Arrogant people who think they know it all may be onto something, according to a recent study.

Researchers at Baylor and the University of Mart Hardin-Bayor found that being full of oneself when it came to rating one's intellectual arrogance -- an exaggerated view of intellectual ability and knowledge -- generally predicted academic achievement, especially on individual course work.

"One possibility is that people who view themselves as intellectually arrogant know what they know and that translates to increases in academic performance," researcher Wade C. Rowatt, Baylor professor of psychology and neuroscience, said in a statement.

For the study, researchers collected and analyzed data from more than 200 undergraduate students.

They found that when rating themselves on a "humble-ometer," people generally did not see themselves as others see them. Accordingly, nearly everyone may agree that someone like, say, Donald Trump is egotistical -- except Donald Trump. With group projects, other team members gave better evaluations to those they viewed as humble. Lastly, they found that people can agree about whether another person is intellectually humble or intellectually arrogant, but it takes time.

"If people are forming opinions about extraversion and someone talks a lot, it's easy to draw consensus about that person," Benjamin R. Meagher, lead author of the study, said in a statement. "But it's more challenging for groups to recognize what behavior reveals another person's humility, as opposed to simply being shy or unsure."

The findings are detailed in the Journal of Research in Personality.
