Take a look at Adam Grant’s column, p. 6 of the New York Times Review section June 5, “’Be yourself’ is terrible advice.” This sounds akin to David Brooks.
Grant talks about “low self-monitors” (like me) who tend to “say what they mean and mean what they say” (like in the little film “Bulletproof Picasso”), but are more likely to be female. “High self-monitors: are the “always be closing” types. Actually, Donald Trump is a bit of both. But the extroverts, so to speak, are more likely to be tuned to what people “need”, even if the temptation is to oversell. Yup, people thought they needed subprime mortgages.
