A central component of wisdom is intellectual humility—the capacity to recognize and address the limitations of one’s own thinking. As a character trait, intellectual humility has been proposed to contribute not only to personal growth but also to societal well-being and success. This chapter examines intellectual humility as a key component of wisdom oriented toward societal progress and change. First, we provide a short introduction to the psychological study of intellectual humility as a character trait. Second, we review hypotheses and evidence concerning its individual and societal benefits across three domains of psychological and social functioning: knowledge acquisition and decision-making, social relationships, and collaborative thinking and learning. We then discuss how benefits in these domains may foster forms of wisdom that support societal change. Finally, we outline three directions for future research that may provide insights into how intellectual humility can be cultivated as a character trait that benefits both individuals and society.
