Honesty is a near universally valued trait. However, the term honesty captures a litany of traits and behaviors, obscuring research on social perceptions and trait measurement of honesty and creating philosophical difficulties in accounting for what (if anything) unifies this diversity. We applied a prototype analysis approach to identify the most central elements of lay honesty conceptualizations, identifying elements that come to mind and are explicitly acknowledged as important to honesty. In five studies (N = 1,442), U.S. American participants generated 6,000+ free responses characterizing honesty and indicated which subtraits and behaviors best represent honesty. Truthfulness was most central to lay honesty conceptualizations across all studies and several centrality indices (frequency among responses and participants, agreement across participants, priority in lists, explicit ratings), though several other features were prominent. Findings illuminate social perceptions of honesty, critique popular measurement of trait honesty, and offer empirical foundations for philosophical analysis of honesty.
