Bio

About Cass Sunstein

Cass Sunstein has advised the United Nations, the European Commission, the World Bank and the United Kingdom's Behavioural Insights Team. "Core commonalities, like how people dislike losses more than they like gains or why people all over the world make the same mistakes about risk, are at the core of our species," he says.

He has lately turned to algorithms and AI, examining how they can improve human judgment. "What's also interesting is what algorithms can't do, like predict romantic attraction or if a joke will land," he notes.

It’s hard to imagine our world without its stars, icons, influencers and celebrities – the rich and famous that flood our media. They’re part of our culture and history, seeming permanent and preordained. That’s far from the case, as Harvard Law professor Cass Sunstein shows in his book “How to Become Famous.” Focusing on both famous and forgotten (or simply overlooked) artists and luminaries in music, literature, business, science, politics and other fields, he explores why some individuals become famous and others don’t and offers a new understanding of the roles played by greatness, luck and contingency in the achievement of fame. With lessons for marketers, executives and leaders alike, Sunstein examines recent research on informational cascades, network effects and group polarization to probe the question of how people become famous. He leads audiences on a fun, captivating and at times profound journey that will forever change your perspective on the latest celebrity’s “fifteen minutes of fame” and on what vaults some to the top — and leaves others in the dust.

While polarization is an age-old problem, managing and governing people in the 21st century has been complicated by increasingly divisive rhetoric within online and in-person groups, creating damaging political and social divisions in every corner of the world. Business and government leaders looking for successful ways to bridge those divides will find Harvard Law School professor Cass Sunstein’s insights invaluable. In this presentation, he shares the results of experiments he’s conducted, which explain why such divides exist. He then outlines methods leaders can employ to promote unity, understanding and, ultimately, a successful way forward to solve common problems and reach common goals.

Have you ever noticed that what is thrilling on Monday tends to become boring on Friday? Even exciting events and objects lose their sparkle after a while. People stop noticing what is most wonderful in their own lives, and they also stop noticing what is terrible – they get used to dirty air, stay in unhealthy relationships, grow to accept authoritarianism and take foolish risks. But, asks Harvard Law professor Cass Sunstein, what if we could find a way to see everything anew and regain sensitivity, not only to the great things in your life, but also to the terrible things you stopped noticing and so you don’t try to change? In a groundbreaking study, encapsulated in his book “Look Again,” Sunstein and his co-author investigate why we stop noticing both the great and not-so-great things around us and how to “dishabituate” at the office, in the bedroom, at the store, on social media and in the voting booth. Based on decades of research in the psychological and biological sciences, he illuminates how to refresh your perspective, allowing you to more clearly identify the bad, and more deeply appreciate the good.

Human beings are sometimes “biased,” in the sense that they make systemic mistakes (for example, they might show “optimistic bias”). In addition, human beings are sometimes “noisy,” in the sense that they show unwanted variability (perhaps making different decisions in the morning and the afternoon). The best solution to both noise and bias, says Harvard Law School professor Cass Sunstein, comes from “decision hygiene,” which can include the use of formal models and algorithms. In this presentation based on his award-winning book “Noise: A Flaw in Human Judgement” (2021), Sunstein illuminates concrete ways to reduce or even eliminate widespread “algorithm aversion.”

Generative AI has led to the definition of “sentience” becoming more of a question than a statement. If AI tools can “think,” should they have rights? No more than your toaster should have rights, says Harvard Law professor Cass Sunstein, a prominent legal scholar and well-known authority on the U.S. Constitution. Funny and engaging, Sunstein uses accessible metaphors and pop culture references to illustrate what generative AI is, how it works and why, even though it seems humanlike in its interactions, it doesn’t deserve any more rights than a blanket on a bed. Sunstein brings organizations thought-provoking questions that encourage deeper thinking about how to engage with AI technology, no matter how quickly it advances.

Testimonials

How should we choose when our values might change as a result of our choice? Or when we have limited time to assess the options? How should we decide what we want to learn and what we ought to believe? In 'Decisions about Decisions', Sunstein presents a rich and diverse set of reflections on these and other questions about how we do, and should, decide how to make the choices that fill our lives. The prose is clear and engaging; the essays packed with illuminating and accessible examples; the thought deeply informed throughout by Sunstein’s broad knowledge of behavioral economics, public policy, legal theory, and philosophy.
