Dr. Paul Eastwick, a psychology professor at UC Davis, has spent two decades studying how people actually form romantic relationships, and his findings often contradict the popular narratives.

The stated preference for older men and younger women did not hold up when people met face-to-face. This is just one of several findings that challenge the idea that dating is a simple market where people trade traits like attractiveness and income.

The Limits of the "Mate Value" Model

The common evolutionary narrative suggests that people have a stable "mate value" based on traits like physical attractiveness and status, and that they pair up accordingly. Eastwick acknowledges this model works in initial, anonymous settings—like a classroom demo where students with random numbers on their foreheads try to pair up, and those with low numbers get ignored. But the model breaks down when people spend time together. The key mechanism is that agreement about who is "hot" or "valuable" is surprisingly low. When people make simple binary judgments about a stranger's attractiveness, they agree only about two-thirds of the time. As people get to know each other, that agreement drops further. One person's "five" becomes another's "ten." Thi
