Wisdom to give: Perspectival metacognition and the calibration of prosocial behavior across cultures

Humans engage in costly prosocial behavior with unrelated others at scales that short-term self-interest cannot explain. We propose that this capacity relies on perspectival metacognition (PMC)—a reflective reasoning style characterized by intellectual humility, open-mindedness, and self-transcendence beyond immediate concerns. In a preregistered cross-national study (N=13,500; nine countries), participants reflected on recent autobiographical conflicts and an incentivized carbon-offset donation experiment. Psychometric modelling of reflective tendencies revealed a latent PMC factor, which was robustly associated with larger incentivized donations and a general prosocial tendency across six real-world domains (e.g., voting, volunteering, pandemic norm adherence). These associations were consistent across experimental conditions and cultures, equivalent in magnitude to the combined effect of socioeconomic markers, and robust to adjustment for trust and personality traits. Exploratory analyses further suggested a “capacity and scope” account: the link between PMC and prosociality was strongest among individuals with higher resources (income, education) and a more expansive self-concept (inclusion of strangers in the self). These findings identify perspectival metacognition as psychological software that calibrates deliberation toward the collective good, particularly when ecological conditions and social orientation afford it.
