A few decades ago, social scientists believed that only "rigid, repressed, and authoritarian" people possess stereotypes (Paul 18). However, according to several recent studies, stereotypes are used unconsciously from Everyone in the World Annie Murphy Paul proposes that stereotypes form because people categorize others into certain groups in terms of gender, age, and race, and then evaluate them with in-group/out-group dynamics, which means that people look down on them. who are not part of their group to elevate themselves. Aside from obvious differences between humans, such as gender, Forster, Gerger, and Leder (2013) propose that even mundane factors such as facial expressions. influence stereotypes and contribute to people's evaluation of others. Categorization and unconscious evaluation have strongly influenced Chinese attitudes towards Northeastern Chinese. An overwhelming stereotype, widely held among Southern Chinese, describes the Northeastern Chinese as difficult to deal with, short-tempered and violent. The example supports experts' ideas that people unconsciously carry stereotypes, categorize and evaluate others in terms of groups, and judge people based on facial appearance. Furthermore, the example suggests that people also rank others considering regional differences and evaluate others taking into account their physique. Everyone carries stereotypes with them, even without even realizing it. In “Where Bias Begins: The Truth about Stereotypes,” Annie Murphy Paul argues that even if a person is not racist, sexist, or anti-Semitic, they still carry stereotypes, known as automatic or implicit stereotypes (Paul 17). Paul mentioned an experiment conducted… halfway through the article… on Northeastern Chinese, it is safe to draw the conclusion that stereotypes are deeply ingrained in everyone's bones, even though they may never realize they are. using them to judge others. People are born with the intellectual ability to classify and evaluate people into groups. In-group/out-group social dynamics lead them to devalue people who are outside their group, which causes stereotypes to form. Many factors influence stereotypes of people, such as race, age, gender, and facial appearance. From examining the "Northeastern Chinese" stereotype, it appears that region and physical appearance also have effects on stereotypes. Although it is almost impossible to erase stereotypes from us, since stereotypes are always associated with negative qualities, it is important that people refrain from judging people who have stereotypes..
