Saving money and saving lives*

Cass Sunstein

Every day we make choices—about what to buy or eat, about investments, about our children’s health and education, even about the causes we champion or the planet itself. Unfortunately, we often choose poorly. Nudging is a way to improve those choices. By knowing how people think, we can use sensible “choice architecture” to nudge people toward the best decisions for themselves, their families, and their society, without restricting their freedom of choice.




You aren’t at the mercy of your emotions—your brain creates them

Lisa Feldman Barrett

Can you look at someone’s face and know what they’re feeling? Does everyone experience happiness, sadness and anxiety the same way? What are emotions anyway? For the past 25 years, psychology professor Lisa Feldman Barrett has mapped facial expressions, scanned brains and analyzed hundreds of physiology studies to understand what emotions really are. She shares the results of her exhaustive research— and explains how we may have more control over our emotions than we think.



Choice blindness

Petter Johansson

We think we know why we do as we do. Through his research on choice blindness, Petter Johansson and his research group shows that this is not always the case. As cognitive scientist at Lund University and a Fellow at Swedish Collegium for Advanced Study, Uppsala, he studies choice blindness and preference change using methods ranging from questionnaires to close- up card magic.



How political biases affect your perception of science

Anthropologist and Global Change Maker Tinna Nielsen shares 11 ways you can outsmart your brain and be a better leader.



The history of human emotions

Tiffany Watt Smith

The words we use to describe our emotions affect how we feel, says historian Tiffany Watt Smith, and they’ve often changed (sometimes very dramatically in response to new cultural expectations and ideas. Take nostalgia, for instance: first defined in 1688 as an illness and con- sidered deadly, today it’s seen as a much less serious affliction. In this fascinating talk about the history of emotions, learn more about how the language we use to describe how we feel continues to evolve—and pick up some new words used in different cultures to capture those fleeting feelings in words.



Acting more rational – changing our automatic behavior

Ashley Zahabian

Our feelings naturally determine our behavior, but learning to become aware and change our behavior for a better outcome takes emotional intelligence. How can we learn and increase emotional intellect? Ashley Zahabian teaches us two practical ways we can all biologically and actively change the way we behave for better outcomes, and how we can think more clearly and rationally towards life success.




The power of decision-making

Benedikt Ahlfeld

Every day we make 20.000 decisions. Most of them with lightning speed; brain research proves that. The least of them, on the other hand, are rational and well thought through; the behav- ioral economy shows that. Benedikt Ahlfeld reveals which three decision traps you should certainly avoid and how you can utilize the findings of brain research.



Green nudges

Robert Böhm

In his talk, Robert Böhm explains how so-called “green nudges” can help to improve human be- haviour towards climate and environmental protection, without changing economic incentives or using any form of coercion. Moreover, he provides an insight into some of his research and the astonishing results.



The science of altruism

Dustin Daniels

Do you really know why you do what you do?

Petter Johansson

Experimental psychologist Petter Johansson researches choice blindness— a phenomenon where we convince ourselves that we’re getting what we want, even when we’re not. In an eye-opening talk, he shares experiments (designed in collaboration with magicians! that aim to answer the question: Why do we do what we do? The findings have big implications for the nature of self-knowledge and how we react in the face of manipulation. You may not know yourself as well as you think you do.

Can prejudice ever be a good thing?

Paul Bloom

We often think of bias and prejudice as rooted in ignorance. But as psychologist Paul Bloom seeks to show, prejudice is often natural, rational … even moral. The key, says Bloom, is to understand how our own biases work—so we can take control when they go wrong.



How to make hard choices

Ruth Chang

Here’s a talk that could literally change your life. Which career should I pursue? Should I break up—or get married?! Where should I live? Big decisions like these can be agonizingly difficult. But that’s because we think about them the wrong way, says philosopher Ruth Chang. She offers a powerful new framework for shaping who we truly are.



Minds and markets

Paul Craven

Paul Craven is a coach, consultant and public speaker in the area of Behavioural Economics. His talk on “The Mind, Markets and Magic” reveals why human beings have hardwired biases and often make ‘mental shortcuts’ – whether in the field of finance, more broadly in life or even when watching a magician. With 27 years investment experience at Schroders, PIMCO and most recently Goldman Sachs, and as a lover of history, Paul’s talk highlights some of the key biases shown by investors, as seen, for example, in stockmarket bubbles. As a member of the exclusive Magic Circle, Paul appreciates how the mind can play tricks, and delivers a talk that is highly interactive with the audience. He concludes by offering practical advice on how firms and individuals can use behavioural economics for their competitive advantage.



The psychology of your future self

Dan Gilbert

“Human beings are works in progress that mistakenly think they’re finished.” Dan Gilbert shares recent research on a phenomenon he calls the “end of history illusion,” where we somehow imagine that the person we are right now is the person we’ll be for the rest of time. Hint: that’s not the case.

BE BRIGHT: “Overcome your fear of making a mistake. Take a bold stance, an active role in big life situations. Calculate the risk, and take control!”



The decline of consumer irrationality

Itamar Simonson

Stanford professor Itamar Simonson spent much of his career showing that consumers tend to act irrationally and their preferences are highly malleable. But a few years ago he started having second thoughts in light of the Internet and the changing consumer environment. In this talk he will discuss the rise in consumer rationality and the decline of current marketing mantras about branding and loyalty. Contrary to the now prevalent belief that consumers usually make irrational decisions and can be easily influenced (which he helped establish), Simonson will show how everything changes when consumers base their decisions on reviews from other users, easily accessed expert opinions, price comparison apps, and other emerging technologies. Instead of relying on often unreliable proxies such as brand names, prior experience and loyalty, or price, consumers can make decisions based on the products’ “Absolute Value.” Based on his new book Absolute Value (with Emanuel Rosen) Simonson will present the far reaching implications of the changes in consumer decision making for marketing and management, including positioning, persuasion, market research, and influence more generally.



Can emotions influence our economic decision making

Ágnes Virlics

She completed her Ph.D. in Economics and her field of research is behavioral economics. Ágnes spent two semesters at the Faculty of Economics of the University of Cambridge, in the United Kingdom, as a visiting Ph.D. student. She investigates the psychological influences on economic decision making: why do people make their economic decisions the way they do it.

She creates her own mathematical model, which is a simulation of the interaction between rational objectivity and emotional subjectivity in economic decision making. During her research, Ágnes tested in practice the idea behind the model on a sample of decision makers, and she also conducted an economic laboratory experiment to study the effects of mood on investment decision making.




When you’re making a deal, what’s going on in your brain?*

Colin Camerer

When two people are trying to make a deal— whether they’re competing or cooperating— what’s really going on inside their brains?

Design to nudge and change behaviour

Sille Krukow

Today human behaviour is the biggest threat to mankind. We keep overeating, even though we know it´s bad for us. We keep using to much energy, even though we know the planet can’t keep up with our consumption. We keep driving too fast, even though we know it kills us. But this doesn’t mean that we have no intentions to change. We do. But changing actual human behaviour calls for good design solutions that take basic human instincts, flaws and habits into consideration. That is design to nudge.



How behavioral science can lower your energy bill*

Sometimes it’s good to give up the driver’s seat

Baba Shiv

Over the years, research has shown a counterintuitive fact about human nature: Sometimes, having too much choice makes us less happy. This may even be true when it comes to medical treatment. Baba Shiv shares a fascinating study that measures why choice opens the door to doubt, and suggests that ceding control—especially on life-or-death decisions—may be the best thing for us.




Saving for tomorrow, tomorrow*

Shlomo Benartzi

The Happy Planet Index

Nic Marks

Statistician Nic Marks asks why we measure a nation’s success by its productivity—instead of by the happiness and well-being of its people. He introduces the Happy Planet Index, which tracks national well-being against resource use (because a happy life doesn’t have to cost the earth. Which countries rank highest in the HPI? You might be surprised.



A monkey economy as irrational as ours*

Laurie Santos

Laurie Santos looks for the roots of human irrationality by watching the way our primate relatives make decisions. A clever series of experiments in “monkeynomics” shows that some of the silly choices we make, monkeys make too.



Sweat the small stuff*

Rory Sutherland

It may seem that big problems require big solutions, but ad man Rory Sutherland says many flashy, expensive fixes are just obscuring better, simpler answers. To illustrate, he uses behavioral economics and hilarious examples.




Our buggy moral code*

Dan Ariely

Behavioral economist Dan Ariely studies the bugs in our moral code: the hidden reasons    we think it’s OK to cheat or steal (sometimes). Clever studies help make his point that we’re predictably irrational—and can be influenced in ways we can’t grasp.



Teach statistics before calculus!

The psychology of time

Philip Zimbardo

Psychologist Philip Zimbardo says happiness and success are rooted in a trait most of us disregard: the way we orient toward the past, present and future. He suggests we calibrate our outlook on time as a first step to improving our lives.




Are we in control of our own decisions?*

Dan Ariely

Behavioral economist Dan Ariely, the author of Predictably Irrational, uses classic visual illusions and his own counterintuitive (and sometimes shocking) research findings to show how we’re not as rational as we think when we make decisions.



The psychology of evil

Philip Zimbardo

Philip Zimbardo knows how easy it is for nice people to turn bad. In this talk, he shares insights and graphic unseen photos from the Abu Ghraib trials. Then he talks about the flip side: how easy it is to be a hero, and how we can rise to the challenge.
