Another breed of character has come into being that is like authority characters, but more like us. He is an extremely smart criminologist who outsmarts serial killers, but he can't fix his own life. I think more as a person - he is smart, but not necessarily wise. Speaking of psychologists, the characters on the TV program Frazier are comical because in spite of their knowledge, they haven't risen above anything. Knowledge and experience are two different things.
Wisdom comes from experience.
So in creating characters that we can identify with, there are a lot of things to consider. We identify with people who are like us. The more they are like us, the more strongly we identify. If they are different from us, then we have to consider how that difference is going to affect how people identify with the character. Difference is intriguing.
