Are most stereotypes true?

         Most stereotypes have some naturally born for some reasons. You will probably guess who he is, why he should do, or what he is doing. All the use of stereotypes is predicted by this concept. However, you will find it is really hard to know everyone, it would spend a lot of time and energy to justify someone fairly.

    When coming out some stereotypes, we will naturally form some cognitive bias on some specific groups.  Most of us almost be wrong, because no one can fit in some ideas for sure. Perhaps they can be applied to the groups, but not to every individual.
