Stereotypes are overgeneralized beliefs about characteristics of social groups. They assign traits to all members of a group regardless of individual variation. Stereotypes are part of social cognition and support prejudice. They are extensive and organized mental frameworks that are difficult to change, even with new information. Stereotypes are usually formed in childhood and influence thought and behavior. They provide fertile ground for prejudice and are useful for predicting behavior. Education is key to breaking stereotypes by providing continuous, appropriate information through social media and role models.
