Joseph Henrich Quotes

For many Westerners, "it's natural" seems to mean "it's good." This view is wrong and comes from shopping in supermarkets and living in landscaped environments. Plants evolved toxins to deter animals, fungi, and bacteria from eating them. The list of "natural" foods that need processing to detoxify them goes on and on. Early potatoes were toxic, and the Andean peoples ate clay to neutralize the toxin. Even beans can be toxic without processing. In California, many hunter-gatherer populations relied on acorns, which, similar to manioc, require a labor intensive, multiday leaching process. Many small-scale societies have similarly exploited hardy, tropical plants called cycads for food. But cycads contain a nerve toxin. If not properly processed, they can cause neurological symptoms, paralysis, and death. Numerous societies, including hunter-gatherers, have culturally evolved an immense range of detoxification techniques for cycads. By contrast with our species, other animals have far superior abilities to detoxify plants. Humans, however, lost these genetic adaptations and evolved a dependence on cultural know-how, just to eat.

The results reveal the power of prestige: when the gold-starred player had the opportunity to contribute money first, he or she tended to contribute to, and thus cooperate in, the joint effort, and then the following player - the low-prestige person - usually did as well. So, everyone won. However, when the low-prestige player got to contribute money first (or not), he or she tended not to contribute to the joint project (not cooperate), and then, neither did the high-prestige player. Even
