Shakespeare got it wrong, research suggests

When Shakespeare wrote, “Uneasy lies the head that wears a crown," he may have had it backwards, suggests new research by psychologists at Stanford University and Harvard University. They say there seems to be a link between less stress and more control.

Stanford psychologist James Gross and a Harvard team led by Jennifer Lerner, a professor of public policy and management at Harvard's Kennedy School of Government, studied high-ranking government and military officials and found that the higher the leadership position, the lower the stress.

"We live as social beings in a stratified society," says Mr. Gross. "It's our relative status in a group that disproportionately influences our happiness and well-being."

Specifically, a growing literature suggests that more power is associated with less stress. Studies of health in the British civil service showed that higher governmental rank was strongly correlated with lower mortality rates. Stanford biology professor Robert Sapolsky's measurements of the stress hormone cortisol in baboons showed lower levels of the hormone in high-ranking troop members.

The new Stanford-Harvard study looked at both cortisol measurements and self-reported anxiety levels within a rarely studied group: high-ranking government and military officials enrolled in a Harvard executive leadership program.

Although evaluating stress is itself complex – cortisol levels and reported anxiety are not necessarily correlated – the researchers found that high-ranking leaders were less stressed according to both measures. The strength of the relationship was directly related to rank: the higher the position, the lower the stress.

To tease out the specifics of these results, the researchers asked, as Mr. Gross puts it, "What exactly about a job makes it a leadership role?"

The critical element seems to be a sense of control. The connection between power and tranquility was dependent on the total number of subordinates a leader had and on the degree of authority or autonomy a job conferred.

It's possible, in other words, that the feeling of being in charge of one's own life more than makes up for the greater amount of responsibility that accompanies higher rungs on the social ladder.

The present study is correlational, meaning it is unable to say whether leadership leads to low stress levels, or whether people who are predisposed to feel little stress are more likely to be leaders. But Mr. Gross and Ms. Lerner view the study as an initial look at a topic that has relevance to anyone who lives in our inherently hierarchical modern society.

"By looking at real leaders, people who really have a lot of real-world responsibility, we can learn a lot about stress and health in general," says Mr. Gross.
