Individual intelligence results from culturally accumulated tools rather than raw brainpower

Evidence

However, as you’ll see, we don’t have these tools, concepts, skills, and heuristics because our species is smart; we are smart because we have culturally evolved a vast repertoire of tools, concepts, skills, and heuristics. Culture makes us smart. — Joseph Henrich, The Secret of Our Success, 53
