Episode notes

Modern dating can feel like a marketplace. We’re told we all have a “mate value,” that some people are 9s and 10s, and that the laws of evolution determine who gets chosen — and who gets rejected. But what if we’ve misunderstood what evolutionary science actually says about love?

Dr. Laurie sits down with social psychologist Dr. Paul Eastwick, author of Bonded by Evolution: The New Science of Love and Connection, to challenge some of the most pervasive myths about attraction and compatibility. Do dating app algorithms actually know who's right for you? Are we really all placed in different "leagues"? If you’ve ever wondered whether love is destiny, biology, or something you can actually create, Dr. Eastwick offers a surprising new perspective.
