And now I’ve come across an entirely new reason to be skeptical about the theories we have about how the brain works — cultural effects. In his book, The Geography of Thought, Richard Nisbitt discusses research that shows that how we think — our cognitive processes — are influenced and shaped by culture. For example, if you show people from “the West” (US, Europe) a picture, they focus on a main or dominant foreground object, while people from Asia pay more attention to context and background. Asian people who grow up in the West show the Western pattern, not the Asian pattern, showing that this is based on culture, not genetics.
