A study by Zeigler-Hill and colleagues in China showed that while makeup and plastic surgery increased women's facial attractiveness, informing male evaluators that a woman had plastic surgery attenuated the positive effect on datability.
"Zeigler-Hill and colleagues in China, they actually tested... So it was makeup and plastic surgery that they tested on real women's faces, and they had men assess their attractiveness, their datability, etc. And what they found was that these methods worked to make them more attractive. But when men were informed—meaning once men knew like, 'Oh, this woman looks better, but she's had plastic surgery'—they had a reduced datability effect." (said at 0:08:30)
No published record matching the specific study by Zeigler-Hill and colleagues examining the effects of makeup versus plastic surgery disclosure on women's facial attractiveness and datability evaluations by men in China was located; this does not prove the claim false.
Scientific evidence demonstrates that women are more prone to experiencing 'the ick' than men.
"She's predicting that, 'cause women on average are choosier, women are more prone to the ick, which is I don't think anyone would disagree with that intuition, and we've now got good evidence that that's the case." (said at 0:13:21)

Research on dating apps shows that on Tinder roughly 4% of male profiles receive the vast majority of swipes, and on Hinge the top 10% of male users receive 60% of all likes.
"The swipe rates are very easy to measure. There's been a lot of research on this, and we mistakenly kind of overinterpret the findings of what people see on Tinder or on Hinge, which do show on Tinder something like 4% of the men get the vast majority of the swipes, and then larger numbers of women get liked versus men. Same thing on Hinge, that the top 10% of male users on Hinge get 60% of the likes." (said at 0:22:04)
No published record matching the claim that roughly 4% of male Tinder profiles receive the vast majority of swipes or that the top 10% of male Hinge users receive 60% of all likes was located; this does not prove the claim false. These statistics originate primarily from internal dating app company blog posts, informal datasets, and secondary online analyses rather than peer-reviewed scientific studies indexed in the biomedical literature.
Among hunter-gatherer societies, approximately 5% of first marriages last for life.
"in those kind of societies, though, often like a small number, small but like non-trivial number, 5% or so of first marriages do last for life." (said at 0:30:36)
No published record matching the claim that approximately 5% of first marriages last for life among hunter-gatherer societies was located; this does not prove the claim false. While ethnographic studies of foraging populations document high rates of early marital instability and serial monogamy, no empirical dataset or cross-cultural review quantifying that approximately 5% of first marriages endure for a lifetime was identified in the anthropological literature.

In a 45-condition virtual environment experiment manipulating income and local gender economic inequality, individuals who were poor or whose sex was disenfranchised upregulated mate preferences for resources across ranked, rated, and hypergamous measures.
"we did a 45-condition experiment that varied people's individual income and local gender economic inequality. And then we tried to see how those variables would predict changes in mate preferences... when people are poor, as in as individuals they're poor, or as in the opposite sex is rich and their sex is disenfranchised, they upregulate their mate preferences for resources. So they wanted—this is true in ranked preferences, in rated preferences, and also in hypergamous preferences" (said at 0:37:20)
No published record matching the specific 45-condition virtual environment experiment manipulating individual income and local gender economic inequality across ranked, rated, and hypergamous mate preferences was located; this does not prove the claim false.
In major US metropolitan areas, young women under 30 earn more on average than young men.

Institute for Family Studies data shows that women in the top 20% income quintile on average date down slightly economically.
"and this is from the Institute of Family Studies where they it's kind of it's a kind of a way of visualizing the data more than anything but they bucketed uh different income brackets. Yeah. And in the top 20% of women, like the top quintile, uh they are already on average are dating down very slightly economically." (said at 1:03:24)

Aggregate data from Keeper AI indicates that women are 12 times more likely than men to refuse marrying down on income, 6 times more likely on intelligence, and 4 times more likely on education.
"asked if they'd marry down on three axes. Women say no far more than men every time. Earns less. Women are 12 more likely 12 times more likely to refuse. Less intelligent, six times more. Less educated, four times more. Marrying down is a near dealbreaker for women and a non-issue for men." (said at 1:11:57)

David Buss's survey data shows that male and female mate preferences converged significantly across the 20th century, particularly following women's financial emancipation.
"throughout the 1900s, there's pretty good data from David Buss—it's hard to do it's hard to gather this survey data, but it does seem that over time throughout the 1900s um especially in the period after women's kind of financial emancipation, let's call it, uh mate preferences converged quite a bit between men and women."

A 2015 study by Norman Li found that when women possess their own financial resources, their mate preferences shift toward desiring partners who contribute more to domestic and child-rearing support.
"we see this even in um in Li's 2015 study, um where it does seem that when women have their own money, they recognize where it's like, 'Well, I have the financial thing kind of sorted. I really need like a helper at the nest a little bit more.'" (said at 1:25:00)
