0:12 Hello and welcome to Science Unscripted.

0:13 It's Connor here

0:14 and Gabe.

0:15 Take it away, Gabe.

0:16 Yeah, we got an email from Chuck

0:17 and this is the program director at WIT Zansville, Indianapolis.

0:23 This is a pocket of the Midwest that we weren't even aware

0:27 that that our our our show is is transmitted from these there

0:31 must be radio broadcasters all over this earth who are um

0:37 distributing our content and we thank you for that you know

0:40 and also just a big thank you saying that now uh reminds me

0:44 of or makes me realize I guess that we have spent a lot

0:47 of time thanking our fans all of our listeners out there

0:49 for for not just passively enjoying

0:52 the show hopefully but but writing in, commenting,

0:55 even visiting us in one case.

0:56 And we've kind of forgotten those folks.

0:59 Yeah.

0:59 And all the rebroadcasters, you mean the CBC's in Canada,

1:02 the NPRs in the United States,

1:04 the ABC's down under, all you guys out there who are broadcasting our stuff.

1:08 Thank you very much.

1:09 From Germany.

1:11 Yeah, pretty much.

1:11 Chuck writes, "Isn't the human equivalent of this bullying

1:16 by youths that often involves physical violence, too?" And what he's

1:20 You have to get into this, right?

1:21 what he's referring to um in the subject

1:24 of the email was the caning by the chimps.

1:26 And that was he's probably it's it's in response to my response to one

1:31 of the 17 chimps that we saw at the Arnham Zoo last week

1:36 and how he took a a a b she she took a bamboo cane

1:42 and for some reason started whipping one of the other chimps in the back.

1:49 I I never saw anything like that in all my time

1:52 at recess at Lincoln School and at the middle school in Beaver Dam.

1:55 Never ever with a weapon like that.

1:58 And and and out of nowhere because you had a recess teacher or recess teachers.

2:04 We did.

2:05 And they were the arbiters.

2:06 They were the referees.

2:07 They were the judges of who was guilty and needed a timeout and not

2:11 right.

2:11 Yeah.

2:11 That's something that human beings teach to one another at an early age,

2:15 hopefully that it is not fair to take

2:18 a cane and just start whipping your fellow.

2:20 No, but I'm I'm with Chuck here.

2:22 You take the referees out of it.

2:24 I I I'm not going to go full Lord of the Flies and say

2:26 it'll for anyone who understands that literary

2:28 reference that it'll go fully piggy.

2:31 Yeah.

2:31 Chaotic barbarism and and murder.

2:34 But if you don't have someone saying

2:37 you're getting a five-minute timeout, sit over there.

2:39 You're going to the principal's office.

2:41 you are now home for three days because

2:42 you picked up a potential weapon and hurt someone.

2:45 I wouldn't be surprised if it's the the most powerful Yeah.

2:49 or like the the early growers who

2:51 end up dominating hierarchically and whacking people.

2:54 I agree that that we have that instinct that is in our nature somewhere.

2:57 But it's also in our nature to to teach young kids not to do that.

3:03 to teach them that is completely unfair and absurd to use that kind of violence

3:09 to I don't know assert your dominance or show show that you're the leader.

3:13 We do it in other ways.

3:16 Yeah.

3:16 Yeah.

3:16 I mean this is I could go on forever on this.

3:20 Last thing I'll say on this is then part of the reason that may not happen

3:24 in a schoolyard without anyone stopping it is

3:29 that at some point if you whip enough people even if they're the smaller ones if

3:33 there are three or four or five and they

3:35 get together and say hey this this guy keeps hitting us with a with a cane

3:38 let's whip him.

3:39 Yeah.

3:39 So some sort of hierarch hierarchy or balance will end up

3:43 uh I guess asserting itself at least for a while equilibrium.

3:46 Another email, this one from Susan,

3:48 who wrote in to say that the whole first part of the email,

3:51 she's transfixed by our show consistently, very early in the morning.

3:57 So early that she probably shouldn't be awake, but she has insomnia,

3:59 but um our show kind of makes that insomnia feel better or or more worth it.

4:06 Wow.

4:05 One of the things she reacted negatively to as part

4:08 of that interview and maybe afterwards when we were sort of talking,

4:11 you you went on about how lovely that zoo is.

4:13 for her.

4:14 This is the dreaded Z word.

4:16 The Z-Word.

4:17 The Zword.

4:18 She can't even say it.

4:19 Doesn't want to say it.

4:20 Doesn't like the idea.

4:21 Doesn't like the concept of all of these animals

4:23 in something akin to a human prison as she views it.

4:27 And her question specifically was uh that she just

4:31 she wrote she had just heard the show about monkeys.

4:33 Of course, it was chimpanzees is what she means,

4:35 which I almost turned off because I cannot bear to hear of animals in prison,

4:38 the z-word, but I listened anyway.

4:41 How can you be so sure that the monkeys

4:45 are acting naturally when they're not in their natural environment?

4:49 Do human prisoners act quote unquote normal while constrained?

4:53 I would be more inclined to believe the premise about the monkeys sharing,

4:56 etc., when studied in their own natural habitat, not a custodial human confine.

5:03 So, I took this email, thank you, Susan,

5:05 and I forwarded it to the lead researcher, Kirsten, the one that we met up with.

5:10 Mhm.

5:10 And before I read her email, just a quick reminder, right?

5:13 This is about captive chimpanzees.

5:16 What are these situations where four of them

5:18 sharing a yogurt bowl can cooperatively share best?

5:22 And the conclusion that we discussed with her is is that when

5:25 a the hierarchically powerful individual is sort

5:29 of not that interested in the whole proceeding,

5:32 removed from it, apathetic even,

5:34 that it can work out best for the others to get a bunch of yogurt.

5:36 Anyway, she writes, "I agree that studying chimpanzees in the wild is important,

5:41 but for this study, a captive setting was more appropriate.

5:45 Regarding natural environments,

5:46 we made the decision to present the chips

5:47 with a situation they had never encountered before,

5:51 and one that wild chimpanzees will never encounter.

5:54 The aim was not to reproduce a common naturally occurring phenomenon,

5:58 but to use an easily repeatable paradigm that provides reasonably

6:02 high experimental control in order to investigate the research questions.

6:06 While there are other benefits to studying animals in the wild,

6:09 you lose the ability to account for the environment.

6:13 And she goes on to say basically in the second half of the email

6:18 that there's there's no there's no attempt here

6:20 to to generalize this beyond what they did.

6:23 There's no she's not saying that every chimpanzeee in the wild when

6:27 presented with a yogurt bowl in this situation would act this way.

6:29 this is what happens when chimpanzees and that um

6:32 I'm kind of paraphrasing here that this is just one piece of the puzzle as we

6:36 seek to understand our closest living relatives.

6:39 Well, yeah, and it's it's just it wouldn't be

6:41 possible if they weren't confined to conduct this experiment there.

6:45 Case case closed right there.

6:46 And again about that zoo to to refer to what Susan said,

6:51 it it's one of the nicest places I've been to in a long long time.

6:56 And I stand by I mean you don't know you can't go

6:59 into the into the into the soul or the mind of of an animal

7:03 and and and from based on looking at it over the fence whether it's

7:08 know whether it's feeling okay but I think these animals were doing all right

7:12 right and last thing I'll say on this subject we had

7:14 an interview months back where that I I posed that question myself

7:20 is it possible to say that by going to a zoo

7:25 and looking at animals that you otherwise have only seen in video form.

7:30 A tiger.

7:30 How many people have seen an actual tiger in the wild?

7:33 Not many.

7:33 How many people have seen a tiger in the zoo?

7:35 Does that raise my empathy for tigers worldwide and hence

7:40 it provides sort of a a a worldly global good

7:43 for those animals even if in theory one animal is taken

7:47 from the wild and and is no longer out in the wild?

7:50 And the answer is we don't know.

7:52 There's no evidence to say that that makes us all better people.

7:56 So I yeah I I just have to leave it there as an unknown.

7:59 What do you guys think?

8:00 Write to us at sudd.com.

8:02 We know you're you know that we love pretty much everything you guys have

8:06 to say and two two studies that got a lot of comments from you.

8:10 Let me there there have been follow-ups since

8:12 on the very same topic by other researchers.

8:16 And the first one is about um Fuyar's mood kite.

8:20 Remember when we talked about what was it?

8:22 What's the English translation of that?

8:24 Spring fatigue.

8:25 Spring fatigue.

8:26 The idea that in the German speakaking world,

8:28 there's this myth that's accepted by at least half the population

8:33 that for some reason people are just tired in the spring.

8:37 Work has been done at Purdue University um on whether the the the change

8:43 of the clocks co whether that coincides with changes in mood,

8:47 disruptions in mood and absolutely.

8:50 But the way they they looked at it was not the way it wasn't

8:52 a survey like the the case where

8:54 we spoke to the researcher from Switzerland Christine

8:56 Bluma about um she did a longitudinal study asked people all year long how

9:01 they're doing and then wanted to see if there was a change in the spring.

9:04 These people looked the researchers in Purdue looked

9:07 at social media posts around the the changes

9:10 of the clocks to and and scanned for words that would signal mood disruptions.

9:15 And it exploded in the spring and exploded in the fall.

9:20 When the ch when the clocks change,

9:22 people absolutely dis complain of depressive symptoms,

9:27 but more so in the fall than in the spring.

9:29 So there is an absolute change because one

9:31 of the things that we learned from Christine Bluma,

9:34 the Swiss study was that there was no change all year long.

9:37 Remember that when she said no changes in energy,

9:40 your energy level is relatively constant

9:42 even if your sleep patterns are altered.

9:45 Yes.

9:45 and you require, for example,

9:46 more sleep or or do sleep more in the in the fall or in the winter,

9:50 your energy when surveyed, when somebody asks you,

9:52 "How are you feeling today?" Energy

9:53 when somebody Yeah.

9:54 If the 800,000 or so posts that these researchers

9:58 analyzed are anything to go by, absolutely.

10:00 The change of the clocks results in a in a mood disruption,

10:04 but it's it's more it's worse in the fall.

10:07 It lasts for longer in the fall than in the spring.

10:11 And the

10:12 that's on the one hand surprising because uh spring forward you lose an hour

10:17 you lose the hour fall back you gain an hour hence you would

10:20 think that that's better than losing the hour on the other hand you

10:24 it's darker maybe in the fall you lose the hour of light

10:28 it depends here in Germany we do it at different times than for example

10:32 in North America so it really depends on where you are and how I there's

10:36 no one answer for everywhere in terms of how much darker or lighter it

10:38 is but that might have something to do with it but yeah that hits people.

10:44 Yeah.

10:42 That that change in in in time.

10:47 But it is interesting to for for two studies to be

10:49 done on a very similar topic and and wildly different results.

10:54 Um and the the the other study that we've we covered uh a couple of months back.

10:58 We went to a supermarket in Cologne, a simulated supermarket.

11:03 You have your city wrong, my man.

11:05 In Was it in Cologne?

11:07 No.

11:06 Was it in Bon?

11:09 Yes.

11:08 Oh my god.

11:08 I'm sorry.

11:09 I screwed that up.

11:10 It wasn't in Cologne.

11:10 was in Bon and we we learned from Dominic about where

11:15 food is placed but but they didn't have any results yet.

11:18 Remember there it's right at the infancy and he's

11:21 he's really excited about about uh this data to come

11:24 in at the University of London and the University of Southampton

11:28 they have absolutely done this experiment from 2018 to 2022.

11:33 So March 20, 2018 to April 2022, they looked at what happens when you put fruit

11:41 and vegetable right at the entrance of the supermarket.

11:45 And what happens

11:46 on the entrance, not the entrance, not not the exit when you're going out.

11:49 The first thing you you see is fruit and vegetable.

11:51 What happens?

11:52 Bananas.

11:52 Isn't that kind of how they Well, at least my supermarket does it, but go on.

11:56 Per They don't do it at these particular

11:58 or they weren't doing it and then they changed it.

12:00 put the fruit and veg right up front.

12:02 Per store per week, there were 2525

12:06 more purchases of fruit and vegetables on top

12:09 of the the purchase that are that are that would have been made anyways.

12:13 And I looked at the average of that particular size of supermarket

12:17 in that particular part of the world

12:19 between 7,000 and 13,500 purchases all week.

12:23 So this is a huge a significant increase in fruit

12:27 and veg purchases when you put it up front.

12:29 So Dominic, if you're listening or anyone else is listening,

12:32 because there were a lot of responses to that study,

12:34 people were very interested.

12:36 Yes, it matters where where food is.

12:38 And if if it's the first thing you see, then you will buy more of it.

12:44 It keep that in mind.

12:45 If the first thing you see is bubble gum,

12:46 you might be buying way more bubble gum than you need, kilograms of bubble gum.

12:50 Close your eyes until you see the fruit and vegetable

12:52 because it will it has a huge impact on on mortality.

12:55 my two the two supermarkets I tend to go to most

12:59 happen to do that and I say I'm saying happen

13:01 to but maybe there's some logic here in Germany there's

13:04 a reason they do that I don't know but the concrete

13:06 tip for all of you out there if you're able

13:08 to choose your supermarket just know that by going to the one

13:11 that have has them closer to the front maybe or maybe

13:14 more visual may you can see them you're going to

13:18 you're going to buy more fruit compared to the other

13:19 things you're going to buy there and fruit and vegetables happen

13:22 to just be better for you I'm just going to go

13:24 out and say that I know that that's not rigorous science, but

13:27 yeah, last thing very quickly here uh for any of you interested,

13:31 I I also talked about this in a Tik Tok video that will be on our channel

13:35 DW Science by the time you hear this, but I'll just say it here as well.

13:40 Um that there there was a recent statement

13:43 made by the US Health Secretary Robert F.

13:45 Kennedy Jr.

13:47 And like a lot of his his longer speeches, there was some because of the way he

13:53 presents information where the commas are more like periods.

13:56 These are these are separate thoughts that are

13:58 kind of back and backed onto each other.

14:01 He caused some confusion because he was talking about overweight

14:06 and obesity rates in the United States, which are 74%.

14:10 And then he goes on to talk about um how

14:15 a similar number of people are excluded from the military.

14:20 And he's talking here about kids.

14:22 Um about the same number,

14:24 74% of American kids cannot qualify for military service.

14:30 We're seeing a crisis in mental health that is linked in some way to our foods.

14:35 We're saying crazy.

14:37 Okay.

14:37 So, you got the 74% of kids who who are disqualified

14:41 from the military and there's a a mental health crisis that's linked to food.

14:48 Yeah.

14:48 But the 74% let let me just Yeah,

14:51 it it is it's confusing and and people were are confused about this.

14:55 the people who were exposed or or who listen to clips or or parts of the speech.

15:00 According to the Pentagon,

15:02 77% of young Americans or uh people who are qualified for service

15:08 in the military are not able to do so for a variety of reasons.

15:13 And the number one reason for being excluded

15:15 or disqualified from military service is connected to food.

15:20 It's because of obesity.

15:22 That's the most common or obesity or being overweight.

15:25 That's the most common reason to be disallowed

15:29 uh or or rejected from the military.

15:31 Number two, drug and alcohol abuse.

15:32 Now, he starts then kind of connecting it to mental health.

15:36 Mental health, which he says is somehow connected to food.

15:39 And that's the part that I want to make

15:40 clear here or dispute or or flat out reject.

15:44 that mental health or that the mental health crisis in the United

15:47 States that he talked about there is not a result of food or

15:51 yeah I guess the most conservative or cautious way to say it is

15:54 there isn't enough evidence out there to say that that is a primary

15:57 cause of a very real mental health crisis in young people I'm

16:02 talking about 12 to 17 year olds here specifically but there at least

16:06 according to the most recent research from about half a year ago there

16:09 are three primary factors for a dramatic rise in the number of people

16:13 who say that they are feeling hopeless or are sad or that have

16:18 been clinically defined as being depressed

16:20 or or describe themselves as being depressed.

16:23 And those three reasons are extreme digital exposure,

16:28 which is a fancy way of talking or or saying social media and smartphones.

16:34 Number two is social isolation or loneliness.

16:37 That's also a big part of why young people are suffering

16:41 mental health issues at a far higher rate than generations past.

16:44 The third is school andor academic pressure.

16:48 Those are the top three.

16:49 Nowhere in there do you see any connection at all to food.

16:54 Now some of our well- read or well listened fans out

16:58 there are aware of a really interesting area of research right now.

17:02 This is the connection between your gut microbiome and your you your

17:08 mental health

17:09 mental health yeah psychological health but I'm just going to for the sake

17:14 of time and clarity and to do that right when

17:16 we do it for now all I'm going to say is

17:18 that the evidence is not there right now to suggest that that's why

17:22 a lot of that research is still ongoing as well it's still being conducted

17:25 yeah and and completely fascinating the idea that it's

17:28 possible that your mental state is part of it

17:32 is is is directly affected by what you're eating

17:35 or not eating that is a very fascinating question.

17:37 Great question.

17:38 But what we know about young people suffering depression at rates

17:42 that are double what they were uh roughly 15 years ago.

17:49 Yeah.

17:48 That has other factors.

17:50 Again, I'll I'm just going to repeat them so

17:51 that you can repeat them if somebody brings this up.

17:53 This is extreme digital exposure, social isolation, loneliness,

17:58 and the pressure from school or your any sort of academic pressure.

18:02 All right, let me just really quick mention

18:05 the the the titles of the studies that I talked about.

18:07 The um the the the mood disruption and change of the clocks.

18:12 Social media analysis reflects the negative sentiments experienced at both

18:18 time changes with somewhat more depressive impact in early fall.

18:23 and the uh supermarket one impact of supermarket

18:28 fruit and vegetable placement on store sales, customer purchasing and diet.

18:33 Last one for me here is the the the data

18:36 I just referenced about young people in the US.

18:38 U you can find it yourself.

18:39 It's the youth mental health crisis

18:41 in the United States epidemiology contributors and potential solutions.

18:46 If you have any questions about anything we

18:49 have just talked about or didn't talk about,

18:52 that's a that's a more interesting one.

18:53 What didn't we talk about that you want to say something to us about?

18:58 That opens up, I think, infinite possibilities.

19:01 Please use them.

19:02 Sudd.com.

19:52 You've got someone in front of you talking to you.

19:55 You have the ability to judge.

19:58 Is that person smart or is that person not so smart?

20:04 Well, and are are you good at it?

20:05 Are you good?

20:06 Who is who is able to judge whether the person speaking to them is smart or not?

20:15 Science unscripted.

20:16 All right.

20:17 Hello everyone.

20:18 My name is Christophina.

20:20 I'm a personality researcher at the University of Vitta

20:24 and I'm doing a lot of individual differences research.

20:28 So what differentiates people from each other?

20:30 And we recently published an interesting paper on whether some people are

20:34 better at judging others intelligence and other people's are worse than that.

20:40 Let's let's hear it Kristoff.

20:43 Are some people better at judging

20:44 other people's intelligence than other people are?

20:48 Yeah, I guess so.

20:49 I mean the evidence is pretty clear on that.

20:52 So we found substantial we call individual differences.

20:55 Um so that that indeed the the the association it's

20:59 an association right there's the actual intelligence of the person

21:03 we're trying to uh estimate and our estimates and this association

21:08 is a lot stronger for some people than for others.

21:10 So yeah some people are better than others.

21:13 And how did you set up your experiment?

21:14 How how did you tell the difference between whether people could tell

21:18 if the person in front of them is dumb or or or smart?

21:22 Um yeah, I mean double smart is always hard

21:24 but yeah um what we what we did is uh firstand we we had a lot of video tapes

21:30 from from from people uh who also did an intelligence test.

21:34 So we we had videotaped them and know how

21:38 good they were at at uh at these intelligence

21:41 tasks and we we cut videos together to approximately

21:46 uh 1 minute uh from from 50 people.

21:49 One thing I have to ask here is the people who

21:51 were above average intelligence or or below or somewhere in the middle,

21:54 were they all saying the same thing in that video

21:59 or were they freestyling and saying whatever they wanted?

22:03 Yes.

22:04 So, so it was pretty standardized.

22:06 They had all the same task.

22:07 They were all asking answering the same questions.

22:11 So they were like reading a weather report

22:13 and they were asked to to explain what the uh

22:17 word symmetry means and and as all people

22:20 in the videos answer this question uh they were easily comparable.

22:24 I'd say I think what most of our listeners would want to know at this point

22:30 is what makes a person good

22:34 at judging intelligence or bad at judging intelligence?

22:37 Frankly, a lot of people who who are listening right now

22:39 might be worried that they're actually worse than they they thought.

22:43 We all like to think we're good at judging intelligence.

22:46 How how would we know?

22:47 Or the better way of phrasing that, what is

22:51 the most important factor according to your data about the viewers,

22:55 the people watching?

22:57 What changes whether they can do that well or not do it well?

23:03 Yeah.

23:03 I mean the most important factors I'd

23:06 say are hard to change because that's abilities.

23:09 So when you're intelligent by yourself

23:11 and you can't really easily change your intelligence

23:14 that makes you a good judge or when you are very good at perceiving

23:17 emotions in other people's faces uh you're

23:20 also better at judging intelligence but these are

23:22 abilities and you may train them but general intelligence is very hard to train.

23:29 So, so yeah, it's pretty much about dispositions, I'd say.

23:34 So, just to be clear here, Kristoff,

23:36 if I'm going to be good at judging whether other people are intelligent or not,

23:42 then I have to myself be intelligent.

23:47 That's the most important factor.

23:50 Yeah, I'd say that's one of the three most important factors.

23:54 Um, well-being might be an outcome.

23:56 So, so yeah, having having the the best abilities is,

24:02 I'd say, really good for you.

24:04 But in fact, it also only explained a small

24:08 amount of of variance in these uh Oh, that's pretty technical.

24:11 It only explained a small part of of judging other people.

24:15 And there's a lot of variance in in judging others that we could not explain.

24:20 So it's the one factor we know that that that is relevant but there may

24:24 be a lot of other relevant factors we haven't observed yet we can't measure yet.

24:30 How did you get interested in this topic of all

24:33 the the different avenues you could

24:35 have gone through in in psychological research?

24:37 Why did you end up focusing on whether

24:40 on on on how people judge the intelligence of of other people?

24:47 Yeah.

24:47 It's like I mean you you read a lot

24:50 of paper when when you have to to do your work

24:52 and and there's person perception is a very interesting

24:55 thing I think that's that's relevant throughout our whole life.

25:00 We we generally meet up with new people every day and uh

25:04 we're trying to to yeah see them correctly in in the best way

25:09 we can and and I think it helps us a lot when we

25:13 are able to to tell how people are gener how people generally are.

25:18 Kristoff, are Gabe and I intelligent based on what you've heard,

25:24 based on what you know or who?

25:27 Wait, who's more intelligent?

25:30 Oh, that's a very interesting question.

25:31 Wow.

25:32 Um, I can't tell.

25:34 I just had you on the on the earphones.

25:37 Uh, and I think the most important cues

25:39 are also visible in the behavior of the people.

25:42 Who is more intelligent of you?

25:44 Oh, I don't know.

25:45 I I try I I will dodge that question if I can.

25:51 That's a very intelligent answer.

25:52 Kristoff,

25:56 that was Kristoff Hina speaking to us from the the German city of Vitten.

26:02 And if you don't know, that's in the the rur pot of Germany.

26:07 And there's a really really good rap group from there called Vitten Untouchable.

26:12 Oh, really?

26:13 I just want you guys to know that.

26:14 I I love them.

26:15 Lman one, for instance, is one of the rappers in that group.

26:20 Okay.

26:19 Vitten Untouchable.

26:20 Check them out.

26:21 Okay.

26:22 Well, here's what I'm going to add

26:25 on the end here because after we talked to him,

26:29 he sent me an email cuz he was concerned that he there

26:31 was one point in particular that he had not expressed clearly enough.

26:34 He said, "I think I may have given the impression

26:36 that the ability to judge others is not changeable,

26:40 which was not my intention." that likely came

26:42 from focusing too much on the coralates we identified.

26:44 I do think it's changeable to some extent.

26:46 I just didn't communicate that.

26:47 And then the interesting part is he linked me to some very recent

26:51 research from the University of Müster here

26:54 in Germany in connection with other universities.

26:57 Long story short, there's an app where I clicked into it.

27:01 I'm not going to recommend it to any of you because it's in German.

27:03 Um, you watch videos of people or you videos are pictures of people

27:08 and then you have questions that you're supposed to judge them on.

27:11 And I'm just going to read three

27:12 of them here because I do think they're interesting.

27:14 One, there's a picture of a of a woman, a German looking woman.

27:17 She's smiling.

27:18 She has like a business jacket off and it says, "Does Claraara,

27:22 that's the name they've given her, does she sing

27:25 in the shower?" And based on this one photo,

27:27 it looks like a professional photo you'd see on LinkedIn.

27:30 Does she do it?

27:31 You've got another one um showing a guy and it says does does Kang or Kuang

27:36 I think his name name is does

27:38 he have basically his credit card number memorized?

27:41 Look at look at this picture of him.

27:42 Is he the type of guy who would have memorized his credit card number?

27:46 And the last one says Yan.

27:48 Yoken is this kind of wildl looking old guy longer hair.

27:51 You know like you're at a concert and suddenly this cool older person shows up.

27:56 That's him.

27:56 So Yan is there and it says, "Is this the kind of guy effectively

28:01 who swears while he's driving his car?" Now, it seems irrelevant,

28:05 but what's interesting about the research is you you make

28:07 these judgments and apparently over time you get better at them.

28:11 Now, judging things like these are these are sort of like is this stereotypes?

28:16 I mean, the the way that we go through our daily lives,

28:19 the better we get at stereotyping, it means we don't have to waste so much time

28:22 and energy on making these little judgments all the time.

28:24 We just have them we have them all set right

28:27 and what Chris is saying is based on these on findings connected to that it does

28:31 seem that people can improve their ability to judge

28:33 others and hence the ability to judge intelligence

28:37 why wouldn't that be a part of it so that's the message

28:39 for all of you if you think after talking or hearing

28:42 from Chris that you're like shucks I might not be good

28:45 at knowing whether other people are smart or not you can't train it

28:48 you'll get better with time and also

28:50 the question stands um are Connor and I smartt or or Yeah, smarter.

28:58 No, that Well, go for it.

29:00 If you want to go there, send us a message and we'll deal with it.

29:04 And I I really mean deal with the implications next week.
