Unpleasant affect fades faster than pleasant affect and this Fading Affect Bias (FAB) phenomenon is positively related to healthy outcomes and negatively related to unhealthy outcomes, which makes the FAB a healthy coping process/reaction. Rehearsal seems to be the cognitive mechanism responsible for the FAB. Although the FAB and its relation to healthy outcomes and rehearsal have been examined in many contexts, they have not been evaluated in the realm of politics. Therefore, we evaluated the FAB across event type and we examined the relation of FAB to political leaning (conservatism), unhealthy variables, healthy variables, and rehearsal for the 2016 US Presidential Election. We expected and found that FAB was larger for non-political events than for election/political events, and conservatism positively predicted FAB. We also expected and found that unhealthy/healthy outcome variables related to FAB in predictable ways. Importantly, we found that negative affect moderated the relation of FAB and conservatism, and rehearsal ratings mediated this 3-way interaction. The results supported emotion regulation models, such as the mobilization-minimization hypothesis and self-enhancement theory.
