First of all, being smart and educated, even doing some great thing in one's field, is no guarantee of being right all the time. Smart people can be wrong, just as dumb people can be right, no matter that on average, stupid people may be stupid, and smart people are generally smart.

And second, and more importantly, there is the good/evil aspect. Smart people can be very evil, very bad. Indeed I'm certain the most evil men in our history were no dummies by a long shot.

The greatest danger is believing that because someone is smart or an authority on something that means we should automatically accept what they say on things.
