As a culmination of our intellectual humility grant in 2013, my co-authors (Mark Alfano, Kathryn Iurino, Paul Stey, Markus Christen, Feng Yu, and Danial Lapsley) have just published our new multi-dimensional measure of intellectual humility. Over five studies (N=3,651), two languages, and five years went into producing this paper in PLoS One, where we present our validate tool for measuring the trait of intellectual humility in people. Here’s the abstract:

This paper presents five studies on the development and validation of a scale of intellectual humility.This scale captures cognitive, affective, behavioral, and motivational components of the construct that have been identified by various philosophers in their conceptual analyses of intellectual humility. We find that intellectual humility has four core dimensions: Open-mindedness (versus Arrogance), Intellectual Modesty (versus Vanity), Corrigibility (versus Fragility), and Engagement (versus Boredom). These dimensions display adequate self-informant agreement, and adequate convergent, divergent, and discriminant validity. In particular, Open-mindedness adds predictive power beyond the Big Six for an objective behavioral measure of intellectual humility, and Intellectual Modesty is uniquely related to Narcissism. We find that a similar factor structure emerges in Germanophone participants, giving initial evidence for the model’s cross-cultural generalizability.
