Stereotyping is the belief that all members of specific groups share similar traits and behaviors. Perceptual defense refers to the tendency to protect oneself from disturbing ideas or stimuli. The halo effect is the tendency to rate individuals on one trait alone, instead of multiple traits. Projection is a form of defense mechanism where an individual attributes their own thoughts, feelings, or motives onto another person or group.
