Confidence can be attractive, but there's an important difference between healthy self-esteem and believing you're inherently better than everyone else. Psychologists describe a superiority complex as a pattern of attitudes and behaviors in which someone projects exaggerated confidence or superiority, sometimes as a way of masking deeper feelings of insecurity. The term was introduced by psychiatrist Alfred Adler, whose work on Individual Psychology suggested that exaggerated displays of superiority can develop as compensation for underlying feelings of inferiority.
Modern psychologists also caution that the phrase "superiority complex" is not a clinical diagnosis listed in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Instead, it is a useful psychological concept for describing certain communication patterns. No single phrase can prove someone has a superiority complex, and these examples are certainly not exclusive to men.
