Cognitive Gadgets

While ‘nature vs nurture’ is an unhelpful dichotomy, most psychologists still assume that our species’ unique cognitive abilities, from language to mindreading, are innate products of genetic evolution. Here Celia Heyes provides a counter-argument to this assumption, arguing instead that human cognition is often the product of cultural evolution. Something like language is therefore not an ‘instinct’ but rather a ‘cognitive gadget,’ akin to a technological gadget, transmitted culturally rather than genetically. This is one of those books that makes you rethink your assumptions, and whether you agree or not with its claims, you come out smarter at the end.
