Going along versus getting it right: The role of self-integrity in political conformity

People often conform to the opinions of ingroup members, even when available evidence suggests that the group is misinformed. Following insights from the social identity approach and self-affirmation theory, it was hypothesized that people conform to salient opinions in an effort to maintain global self-integrity. In a series of experiments examining Americansʹ approval of President Obama and his policies, approval was consistently swayed by normative information (national polling data) but not by evidentiary information (indicators of national economic health), except under theory-predicted conditions. When participants had satisfied their sense of self-integrity with a self-affirmation exercise (Democrats in Study 1, Republicans in Study 2), or when they had low levels of American identification and thus were less concerned with national norms (Democrats and Republicans in Study 3), they showed the opposite pattern and were swayed by evidence in spite of contradicting normative information. The extent to which people are influenced by norms versus evidence in political judgment is shaped by social identity, one aspect of self-integrity. The results highlight a social psychological means to attenuate and potentially reverse conformity in the face of contradicting evidence, a finding with both practical and theoretical implications.
