Episode 486: Why We’re So Bad At Predicting Romantic Compatibility

Most of us think we know what we’re looking for in a partner. We have a “type,” a mental checklist, and the belief that if someone checks enough boxes, everything else will fall into place. But decades of research suggest that attraction and compatibility don’t work that way. In this episode, we’ll unpack how attraction really unfolds and why chemistry is so hard to predict. My guest is Dr. Paul Eastwick , a Professor of Psychology at UC Davis, where he serves as the head of the Social-Personality Psychology program. He hosts the popular podcast Love Factually with his long-time colleague, Eli Finkel, where they analyze rom-coms and romantic dramas from the perspective of relationship science. Paul is also author of the new book Bonded by Evolution. Some of the specific topics we explore in this episode include: What’s the link between what we say we want and who we actually fall for? Do we really have a “type” when it comes to romantic partners? Why is it so hard to predict whether two people will feel a spark? How can we improve our chances of finding a compatible partner? How much does long-term satisfaction depend on initial compatibility? You can check out Paul’s website to learn more about his work. Got a sex question?
