Guala does not go far enough in his critique of the assumption that human decisions about sharing made in the context of experimental game conditions accurately reflect decision-making under real conditions. Sharing of hunted animals is constrained by cultural rules and is not "spontaneous cooperation" as assumed in models of weak and strong reciprocity. Missing in these models is the cultural basis of sharing that makes it a group property rather than an individual one.
瓜拉在批评这样一种假设时做得还不够充分，即人们在实验博弈条件下做出的关于分享的决定能够准确反映真实条件下的决策。狩猎动物的分享受到文化规则的限制，而不是像弱互惠和强互惠模型所假设的那样是“自发合作”。这些模型忽略了使分享成为群体财产而不是个人财产的文化基础。
