Biological impulses drive our emotions. We cannot do away with them—but we can do much to manage them. Self-regulation, which is like an ongoing inner conversation, is the component of emotional intelligence that frees us from being prisoners of our feelings. People engaged in such a conversation feel bad moods and emotional impulses just as everyone else does, but they find ways to control them and even to channel them in useful ways.

Imagine an executive who has just watched a team of his employees present a botched analysis to the company’s board of directors. In the gloom that follows, the executive might find himself tempted to pound on the table in anger or kick over a chair. He could leap up and scream at the group. Or he might maintain a grim silence, glaring at everyone before stalking off.

But if he had a gift for self-regulation, he would choose a different approach. He would pick his words carefully, acknowledging the team’s poor performance without rushing to any hasty judgment. He would then step back to consider the reasons for the failure. Are they personal—a lack of effort? Are there any mitigating factors? What was his role in the debacle? After considering these questions, he would call the team together, lay out the incident’s consequences, and offer his feelings about it. He would then present his analysis of the problem and a well-considered solution.

Why does self-regulation matter so much for leaders? First of all, people who are in control of their feelings and impulses—that is, people who are reasonable—are able to create an environment of trust and fairness. In such an environment, politics and infighting are sharply reduced and productivity is high. Talented people flock to the organization and aren’t tempted to leave. And self-regulation has a trickle-down effect. No one wants to be known as a hothead when the boss is known for her calm approach. Fewer bad moods at the top mean fewer throughout the organization.

Second, self-regulation is important for competitive reasons. Everyone knows that business today is rife with ambiguity and change. Companies merge and break apart regularly. Technology transforms work at a dizzying pace. People who have mastered their emotions are able to roll with the changes. When a new program is announced, they don’t panic; instead, they are able to suspend judgment, seek out information, and listen to the executives as they explain the new program. As the initiative moves forward, these people are able to move with it.

Sometimes they even lead the way. Consider the case of a manager at a large manufacturing company. Like her colleagues, she had used a certain software program for five years. The program drove how she collected and reported data and how she thought about the company’s strategy. One day, senior executives announced that a new program was to be installed that would radically change how information was gathered and assessed within the organization. While many people in the company complained bitterly about how disruptive the change would be, the manager mulled over the reasons for the new program and was convinced of its potential to improve performance. She eagerly attended training sessions—some of her colleagues refused to do so—and was eventually promoted to run several divisions, in part because she used the new technology so effectively.

I want to push the importance of self-regulation to leadership even further and make the case that it enhances integrity, which is not only a personal virtue but also an organizational strength. Many of the bad things that happen in companies are a function of impulsive behavior. People rarely plan to exaggerate profits, pad expense accounts, dip into the till, or abuse power for selfish ends. Instead, an opportunity presents itself, and people with low impulse control just say yes.

By contrast, consider the behavior of the senior executive at a large food company. The executive was scrupulously honest in his negotiations with local distributors. He would routinely lay out his cost structure in detail, thereby giving the distributors a realistic understanding of the company’s pricing. This approach meant the executive couldn’t always drive a hard bargain. Now, on occasion, he felt the urge to increase profits by withholding information about the company’s costs. But he challenged that impulse—he saw that it made more sense in the long run to counteract it. His emotional self-regulation paid off in strong, lasting relationships with distributors that benefited the company more than any short-term financial gains would have.

The signs of emotional self-regulation, therefore, are easy to see: a propensity for reflection and thoughtfulness; comfort with ambiguity and change; and integrity—an ability to say no to impulsive urges.

Like self-awareness, self-regulation often does not get its due. People who can master their emotions are sometimes seen as cold fish—their considered responses are taken as a lack of passion. People with fiery temperaments are frequently thought of as “classic” leaders—their outbursts are considered hallmarks of charisma and power. But when such people make it to the top, their impulsiveness often works against them. In my research, extreme displays of negative emotion have never emerged as a driver of good leadership.
