Robert Merton's typology defines unprejudiced discriminators as individuals who do not hold personal prejudices but engage in discriminatory behavior due to social pressure or institutional norms. They may act 'unthinkingly' to conform to workplace practices, such as excluding women from certain roles, despite not harboring internal bias against them.

Immigrants often encounter both prejudice, which involves negative attitudes or beliefs held against them, and discrimination, which refers to the actual unfair treatment or exclusion based on those prejudices. These two factors frequently intersect to create significant barriers for newcomers in a host society.

Discrimination is a multifaceted social issue often fueled by cognitive biases such as stereotypes, irrational fears like homophobia, and the spread of misinformation. These elements work together to justify unequal treatment and systemic exclusion of specific groups within society.

Group closure is a sociological concept describing the process by which a group maintains its boundaries and preserves its privileges by restricting access to resources and social relationships. By limiting intermarriage and social integration, dominant groups can effectively exclude outsiders, thereby reinforcing social stratification and maintaining the distinctiveness of their own group identity within the broader social structure.

The 'culture of prejudice' theory suggests that prejudice is not merely an individual psychological trait but is learned and reinforced through cultural socialization. It posits that societal norms, media, and traditions can perpetuate biased attitudes, making them appear as natural or common-sense beliefs within a specific culture.

Discrimination refers to the actual actions or practices that result in the unequal treatment of individuals or groups. While prejudice is an internal attitude or belief, discrimination is the external manifestation of that bias, leading to tangible differences in how people are treated in social, economic, or political contexts.

The contact hypothesis suggests that interpersonal contact between members of different groups, under appropriate conditions (such as equal status and common goals), can reduce prejudice and improve intergroup relations. By working together on shared tasks, individuals are able to move past stereotypes and develop a more nuanced understanding of one another, thereby fostering greater social cohesion and cooperation within the workplace.

Prejudiced discriminators are individuals who hold negative attitudes toward a group and actively engage in discriminatory actions against them. Perpetrating hate crimes is an extreme form of this behavior, as it involves both the internal prejudice and the external, often violent, manifestation of that bias against others.

Charismatic authority, as defined by Max Weber, rests on the devotion of followers to the exceptional sanctity, heroism, or exemplary character of an individual leader. These leaders inspire intense loyalty and often emerge during times of social crisis. While the moral outcomes of their leadership vary drastically, Malcolm X, Joan of Arc, and Adolf Hitler are all frequently cited in sociology as individuals who exercised significant influence through their perceived charismatic qualities.

Max Weber identified charismatic authority as one of his three types of legitimate authority. It rests on the devotion of followers to the exceptional sanctity, heroism, or exemplary character of an individual leader. Unlike traditional authority, which is based on custom, or rational-legal authority, which is based on rules, charismatic authority is inherently tied to the leader's personal magnetism.
