When attitudes and habits don’t correspond: Self-control depletion increases persuasion but not behavior

This research tests a novel source of resistance to social influence—the automatic repetition of habit. In three experiments, participants with strong habits failed to align their behavior with others. Specifically, participants with strong habits to drink water in a dining hall or snack while working did not mimic others’ drinking or eating, whereas those with weak habits conformed. Similarly, participants with strong habits did not shift expectations that they would act in line with descriptive norms, whereas those with weak habits reported more normative behavioral expectations. This habit resistance was not due to a failure to perceive influence: Both strong and weak habit participants’ recalled others’ behavior accurately, and it was readily accessible. Furthermore, strong habit participants shifted their normative beliefs but not behavior in line with descriptive norms. Thus, habits create behavioral resistance despite people’s recognition and acceptance of social influence.

Theorizing from humanistic and motivational literature suggests attitude change may occur because high-quality listening facilitates the insight needed to explore and integrate potentially threatening information relevant to the self. By extension, self-insight may enable attitude change as a result of conversations about prejudice. We tested whether high-quality listening would predict attitudes related to speakers' prejudices and whether self-insight would mediate this effect. Study 1 (preregistered) examined scripted conversations characterized by high, regular, and poor listening quality. In Study 2, we manipulated high versus regular listening quality in the laboratory as speakers talked about their prejudiced attitudes. Finally, Study 3 (preregistered) used a more robust measure of prejudiced attitudes to testing whether perceived social acceptance could be an alternative explanation to Study 2 findings. Across these studies, the exploratory (pilot study and Study 2) and confirmatory (Studies 1 & 3) findings were in line with expectations that high, versus regular and poor, quality listening facilitated lower prejudiced attitudes because it increased self-insight. A meta-analysis of the studies (N = 952) showed that the average effect sizes for high-quality listening (vs. comparison conditions) on self-insight, openness to change and prejudiced attitudes were, ds = 1.19, 0.46, 0.32 95%CIs [0.73, 1.51], [0.29, 0.63] [0.12, 0.53], respectively. These results suggest that when having conversations about prejudice, high-quality listening modestly shapes prejudice following conversations about it, and underscores the importance of self-insight and openness to change in this process.
