Social biases are a super fascinating thing to remind us that our brains don't actually always knew best. They actually take a lot of shortcuts in understanding the world, mostly to help us both survive, have "healthy" levels of self-esteem, and be able to use our brains for higher-level cognitive functions. I love them almost as much as I love the placebo effect and cognitive dissonance.
