Narcissism tracked from young adulthood to middle age

The belief that one is smarter, better looking, more successful and more deserving than others -- a personality trait known as narcissism -- tends to wane as a person matures, a new study confirms. But not for everyone, and not to the same extent.

The study, reported in the Journal of Personality and Social Psychology, finds that the magnitude of the decline in narcissism between young adulthood and middle age is related to the specific career and personal relationship choices a person makes.

The research tracked participants across two time points. The first occurred when they were 18 and just starting out as freshmen at the University of California, Berkeley. The second was 23 years later, when participants were 41 years old. Of the original 486 participants, 237 completed a new round of evaluations.

Participants at both time points answered questions from a survey designed to assess their narcissistic traits. For the follow-up study, researchers also asked about relationship and employment history, job satisfaction, and health and well-being.

"We looked at the different facets of narcissism in adults at age 18 and again at 41," said Eunike Wetzel, a professor of psychology at Otto-von-Guericke University in Magdeburg, Germany, who led the research with University of Illinois psychology professor Brent Roberts; Emily Grijalva, an organizational behavior professor at Washington University in St. Louis; and Richard Robins, a psychology professor at the University of California, Davis. "We focused on participants' vanity, the belief in their own leadership qualities and their tendency to feel entitled."

Each facet of narcissism was associated with several negative -- and in a few cases, positive -- outcomes for the individual, the researchers found. Those who had higher levels of vanity at age 18 were prone to unstable relationships and marriages, and were more likely to be divorced by middle age. But they also reported better health at age 41. In contrast, those who felt the most entitled as young adults reported more negative life events and tended to have lower well-being and life satisfaction at middle age.

"We originally hypothesized that the leadership facet of narcissism would increase," Roberts said. "In fairness to my co-authors, that hypothesis was mine, and it turns out I was wrong."

Leadership is associated with goal persistence, extraversion, self-esteem and a desire to lead. It is considered one of the least pathological elements of narcissism, Roberts said.

"We know from past research that another component of personality, assertiveness, tends to increase during this time of life," he said. "So, I thought it was reasonable to hypothesize a similar increase in the leadership facet. This either means the past research is wrong, or our read of the leadership component of narcissism is wrong -- it may actually be more negative than we thought. We have to figure this out in future research."

Vanity appeared to be most strongly linked to life events, the researchers found. For example, vanity declined more in those who entered into serious romantic relationships and those with children. But vanity declined significantly less in middle-aged adults who had experienced more negative life events than their peers.

"We also found that narcissistic young adults were more likely to end up in supervisory jobs 23 years later, suggesting that selfish, arrogant individuals are rewarded with more powerful organizational roles," Grijalva said. "Further, individuals who supervised others decreased less in narcissism from young adulthood to middle age -- meaning that supervisory roles helped maintain prior levels of narcissism."

Despite the differences between individuals, most of the participants who responded to researchers' questions again at age 41 saw a decline in narcissism as they matured, the researchers found.

"Very few people, only 3% of participants, actually increased in overall narcissism between the ages of 18 and 41," Wetzel said. "And some remained just as narcissistic at age 41 as they had been when they were 18 years old."

"The findings should bring comfort to those who are concerned that young people are problematically narcissistic," Roberts said. "With time, it seems most people turn away from their earlier narcissistic tendencies."
