Altruism in Humans

Abstract

This book takes a hard-science look at the possibility that we humans have the capacity to care for others for their sakes (altruism) rather than simply for our own (egoism). The look is based not on armchair speculation, dramatic cases, or after-the-fact interviews, but on an extensive series of theory-testing laboratory experiments conducted over the past 35 years. Part I details the theory of altruistic motivation that has been the focus of this experimental research. The theory centers on the empathy-altruism hypothesis, which claims that other-oriented feelings of sympathy and compassion for a person in need (empathic concern) produce motivation with the ultimate goal of having that need removed. Antecedents and consequences of empathy-induced altruistic motivation are specified, making the theory empirically testable. Part II offers a comprehensive summary of the research designed to test the empathy-altruism hypothesis, giving particular attention to recent challenges. Overall, the research provides remarkably strong and consistent support for this hypothesis, forcing a tentative conclusion that empathy-induced altruism is within the human repertoire. Part III considers the theoretical and practical implications of this conclusion, suggesting that empathy-induced altruism is a far more pervasive and powerful force in human affairs than has been recognized. Failure to appreciate its importance has handicapped attempts to understand why we humans act as we do and wherein…
