Numerous empirical works document that discrete emotions have substantive and differential effects on politically motivated processes and outcomes. Scholars have increasingly adopted a discrete-emotions approach across various political contexts. There are different theoretical paths for studying discrete emotions. Appraisal theories contend that cognition precedes emotion, where distinct cognitive appraisal tendencies elicit discrete emotional reactions associated with specific coping mechanisms. Affective Intelligence Theory, another dominant paradigm in the study of discrete emotions in politics, argues for affective primacy. Others are more concerned with the level of analysis issue than the emotion-cognition sequence. For instance, Intergroup Emotions Theory calls for differentiating between individual-level and group-based discrete emotions, asserting that the latter form is a stronger predictor of collective political actions. Scholars also need to consider which methodological strategies they should employ to deal with a range of issues that the study of discrete emotions brings about. For instance, one issue is how to effectively induce a specific emotional state such as hope without also triggering other related yet discrete emotions such as enthusiasm in an experimental setting. Beyond these theoretical and methodological choices, there are various opportunities to diversify the field of study. Above all, the field needs more cross-national replications and extensions of U.S.-based findings to help resolve the debate over the universality versus contextuality of discrete emotions. The field would also benefit from the study of a wider array of emotional states by expanding beyond its main focus on negative discrete emotions. Contemporary developments—such as the increasing use of social media by the public and political actors—further offer novel platforms for investigating the role of discrete emotions.
