We argue that some organisms are altruistically motivated and such altruistic motivation is adaptive. We lay out the helper’s decision problem—determining whether to help another organism. We point out that there are more ways of solving this problem than most people recognize. Specifically, we distinguish two kinds of altruistic motivations, depending on whether a desire to help is produced for one’s own sake or for others’ sake. We identify circumstances in which either kind of psychological altruism provides the most adaptive solution to the helper’s decision problem. As a result, we show that both kinds of psychological altruism are likely to be instantiated and selected for.
