Are we as rational beings... - Fairlane
I think it's more true to say that we are only partly rational beings.
Nobody has more contempt for woo woo than I do but I think Haidt raises an interesting question.
Step 1 - Superstitious beliefs arose as the side-effect of hypersensitive agency detection. We assume that random events are caused by unseen beings. Humans lived in small family groups of hunter-gatherers.
Step 2 - Religious ritual activates the "hive switch" and binds hundreds or thousands of people who are not genetically related into groups working for common goals.
Religions that are more effective in achieving group success dominate or absorb groups with less effective religious beliefs and rituals.
So what about now? As people increasingly reject irrational belief systems and become more individualistic do we lose anything valuable? If so what can replace it?
