Abstract: summary This article maintains that power enhances consumers’ ability to resist social influence but produces different resistance outcomes, depending on the level of certainty with which consumers hold their own attitudes. When attitude certainty is high, empowered consumers resist social influence by discounting others’ opinions. When attitude certainty is low, empowered consumers intentionally diverge from others’ opinions to signal their independence. Data from the first two experiments provide consistent support for the dual impact of power.
