A lot of people actually are better than that at verifying information as accurate before incorporating it into their belief system.

I don't know, one example I can think of immediately is when people here immediately assumed Andrew Tate had cancer because of some news article that mentioned that his lawyer wanted to have the court free him for medical reasons. People here were immediately like "OMG HE HAS CANCER AHAHAHAHA!!!" without even critically thinking that it was a ploy by his lawyer to get him out of custody. If it's bad news about someone they don't like or good news about people they do like, most people (even hexbears) are quick to believe it. Hexbears aren't immune to that either.
