| Abstract: | This article reviews over sixty years of research on psychological barriers to intergroup conflict resolution and finds that scholars have identified eighty nominally different barriers that create or exacerbate intergroup conflict. In order to create a tractable list that would be more helpful to future scholars and practitioners, we consolidate this vast literature (e.g., by eliminating substantive and conceptual redundancies) to produce a list of twenty‐six “unique” psychological barriers. We further organize this inventory of barriers with a framework that distinguishes between “cognitive,” “affective,” and “motivated” psychological barriers. To better understand the literature ecosystem of research on psychological barriers, we employ a data visualization tool to illustrate the extent to which each of the twenty‐six unique barriers has been studied conjointly with every other barrier in the articles we reviewed. We then shift our attention to the work of scholars who have attempted, experimentally, to attenuate psychological barriers in negotiation and conflict settings, and identify five primary methods for doing so. Finally, we discuss the implications of our review for future work in this field. |
