Relationship science challenges evolutionary theories and dating app algorithms
Science of Attraction, Compatibility & Romance | Dr. Paul Eastwick

- 2Real-world acquaintanceship and shared physical activities foster deeper emotional intimacy than digital messaging platforms.
- 3Active commitment protection and viewing past relationships as growth experiences are key drivers of partnership longevity.

Dr. Paul Eastwick debunks common dating myths regarding age preferences, showing that men and women share remarkably similar attraction patterns.
The brief
Relationship science is moving away from cold market-based formulas. Dr. Paul Eastwick from UC Davis joins the podcast to challenge traditional evolutionary theories of dating, showing why individual compatibility matters far more than consensus-based mate value.
While dating apps force users to judge partners on a standardized grid of superficial traits, real-life acquaintanceship allows highly specific, idiosyncratic quirks to spark deep, long-term attraction that algorithms simply cannot predict.
The data also challenges common assumptions about gender dynamics and commitment. Research shows that men are often more eager to commit early in relationships, and both genders actually share very similar attraction patterns when it comes to age preferences.
To combat the hyperverbal bias of modern texting and the isolation of screen-based dating, Eastwick advises the younger generation to actively rebel against algorithm-driven socialization by organizing small-group, real-world activities.
