Most of us just want to fit in, and believe what everybody believes.
Coming to your beliefs this way is not actually intelligent. We don’t do it consciously. It’s just tribalism or herding instinct or whatever.
So if everybody agrees with you then that’s a pretty good sign that you are wrong.
Most people agree that puppies and kittens are cute.
That’s just Big Cute propaganda. The puppy-kitten industrial complex has brainwashed us all. Have you even considered that tarantulas and anglerfish might be the true standard of cuteness?
Not even once.
