An evolutionary psychology view of forgiveness: individuals, groups, and culture

We review the logic of an evolutionary perspective on forgiveness, highlighting how insight into the likely function of forgiveness - solving adaptive problems related to acquiring and maintaining social relationships - has productively guided research and theory. A combination of experimental, longitudinal, cross-sectional, and cross-cultural evidence supports the claim that victims' perceptions of harmdoers' relationship value and exploitation risk causally influence whether or not victims forgive harmdoers. We also review the nascent literature on the topic of intergroup forgiveness and consider how the concepts associated with interpersonal forgiveness, such as apologies, relationship value, and exploitation risk, might help us understand forgiveness between groups, cultures, and societies. Finally, we explore the intersection of evolutionary and cultural perspectives on forgiveness, and consider how concepts from these two research traditions might be integrated to help us understand forgiveness even better.
