Guala appears to take social preferences for granted in his discussion of reciprocity experiments. While he does not overtly claim that social preferences are only by-products that arise in testing environments, he does assert that whatever they are – and how they evolved – they have little value in the real world. Experiments on animals suggest that social preferences may be unique to humans, supporting the idea that they might play a prominent role in our world.
