"The only thing worse than thinking everyone who disagrees with you is wrong is the opposite: being persuaded by the advice of those who need or want something you don’t." Also, the things you or they want don't have to be right. Take software choices. Their users all got their own reason why they prefer one over the other and all could be wrong. Which leads us to another rule. "Logic is an invention of man and may be ignored by the universe" If everyone of them can be doing things for the wrong reason; arguing if their choice does or does not support their reasoning doesn't help.
