The illusion of power

We chase power because we think it gives us control. A bigger title, a wider scope of authority, more people reporting to us. But the relationship between power and control is far more fragile than it appears. Research in psychology and neuroscience suggests that the experience of power doesn't just fail to deliver the control we expect, it actively distorts our ability to perceive reality, read other people, and make sound decisions. The illusion of power isn't that power doesn't exist. It's that the things power promises, certainty, influence, safety, are often mirages that dissolve the moment we try to grasp them.

The illusion of control

In 1975, psychologist Ellen Langer published a landmark paper in the Journal of Personality and Social Psychology that introduced the concept she called the "illusion of control." Through a series of six experiments involving over 600 participants, she demonstrated that when elements of skill, such as competition, choice, familiarity, and personal involvement, were introduced into situations governed entirely by chance, people behaved as though they could influence the outcome. In one study, participants who were allowed to choose their own lottery ticket valued it more highly than those who were assigned one, even though both tickets had identical odds. In another, participants who competed against a nervous opponent bet more confidently than those facing a confident one, despite the game being pure chance. Langer's insight was simple but profound: we don't just want control, we manufacture the feeling of it, even where none exists. This finding has been replicated and extended many times since. A particularly striking example comes from the streets of New York City. In the 1970s, the city installed pedestrian buttons at traffic light intersections. Signs instructed people to push the button and wait for the walk signal. New Yorkers dutifully pressed the buttons for decades, believing they were influencing the lights. In reality, since the late 1980s, the city's traffic signals had been controlled by a centralized computer system. The buttons did nothing. But the city never removed them, and people kept pressing.

What power does to the brain

If the illusion of control affects everyone, it hits people in positions of power even harder. A study from the Association for Psychological Science found that when high-power participants were offered a dice game with a reward for predicting the outcome, every single person in the high-power group chose to roll the dice themselves, compared to less than 70% of those in low-power or neutral groups. Simply feeling powerful was enough to make people believe they could influence a random outcome through their own actions. But the effects go deeper than overconfidence. In a 2017 article for The Atlantic, journalist Jerry Useem explored research suggesting that power can cause something resembling brain damage. Neuroscientist Sukhvinder Obhi at McMaster University found that people who had been primed to feel powerful showed impaired "mirroring," the neural process that underpins empathy and our ability to read other people. In other words, power dampened the very cognitive faculty that likely helped those people rise to positions of influence in the first place. This isn't just a laboratory curiosity. Lord David Owen, a neurologist and former British Foreign Secretary, studied the records of US Presidents and UK Prime Ministers over a hundred-year period. Together with psychiatrist Jonathan Davidson, he identified a pattern he called "hubris syndrome," an acquired personality change triggered by the experience of power and sustained success. Its symptoms include a grandiose sense of self, a belief in being always right, contempt for others' opinions, and increasingly reckless decision-making. Critically, hubris syndrome is not a lifelong personality disorder like narcissism. It's acquired. It develops after a person assumes power, and it tends to diminish when the power goes away. Power doesn't just reveal character, it reshapes it.

The feedback loop that breaks

One of the most dangerous aspects of power is how it distorts the information environment around the person who holds it. A Columbia University study found that power changes how we perceive others. When we feel powerful, others appear less competent and less capable. This perception gap makes it easier to dismiss dissenting views, and harder to notice when you're wrong. The result is a feedback loop that gradually breaks down. Early in a leader's tenure, they tend to seek input, listen carefully, and calibrate their decisions against reality. Over time, success reinforces confidence. Advisors learn to tell the leader what they want to hear. Critics are sidelined. The leader's model of reality becomes increasingly self-referential, a closed system where the only input that survives is the input that confirms existing beliefs. This is what makes power so paradoxical. The more of it you accumulate, the less accurate your picture of the world becomes. And the less accurate your picture, the worse your decisions, even as your confidence in those decisions grows.

The Stoic correction

The ancient Stoics understood this dynamic intuitively, long before anyone had the language of cognitive bias or neuroscience to describe it. Marcus Aurelius, writing in his Meditations as the most powerful man in the Roman Empire, repeatedly reminded himself of the limits of his own influence. "You have power over your mind, not outside events," he wrote. "Realize this, and you will find strength." For Marcus, real power wasn't the ability to bend the world to your will. It was the discipline to focus only on what was genuinely within your control: your own judgments, responses, and character. Epictetus, who spent part of his life as a slave before becoming one of the most influential philosophers in history, built his entire framework around this distinction. He divided all things into what is "up to us" (our opinions, desires, and actions) and what is "not up to us" (our reputation, our body, external events). The path to freedom, he argued, was not to gain power over the external world, but to stop confusing external circumstances with things you can actually control. The Stoic insight maps neatly onto Langer's research. We suffer when we cling to illusions of control over things that are fundamentally outside our influence. And the more power we gain, the stronger those illusions become.

The leader's dilemma

None of this means power is inherently bad, or that leadership is a trap. But it does mean that exercising power well requires a kind of deliberate self-awareness that cuts against our natural instincts. The leaders who avoid hubris syndrome tend to share a few traits. They maintain close relationships with people who are willing to disagree with them. They build systems that surface uncomfortable truths rather than filtering them out. They treat their own certainty as a signal to pause rather than to act. And they remain genuinely curious about the perspectives of people who have less power than they do. Professor David Zweig at the University of Toronto puts it bluntly: leaders who cling to the belief that every aspect of an employee's work can be fully controlled are "doomed to fail." The alternative isn't giving up on leadership. It's giving up on the illusion that leadership means control.

What to take from this

Power is a tool, not a truth. It can amplify your ability to act, but it can also amplify your blind spots. The research is clear: the experience of having power reliably produces overconfidence, reduced empathy, and distorted perception. The practical takeaway isn't to avoid power, but to hold it lightly. To build in checks against your own biases. To remember that the feeling of being in control is not the same as actually being in control. And to recognize that the most important form of power, the power over your own mind and responses, is the one that no title, no org chart, and no amount of authority can give you. The buttons on the crosswalk don't do anything. But we keep pressing them anyway. The question is whether we're willing to notice.
