 Information counts as cultural not by virtue of its content but rather by where it comes from, how it travels, and what it does. Culture is transmitted via behavior, and produces durable, non-ephemeral effects on behavior. Although it is not explicitly mentioned in Ramsey’s explication, variation in behavior, between individuals but especially between groups, has been diagnostically important for those seeking to integrate culture and cultural explanations into cognitive science. Many have sought to document patterns of behavioral diversity, and more recently patterns of psychological diversity, and show that they cannot be accounted for by genetic or ecological differences, but rather are the result of cultural diversity.
