In Ricardo Blaug’s paper “Cognition in a Hierarchy,” he discusses a cognitive science explanation of hierarchy. Blaug argues that our cognition exists certain kinds of bias: confirmation of our existing knowledge, tendency to amplify our personal importance, and separation of socially structure to be external and independent of individuals. These factors combined allow elite groups to corrupt and subordinates to collude within a hierarchy.
I think it is interesting that how the underlying mechanics of a large social structure function and be broken down into small elements such as how individual’s cognition work. Blaug’s argument is qualified because each component of his argument is backed up by the result of relevant researches and experiments conducted by experts.
