In the study of social psychology, stereotype is understood as having an over-generalized notion about an individual based on his/her particular society or group.
In most cases, it is the practice of developing a negative attitude towards individuals or groups of people who come from a particular community.
For instance, when an individual develops a negative attitude towards another individual just because he/she is from a community that is usually perceived as bad or inferior, it is called stereotyping.
