[RussianCow]

The one thing with this is that you have to be consciously careful of who you view as an authority on different subjects, or whose opinion on something is relevant. For a simple, everyday example, it's easy to follow a friend's recommendation to eat at a particular restaurant, even if that friend has completely different tastes in food than you do (which, in all likelihood, will result in a poor dining experience for you). Likewise, I think even smart, educated people often make the mistake of treating the word of powerful individuals as fact even if those individuals have absolutely no experience with or authority on the matter.
