I May Not Agree With You, but I Trust You: Caring About Social Issues Signals Integrity

What characteristics of an individual signal trustworthiness to other people? I propose that individuals who care about contentious social issues signal to observers that they have integrity and thus can be trusted. Critically, this signal conveys trustworthiness whether or not the target and the observer hold the same view on the issue. Five studies (N = 3,817) demonstrated the predicted effect of caring on integrity-based trust (Studies 1, 2, 3a, 3b, and 4)—even in cases of strong disagreement—across a variety of issues (Study 1) and when behavioral outcomes with real stakes were used (Studies 3a and 3b). This effect largely results from a perception of low-caring targets as particularly untrustworthy (Study 2). Additionally, participants trusted targets with staunchly opposing views about an issue even though they simultaneously disliked them (Study 4). These findings have important implications for how people form impressions of others and speak to potential interventions to help mitigate the growing ideological divide
