.080
<v Speaker 2>a few experiments. We're not sure if this is a

0:12:31.080 --> 0:12:34.240
<v Speaker 2>super robust finding, and even if it is robust, it's

0:12:34.240 --> 0:12:36.280
<v Speaker 2>easy to get carried away just reading too much into

0:12:36.320 --> 0:12:40.840
<v Speaker 2>little psychological quirks like this. However, I could not resist

0:12:40.880 --> 0:12:44.400
<v Speaker 2>finding it hilarious to imagine a guy looking at numbers

0:12:44.480 --> 0:12:47.960
<v Speaker 2>higher than nine and being like, thirty four. Huh, that's

0:12:47.960 --> 0:12:50.000
<v Speaker 2>a big number. That's a macho man.

0:12:50.880 --> 0:12:52.880
<v Speaker 1>In between thoughts about ancient real right.

0:12:53.160 --> 0:12:56.320
<v Speaker 2>Yeah, so in reality it's probably not that simple, but

0:12:56.400 --> 0:13:00.880
<v Speaker 2>I was laughing for several minutes after I read this. Anyway,

0:13:01.080 --> 0:13:03.640
<v Speaker 2>the authors of these studies, so they're making an argument

0:13:04.200 --> 0:13:09.360
<v Speaker 2>not that there actually is something objectively or universally gendered

0:13:09.480 --> 0:13:12.400
<v Speaker 2>about even and odd numbers, and instead they're sort of

0:13:12.440 --> 0:13:15.839
<v Speaker 2>making a case about what they call, quote, the pervasiveness

0:13:15.880 --> 0:13:19.960
<v Speaker 2>of gender as a social scaffolding for generating understandings of

0:13:20.040 --> 0:13:23.559
<v Speaker 2>abstract concepts. So the way I take that is they're

0:13:23.600 --> 0:13:26.839
<v Speaker 2>sort of saying gender is such an important concept to

0:13:26.960 --> 0:13:31.520
<v Speaker 2>people that we subconsciously apply it to categories of objects

0:13:31.520 --> 0:13:34.840
<v Speaker 2>that have nothing to do with the primary understanding of

0:13:34.880 --> 0:13:39.040
<v Speaker 2>masculinity or femininity. It's just like a major way of

0:13:39.160 --> 0:13:42.280
<v Speaker 2>making category distinctions that the brain kind of defaults to,

0:13:42.440 --> 0:13:45.559
<v Speaker 2>even in situations that don't have anything to do with

0:13:46.920 --> 0:13:49.400
<v Speaker 2>biological sex or with the social roles of gender.

0:13:50.080 --> 0:13:53.319
<v Speaker 1>Right right, So yeah, it wouldn't be like the hypothetical

0:13:53.520 --> 0:13:56.880
<v Speaker 1>male in question is making a conscious effort to think

0:13:56.920 --> 0:14:02.000
<v Speaker 1>about all higher numbers as men. It's a little more

0:14:02.000 --> 0:14:05.480
<v Speaker 1>new as a little more subconscious than that.

0:14:05.920 --> 0:14:09.040
<v Speaker 2>Now I mentioned that those studies were done on us

0:14:09.080 --> 0:14:12.400
<v Speaker 2>test subjects. I came across an interesting variation with respect

0:14:12.440 --> 0:14:16.120
<v Speaker 2>to culture. So there was a twenty twenty one study

0:14:16.200 --> 0:14:20.760
<v Speaker 2>in Frontiers and Psychology by Jordan Yakani and Sheen which

0:14:20.840 --> 0:14:25.480
<v Speaker 2>found some consistency and some variation across cultures regarding the

0:14:25.840 --> 0:14:30.640
<v Speaker 2>perceived gender of numbers. These researchers tested whether the same

0:14:30.720 --> 0:14:34.400
<v Speaker 2>patterns of association between number parity and gender would show

0:14:34.480 --> 0:14:38.560
<v Speaker 2>up among Arabic speaking people native to the UAE, and

0:14:38.600 --> 0:14:41.960
<v Speaker 2>their top level findings were that there were patterns of

0:14:42.000 --> 0:14:46.840
<v Speaker 2>gender association with number parity, but on the implicit association

0:14:46.920 --> 0:14:50.080
<v Speaker 2>of numbers with faces, the subjects in the UAE were

0:14:50.120 --> 0:14:54.480
<v Speaker 2>more likely to associate even numbers with their own gender,

0:14:54.680 --> 0:14:59.280
<v Speaker 2>whichever that was so, men seeing even numbers as more masculine,

0:14:59.320 --> 0:15:03.400
<v Speaker 2>women seeing even numbers as more feminine. And these findings

0:15:03.440 --> 0:15:08.600
<v Speaker 2>indicate that it may be cross culturally common to associate

0:15:08.720 --> 0:15:11.160
<v Speaker 2>even in odd numbers with gender, at least in some

0:15:11.240 --> 0:15:13.720
<v Speaker 2>weekly held way, to make some kind of weak association

0:15:13.840 --> 0:15:18.040
<v Speaker 2>of that kind, but that the association can vary from

0:15:18.080 --> 0:15:20.840
<v Speaker 2>culture to culture, which actually makes a lot of sense

0:15:20.880 --> 0:15:23.400
<v Speaker 2>to me that I think the idea would sort of

0:15:23.440 --> 0:15:27.240
<v Speaker 2>be that gender is a category lens that we're very

0:15:27.320 --> 0:15:30.800
<v Speaker 2>quick to apply to all kinds of phenomena outside of

0:15:30.800 --> 0:15:35.120
<v Speaker 2>its primary cultural meaning, but exactly how we apply it

0:15:35.160 --> 0:15:38.800
<v Speaker 2>probably depends on a lot of subtle influences that can

0:15:38.800 --> 0:15:42.200
<v Speaker 2>easily vary person to person and culture to culture, though

0:15:42.200 --> 0:15:45.640
<v Speaker 2>apparently within a given language culture, one way of making

0:15:45.720 --> 0:15:49.800
<v Speaker 2>the association is probably more common than another. So anyway,

0:15:49.840 --> 0:15:52.280
<v Speaker 2>all the warnings I gave up top about not reading

0:15:52.320 --> 0:15:54.280
<v Speaker 2>too much into these kinds of findings, but I do

0:15:54.320 --> 0:15:57.680
<v Speaker 2>think if this is basically on the right track, it's

0:15:57.720 --> 0:16:00.760
<v Speaker 2>an interesting example of the way that we we just

0:16:00.880 --> 0:16:05.840
<v Speaker 2>kind of recklessly apply category distinctions across every domain of life,

0:16:05.880 --> 0:16:09.960
<v Speaker 2>whether it really makes direct sense or not. You know,

0:16:10.040 --> 0:16:12.120
<v Speaker 2>I think we if we ever talked about the idea

0:16:12.120 --> 0:16:13.840
<v Speaker 2>on the show before, some people seem to think like

0:16:13.960 --> 0:16:15.680
<v Speaker 2>dogs or boys, cats or girls.

0:16:16.080 --> 0:16:19.920
<v Speaker 1>Yeah. I have caught myself falling into that trap as well,

0:16:19.960 --> 0:16:22.840
<v Speaker 1>Like I kind of on a default level assume cats

0:16:22.840 --> 0:16:26.360
<v Speaker 1>are girls and dogs are boys until I know differently

0:16:26.360 --> 0:16:29.960
<v Speaker 1>concerning individual cats and dogs, and I don't know. One

0:16:30.000 --> 0:16:32.160
<v Speaker 1>reason for that is probably that I've only ever had cats,

0:16:32.240 --> 0:16:34.680
<v Speaker 1>and those cats have always been girls. I don't know, yeah,

0:16:34.760 --> 0:16:38.600
<v Speaker 1>female cats. Sorry, some of them have been very old ladies.

0:16:39.000 --> 0:16:42.040
<v Speaker 2>Then again, at least cats and dogs are like animals.

0:16:43.520 --> 0:16:45.960
<v Speaker 2>You know. It's I guess it's even funnier thinking about

0:16:45.960 --> 0:16:50.080
<v Speaker 2>the way that we we just wantonly apply these categories,

0:16:50.240 --> 0:16:55.280
<v Speaker 2>possibly even to things like abstract numbers and symbols that

0:16:54.800 --> 0:16:57.920
<v Speaker 2>that don't even have like you know, bodies or minds

0:16:58.040 --> 0:17:00.200
<v Speaker 2>or anything. Yeah.

0:17:00.240 --> 0:17:02.320
<v Speaker 1>The only the other prime example that comes to mind

0:17:02.400 --> 0:17:05.800
<v Speaker 1>is when especially a ship but sometimes other vehicles or

0:17:06.160 --> 0:17:07.080
<v Speaker 1>gendered as female.

0:17:07.400 --> 0:17:09.920
<v Speaker 2>Yeah, that always seemed funny to me.

0:17:20.160 --> 0:17:22.760
<v Speaker 1>All right, Now for this next little bit, I wanted

0:17:22.800 --> 0:17:26.119
<v Speaker 1>to talk briefly about the word odd. I was looking

0:17:26.160 --> 0:17:28.000
<v Speaker 1>at other angles on odd and even, and I came

0:17:28.040 --> 0:17:31.639
<v Speaker 1>across this excellent write up on Websters, and it points

0:17:31.680 --> 0:17:35.240
<v Speaker 1>out that the word in English comes from the Old

0:17:35.359 --> 0:17:41.000
<v Speaker 1>Norse word audie odd i, meaning point of land in

0:17:41.040 --> 0:17:45.719
<v Speaker 1>the geographical sense. So it's like the point of a triangle,

0:17:45.960 --> 0:17:49.399
<v Speaker 1>and so it eventually came to mean triangle, and it

0:17:49.440 --> 0:17:52.359
<v Speaker 1>also came to mean odd, as the point of a

0:17:52.400 --> 0:17:56.280
<v Speaker 1>triangle triangle must always oppose the two other corners, so

0:17:56.320 --> 0:17:58.800
<v Speaker 1>it's like the two other corners are an even pair,

0:17:59.600 --> 0:18:02.720
<v Speaker 1>and if they were to leave, then the audi is alone.

0:18:02.840 --> 0:18:06.720
<v Speaker 2>Wow, that's almost poetic. That's like a beautiful etymology.

0:18:06.960 --> 0:18:10.480
<v Speaker 1>Yeah. And eventually from here the term transfers over into English,

0:18:10.800 --> 0:18:14.000
<v Speaker 1>and by the fourteenth century it was written down, so

0:18:14.119 --> 0:18:15.680
<v Speaker 1>you know, it may have made the journey. It probably

0:18:15.680 --> 0:18:17.480
<v Speaker 1>it definitely made the journey earlier than that, but that's

0:18:17.520 --> 0:18:20.800
<v Speaker 1>when we have written evidence of it. And initially the

0:18:20.840 --> 0:18:25.480
<v Speaker 1>word odd meant without a corresponding mate, so it was

0:18:25.480 --> 0:18:28.960
<v Speaker 1>still like tied up with this idea of like to

0:18:29.080 --> 0:18:31.199
<v Speaker 1>leave and leave one. But then it comes to mean

0:18:31.240 --> 0:18:35.639
<v Speaker 1>irregular or non conformist, and Webster's notes that during the

0:18:35.680 --> 0:18:39.439
<v Speaker 1>fifteenth and sixteenth centuries, this usage of odd in English

0:18:39.520 --> 0:18:41.880
<v Speaker 1>language was a good thing. It meant you stood out,

0:18:41.960 --> 0:18:44.400
<v Speaker 1>you know. It's like, oh, look at that odd character there,

0:18:44.520 --> 0:18:46.160
<v Speaker 1>We've got to go chat him up. He has lots

0:18:46.160 --> 0:18:48.639
<v Speaker 1>of interesting things to say as he drinketh from his

0:18:48.680 --> 0:18:52.679
<v Speaker 1>skull and walketh is bear. But then by the seventeenth

0:18:52.720 --> 0:18:56.879
<v Speaker 1>century it comes to lean more toward the eccentric and

0:18:56.920 --> 0:18:59.679
<v Speaker 1>even dare we say, the weird, in the sense that

0:18:59.680 --> 0:19:02.640
<v Speaker 1>you might be like, let's stay away from the guy

0:19:02.680 --> 0:19:05.080
<v Speaker 1>with the bear and the skull. Lord knows what he's

0:19:05.119 --> 0:19:09.240
<v Speaker 1>going to talk about. Let's keep a distance. Wow.

0:19:09.240 --> 0:19:11.760
<v Speaker 2>It almost invokes like a story in the sense that

0:19:11.840 --> 0:19:14.000
<v Speaker 2>if you imagine there were three people and two of

0:19:14.040 --> 0:19:17.040
<v Speaker 2>them left, and now one is odd. Why did the

0:19:17.080 --> 0:19:21.680
<v Speaker 2>other two leave? Were they driven away by the behavior

0:19:21.720 --> 0:19:24.159
<v Speaker 2>of the first one? Or could they just not handle

0:19:24.200 --> 0:19:24.840
<v Speaker 2>the genius?

0:19:25.320 --> 0:19:29.280
<v Speaker 1>Yes, and my apologies to Lord Byron Fans, since he's

0:19:29.640 --> 0:19:33.640
<v Speaker 1>barely covered in the centuries reference there. But Webster's also

0:19:33.640 --> 0:19:36.040
<v Speaker 1>points out that the use of the noun odd for

0:19:36.119 --> 0:19:38.480
<v Speaker 1>a point of land seems to have crossed over a

0:19:38.640 --> 0:19:43.720
<v Speaker 1>second time into English during the nineteenth century, though more

0:19:43.720 --> 0:19:47.280
<v Speaker 1>exclusively to northern England and Scotland. Oh and one more

0:19:47.320 --> 0:19:50.280
<v Speaker 1>little bit here that I ran across. Audi is also

0:19:50.320 --> 0:19:54.800
<v Speaker 1>the name of a town in Iceland. And well, I'm

0:19:54.800 --> 0:19:58.120
<v Speaker 1>not as sure about the direct linguistic connection here between

0:19:58.160 --> 0:20:00.400
<v Speaker 1>what we're talking about and the name of the town

0:20:00.720 --> 0:20:04.200
<v Speaker 1>I did run across. The picture of a statue of

0:20:05.000 --> 0:20:08.679
<v Speaker 1>Salmon the Wise hitting the Devil, and the devil may

0:20:08.760 --> 0:20:10.280
<v Speaker 1>or may not be in the form of a seal

0:20:10.320 --> 0:20:14.679
<v Speaker 1>here with a bible. This was I found this a

0:20:14.720 --> 0:20:16.760
<v Speaker 1>photograph of this on a blog post by eric O

0:20:16.880 --> 0:20:20.320
<v Speaker 1>Scott on the website The Wild Hunt. And this ties

0:20:20.359 --> 0:20:24.320
<v Speaker 1>into a past episode because in our series on Shadows

0:20:24.320 --> 0:20:28.560
<v Speaker 1>from last October that is going to re air this October,

0:20:28.720 --> 0:20:30.760
<v Speaker 1>we talked a little bit about the shadow wizard and

0:20:30.840 --> 0:20:36.680
<v Speaker 1>priest semond or Semonder, the Wise, who has various encounters

0:20:36.680 --> 0:20:38.920
<v Speaker 1>with the Devil. I don't think we talked about him

0:20:38.960 --> 0:20:41.480
<v Speaker 1>hitting the devil with a Bible, but there is an

0:20:41.480 --> 0:20:44.560
<v Speaker 1>episode where he ends up having his shadow stolen by

0:20:44.560 --> 0:20:45.000
<v Speaker 1>the devil.

0:20:45.520 --> 0:20:48.200
<v Speaker 2>Right doesn't he go to like the Devil's College or

0:20:48.240 --> 0:20:51.680
<v Speaker 2>the Devil's School to learn the learn the magical arts.

0:20:51.680 --> 0:20:53.879
<v Speaker 2>But then the devil is supposed to grab one of

0:20:53.920 --> 0:20:56.240
<v Speaker 2>the students at the end of the semester and keep them.

0:20:56.760 --> 0:21:00.560
<v Speaker 2>But semen, they're various tellings, but semen find some way

0:21:00.600 --> 0:21:02.159
<v Speaker 2>to kind of trick the devil and escape.

0:21:02.400 --> 0:21:04.680
<v Speaker 1>Yeah. Yeah, and he like goes to snatch his soul

0:21:04.840 --> 0:21:07.480
<v Speaker 1>and gets his shadow instead and so forth. So I

0:21:07.520 --> 0:21:11.040
<v Speaker 1>don't know, I'm drifting drifting off topic here, but we're

0:21:11.119 --> 0:21:16.399
<v Speaker 1>still somewhere in the neighborhood of a lot and even now. Next,

0:21:16.480 --> 0:21:19.560
<v Speaker 1>I would like to turn to evens and odds and biology.

0:21:19.920 --> 0:21:24.040
<v Speaker 1>This is an area that, uh where you can you know,

0:21:24.240 --> 0:21:26.040
<v Speaker 1>I guess with any of this you have to, especially

0:21:26.040 --> 0:21:27.720
<v Speaker 1>when you're playing in to biology, you have to think

0:21:27.720 --> 0:21:31.399
<v Speaker 1>about like the relationship between numbers and reality, and you

0:21:31.400 --> 0:21:33.160
<v Speaker 1>can get, you know, kind of go do a fair

0:21:33.160 --> 0:21:35.480
<v Speaker 1>amount of navel gazing on that in and of itself.

0:21:36.000 --> 0:21:38.280
<v Speaker 1>But you know, just as we see a tendency for

0:21:38.440 --> 0:21:43.199
<v Speaker 1>external symmetry and biological organisms, we at least to some extent,

0:21:43.480 --> 0:21:48.200
<v Speaker 1>see a tendency toward even numbers. Again, huge caveat here.

0:21:48.280 --> 0:21:50.440
<v Speaker 1>It kind of it can also depend on exactly how

0:21:50.480 --> 0:21:52.239
<v Speaker 1>you want to cut it, because you know, you can

0:21:52.240 --> 0:21:55.320
<v Speaker 1>take a quick survey of your own body, and chances

0:21:55.359 --> 0:21:58.159
<v Speaker 1>are you're going to find some even numbers in play.

0:21:58.280 --> 0:22:03.560
<v Speaker 1>You know, two arms, to let, four limbs total, ten fingers,

0:22:03.600 --> 0:22:07.080
<v Speaker 1>ten toes, two eyes, two nostrils, and so forth. On

0:22:07.119 --> 0:22:09.080
<v Speaker 1>the other hand, I mean, yes, you do have one

0:22:09.119 --> 0:22:12.399
<v Speaker 1>mouth and so forth. But you know, the still of

0:22:12.440 --> 0:22:15.440
<v Speaker 1>course lines up with the basic idea of bilateral symmetry.

0:22:15.600 --> 0:22:17.880
<v Speaker 1>Divide a creature down the middle and you have two

0:22:18.040 --> 0:22:21.320
<v Speaker 1>equal sides, though of course we also have to throw

0:22:21.359 --> 0:22:23.439
<v Speaker 1>in the other caveat that the average human being is

0:22:23.480 --> 0:22:27.400
<v Speaker 1>not perfectly symmetrical, and artificially symmetrical faces tend to read

0:22:27.400 --> 0:22:28.680
<v Speaker 1>as uncanny to us.

0:22:28.720 --> 0:22:32.879
<v Speaker 2>For this reason, we actually did a series on biological

0:22:32.920 --> 0:22:36.720
<v Speaker 2>symmetry and asymmetry a couple of years back. I don't

0:22:36.880 --> 0:22:39.240
<v Speaker 2>recall it was that the series called The Lesser of

0:22:39.240 --> 0:22:40.640
<v Speaker 2>Two crab Claws, where.

0:22:40.560 --> 0:22:44.119
<v Speaker 1>I think the fiddler crabs mm hm, yes, Because you know,

0:22:44.200 --> 0:22:46.480
<v Speaker 1>there are plenty of examples too in the biological world

0:22:46.480 --> 0:22:48.640
<v Speaker 1>which we get into in that series, where there is

0:22:48.760 --> 0:22:52.080
<v Speaker 1>a glaring asymmetry. So anyway, it would be a gross mistake. Though,

0:22:52.320 --> 0:22:54.000
<v Speaker 1>coming back to odds and evens, if you were to

0:22:54.040 --> 0:22:56.720
<v Speaker 1>say that you only see even numbers and organisms. That

0:22:57.000 --> 0:23:00.000
<v Speaker 1>is absolutely not true, and they're ultimately far more common

0:23:00.040 --> 0:23:04.000
<v Speaker 1>place and satisfying ways to apply numbers more universally to nature,

0:23:04.080 --> 0:23:07.360
<v Speaker 1>such as say the Fibonacci sequence so forth. But it's

0:23:07.359 --> 0:23:10.080
<v Speaker 1>still interesting to see cases where there is that there

0:23:10.119 --> 0:23:14.240
<v Speaker 1>seems to be a tendency toward even numbers, and still

0:23:14.320 --> 0:23:19.240
<v Speaker 1>looking at the exceptions to those possible rules and possible tendencies.

0:23:19.400 --> 0:23:22.680
<v Speaker 1>One place that start is with chromosomes. So a chromosome

0:23:22.880 --> 0:23:25.680
<v Speaker 1>is a DNA package that contains all the genetic material

0:23:25.720 --> 0:23:29.280
<v Speaker 1>of an organism, and the chromosome count for individual species

0:23:29.400 --> 0:23:32.199
<v Speaker 1>varies greatly, and it has nothing to do with it

0:23:32.240 --> 0:23:35.959
<v Speaker 1>doesn't correlate with the apparent complexity of an organism. So

0:23:36.200 --> 0:23:38.840
<v Speaker 1>you know, for example, a jack jumper and has a

0:23:38.880 --> 0:23:42.720
<v Speaker 1>single pair of chromosomes, while turkey has eighty. A human

0:23:43.160 --> 0:23:46.159
<v Speaker 1>of course has forty six, and then you have a

0:23:46.200 --> 0:23:48.560
<v Speaker 1>case like and to be clear, you can also get

0:23:48.640 --> 0:23:51.760
<v Speaker 1>odd numbers via genetic disorders. But one of the biggest

0:23:51.920 --> 0:23:54.720
<v Speaker 1>examples it's often brought up of an odd number of

0:23:54.800 --> 0:23:58.119
<v Speaker 1>chromosomes in an organism is the mule. This is a

0:23:58.160 --> 0:24:01.159
<v Speaker 1>cross between donkey and a horse of course, and it,

0:24:01.920 --> 0:24:05.280
<v Speaker 1>you know, tends out for having sixty three and they're

0:24:05.400 --> 0:24:09.040
<v Speaker 1>usually infertile because of this. And there's some other interesting

0:24:09.119 --> 0:24:13.159
<v Speaker 1>outliers as well, like the Indian Mutjak, in which males

0:24:13.200 --> 0:24:16.000
<v Speaker 1>tend to have seven to the female six. In the

0:24:16.040 --> 0:24:19.080
<v Speaker 1>swamp Wallaby you see eleven for males and ten for females,

0:24:19.680 --> 0:24:23.199
<v Speaker 1>and there are various other examples of this nature. But

0:24:23.240 --> 0:24:26.000
<v Speaker 1>of course this is all hidden to the naked eye.

0:24:26.200 --> 0:24:28.880
<v Speaker 1>Limbs stand out far more in human consideration when we're

0:24:28.880 --> 0:24:31.760
<v Speaker 1>talking about evens and odds, and so this raises the

0:24:31.840 --> 0:24:36.200
<v Speaker 1>question what if anything naturally has an odd number of arms?

0:24:37.920 --> 0:24:42.280
<v Speaker 1>And basically the answer is nothing except blank. And I'll

0:24:42.280 --> 0:24:44.280
<v Speaker 1>come back to the blank in just a second. But

0:24:44.480 --> 0:24:48.480
<v Speaker 1>there's one potential possibility that often comes up if you're

0:24:48.520 --> 0:24:51.480
<v Speaker 1>just scanning the names of the popular names of organisms,

0:24:51.800 --> 0:24:53.879
<v Speaker 1>and it's one. There's one that came up on a

0:24:53.880 --> 0:24:58.600
<v Speaker 1>Monster Fact episode several weeks back. There is a species

0:24:58.600 --> 0:25:02.040
<v Speaker 1>of octopus known as the seven armed octopus.

0:25:02.680 --> 0:25:05.560
<v Speaker 2>Now that is an oxymoron, isn't it right?

0:25:05.680 --> 0:25:09.600
<v Speaker 1>Right? Because if you know anything about octopi, it is that,

0:25:09.680 --> 0:25:13.200
<v Speaker 1>as the name implies, they have eight arms. So if

0:25:13.240 --> 0:25:16.080
<v Speaker 1>you had a seven armed octopus that that would be interesting.

0:25:16.200 --> 0:25:18.119
<v Speaker 1>Why does it have why does it seem to have

0:25:18.160 --> 0:25:22.359
<v Speaker 1>seven arms? So this octopus is also known as the

0:25:22.800 --> 0:25:30.040
<v Speaker 1>septipus or the blob octopus, and it is Halofron atlanticus.

0:25:30.440 --> 0:25:33.520
<v Speaker 1>And here's the thing, it actually does have eight arms.

0:25:33.720 --> 0:25:38.200
<v Speaker 1>It like, do not believe the popular name. Uh, it's

0:25:38.320 --> 0:25:44.360
<v Speaker 1>just that the males specialized fertilization arm. It's hectocoidalus remains

0:25:44.440 --> 0:25:47.960
<v Speaker 1>coiled away in a sack beneath the right the right eye.

0:25:48.480 --> 0:25:53.520
<v Speaker 1>So this is a specialized arm. In various sephalopods have

0:25:53.600 --> 0:25:56.400
<v Speaker 1>these and there it's the kind of arm that will

0:25:56.440 --> 0:25:59.200
<v Speaker 1>be used to slip in genetic material or sometimes it

0:25:59.320 --> 0:26:02.760
<v Speaker 1>is like left detached and left with the mate. So

0:26:03.440 --> 0:26:07.560
<v Speaker 1>this species has a specialized arm for mating, and it

0:26:07.640 --> 0:26:10.879
<v Speaker 1>keeps it stored away out of sight behind the right eye.

0:26:11.160 --> 0:26:15.439
<v Speaker 1>And so if you're just checking out the specimen and

0:26:15.600 --> 0:26:17.720
<v Speaker 1>you don't know what to look for, you might see

0:26:17.760 --> 0:26:20.200
<v Speaker 1>only seven arms and assume, well, here we are, it's

0:26:20.240 --> 0:26:23.640
<v Speaker 1>a seven armed octopus. But like I said, there are

0:26:23.720 --> 0:26:27.640
<v Speaker 1>some examples of animals with an odd number of limbs.

0:26:28.440 --> 0:26:30.560
<v Speaker 1>But to find one we have to look to the

0:26:30.600 --> 0:26:34.639
<v Speaker 1>marine invertebrates known as c stars, which tend to boast

0:26:35.280 --> 0:26:38.480
<v Speaker 1>five arms, though they can't have more depending on the species.

0:26:39.040 --> 0:26:42.439
<v Speaker 1>Five arms in a radial presentation. I mean, everyone knows

0:26:42.480 --> 0:26:46.120
<v Speaker 1>what a starfish looks like. You've seen SpongeBob. You get

0:26:46.200 --> 0:26:47.000
<v Speaker 1>the general idea.

0:26:47.600 --> 0:26:50.120
<v Speaker 2>Oh okay, and here's where we get into the different

0:26:50.320 --> 0:26:53.560
<v Speaker 2>types of symmetry that are found in animal body plans. Right.

0:26:53.600 --> 0:26:57.880
<v Speaker 2>Because while most animals, and especially most animals we're familiar with,

0:26:58.440 --> 0:27:01.760
<v Speaker 2>have a bi ladder really symmetrical body plan it can

0:27:01.800 --> 0:27:05.240
<v Speaker 2>be divided down the middle and folded in half, there

0:27:05.280 --> 0:27:08.080
<v Speaker 2>are some animals that live, especially in the ocean, that

0:27:08.119 --> 0:27:11.720
<v Speaker 2>have a radially symmetrical body plan, meaning it can be

0:27:11.800 --> 0:27:15.760
<v Speaker 2>it is symmetrical in that it has copied segments, but

0:27:15.800 --> 0:27:18.760
<v Speaker 2>they are copied by going around in a circle instead

0:27:18.800 --> 0:27:20.240
<v Speaker 2>of folding in half down the middle.

0:27:20.640 --> 0:27:25.000
<v Speaker 1>Yeah. Yeah, And this is a This is especially interesting

0:27:25.040 --> 0:27:28.440
<v Speaker 1>concerning the sea star because this comes back to something

0:27:28.480 --> 0:27:32.800
<v Speaker 1>we talked about perhaps last October as well, that, according

0:27:33.600 --> 0:27:36.439
<v Speaker 1>to some analysis, particularly a twenty twenty three study publishing

0:27:36.480 --> 0:27:40.800
<v Speaker 1>the journal Nature by Formery at All, the c star

0:27:41.160 --> 0:27:45.440
<v Speaker 1>is really more of the head with five or more extensions.

0:27:45.720 --> 0:27:50.520
<v Speaker 1>They're not really arms. They're more like head projections, which

0:27:50.600 --> 0:27:54.800
<v Speaker 1>is an interesting way of looking at it. But another

0:27:54.840 --> 0:27:56.720
<v Speaker 1>thing that they point out in this article is that

0:27:57.080 --> 0:28:00.600
<v Speaker 1>sea stars evolved from an ancestor that add two fold

0:28:00.680 --> 0:28:04.919
<v Speaker 1>or bilateral symmetry, and it develops from larvae that also

0:28:05.040 --> 0:28:10.000
<v Speaker 1>have twofold or bilateral symmetry, but they have a typically

0:28:10.200 --> 0:28:15.560
<v Speaker 1>you know, fivefold radial adult body plan. So yeah, another

0:28:15.600 --> 0:28:29.400
<v Speaker 1>fascinating example. Now, another place to look for even numbers

0:28:29.680 --> 0:28:32.520
<v Speaker 1>in a mammal is, of course, look to the nipples.

0:28:33.000 --> 0:28:35.760
<v Speaker 1>Humans typically have two of these, though to be clear,

0:28:35.800 --> 0:28:37.560
<v Speaker 1>you do have situations where people have, like say, a

0:28:37.560 --> 0:28:41.280
<v Speaker 1>third nipple, but generally speaking you're dealing with a two

0:28:41.360 --> 0:28:45.920
<v Speaker 1>nipple scenario. If you have a cat, you can. I

0:28:45.960 --> 0:28:49.520
<v Speaker 1>don't recommend feeling around because unless you're a professional, because

0:28:49.560 --> 0:28:52.120
<v Speaker 1>you will often get clawed for this. But cats have

0:28:52.240 --> 0:28:56.520
<v Speaker 1>six to eight nipples, and indeed most mammals have an

0:28:56.560 --> 0:29:01.360
<v Speaker 1>even number of nipples. But if you turn to the marsupial,

0:29:01.480 --> 0:29:06.720
<v Speaker 1>the American opossum, you will find a famous outlier here

0:29:07.000 --> 0:29:09.640
<v Speaker 1>with an array of thirteen nipples.

0:29:10.080 --> 0:29:13.840
<v Speaker 2>Now, don't start putting your cultural associations on the opossum.

0:29:13.960 --> 0:29:16.520
<v Speaker 2>No one of its nipples is the unlucky one.

0:29:17.080 --> 0:29:19.800
<v Speaker 1>Now, because when you look at the number of young

0:29:19.840 --> 0:29:22.480
<v Speaker 1>they have like it's it's it's the like the ghost

0:29:22.560 --> 0:29:25.320
<v Speaker 1>nipples past thirteen that were the unlucky ones, because they

0:29:25.360 --> 0:29:27.920
<v Speaker 1>generally have and this is environmentally dependent, they generally have

0:29:27.960 --> 0:29:30.840
<v Speaker 1>like twenty young. So not everybody's gonna get a nipple

0:29:31.160 --> 0:29:35.080
<v Speaker 1>and survive. But but yeah, you can. You can look

0:29:35.120 --> 0:29:41.080
<v Speaker 1>up I don't strongly recommend the opossum nipple google image search,

0:29:41.800 --> 0:29:44.040
<v Speaker 1>but you can. You can find some illustrations that I

0:29:44.040 --> 0:29:48.959
<v Speaker 1>think are ultimately more helpful and better for you, know,

0:29:49.000 --> 0:29:52.560
<v Speaker 1>your sanity, than looking up the actual images of opossom

0:29:52.680 --> 0:29:57.600
<v Speaker 1>nipple arrangements. But the illustrations give you the general idea.

0:29:57.720 --> 0:30:03.160
<v Speaker 1>So I've seen this described as two arches of six nipples,

0:30:03.200 --> 0:30:06.880
<v Speaker 1>with one nipple located centrally. I've also seen it talked

0:30:06.880 --> 0:30:08.800
<v Speaker 1>about in terms of being like a U shape or

0:30:08.840 --> 0:30:14.480
<v Speaker 1>circular shape inside of the female opossum's pouch. Now, there

0:30:14.520 --> 0:30:16.520
<v Speaker 1>are various other classifications of the un and odds we

0:30:16.600 --> 0:30:18.880
<v Speaker 1>might get into there. Of course, odd toed and even

0:30:18.960 --> 0:30:23.960
<v Speaker 1>toed ungulates. Tapers, for example, have four hoofed toes in

0:30:24.000 --> 0:30:27.480
<v Speaker 1>the front and three hoofed toes in the back. Most

0:30:27.560 --> 0:30:32.160
<v Speaker 1>rhino species have three digits on each foot and in general, though,

0:30:32.360 --> 0:30:33.960
<v Speaker 1>and we've gotten into this a bit in the past,

0:30:34.000 --> 0:30:37.800
<v Speaker 1>especially when we talked about horse hoofs, evolution has resulted

0:30:37.920 --> 0:30:42.640
<v Speaker 1>in digit numbers greater and less than the human five

0:30:42.720 --> 0:30:45.400
<v Speaker 1>that we take for granted, you know, because you can

0:30:45.440 --> 0:30:49.080
<v Speaker 1>look at the horse's hoof and see it as a

0:30:49.120 --> 0:30:52.040
<v Speaker 1>single toe, a single great toe foot. And we see

0:30:52.040 --> 0:30:55.640
<v Speaker 1>the opposite as well in some other organisms, with the

0:30:55.680 --> 0:30:59.560
<v Speaker 1>development of a sixth pseudothumb. This is you can find

0:30:59.560 --> 0:31:03.200
<v Speaker 1>these in the giant panda, for example, where this has evolved.

0:31:03.240 --> 0:31:06.600
<v Speaker 1>It's not truly an additional digit on the hand, but

0:31:06.800 --> 0:31:12.040
<v Speaker 1>it is basically like doing the work of an extra

0:31:13.160 --> 0:31:18.240
<v Speaker 1>partially evolved digit to aid in the NonStop consumption of bamboo.

0:31:18.720 --> 0:31:23.440
<v Speaker 1>And then we also see a remarkable pseudo thumb emerge

0:31:23.600 --> 0:31:27.480
<v Speaker 1>on the hand of the II lemur. So the II

0:31:27.680 --> 0:31:30.400
<v Speaker 1>lemur may be a lemur that a number of view

0:31:30.480 --> 0:31:32.800
<v Speaker 1>familiar with from various nature documentaries, because it is a

0:31:32.880 --> 0:31:38.040
<v Speaker 1>very weird, goblin esque looking creature. It's it's it's wonderful,

0:31:38.080 --> 0:31:40.520
<v Speaker 1>I say it is. It is weird. In all of

0:31:40.200 --> 0:31:43.520
<v Speaker 1>the great ways that an animal can be weird. You know,

0:31:43.560 --> 0:31:46.400
<v Speaker 1>it is nocturnal. Uh, it again looks kind of like

0:31:46.440 --> 0:31:49.600
<v Speaker 1>a goblin, and it has these very specialized hands that

0:31:49.680 --> 0:31:53.440
<v Speaker 1>feature a super long middle finger, which it uses. Uh.

0:31:53.600 --> 0:31:56.040
<v Speaker 1>It uses it specialized hands to like cap on wood

0:31:56.280 --> 0:31:58.680
<v Speaker 1>and then uses that that super long middle finger to

0:31:58.800 --> 0:32:03.160
<v Speaker 1>reach in and dig out grubs and wood burrowing insects

0:32:03.200 --> 0:32:03.560
<v Speaker 1>to eat.

0:32:04.120 --> 0:32:07.360
<v Speaker 2>Yeah, so it sort of has nose Feratu hands. But

0:32:07.560 --> 0:32:12.040
<v Speaker 2>I can't emphasize enough that the face in many photos

0:32:12.240 --> 0:32:17.640
<v Speaker 2>is going, oh dude, it's like very big wide eyes

0:32:17.760 --> 0:32:20.680
<v Speaker 2>and the mouth open like it is shouting at you

0:32:20.800 --> 0:32:22.320
<v Speaker 2>in excitement and surprise.

0:32:23.120 --> 0:32:26.160
<v Speaker 1>Yeah. So it's the situation those seems to be pretty

0:32:26.160 --> 0:32:29.160
<v Speaker 1>fascinating here because they have this super specialized again long

0:32:29.200 --> 0:32:32.000
<v Speaker 1>middle finger. It basically has a single use. It's essentially

0:32:32.040 --> 0:32:35.600
<v Speaker 1>a unit tasker. But that means that they need a

0:32:35.600 --> 0:32:37.600
<v Speaker 1>little more help climbing. So it's like, you know, it's

0:32:37.600 --> 0:32:39.720
<v Speaker 1>like they had a callub evolution and say, look, I

0:32:39.760 --> 0:32:42.560
<v Speaker 1>need to put an order in for an extra digit.

0:32:43.680 --> 0:32:47.680
<v Speaker 1>Why you already have five digits. Well, yes, but I've

0:32:47.720 --> 0:32:50.360
<v Speaker 1>specialized one to the degree that it can no longer

0:32:50.400 --> 0:32:54.280
<v Speaker 1>help me in climbing. Trees, So do a search for

0:32:54.520 --> 0:32:58.240
<v Speaker 1>II hands II fingers to get a sense of what

0:32:58.280 --> 0:33:01.360
<v Speaker 1>I'm talking about here. And that's exactly what I was

0:33:01.400 --> 0:33:05.600
<v Speaker 1>doing when I found a mention of a study that

0:33:05.640 --> 0:33:08.800
<v Speaker 1>I had not run across before. I thought I knew,

0:33:08.880 --> 0:33:12.080
<v Speaker 1>like all the main cool things about the ei. But

0:33:12.280 --> 0:33:15.920
<v Speaker 1>as it turns out that elongated middle finger is proportioned

0:33:16.560 --> 0:33:18.160
<v Speaker 1>as such. First of all, that it would be like

0:33:18.440 --> 0:33:21.720
<v Speaker 1>us having a foot long middle finger. But not only

0:33:21.760 --> 0:33:24.480
<v Speaker 1>do they use this to fish out wood boring insects

0:33:24.480 --> 0:33:30.000
<v Speaker 1>and grubs, but according to Anne Claire Fabre and this

0:33:30.080 --> 0:33:32.800
<v Speaker 1>is an evolutionary biologist at the Natural History Museum of

0:33:32.840 --> 0:33:35.640
<v Speaker 1>burn as cited in a Cassidy Ward article for Sci

0:33:35.680 --> 0:33:38.959
<v Speaker 1>Fi in twenty twenty two, they also use this finger

0:33:39.280 --> 0:33:42.880
<v Speaker 1>to pick their own noses, and they get the whole

0:33:42.920 --> 0:33:44.880
<v Speaker 1>finger in there to the point that they're able to

0:33:44.920 --> 0:33:47.640
<v Speaker 1>reach all the way back through their sinuses to the

0:33:47.680 --> 0:33:51.440
<v Speaker 1>back of their throats and then back out again. The

0:33:51.480 --> 0:33:55.440
<v Speaker 1>most prodigious nose picking in nature. It has to be right,

0:33:56.040 --> 0:33:59.880
<v Speaker 1>certainly with fingers with digits. You know, there may be

0:34:00.160 --> 0:34:04.280
<v Speaker 1>other strong candidates. They're involving animals with very like prehinsile

0:34:04.360 --> 0:34:05.440
<v Speaker 1>tongues and so forth.

0:34:05.840 --> 0:34:08.960
<v Speaker 2>But they zoologists right in with better nose picking in

0:34:09.000 --> 0:34:09.760
<v Speaker 2>the animal world.

0:34:10.080 --> 0:34:11.319
<v Speaker 1>I mean, this has got to be one of the

0:34:11.320 --> 0:34:13.879
<v Speaker 1>top cases. So I mean, that's okay. So I'm getting

0:34:13.920 --> 0:34:17.680
<v Speaker 1>off off topic a little bit from the evens and

0:34:17.719 --> 0:34:20.160
<v Speaker 1>the odds here, but that study or and or that

0:34:20.200 --> 0:34:22.640
<v Speaker 1>sci fi article is definitely worth picking up, in part

0:34:22.680 --> 0:34:26.520
<v Speaker 1>because they include an illustration of just how far the

0:34:26.560 --> 0:34:30.160
<v Speaker 1>finger is thought to go into the skull, and you

0:34:30.200 --> 0:34:34.800
<v Speaker 1>get like a cutaway of the II's skull to show you,

0:34:34.840 --> 0:34:36.239
<v Speaker 1>like how deep it goes, all the way to the

0:34:36.239 --> 0:34:38.040
<v Speaker 1>back of the throat. Pretty fascinating.

0:34:38.440 --> 0:34:40.479
<v Speaker 2>You really wouldn't want to, like trip and fall while

0:34:40.480 --> 0:34:41.040
<v Speaker 2>you're doing that.

0:34:41.600 --> 0:34:45.279
<v Speaker 1>No, all right, I have one more biological tie in

0:34:45.320 --> 0:34:48.279
<v Speaker 1>here concerning odds and evens and animals, and this has

0:34:48.360 --> 0:34:50.759
<v Speaker 1>nothing to do with the actual biology of the species.

0:34:50.800 --> 0:34:54.239
<v Speaker 1>It's all about the way we categorize them. We have

0:34:54.480 --> 0:34:59.680
<v Speaker 1>what are called tautonyms. This is when you have a

0:34:59.680 --> 0:35:04.319
<v Speaker 1>speed sees alike Rattus rattus, in which both parts of

0:35:04.360 --> 0:35:08.080
<v Speaker 1>the name are identical. The genus is rattus and the

0:35:08.120 --> 0:35:12.080
<v Speaker 1>species is also rattus, So you have Rattus ratus or

0:35:12.080 --> 0:35:12.880
<v Speaker 1>are rattus.

0:35:13.560 --> 0:35:16.399
<v Speaker 2>Yes, we've discussed a number of these before, But.

0:35:16.400 --> 0:35:21.680
<v Speaker 1>Then there's a step beyond mere tautonyms. There are triple tautonyms.

0:35:22.320 --> 0:35:26.439
<v Speaker 1>This is where the scientific names end up, I think,

0:35:26.480 --> 0:35:30.000
<v Speaker 1>being rather hilarious at times, and resembling as well magical

0:35:30.040 --> 0:35:35.440
<v Speaker 1>spells of summoning, bringing to mind incantations of beetle juice

0:35:35.440 --> 0:35:39.480
<v Speaker 1>and bloody Mary, where you're saying something three times in

0:35:39.480 --> 0:35:41.239
<v Speaker 1>a row, and anything said three times in a row

0:35:41.280 --> 0:35:46.240
<v Speaker 1>will start sounding silly. For instance, there is a buffo

0:35:46.239 --> 0:35:49.840
<v Speaker 1>bufo buffo, the European toad, so it's genus buffo, and

0:35:49.880 --> 0:35:52.839
<v Speaker 1>then the species is Buffo bufo beautiful. We also have

0:35:52.960 --> 0:35:55.880
<v Speaker 1>the black rat that's Rattus ratus ratus, and then we

0:35:55.960 --> 0:35:59.400
<v Speaker 1>have the South African giraffe or giraffa Giraffa.

0:35:59.000 --> 0:36:01.360
<v Speaker 2>Giraffe sounds the most like a spell.

0:36:01.880 --> 0:36:04.000
<v Speaker 1>And there are other fun examples as well, like the

0:36:04.080 --> 0:36:08.719
<v Speaker 1>European eagle owl Boobo Boobo boobo, the Eurasian magpie or

0:36:08.760 --> 0:36:12.640
<v Speaker 1>Pika Pika Pika, and these are all again richly amusing,

0:36:12.680 --> 0:36:15.200
<v Speaker 1>because anything you say three times it's just gonna sound silly.

0:36:15.400 --> 0:36:17.120
<v Speaker 2>Wait, isn't that what Pikachu says?

0:36:17.719 --> 0:36:20.200
<v Speaker 1>Pikachu's definitely, says Pikapka. I don't know if there's a

0:36:20.200 --> 0:36:21.879
<v Speaker 1>third Peka in there or not for.

0:36:21.880 --> 0:36:23.239
<v Speaker 2>When Pikachu really means it.

0:36:23.520 --> 0:36:28.759
<v Speaker 1>Yeah, another interesting thing about this is you'll only find

0:36:28.800 --> 0:36:32.879
<v Speaker 1>these in zoology because they are forbidden in botany under

0:36:32.880 --> 0:36:37.120
<v Speaker 1>the International Code of Botanical Nomenclature. So you're not going

0:36:37.200 --> 0:36:41.080
<v Speaker 1>to find anything like cannabis, cannabis, cannabis because it's just

0:36:41.200 --> 0:36:44.279
<v Speaker 1>forbidden that we don't do that in botany. Leave that

0:36:44.320 --> 0:36:46.680
<v Speaker 1>to the zoologists. They're the silly ones.

0:36:46.960 --> 0:36:49.000
<v Speaker 2>Well, I like this. I think the botanists should do it.

0:36:49.000 --> 0:36:50.560
<v Speaker 2>Maybe they just don't have the guts.

0:36:51.280 --> 0:36:53.279
<v Speaker 1>Yeah, I didn't get in deep enough to find out

0:36:53.320 --> 0:36:56.120
<v Speaker 1>like when this law was laid out and like how

0:36:57.000 --> 0:36:59.120
<v Speaker 1>for what reason? Like why did they really need to

0:36:59.120 --> 0:37:01.880
<v Speaker 1>take a stand on this. But maybe we'll have to

0:37:01.880 --> 0:37:02.959
<v Speaker 1>get into that another time.

0:37:03.480 --> 0:37:05.799
<v Speaker 2>I'm just kidding with you botanists. I know you have

0:37:05.800 --> 0:37:09.000
<v Speaker 2>plenty of courage. All right, Does that do it for

0:37:09.120 --> 0:37:10.880
<v Speaker 2>this series? On even an odd.

0:37:11.239 --> 0:37:13.360
<v Speaker 1>I believe so. Yeah, like you said, we've had our

0:37:13.440 --> 0:37:17.040
<v Speaker 1>third episode. We had a nice odd number of episodes

0:37:17.080 --> 0:37:18.920
<v Speaker 1>for it, so I think we're good to go.

0:37:19.320 --> 0:37:23.360
<v Speaker 2>Obviously, there are even an odd instances of pretty much everything.

0:37:23.440 --> 0:37:25.960
<v Speaker 2>So we could keep going forever, but we got to

0:37:26.000 --> 0:37:27.560
<v Speaker 2>stop somewhere exactly.

0:37:27.680 --> 0:37:31.439
<v Speaker 1>Yeah, yeah, So we'll go ahead and you call it here.

0:37:31.680 --> 0:37:33.759
<v Speaker 1>We want to remind everybody that's Stuff to Blow Your

0:37:46.719 --> 0:37:50.120
<v Speaker 1>a weird film on Weird House Cinema, and then we

0:37:50.160 --> 0:37:54.120
