- act as if they're the sole expert on a topic (or every topic)?
- refuse to challenge their own beliefs and won't admit they're mistaken, even in the face of convincing evidence that would give reasonable people pause?
- don't engage others in open-minded, respectful dialogue?
- pressure others to admit they are right and try to prevent people from expressing their own, opposing views?
- are so emotionally attached to their beliefs they get defensive, even hostile, when someone challenges their views?
How often have you had to deal with people who have these characteristics?
