Vad bestämmer om personer i en grupp samarbetar med varandra? En analys* av 36 experiment visar att intelligens har en gynnsam effekt:

Are more intelligent groups better at cooperating? A meta-study of repeated prisoner’s dilemma experiments run at numerous universities suggests that students cooperate 5% to 8% more often for every 100 point increase in the school’s average SAT score. This result survives a variety of robustness tests. Axelrod (1984) recommends that the way to create cooperation is to encourage players to be patient and perceptive; experimental evidence suggests that more intelligent groups implicitly follow this advice.

En plott ger en illustration:

För egen del fann jag detta resultat förvånande: jag trodde att smarta människor var mer egocentriska och socialt kyliga.

Se ett tidigare inlägg om hur smarta studenter i olika ämnen är. Nationalekonomer torde samarbeta väl!
