The old with us or against us conundrum. Like the world only has two outcomes for every decision.
There was a really cool social psych experiment done on this at some school a while back. It was almost like a choose your own adventure book but you had to choose one or the other outcome from a bunch of situations and they all snowballed into what your next choices were basically creating a set of beliefs from black or white answers. An overwhelming number of people did not like the people they became because of the linear answers.
If you find it online, hit me up. Sounds interesting.
