refers to the prejudice or discrimination based on physical appearance, where individuals are judged or treated favorably or unfavorably due to their looks. This bias can manifest in various contexts, such as employment, social interactions, and romantic relationships. It encompasses both positive biases, like the halo effect, where attractive individuals are perceived as more competent or trustworthy, and negative biases, such as stereotyping or bullying based on appearance. Lookism perpetuates unrealistic beauty standards and can have detrimental effects on self-esteem and mental well-being. Efforts to combat lookism involve promoting inclusivity, challenging stereotypes, and advocating for equal treatment regardless of physical appearance.
