Power, at its most basic, is the ability to influence outcomes, whether that means changing someone’s behavior, shaping what they believe, or controlling the resources they depend on. But the nature of power is far more layered than any single definition suggests. It operates through force, persuasion, social structures, personal relationships, and even the algorithms that curate your news feed. Understanding how power actually works requires looking at it from several angles: who holds it, how they got it, what it does to them, and how it shapes the people around them.
Power as Control Over Others
The most straightforward way to think about power is as one person’s ability to get what they want, even when others resist. Max Weber, the sociologist whose definition still anchors most discussions of power, described it as “the probability that one actor within a social relationship will be in a position to carry out his own will despite resistance.” This is the kind of power most people recognize immediately: a boss who can fire you, a government that can jail you, a parent who can ground you.
But power doesn’t always look like open conflict. Michel Foucault argued that power also works invisibly, shaping people’s behavior before they even realize it. His famous example was the Panopticon, a prison designed so that inmates could be watched at any time without knowing whether they were being observed. The prisoners eventually policed themselves. Foucault saw this dynamic everywhere in modern life: in schools, workplaces, hospitals, and social norms that train people to behave in certain ways without anyone explicitly giving orders.
Pierre Bourdieu added another layer. He described how people internalize the rules of their social environment so deeply that they follow them automatically, without conscious thought. He called this internalized set of habits and expectations “habitus.” A person raised in poverty and a person raised in wealth don’t just have different bank accounts. They carry different assumptions about what’s possible, what’s appropriate, and what they deserve. That invisible programming is itself a form of power, one that reproduces inequality without anyone needing to enforce it directly.
The Five Bases of Social Power
In the late 1950s, psychologists John French and Bertram Raven identified five distinct sources that give one person influence over another. Their framework remains one of the most widely used models for understanding power in organizations, families, and everyday interactions:
- Reward power: the ability to offer something someone wants, like a raise, praise, or a favor.
- Coercive power: the ability to punish, whether through firing, fines, social exclusion, or physical force.
- Legitimate power: authority that comes from a recognized role or position, like a judge, a teacher, or a police officer.
- Referent power: influence that comes from being admired or identified with. A celebrity endorsing a product, or a friend whose opinion you value, exercises referent power.
- Expert power: influence based on specialized knowledge or skill. You follow your doctor’s advice not because they can punish you, but because they know more about medicine than you do.
What makes this framework useful is that it reveals how different types of power produce very different responses. Coercive power generates compliance but also resentment. Expert and referent power tend to produce genuine buy-in. Most real-world power dynamics involve several of these bases operating simultaneously.
Power in Personal Relationships
Power doesn’t just exist in governments and corporations. It shapes intimate relationships in ways that are often invisible to the people involved. Resource theory, a framework developed by sociologists studying marriages and partnerships, suggests that power within a relationship flows toward whoever controls more resources. Those resources include income, education, and occupational prestige, but also subtler factors like who has better alternatives if the relationship ends.
Partners who hold more socioeconomic resources typically have greater influence over finances, household decisions, and even who gets the “final say” on major life choices. This dynamic helps explain why financial dependence has historically been a tool of control: when one partner earns all the income, the other partner’s ability to negotiate, disagree, or leave is fundamentally constrained. But resources aren’t only financial. Emotional investment matters too. The person who cares less about whether a relationship continues often holds more power within it, simply because they have less to lose.
Hard Power, Soft Power, and Global Influence
On the world stage, power takes two broad forms. Hard power is the ability to coerce, and it grows out of a country’s military and economic strength. Sanctions, trade restrictions, and military intervention are all exercises of hard power. Soft power, a concept developed by political scientist Joseph Nye at Harvard, works through attraction rather than coercion. It arises from the appeal of a country’s culture, political ideals, and policies.
The distinction matters because hard power and soft power accomplish different things. Hard power remains essential in a world where states guard their independence and non-state groups turn to violence. But soft power is what prevents extremists from recruiting supporters among moderates, and it’s what enables the multilateral cooperation needed to address global challenges like climate change or pandemics. The most effective approach, which Nye calls “smart power,” combines both: the credible threat of force alongside the cultural and diplomatic appeal that makes other nations want to cooperate rather than resist.
Digital platforms have added a new dimension to this equation. Governing platforms like TikTok and YouTube is now inseparable from governing world order, because international politics increasingly lives in digital feeds. Algorithmic systems decide what billions of people see, creating a form of structural power that doesn’t belong to any single government or leader. Debates over data localization, algorithmic audits, and platform regulation are fundamentally debates about who controls this new source of influence.
What Power Does to the People Who Hold It
One of the most consistent findings in psychology is that power changes the people who acquire it, and not usually for the better. More than 20 years of research led by psychologist Dacher Keltner at UC Berkeley has shown that people in positions of power tend to become less empathetic, more entitled, and quicker to behave unethically compared to people with less power or wealth.
The findings are striking in their specificity. In a 2012 field study led by psychologist Paul Piff, drivers of high-end cars like BMWs and Mercedes were four times more likely to cut off other vehicles at a busy intersection and three times more likely to cut off a pedestrian at a crosswalk, compared to drivers of less expensive cars. In the same study, wealthier participants helped themselves to twice as much candy that had been set aside for children. A separate 2011 study led by psychologist Jennifer Stellar found that upper-middle and upper-class participants were measurably less able to feel empathy and compassion for people in distress.
Keltner describes this as the “power paradox.” People typically gain power by being attuned to others, listening carefully, and adapting their behavior to the group. But once they have power, their focus shifts inward. “We become focused on our desires,” Keltner explains, “and that focus produces a state of mania.” The very skills that earned them influence erode once they achieve it.
When Power Becomes Pathological
Taken to its extreme, long-term power can produce what researchers have proposed calling “hubris syndrome,” a personality change that develops specifically after a person achieves overwhelming success or gains considerable power. Unlike narcissistic personality disorder, which typically emerges in early adulthood, hubris syndrome appears later in life as a direct consequence of holding power.
The proposed diagnostic criteria include grandiosity, feelings of entitlement, condescension toward others, impulsivity, recklessness, and a lack of planning. Five symptoms are considered unique to the syndrome: identifying so completely with an organization or nation that the leader sees no distinction between their personal interests and the institution’s; speaking in the third person or using the royal “we”; an unshakable belief they’ll be vindicated; restlessness and impulsiveness; and a tendency to let their “broad vision” about the moral rightness of a course of action override any practical concerns about cost or consequences. The personality change must persist for at least three months and represent a clear departure from the person’s previous character.
Hubris syndrome hasn’t yet been formally added to psychiatric classification systems, but the proposal highlights something important about the nature of power: it isn’t just a tool people use. It’s a force that reshapes the people who wield it, often in ways they’re the last to notice.
Power as Structure, Not Just Choice
Perhaps the deepest insight about the nature of power is that much of it operates without anyone consciously wielding it. Social structures, economic systems, cultural norms, and now algorithms all distribute advantages and disadvantages in ways that feel natural to the people living inside them. A person born into a wealthy family doesn’t need to dominate anyone to benefit from structural power. The systems around them, from school funding formulas to hiring networks to inheritance laws, do the work automatically.
This is what makes power so difficult to see clearly. The most visible kind, one person giving orders to another, is actually the least common form. The deeper forms of power shape what options are available, what feels normal, what seems possible, and what never even occurs to you to question. Recognizing those layers is the first step toward understanding how power actually operates in your life, whether you hold it, lack it, or, as is usually the case, experience some complicated mix of both.
