Stereotypes negatively affect the people that are being stereotyped. Experiencing the prejudice of a stereotype can cause aggression, lack of focus and a lack of self-control.
Stereotyping can affect the way that people treat each other. If one person stereotypes another in a negative manner, it can lead to that person being treated negatively. Using stereotypes to define a person is a form of prejudice. This type of prejudice often leads to incorrect or incomplete assumptions about other people based on the way they look, act, dress or conduct themselves in a social environment. Stereotyping can have lasting effects on people subject to the prejudice, causing negative changes in mood and behavior even after the incident is over.
