A culturally evolved tool can restructure an individual’s mental capacities

Evidence

However, here’s the thing: skilled abacus users can also beat calculator users even when they are disarmed, without their abaci. That is, they can make purely mental calculations faster than calculator users; this is because the abacus evolved from counting boards, which date back to before the Babylonians, through a long process of selective cultural evolution. Analyses of the abacus suggest that it is optimized to the constraints and affordances of our visual perception and memory, making it easier for us to store numbers in visual working memory. Once fully trained, people, including young children, can do superfast mental arithmetic. They accomplish this by visualizing the abacus and often actually manipulate their fingers nonconsciously as if they were rapidly sliding the abacus beads around. Language appears to play little or no role in the calculation, except that at the end, people have to report their answers in Arabic numerals or their verbal equivalents. — Joseph Henrich, The Secret of Our Success, 747

• XREF: Speaks directly to the reader’s coercion-vulnerability interest: if culturally inherited tools and practices reshape individual minds, then controlling which cultural ‘tools’ a population receives is a lever on their thinking. — connects to: Complex tools preceded and drove the evolution of causal-model reasoning. — Joseph Henrich, The Secret of Our Success: How Culture…, 1041; Cultural adaptation physically rewires the brain and perception — Roderick M.
