In this episode of Modern Wisdom, featuring Chris Williamson and Dr. Paul Eastwick, Did Evolutionary Psychology Get Dating All Wrong? - Dr Paul Eastwick explores relationship science challenges mating-market myths: compatibility, attachment, and modern dating Eastwick contrasts classic evolutionary-psychology framing (mate value hierarchies, large sex differences, short- vs long-term “strategies”) with a relationship-science view centered on attachment, dyadic processes, and compatibility that emerges over time.

Relationship science challenges mating-market myths: compatibility, attachment, and modern dating

Eastwick contrasts classic evolutionary-psychology framing (mate value hierarchies, large sex differences, short- vs long-term “strategies”) with a relationship-science view centered on attachment, dyadic processes, and compatibility that emerges over time.

He argues “mating market” competition mostly describes brief, stranger-based contexts (bars, swiping), where people initially agree on who’s attractive—yet that consensus fades as people get to know each other, making attraction more idiosyncratic.

Online dating amplifies early, checkbox-based screening and suppresses the conditions (shared groups, repeated exposure, vulnerability) that let compatibility and unique bonds develop.

He also emphasizes pro-relationship biases (idealization, derogating alternatives), the importance of being a “good lover” and supportive partner for relationship satisfaction, and why breakups are destabilizing due to attachment loss and the need for a coherent narrative.

Key Takeaways

The “mating market” is real—but mostly at the stranger stage.

Eastwick says market-like competition best describes initial attraction among strangers (parties, bars, swiping), where people show relatively high agreement about who is attractive. ...

Attraction becomes increasingly idiosyncratic with repeated exposure.

In his studies, “hot or not” consensus declines over time (from strong agreement among strangers to near-chance among friends/acquaintances). ...

Compatibility can rival or exceed consensus even early—especially face-to-face.

Eastwick argues that in speed-dating contexts, compatibility (“taste and timing”) is at least as influential as shared agreement about desirability. ...

Online dating worsens inequality by locking people into fast, box-checking filters.

Swiping environments magnify quick judgments and make traits like education or income act as hard gatekeepers, preventing people from discovering unexpected compatibility that might emerge through ongoing interaction.

Relationship quality is driven heavily by attachment-support dynamics and sexual experience.

Notable Quotes

[The mating market] describes initial attraction markets among strangers pretty well… but that tendency to agree actually fades over time.

Dr. Paul Eastwick

It is really, really lucky that people do this… she might be a six too, but she thinks I’m a ten.

Dr. Paul Eastwick

Ambition is a mild aphrodisiac… and there was no gender difference.

Dr. Paul Eastwick

Ask a deeper question than you think… That is the best experimental manipulation we have ever come up with… for getting people to like each other.

Dr. Paul Eastwick

Breakups are tough because… you’ve lost the person that you would normally go to… It’s like this double whammy of stress.

In speed dating, how do you quantify “compatibility” versus “consensus,” and what variables best capture compatibility beyond looks?

If online dating is structurally disadvantageous for idiosyncratic attraction, what concrete platform changes would make it more like repeated-exposure environments?

Online dating amplifies early, checkbox-based screening and suppresses the conditions (shared groups, repeated exposure, vulnerability) that let compatibility and unique bonds develop.

You claim attractiveness predicts near-zero long-term satisfaction—how do you reconcile that with common experiences like major weight change affecting desire? What would the ideal longitudinal study look like?

He also emphasizes pro-relationship biases (idealization, derogating alternatives), the importance of being a “good lover” and supportive partner for relationship satisfaction, and why breakups are destabilizing due to attachment loss and the need for a coherent narrative.

Chris Williamson

we were talking before we got started, uh, many of the past guests that have been on my show and much of my education, I think, into the world of mating dynamics, understanding relationship science, uh, has been informed by an evolutionary perspective.

Dr. Paul Eastwick

Yeah.

Chris Williamson

I think it's fair to say that your new book takes somewhat of an opposing perspective-

Dr. Paul Eastwick

Yeah

Chris Williamson

... to much of the evolutionary psychology position. Is that a, a fair assessment?

Dr. Paul Eastwick

I think that's fair. I am not using the standard like, this is not a standard nature-nurture thing. [chuckles] Uh, that's not where I'm coming from. I'm coming from a place of, actually, there's a different way of talking about human nature, a different way of talking about the way that humans evolve to form relationships, that I think is kind of missing out there, and that's more or less why I wrote the book.

Chris Williamson

What's your background? Because most people, when we talk about relationship science in the modern world, are going to be coming out of some kind of EP-

Dr. Paul Eastwick

Yeah

Chris Williamson

... mating research lab. What are you?

Dr. Paul Eastwick

Yeah. So I would say I'm a scholar of close relationships. There's a whole field, and we call ourselves relationship science. We're largely in the social and personality psychological tradition, but there are threads that connect to things like clinical psychology, family, uh, family studies, things like that. So we are informed by an evolutionary perspective, too. It's just a different one. So, for example, we talk about attachment perspectives a lot, and attachment has very deep evolutionary roots, going back to Bowlby and so forth, but it's just a little different from the standard evolutionary psychological perspective.

Chris Williamson

That's interesting. Okay, so [clears throat] what is your problem with the sort of classic Evo script-

Dr. Paul Eastwick

Yeah

Chris Williamson

... as you see it?

Dr. Paul Eastwick

Yeah. I think it overestimates a few things. It exaggerates some features of human mating, and it's only in a few cases where I'm like, "Oh, it's totally off the mark," but I think there's a big emphasis on things like mate value, the idea that some people are more desirable than others. There's an emphasis on gender differences, right? Like, men and women are really, really different in the mating realm. I also think there's this emphasis on, like, the short-term versus long-term mating distinction, and, like, some people are good at one or the other. Um, I think these ideas, uh, we've got a lot of misconceptions, to put it mildly, about [chuckles] those three things. Um, and I think once we kind of pick those things apart, we can, uh, put the pieces back together in a way that fits what I'd call the relationship science view, which is more about attachment, compatibility, and forming relationships through small networks.

Chris Williamson

Okay. Yeah, I, I think a lot of conversations that I would have would be about short term versus long term.

Dr. Paul Eastwick

Yeah.

Chris Williamson

A lot would be related to sex differences, preferences. I think the world of EP a lot of the time is talking about this, uh, sex differences, e-especially in terms of preferences for life, not just preferences in another parta- partner. Um, yeah, I, I, I think that's fair. I guess, right up top, the words mating market, probably one of the most ubiquitously used in all of the world of evolutionary psychology mating research.
