Regarding people's reactions to public policymaking, an organizational justice framework has been introduced. Although these studies showed a link between fairness perceptions and attitudes toward public policy and authority, results concerning more behavioral consequences and the moderation of outcome favorability are less clear. The present research explored the voice effect on people's reactions to public policymaking, as well as outcome favorability as a boundary condition to it. Two different settings and use of different designs (a scenario and an experiment) yielded convergent results that people's reactions to public policymaking were more favorable when they had voice than they did not and outcome favorability moderated the voice effect. More precisely, the voice effect was stronger when the outcome was unfavorable than favorable.
