So I am struggling with wrapping my head around the inability of people to instantly adjust to whatever is the best advice presented.

For instance, why do people keep religion when it is clear, that it's not the most likely "objective" truth.

Why do people not try to always optimize within reason? Why can people go through their lives without thinking about important concepts? They are deceived by false premises and randomness.

Why don't people just research and internalize beliefs that are based on logic?
