No one could see the color blue until modern times. I’ve always suspected that our language affects how we see the world, and this is a great example.
Mother Jones has a really interesting article on how our beliefs block new information: Pre-existing beliefs, far more than new facts, skew our thoughts. Feelings arise before conscious thoughts and color them. Confirmation bias gives more weight to facts that match our existing beliefs. Beliefs are adjusted to match the audience.
