Guala is right to draw attention to the difficulty of extrapolating from the experimental evidence for weak or strong reciprocity to what is observed in the "wild." However, there may be more strong reciprocity in real-world communities than he allows for, as strikingly illustrated in the example of the Mafia.
瓜拉正确地指出了从弱互惠或强互惠的实验证据推断“自然状态”下的实际情况的困难。然而，真实世界的社群中可能存在比他所允许的更多的强互惠，黑手党的例子就鲜明地说明了这一点。
