Johnstone Professor of Psychology, Harvard | Author, Better Angels, Enlightenment Now & When Everyone Knows | BBVA Frontiers of Knowledge Award
Steven Pinker is one of the most influential public intellectuals alive. The Johnstone Family Professor of Psychology at Harvard, he has written eleven books that have collectively redefined how educated people think about language, the mind, violence, progress, rationality, and human nature. His two most recent books make the case that the world is getting better and explain the cognitive and social architecture of common knowledge.

Steven Pinker is one of the most influential public intellectuals of the past three decades. The Johnstone Family Professor of Psychology at Harvard University, he has spent a career asking some of the most consequential questions about the human condition and answering them with a combination of empirical rigor and stylistic clarity that very few academics can match. His work has reshaped how educated people think about language, consciousness, violence, moral progress, rationality, and the nature of the mind — and his books have found audiences far beyond the academy, making him one of the rare scientists whose ideas genuinely change how non-scientists see the world.
As a science speaker, Pinker grew up in Montreal and earned his BA from McGill University and his PhD from Harvard, before holding faculty positions at Harvard, Stanford, and MIT. He has been elected to the National Academy of Sciences, the Royal Society of Canada, and the American Academy of Arts and Sciences, and has received honorary doctorates from universities across North America and Europe. He has won prizes for his research, his writing, and his teaching, including the William James Book Award, the George Miller Prize, the Troland Research Award, and the Henry Dale Prize. In 2024, the BBVA Foundation awarded him the Frontiers of Knowledge Award alongside philosopher Peter Singer for innovative academic contributions in the domains of rationality and moral progress that have achieved widespread impact in the public sphere.
Pinker has been named on the lists of the most influential people in the world by Time and Foreign Policy, and on lists of the most eminent psychologists of the modern era by academic surveys. He writes regularly for the New York Times, the Wall Street Journal, The Guardian, the New York Times Book Review, and the Harvard Crimson, and is a frequent presence in major media on questions of science, rationality, progress, and academic freedom.
Across eleven books, Pinker has built one of the most coherent and evidence-grounded bodies of popular intellectual work in contemporary non-fiction. The Language Instinct (1994) made the case that language is a biological faculty, not a cultural invention. How the Mind Works (1997) applied evolutionary psychology and computational theory to explain the design of the human mind. The Blank Slate (2002) mounted the most rigorous challenge to the then-dominant view that human nature is infinitely malleable. The Better Angels of Our Nature (2011) documented, with overwhelming data, the long-run decline of violence across human history. The Sense of Style (2014) reimagined the writing guide through the lens of cognitive science. Enlightenment Now (2018) extended the argument of Better Angels to the full range of human flourishing metrics, making the case for progress as both empirical fact and normative ideal.
His 2021 book Rationality: What It Is, Why It Seems Scarce, Why It Matters (Allen Lane/Viking) examines why supposedly rational beings are so consistently irrational, and how understanding the cognitive tools that lead us astray can help us use reason more effectively. His most recent book, When Everyone Knows That Everyone Knows…: Common Knowledge and the Mysteries of Money, Power, and Everyday Life (Scribner, 2025), introduces the concept of common knowledge — information that everyone knows that everyone knows — and shows how this recursive structure underlies phenomena as varied as bank runs, political revolutions, social taboos, humor, and the coordination problems that plague organizations. Nobel laureate Eric Maskin called it “an expository masterpiece.”
As a speaker, Steven Pinker delivers what very few people on earth can: a lifetime of synthetic intellectual work, made accessible without being simplified, on questions that matter to anyone trying to understand the world clearly.

Pinker's signature and most requested keynote presents the empirical case for human progress across 15 measures of wellbeing — life expectancy, health, food, wealth, safety, peace, democracy, equal rights, education, and more — and argues that the failure to recognize this progress is itself a problem with significant consequences for public policy and personal psychology. He examines why the human brain systematically underestimates progress, why the news media structurally misrepresents the state of the world, and why the Enlightenment values of reason, science, and humanism that produced the progress of the past two centuries are now under threat from both the left and the right. A keynote that reliably changes how audiences see the world they are operating in — and what they conclude is worth protecting.
If humans are rational beings, why do we fall for conspiracy theories, make predictable statistical errors, seek out information that confirms what we already believe, and allow emotion to override evidence in some of the highest-stakes decisions we make? Pinker examines the specific cognitive tools — logic, probability, Bayesian reasoning, causal inference, game theory, critical thinking — that make rationality possible, and the specific biases, motivated reasoning patterns, and social dynamics that make it hard. He presents a practical framework for how individuals and organizations can use the tools of rationality more deliberately, and examines why the current crisis of institutional trust and political polarization is, at its core, a rationality problem.
Drawing from his landmark 2011 book, Pinker presents what he calls the most important and least appreciated fact about human history: that violence has declined dramatically across every time scale, from prehistoric to modern, and across every category, from war and genocide to homicide, domestic abuse, child punishment, and the treatment of animals. He examines the historical and psychological forces that drove this decline — the Leviathan, commerce, feminization, cosmopolitanism, and the escalator of reason — and what the evidence says about which of these forces are now most at risk. A keynote that provides senior audiences with the deepest possible grounding in the trajectory of human civilization and what it implies for the challenges we face.
Pinker's most recent book introduces an idea that seems abstract but turns out to explain an astonishing range of human social phenomena. Common knowledge — information that everyone knows that everyone knows, to however many levels of recursion — differs from mere widespread knowledge in ways that are cognitively and socially consequential. When something becomes common knowledge, it changes behavior in ways that simple information does not: it enables coordination, forces acknowledgment, destroys plausible deniability, and triggers tipping points. Pinker shows how this explains bank runs, political revolutions, social taboos, #MeToo, humor, the persistence of bad organizational cultures, and why some truths that everyone privately believes cannot be stated publicly. A keynote that gives leaders a genuinely new lens for understanding communication, coordination, culture, and the moment when hidden consensus becomes public action.
