Why We Value Effort: The Evolutionary Logic of Partner Choice

At 7:46 · chapter starts 7:30

At the individual level, effort moralization makes perfect sense. Evolutionary psychologists describe 'partner choice' — the constant human evaluation of who will make the best ally, collaborator, or companion. Someone willing to wake up every morning for a grueling run they clearly despise is signaling something important: they won't slack off. Shariff illustrates this through his colleague Paul, a man of impeccable taste who runs every morning in what Shariff describes as an 'inelegant hobble' of apparent agony. Seeing Paul struggle, rather than stride, was what cemented Shariff's trust in him. Paul became not just a friend but a research collaborator. The heuristic is simple and potent: hard workers are good people. And it explains why you'd donate to a friend running a marathon for charity before you'd give to one watching a TV marathon for the same cause.
