"Narcissists may start out popular, but people see through them in the long run"
Here's a definitive article about Donald Trump's campaign which manages to not name him:

A new exploration of how we make friends and influence people rigorously measured the emergence of popularity in small groups - first-year college students organized into 15 study groups of about 20 in Poland. In the first week of their assignment to a group and then again three months later, 170 of the freshmen named the person or people they most liked in their group. Upon recruitment into the study, each participant completed standard inventories assessing their narcissistic personality traits and gauging their emotional intelligence.
The findings: When a group of strangers is thrown together, individuals who score high on narcissism enjoy an early surge of admiration, recognition and friendship among their peers. But over time, their self-assurance and showmanship cease to build or sustain the growth of friendships.
Meanwhile, individuals whose strong social skills quietly reveal themselves over time build steadily on their modest base of initial admirers. In a popularity contest, the emotionally intelligent ultimately win.
