Dan P. McAdams is a professor of psychology and the director of the Foley Center for the Study of Lives at Northwestern University. He is the author of George W. Bush and the Redemptive Dream: A Psychological Portrait and The Art and Science of Personality Development. In the June 2016 issue of The Atlantic, he offers an interesting perspective on Donald Trump.
From the article’s conclusion:
Who, really, is Donald Trump? What’s behind the actor’s mask? I can discern little more than narcissistic motivations and a complementary personal narrative about winning at any cost. It is as if Trump has invested so much of himself in developing and refining his socially dominant role that he has nothing left over to create a meaningful story for his life, or for the nation. It is always Donald Trump playing Donald Trump, fighting to win, but never knowing why.
