Abstract
Answering a question about performance of a behavior influences the probability of a person performing a target action in the future. Although this question–behavior effect has been shown across multiple contexts, several theoretical mechanisms have been suggested to drive the effect. While various explanations have been offered for the question–behavior effect, clear process evidence exists only for the theoretical perspectives of cognitive dissonance and attitude accessibility. In a series of experiments the current research tests the question–behavior effect from these two theoretical perspectives using a set of outcome measures not previously examined. Findings suggest that the act of self-prediction regarding socially normative behaviors generates cognitive dissonance, thereby obtaining greater compliance with subsequent requests to perform the behavior as a dissonance reduction strategy. Implications of the reported findings and directions for future research are provided.
