And that’s why beliefs can be dangerous. Belief requires an unwavering commitment to a thought or argument regardless of good arguments and evidence against it, meaning you are likely to reject the arguments and evidence if you already believe it to be true. It’s the same reason religious people stay in their religion or atheists stay atheists, the same reason Nazis stay Nazis or Leftists stay Leftists.
Belief does not require “unwavering commitment” in the face of contrary information. Many people treat their beliefs that way, and I treat a minority of my own beliefs that way as well. But believing that you objectively know what’s right about something doesn’t preclude openness to amending that belief, imo. Both are important, as a general rule we should neither presume ourselves to be wrong in our beliefs nor forbid ourselves from considering it a possibility.
