Pretentiousness is a behavior or attitude characterized by an exaggerated sense of importance or superiority. Individuals who are pretentious often try to impress others by showcasing their knowledge, taste, or social status, even if it is not genuine. This can manifest in various ways, such as using complex language, flaunting expensive possessions, or adopting exclusive interests. People may perceive pretentiousness negatively, as it can create barriers in social interactions. It often leads to feelings of alienation or resentment among peers. In contrast, authenticity and humility are generally valued traits that foster genuine connections and understanding among individuals.
