Document Summary

We rely too heavily on intuition and common sense, this is demonstrated by 3 phenomena: hindsight bias: the tendency to believe, after learning an outcome that one would have foreseen it. Seems obvious after the outcome has occurred; also called i knew it all along phenomenon. Ex. tell 2 groups opposite results and both with defend why the result is true and say its common sense. Such errors in our recollections and explanations show why we need psychological research. Common sense described what has happened opposed to what will happen: overconfidence. Humans tend to think we know more than we actually do. We tend to be more confident than correct. People will be confident with their answer but will find out they were wrong: perceiving order in random events. In our natural eagerness to make sense of the world, we are prone to perceive patters. Random sequences often don"t always look random and are over-interpreted.
