It's easy to assume that someone who constantly says they're smarter than everyone else must be narcissistic. They may confidently correct other people, challenge opinions, or rarely admit they're wrong. However, psychology says that this conclusion isn't always accurate.

Confidence, biased self-evaluation, limited knowledge, or even past success can all influence how people judge their own intelligence.
