The authoritarian personality is closely linked to prejudice and discrimination. Individuals with authoritarian traits often display rigid adherence to conventional norms and are intolerant of those who differ from these norms. This intolerance can manifest as prejudice towards out-groups, which are perceived as threats to the established social order. Authoritarian individuals tend to view the world in black-and-white terms and are prone to stereotyping and scapegoating. Their need for security and fear of social chaos drive them to endorse and engage in discriminatory practices against those who are different or whom they perceive as deviant. This prejudice is often directed towards ethnic, racial, religious, or sexual minorities. The authoritarian personality, therefore, not only influences attitudes towards authority but also significantly impacts social attitudes and behaviours towards various groups in society.

Gender and culture significantly influence the development of an authoritarian personality. Cultural norms and values play a pivotal role in shaping personality traits, including those associated with authoritarianism. In cultures where strict obedience to authority and adherence to traditional norms are highly valued, individuals may be more likely to develop authoritarian traits. Similarly, gender roles and expectations can impact the development of these traits. For instance, in societies where masculine roles are associated with dominance, power, and control, men may be more inclined towards authoritarian attitudes. Conversely, cultures that value egalitarianism and individual autonomy may be less conducive to the development of authoritarian traits. It's important to note that these influences are not deterministic but rather contribute to the likelihood of developing certain personality characteristics.

In clinical psychology, the concept of the authoritarian personality has been applied in understanding and treating various psychological issues. It is particularly relevant in the context of family dynamics, interpersonal relationships, and personality disorders. For instance, individuals with authoritarian traits may exhibit controlling and domineering behaviours in relationships, leading to conflicts and dysfunction. Clinicians may explore how these traits affect a client's interactions and relationships, helping them develop healthier ways of relating to others. Additionally, understanding authoritarian tendencies can be crucial in treating certain personality disorders, such as Narcissistic Personality Disorder, where there may be overlaps in traits such as dominance, rigidity, and a lack of empathy. Therapy may focus on addressing these traits and fostering more adaptive coping mechanisms. Furthermore, awareness of authoritarian tendencies can aid in understanding social anxiety or phobias related to authority figures, guiding targeted therapeutic interventions.

The possibility of changing or influencing an authoritarian personality through education or societal interventions is a topic of considerable interest. While personality traits are relatively stable over time, they are not immutable. Education that encourages critical thinking, empathy, openness to new experiences, and tolerance for diversity can potentially mitigate authoritarian tendencies. Societal interventions that promote inclusivity, social equality, and democratic values may also play a role in shaping less authoritarian attitudes. However, such changes are gradual and require consistent and long-term efforts. It is also crucial to create environments that challenge authoritarian norms and provide opportunities for individuals to engage with different perspectives. This approach can lead to a greater understanding and acceptance of social and cultural differences, potentially reducing the inclination towards authoritarianism.

The authoritarian personality theory, while developed in the context of mid-20th century totalitarian regimes, still holds relevance in understanding modern political attitudes and behaviours. Individuals with authoritarian tendencies may exhibit strong allegiance to traditional norms and authority figures, often showing hostility towards out-groups or those perceived as different. In contemporary politics, this can manifest in support for strict law and order policies, resistance to social and cultural changes, and endorsement of strong, often autocratic leadership styles. The inclination towards conformity and submission to perceived legitimate authority can influence political views, leading to polarisation and support for policies that reinforce traditional hierarchies. However, it is important to note that political attitudes are complex and influenced by a multitude of factors beyond personality traits alone. The authoritarian personality provides one lens through which to view political behaviour, but it does not account for all variances in political beliefs and actions.
