Bill Bain

Mitt Romney’s old boss, recalled in Turnaround as the source of two pieces of management wisdom Romney carried forward. Bain argued there is a scientific basis for trusting your gut on people — that the subconscious brain reads body-language signals you aren’t consciously aware of, so first impressions can be as reasonable as any other input — which shaped Romney’s habit of “listening to what I feel in my heart about people.” Bain is also the source of the line Romney quotes on hiring for raw intelligence: “most things can be fixed, but smart — or dumb — is forever.”
