Individual animals can be thought of as having working memory, a system of temporary stores, and processes for manipulating them. But what about whole cultures? Is there a historical, cultural, analogue? Thinking of how knowledge doesn’t really accumulate accurately. You get the same sorts of gisting effects culturally as you do in individuals (I reckon, when in pub-chat mode). For instance details are omitted from textbook descriptions of studies in psychology—think of the effect on how people view the empirical data!
