INGROUP BIAS In Social psychology and sociology, an ingroup is a social selection to which one psychologically identifies as being part of or a member. On the other hand, an outgroup refers to a social group that one is termed as a misfit or not, and the individual does not identify. Groupings are resolute by factors fundamental to who we are, but in different cases, they are reached arbitrarily. The ingroup and outgroup divisions can be based on age, sex, race, or ethnicity, where if you do not belong to the named groups as the rest, you are an outgroup. The existence of diversity does not necessarily mean weakness, but at times there is beauty and strength associated with that.
