Superiority complex
A superiority complex is a defense mechanism that develops over time to help a person cope with feelings of inferiority. The term was coined by Alfred Adler (1870–1937) in the early 1900s, as part of his school of individual psychology.
Individuals with a superiority complex typically come across as arrogant, prideful, and disdainful toward others. They may treat others in an imperious, overbearing, and even aggressive manner.
