00:00:41.900Yeah, this should be a very interesting conversation.
00:00:44.780I have a bunch of questions, mostly about men and women.
00:00:47.740But before we get started, can you give a brief background about who you are and what it is you do?
00:00:52.300I'm an evolutionary psychology professor, so I study human nature and I work at University of New Mexico. I did a BA at Columbia, my PhD at Stanford. I worked in England for 10 years and lots of other places. And I've mostly studied human sexuality and mate choice and how we fall in love and what traits we fall in love with.
00:01:14.860and then more recently i've gotten a lot more engaged in kind of political twitter
00:01:19.820and a movement called effective altruism and i'm currently working on
00:01:24.300um how to make artificial intelligence behave better with with humans wow okay that's cool
00:01:32.620well that's okay i'm going to add a couple questions in there then ai and then you said
00:01:37.180effective altruism yeah yeah the ea movement we can talk about that too if you want yeah no i
00:01:44.540definitely do. Effective altruism. Okay, cool. Wow. Well, I just have a whole bunch of questions
00:01:51.840to throw at you about sexuality, I think, and the dynamics between men and women. So first off,
00:01:59.140this is something I've been wondering for a while. Do females compete with each other? Because we
00:02:03.880know men compete with each other to get women. Do females compete with each other? Oh yeah,0.69
00:02:07.860very much so. I mean, the methods of what we call female versus female competition,0.97
00:02:12.420a very technical term. One thing I love about evolutionary biology is actually the technical
00:02:18.640terms are pretty intuitive and pretty easy to understand. Like my colleague Tanya Reynolds
00:02:24.680here at University of New Mexico specializes in studying female-female competition.
00:02:30.320Now, the typical forms that that takes tend to be more verbal and reputational rather than
00:02:37.080direct violent conflict. So women might derogate each other behind each other's backs. They might0.63
00:02:43.980try to manipulate each other's self-esteem if they feel like they're sexual rivals competing
00:02:49.800for the same guys or for the same social status. So it's not like women getting into0.65
00:02:57.260prehistoric MMA fights that much. It's more about using the weapons of verbal creativity
00:03:05.400and theory of mind and social sensitivity
00:03:08.480to just get subtle but sustained advantages
00:12:54.540So you said we've all evolved through virtue signaling
00:12:58.820and kind of smaller groups of people and tribes.
00:13:01.680um do you think that goes for kind of everybody back then across the board because i always assumed
00:13:07.440virtue signaling was well basically lying yeah i have more of a kind of neutral take like i i
00:13:14.960published this little book called virtue signaling in 2019 and i tried to emphasize like
00:13:22.480virtue signaling as a term became very common around 2016 with the trump versus clinton election
00:13:28.960And it was often used by conservatives to make fun of leftist people preaching at everybody, but not actually doing very much good.
00:13:40.420Right. So there's a negative kind of cheap talk version of virtue signaling where you're just running around on social media saying, you guys should do this.
00:13:50.800Don't do that. You're good. You're bad. Blah, blah, blah.
00:13:53.540my view is virtue signaling can be extremely positive for example if you got two single
00:14:03.960people and they're searching for mates and they meet up and they have a date they're trying to
00:14:09.660evaluate each other's kind of ethical compass and their personality traits like how agreeable how
00:14:16.860compassionate is this person and they'll talk about all kinds of things that basically boil
00:14:23.120down to virtue signals but some of those might actually be reliable indicators right so if they
00:14:29.600say look i i volunteer in a soup kitchen six hours a week it's hard to do that if you're a psychopath
00:14:36.960right somebody with no empathy couldn't stand to do that week after week so it is actually
00:14:44.640some kind of good signal of underlying values and personality traits
00:14:49.600I just wish that more people were selective about what they actually do
00:14:55.680and maybe do things that deliver real benefits to others
00:15:01.380rather than just working as really good signals of who you are.
00:15:32.620If humans evolved in small clans and tribes where you know everybody and you gather huge amounts of social information about people you interact with regularly, you might think there's just no room to be a psychopath.
00:15:47.100path. If you're regularly exploiting, deceiving, manipulating people, aren't people going to
00:15:52.800find out and push you out of the clan? And that's basically a death sentence, right? Exile equals
00:15:58.700death if you're in a prehistoric situation where you cannot survive by yourself out in the
00:16:04.660wilderness. Well, my personal hunch, actually, is that the rates of psychopathy in small hunter
00:16:13.740gatherer societies are quite low i think it's correct you can't survive as a psychopath in a
00:16:19.980small plan where everybody knows you however once you get civilization and agriculture and city
00:16:28.780states and big populations and you can move from group to group sequentially then suddenly there's
00:16:36.140a niche. There's a niche for the psychopath. So my hunch actually is psychopathy, sociopathy
00:16:45.720more generally, might be a fairly recent development and just kind of post civilization development.
00:16:53.460If you look at like the American West, like my ancestors were roaming around in the 1800s
00:16:59.840and you could you know if your reputation was shattered in one place you could move to a new
00:17:06.560town adopt a new identity build up a new reputation get people to trust you um and it it can work
00:17:16.320and um you know nowadays psychopathy seems to positively predict like number of babies
00:17:23.280especially for men ah yeah okay that makes sense because it's associated with um sexually
00:17:30.400exploitative tactics with seduction manipulation um not just like physical sexual coercion but also
00:17:41.840you know i've been a little bit peripherally involved in the pickup artist movement for
00:17:45.680like 15 years and i've talked to the puas and i know some of them and it's a weird movement because
00:17:53.280there are a significant number of like, actual hardcore psychopaths in it.
00:17:58.680We're trying to figure out, okay, how do I, you know, seduce, manipulate, deceive women?
00:18:05.720And then there's a bunch of normies and normal people with normal personalities in it, who
00:18:11.280legitimately just are confused by modern dating and want to learn good, honorable, you know,
00:36:41.860And so now, although it seems like males are much bigger and stronger than females, we're actually about as evenly matched in body size as any primate, as any mammal gets.
00:36:58.900That's an indicator that males and females were matching up, that they were forming long-term relationships that were at least socially monogamous, which means they hang out together, live together, sleep together, raise kids together, share a lot of food with each other, share care and compassion with each other, and so forth.
00:37:24.540So I think pair bonding is pretty central to human evolution, and it's what allowed
00:37:34.680things like the evolution of fatherhood, right?
00:37:37.840If you look at most mammal species, the dads don't do anything.
00:41:22.760Then, yeah, you don't care about the woman's intelligence because if it's just about, like, the guy getting a notch on his belt, what does it matter how smart she is?
00:41:32.300however there's good evidence that when men are getting more serious about choosing a long-term
00:41:37.820mate like who do i want to live with who do i want to marry men get much more selective
00:41:44.060about intelligence than they are for hookups right why because look you don't want0.81
00:41:52.140a low intelligence woman as a life partner sharing a house with who's incapable of understanding
00:41:59.740finances who who doesn't succeed in her career who's not a smart devoted mom to your kids0.51
00:42:09.660who's socially embarrassing if you're like trying to be a power couple in your local environment
00:42:15.900so uh and and we see this in the data on assorted mating like people of uh when people pair up they
00:42:25.500tend to match with someone with similar iq and that's typically a result of both the men and
00:42:31.260the women being pretty choosy about intelligence so for women out there who go yeah but i've gone
00:42:38.220on a bunch of first dates the men talk a lot they don't take any interest in me they don't seem to0.88
00:42:43.500care whether i'm smart or dumb they they don't probe like what do i know about the world yeah
00:42:49.740but that's a first date let the relationship develop what might often happen is after three
00:42:57.580months six months two years if you're wondering why why hasn't he proposed to me why hasn't he
00:43:06.540taken this to the next level well that's where the men are getting choosy right that's where
00:43:12.380the men are now evaluating not just physical attractiveness but the woman's intelligence
00:43:17.420and character and the way that men get choosy right is they fail to escalate the commitment
00:43:28.140right that's how they reject women oh so they'll just stay in it they'll just stay in it without
00:43:34.540moving in with you without proposing etc because look if you're if you're a guy and you've got a
00:43:42.060a girlfriend, and you're happy and you're having sex together, why would you suddenly
00:43:47.160just give that up for no reason? If you're happy in the relationship, but she's just
00:43:53.700not quite smart enough or stable enough or promising enough to marry, then you'll just
00:44:02.080kind of drift along indefinitely. And that's often, sadly, what male mate choice looks
00:44:09.760like huh and women don't do that right if they they'll they'll break it off faster i think and
00:44:17.280is that because of like child rearing and bearing age yeah because women's time is much more limited
00:44:23.920in terms of fertility so the men can kind of drift along and if if a guy's like uh yeah i had this
00:44:30.080girlfriend we got together i was 25 and we broke up when i was 32 no big deal i'm still going to
00:44:35.680be fertile for another 30 40 years but for the woman right he's he's burned through like seven
00:44:43.040years of her precious fertility window and so women women ain't got time for that they're going0.96
00:44:48.400to probably break it off earlier if they think he's not he's not the best hair bond mate
00:44:56.400and they should yeah absolutely probably yeah huge risk to them
00:45:01.200okay um what what body parts do you think are women attracted to like what um we don't have
00:45:10.800to just say body parts but like what traits are women attracted to the the classic male body type
00:45:19.040um we talk about shoulder to waist ratio a kind of b-shaped torso where there's broad shoulders
00:45:24.960there's a relatively narrow waist that indicates like you probably got some muscle and you're not
00:45:29.840too too plump and you're capable of doing stuff you're capable of um running and hunting and
00:45:36.480fighting and taking care of kids and doing all that stuff so the kind of like olympic swimmer
00:45:42.480physique um or the the mma fighter physique you know there's different varieties of this
00:45:50.640basically having muscle not having too much fat and being physically capable of doing a wide
00:45:55.600variety of things that's good and then in terms of psychological traits i've spent like 30 years
00:46:03.920studying this intelligence is important all those big five personality traits are important
00:46:11.920sense of humor which i've written quite a bit about which is both an indicator of intelligence
00:46:19.520right particularly verbal intelligence but also it's an indicator of social intelligence can you
00:46:24.560understand other people's minds enough to kind of tickle their brains with a funny story
00:46:31.920and also a good sense of humor is a good indicator of mental health because people who have depression
00:46:39.760or schizophrenia or severe autism tend not to be very funny in terms of like if they're trying to
00:46:46.800make a joke it typically doesn't work or they don't even bother making jokes so if someone is
00:46:52.400reliably um funny particularly in one-on-one interactions not just doing stand-up comedy
00:47:00.640then they're probably relatively mentally healthy in terms of like not having the major
00:47:07.920mental disorders that are that are big red flags
00:47:13.440and do you think humor plays do you think humor is more of a factor i guess in mate selection than0.56
00:47:19.440height i think they're both important i think you know women seem to have this this kind of
00:47:26.960heuristic or rule of thumb that i i want a guy who's at least as tall as me and preferably at
00:47:31.760least a couple inches taller than me so if you're a very short woman that's that's pretty easy right
00:47:38.240because there's about a three or four inch difference on average between the sexes so
00:47:42.720So if you're five foot tall as a woman, almost any man will do.
00:47:49.360I have some cousins, female cousins who are like 6'1", 6'2".
00:47:53.860If they're looking for men who are even taller than them,
