cognitive dissonance. For example, ask anybody if they have the ability to predict the future. They might look at you funny, and say, “Are you asking me if I have a crystal ball? No, I do not.” Okay then, do you select individual stocks. And do you regularly buy and sell them, in anticipation that their future price will be higher or lower? These people are paying lip service to the idea that they can't predict the future, because their actions contradict their words.
