Two studies replicate and extend Lynn’s (2000) research on national personality and tipping customs. Study 1 finds that national extraversion and psychoticism, but not neuroticism, are related to customary tip sizes. Study 2 finds effects on attitudes and self-reported behavior of personality at the individual level of analysis that only partially support Lynn’s explanations for the national level effects. Discussion centers on alternative explanations for the national personality effects on tipping norms.
