From The Atlantic magazine way back in 2017, by Jerry Useem:
The first four paragraphs excerpted:
If power were a prescription drug, it would come with a long list of known side effects. It can intoxicate. It can corrupt. It can even make Henry Kissinger believe that he’s sexually magnetic. But can it cause brain damage?
When various lawmakers lit into John Stumpf at a 2016 congressional hearing, each seemed to find a fresh way to flay the now-former CEO of Wells Fargo for failing to stop some 5,000 employees from setting up phony accounts for customers. But it was Stumpf’s performance that stood out. Here was a man who had risen to the top of the world’s most valuable bank, yet he seemed utterly unable to read a room. Although he apologized, he didn’t appear chastened or remorseful. Nor did he seem defiant or smug or even insincere. He looked disoriented, like a jet-lagged space traveler just arrived from Planet Stumpf, where deference to him is a natural law and 5,000 a commendably small number. Even the most direct barbs—“You have got to be kidding me” (Sean Duffy of Wisconsin); “I can’t believe some of what I’m hearing here” (Gregory Meeks of New York)—failed to shake him awake.
What was going through Stumpf’s head? New research suggests that the better question may be: What wasn’t going through it?
The historian Henry Adams was being metaphorical, not medical, when he described power as “a sort of tumor that ends by killing the victim’s sympathies.” But that’s not far from where Dacher Keltner, a psychology professor at UC Berkeley, ended up after years of lab and field experiments. Subjects under the influence of power, he found in studies spanning two decades, acted as if they had suffered a traumatic brain injury—becoming more impulsive, less risk-aware, and, crucially, less adept at seeing things from other people’s point of view.
gotta chew on that one.
