"Ter poder tem efeitos comparáveis a uma lesão cerebral"

The Power Trip (Wall Street Journal):

Contrary to the Machiavellian cliché, nice people are more likely to rise to power. Then something strange happens: Authority atrophies the very talents that got them there. (...)

But first, the good news.

A few years ago, Dacher Keltner, a psychologist at the University of California, Berkeley, began interviewing freshmen at a large dorm on the Berkeley campus. He gave them free pizza and a survey, which asked them to provide their first impressions of every other student in the dorm. Mr. Keltner returned at the end of the school year with the same survey and more free pizza. According to the survey, the students at the top of the social hierarchy—they were the most "powerful" and respected—were also the most considerate and outgoing, and scored highest on measures of agreeableness and extroversion. In other words, the nice guys finished first.

This result isn't unique to Berkeley undergrads. Other studies have found similar results in the military, corporations and politics. "People give authority to people that they genuinely like," says Mr. Keltner.
Of course, these scientific findings contradict the cliché of power, which is that the only way to rise to the top is to engage in self-serving and morally dubious behavior. In "The Prince," a treatise on the art of politics, the 16th century Italian philosopher Niccolo Machiavelli insisted that compassion got in the way of eminence. If a leader has to choose between being feared or being loved, Machiavelli insisted that the leader should always go with fear. Love is overrated.

That may not be the best advice. Another study conducted by Mr. Keltner and Cameron Anderson, a professor at the Haas School of Business, measured "Machiavellian" tendencies, such as the willingness to spread malicious gossip, in a group of sorority sisters. It turned out that the Machiavellian sorority members were quickly identified by the group and isolated. Nobody liked them, and so they never became powerful.
There is something deeply uplifting about this research. It's reassuring to think that the surest way to accumulate power is to do unto others as you would have them do unto you. In recent years, this theme has even been extended to non-human primates, such as chimpanzees. Frans de Waal, a primatologist at Emory University, has observed that the size and strength of male chimps is an extremely poor predictor of which animals will dominate the troop. Instead, the ability to forge social connections and engage in "diplomacy" is often much more important.

Now for the bad news, which concerns what happens when all those nice guys actually get in power. While a little compassion might help us climb the social ladder, once we're at the top we end up morphing into a very different kind of beast.

"It's an incredibly consistent effect," Mr. Keltner says. "When you give people power, they basically start acting like fools. They flirt inappropriately, tease in a hostile fashion, and become totally impulsive." Mr. Keltner compares the feeling of power to brain damage, noting that people with lots of authority tend to behave like neurological patients with a damaged orbito-frontal lobe, a brain area that's crucial for empathy and decision-making. Even the most virtuous people can be undone by the corner office.

Why does power lead people to flirt with interns and solicit bribes and fudge financial documents? According to psychologists, one of the main problems with authority is that it makes us less sympathetic to the concerns and emotions of others. For instance, several studies have found that people in positions of authority are more likely to rely on stereotypes and generalizations when judging other people. They also spend much less time making eye contact, at least when a person without power is talking.

Consider a recent study led by Adam Galinsky, a psychologist at Northwestern University. Mr. Galinsky and colleagues began by asking subjects to either describe an experience in which they had lots of power or a time when they felt utterly powerless. Then the psychologists asked the subjects to draw the letter E on their foreheads. Those primed with feelings of power were much more likely to draw the letter backwards, at least when seen by another person. Mr. Galinsky argues that this effect is triggered by the myopia of power, which makes it much harder to imagine the world from the perspective of someone else. We draw the letter backwards because we don't care about the viewpoint of others.

No entanto, penso que há uma falha neste conjunto de estudos - os exemplos que levaram à conclusão de que "nice people are more likely to rise to power" foram feitos em ambientes (dormitórios de universidades, bandos de chimpanzés) em que o "poder" vem "de baixo" (isto é, alguém é influente nesses ambientes porque os outros membros do grupo lhe reconhecem influência); será que essas conclusões se manteriam num ambiente em que o poder vem "de cima" (p.ex., numa empresa em que os gestores intermédios são escolhidos pelos de topo)?
