Science of Attraction, Compatibility & Romance | Dr. Paul Eastwick
Dr. Paul Eastwick, a UC Davis psychology professor who studies how people choose partners. He explores how shared moments and time shape attraction, why dating apps distort choices, and how activities and social networks expand dating pools. He also covers money, ambition, texting, and which partner behaviors predict lasting relationships.

Marketplace vs. Compatibility
18:13 – 19:51
Dating apps amplify a few winners — extremely unequal attention.
But in everyday life, attraction evolves as people spend time together: strangers disagree ~1/3 of the time on who’s “hot.” That disagreement lets compatibility emerge, not just consensus mate-value.
The more people spend time together, it reduces some of those market forces.

How Attraction Forms: Stories > Traits
25:58 – 27:57
First impressions are usually middling, not instant sparks.
Attraction often builds via small shared moments — funny banter, emotional support, or a niche skill (e.g., aliquoting prowess) that becomes your private story. Those in-jokes and moments often predict whether a connection deepens.
I think what people are often trying to do is get enough moments...

Who Wants What? Men & Women — More Alike Than You Think
1:31:30 – 1:34:17
What people say ≠ what people do.
On surveys men stress attractiveness, women earnings. But in speed-dating and matchmaking (thousands of cases), men and women showed similar preferences for attractiveness and ambition when evaluating real people.
Trust your subjective experience in person — it often beats stated preferences.
Social Support & Gender Differences 462
50:02 – 54:36
Women often have wider social support networks; men get more of their emotional needs met through their partner.
Result: men tend to be more eager for commitment and may suffer more when a relationship ends. Cultivating friendships, activity groups, or couple-friends buffers stress and strengthens relationships.
Men just don't quite have their social lives put together in the same way.

Texting, Wit, and Selection Bias
1:13:58 – 1:16:09
Texting selects for quick, witty communicators — a modern selection bias.
Yet long-term relationship predictors are responsiveness, sexual/physical intimacy, and shared activities — things texting can’t fully reveal.
For anxious daters, texting reduces pressure, but real-world time together remains the highest-yield route to lasting bonds.
Their styles of communicating start to cohere.

Physical Intimacy = Relationship Glue
2:35:19 – 2:38:12
The subjective sense that your partner is a good lover is one of the strongest predictors of relationship satisfaction and whether you want to stay together.
Desire can ebb, but it can be rekindled through novelty, responsiveness, and shared experiences — it’s not inevitably lost.
Protecting physical intimacy is vital to long-term bond strength.
Feeling like this person is a good lover... is a very, very good sign.
