Many recent experiments in the field of behavioural economics appear to demonstrate a willingness of humans to behave altruistically, even when it is not in their interest to do so. This has led to the assertion that humans have evolved a special predisposition towards altruism. Recent studies have questioned this, and demonstrated that selfless cooperation does not hold up in controlled experiments. As I discuss here, this calls for more economic 'field experiments' and highlights the need for greater integration of the evolutionary and economic sciences.
许多近期行为经济学领域的实验似乎表明，人类愿意表现出利他行为，即使这样做不符合他们的自身利益。这导致了一种断言，即人类已经进化出一种特殊的利他倾向。最近的研究对此提出了质疑，并表明无私的合作在控制实验中站不住脚。正如我在这里讨论的那样，这需要更多的经济“实地实验”，并强调需要更大程度地整合进化和经济科学。
