When combining injunctive and descriptive norms strengthens the hypocrisy effect: A test in the field of discrimination.

The induced-hypocrisy is a paradigm in which people promote a normative behavior (normative salience step) and then recall their past transgressions (transgression salience step). It is an effective two-step procedure for encouraging prosocial behaviors. This study aims to explore whether discrimination can be reduced using the hypocrisy paradigm combining two kinds of social norms, namely injunctive and descriptive norms. We assigned 80 participants to descriptive norm-related hypocrisy, injunctive norm-related hypocrisy, combined-norm hypocrisy, and control conditions. Results showed that intention to adopt active normative behaviors was higher in the combined-norms than in the single norm hypocrisy conditions. We observed the same pattern in reducing discriminatory behaviors in the Cyberball game, which measures passive discrimination (exclusion). Our findings have both practical and theoretical implications. First, they provide a new and effective means for producing behavioral changes in the field of discrimination. Second, they contribute to further investigating the explanatory processes underlying the hypocrisy effect.

Three Decades of Research on Induced Hypocrisy: A Meta-Analysis.

Induced hypocrisy is a sequential, two-step, cognitive dissonance procedure that prompts individuals to adopt a proattitudinal behavior. The present meta-analysis of 29 published and nine unpublished induced-hypocrisy studies enabled us to test three key dissonance-related issues. First, is hypocrisy effective in promoting change in behavioral intention and behavior? Our analyses supported the idea that hypocrisy (vs. control) increased both behavioral intention and behavior. Second, does hypocrisy generate psychological discomfort? Results pertaining to this issue were inconclusive due to the small number of studies measuring psychological discomfort. Third, are both steps necessary to generate change? Effect sizes conform to the idea that the transgressions-only condition can increase both behavior and intention. Our meta-analysis raises a number of theoretical issues concerning the psychological processes underlying induced hypocrisy and highlights implications for practitioners.
