Interpersonal sensitivity and self-knowledge: Those chronic for trustworthiness are more accurate at detecting it in others

► We explored if chronicity results in greater accuracy in interpersonal sensitivity. ► Chronicity for trustworthiness was determined with Me/Not Me judgments. ► Subjects judged if people cheated or cooperated in a real prisoner's dilemma game. ► Those chronic for trustworthiness could distinguish cheaters from cooperators. ► Signal detection analyses showed better discrimination, not response bias.
