So wait, according to this article: People who are nice, team players, selfless, etc. cluster near the top and the bottom of our hypothetical payscale graph. People who are narcissistic, egotistical, entitled, and overall "assholes" also cluster near the top and the bottom of payscale graph. But their data on narcissists only comes from CEOs? I would suggest that in aggregate this tells us basically nothing about how one should act to get ahead (Except maybe "Avoid the middle road of only being an asshole sometimes?"). It does however suggest that narcissism might be more common among CEOs than in the general populace, although again, not a predictor of being a particularly successful one. This is all of course setting aside the obvious problems of "How are they even defining these nebulous categories (In the case of narcissism, their measures were pretty unconvincing IMO. A lot of those decisions could have been made by marketing/PR people. There's sometimes value in the 'personal brand' of your CEO, even if they themselves are pretty humble in attitude) and even if we believe their definitions, how could they possibly be measuring them in a rigorous way in the wild"
