The implications of this are hard to exaggerate. Researchers tend to split pride into at least two broad categories. So-called authentic pride flows from real accomplishments, like raising a difficult child, starting a company or rebuilding an engine. Hubristic pride, as Dr. Tracy calls it, is closer to arrogance or narcissism, pride without substantial foundation. The act of putting on a good face may draw on elements of both. But no one can tell the difference from the outside.
