Link: Dynamics of Political Ideologies

One of the major insights from works such as The Origin and Evolution of Cultures is that human societies can adapt and map themselves upon the environment with a few simple heuristics. A primary dynamic by which group behaviors propagate and enforce themselves is the do-what-my-neighbor-does rule-of-thumb. Obviously this is not always optimal. Sometimes it is needful to think for oneself. But thinking for oneself is cognitively expensive. Doing what everyone else does is cheap. Figuring out what you want to do for yourself is time consuming, and requires deliberation. There are analogies here between “hard & fast” reflexive cognition, and “slow & deliberate” reflective cognition.
