"Psychologists Marilynn Brewer and her colleague Kathleen Pierce predicted that “when individuals, or social systems, are threatened by psychological, economic, or political loss,” social identities will be defined based on more exclusive and less complex categories that simplify the world, driven by a desperate need to reduce uncertainty. The result is increased discrimination and resistance to change."

"Psychologists examined whether being attractive has an influence on judges sentencing. It turned out that the more unattractive the felon, the higher the sentence. Results of three studies showed a minimum increase of 119.25% and a maximum increase of 304.88% on the severity of the sentence. Unattractive defendants are found guilty slightly more often than attractive defendants."
