Power: Why Some People Have It and Others Don't

Jeffrey Pfeffer has taught organisational behaviour at Stanford's Graduate School of Business for over four decades. Power is the distillation of that teaching, drawn from his course called Paths to Power, brought to a wider audience. It is not a comfortable book. Pfeffer makes no effort to reconcile what he finds with what we wish were true.

His core argument: the leadership industry has built a mythology around performance, authenticity, and servant leadership that does not reflect how organisations actually work. Leaders who believe in that mythology are not moral. They are naive. And naivety, in Pfeffer's world, has a cost paid not just by the individual but by the people and causes they could have served with more power.

Power is not a book about becoming ruthless. It is a book about becoming clear. Pfeffer does not tell you to abandon your values. He tells you that values without power are ineffective. The ability to get things done, to protect your people, and to change broken systems requires understanding the game that is already being played around you, whether you choose to see it or not.

The world is not fair. Performance does not reliably produce advancement, protection, or influence.

His second core claim: most leaders resist this reality because it conflicts with their self-image and the narratives organisations use to attract and retain people. The just-world phenomenon, the belief that good work will eventually be recognised and rewarded, keeps talented people disarmed in environments that reward something else entirely.

Pfeffer organises his argument around three questions: Why does power matter? What produces it? How do you acquire and sustain it? His answers are built on decades of social science research, not anecdote.

Pfeffer opens with a finding that stops most readers. Studies of British civil servants showed that job control and status predicted mortality from cardiovascular disease more strongly than physiological risk factors like obesity or blood pressure. Power is not just a career issue. It is a survival issue. Those with less control over their environment experience chronic stress, which degrades health over time. Understanding and building power is not self-serving. It is self-preserving. And crucially, it enables the protection of others.

Pfeffer's first chapter is titled 'It Takes More Than Performance' and he means it literally. He documents organisations where poor performers kept their jobs because they managed relationships effectively, and high performers were eliminated because they neglected politics or alienated the wrong people. The key insight: your relationship with your direct manager is often more predictive of your position than your measurable results. Keep your boss happy and performance may not matter much. Upset them and performance will not save you.

Pfeffer identifies seven personal qualities that drive influence, distinct from technical competence: ambition and energy, focus, self-knowledge, confidence, empathy with others, capacity to tolerate conflict, and the ability to read and navigate social dynamics. These are not fixed personality traits. They are learnable capacities. The most frequently overlooked is conflict tolerance. Leaders who avoid disagreement, smooth over tension, and prioritise harmony above all else surrender power to those who do not.

One of Pfeffer's sharpest observations: perception operates independently of reality in organisations, and it compounds over time. A leader known as powerful becomes more powerful because of that perception alone. A leader perceived as marginal loses influence regardless of their performance. Managing reputation is not vanity. It is a structural requirement for anyone who wants to retain the capacity to act. Pfeffer calls this building a brand and is explicit that it requires deliberate effort: visibility, narrative, and consistency of behaviour in high-stakes moments.

Pfeffer is direct about networking: it is not optional for those who want to influence at scale. Weak ties, which are acquaintances and peripheral relationships, are often more valuable than close relationships because they provide access to different information flows and coalitions. The deeper point is about structural position: leaders who are nodes in multiple networks have more influence than those embedded deeply in just one. The ability to bridge across groups is a source of political power that most leaders systematically underestimate.

Pfeffer's book is most useful not as a manual but as a diagnostic. It reveals where leaders are operating with blind spots that cost them and their organisations.

You may be operating with a performance-only model if your best work is consistently underrecognised, if you feel frustrated that politics is rewarding the wrong people, or if you believe your results will eventually speak for themselves without deliberate visibility management.

You may be neglecting reputation infrastructure if your influence is limited to your direct team, if you are rarely consulted on decisions outside your formal remit, or if you have not consciously built relationships with the people who control resources, access, and opportunity.

You may be conflict-avoidant at a political cost if you consistently smooth over disagreements that need to be surfaced, if you choose harmony over honesty in high-stakes situations, or if you have ceded territory to more aggressive colleagues rather than holding a position you believed in.

The belief that organisations are meritocracies is not just empirically questionable. It is psychologically dangerous. It creates passivity in leaders who believe their work will eventually be recognised, and it creates cognitive dissonance when the system fails to deliver. Pfeffer argues this belief must be consciously examined and set aside in order to operate effectively in real organisations.

Many high-integrity leaders resist self-promotion on principle. Pfeffer does not ask you to abandon that principle, but he documents its cost. In environments where visibility drives opportunity, choosing not to claim credit or build a public profile is not humility. It is an economic decision that reduces your capacity to act. The resolution is not bragging. It is strategic visibility: ensuring that your work and your thinking are known to the people with the power to amplify them.

Pfeffer includes a chapter on demeanour, voice, and physical presence as components of political effectiveness. Leaders who speak tentatively, over-qualify statements, or defer excessively communicate less power than they may hold. This is not about performance in the theatrical sense. It is about the signal your manner sends regarding your own confidence in your position, and the way that signal shapes others' assessments of your authority.

One of the book's most practically useful sections: Pfeffer studies how leaders recover from political reversal. His finding is counterintuitive. Those who treat setbacks as permanent or defining, who publicly show damage, tend to experience cascading loss of influence. Those who treat setbacks as tactical situations to be managed, who remain composed and continue to operate with apparent confidence, retain more of their power base than the severity of the setback would suggest is possible.

Pfeffer addresses the moral dimension directly, and his answer is nuanced. He does not argue that all political behaviour is ethical. He argues that the refusal to engage with power on ethical grounds often produces less ethical outcomes, because it cedes the field to those with fewer scruples. The ethical case for political engagement is not that the ends justify the means. It is that those who care about ends must be willing to understand the means.

This book directly develops two core leadership capacities.

Political Maturity: the ability to see and navigate the informal power structures of an organisation without being corrupted by them. Pfeffer provides the diagnostic framework. The practitioner work is in applying it to your own context.

Influence Architecture: the deliberate construction of the relationships, reputation, and visibility that allow a leader to act beyond their formal authority. Most leaders wait until they need influence to build it. Pfeffer argues it must be built long before it is needed.

Identify the three decisions that will most impact your work in the next six months. For each decision, map who has formal authority, who has informal influence, and who you currently have a relationship with in both groups. The gaps are your political risk register.

List your five most significant contributions in the past quarter. Ask for each: who beyond your immediate team knows about this? If the answer is fewer than five people with influence, you have a visibility gap. Identify one specific action per contribution to close that gap.

Name one situation in the last 30 days where you chose harmony over honesty. Where you let something go that you believed needed to be challenged. What was the cost? What would it take to re-open that conversation? Political clarity begins with naming what you have been avoiding.

Ask yourself: what is the one word or phrase that people most closely associate with me in this organisation? Is that the word you want? If not, what would need to change in your behaviour, visibility, and communication to shift that perception?

Pfeffer's Power is not a book for people who want permission to be ruthless. Most of those people do not need permission. It is a book for leaders of integrity who have been operating with one hand behind their back. Who have believed that good work, good values, and good intentions were sufficient armour in complex organisations.

They are not. And the consequences of that belief are not paid only by the leader. They are paid by every team that went unprotected, every initiative that died without a champion who understood the room, and every culture that calcified because no one who cared had the power to change it.

Political clarity is not the opposite of character. It is what character requires to be effective. Pfeffer gives you the diagnosis. What you do with it is your leadership decision.
