About Dan Ariely

Dan Ariely is a renowned psychologist and behavioral economist, known for his insightful studies on human decision-making and motivation.

He earned his B.S. in cognitive psychology from the Hebrew University of Jerusalem, an M.A. in cognitive psychology from the University of Arizona, and a Ph.D. in cognitive psychology from the University of North Carolina at Chapel Hill. Influenced by the works of renowned psychologists such as Daniel Kahneman, Amos Tversky, and Herbert A.

His major works include "Predictably Irrational" (2008), "The Upside of Irrationality" (2010), "The Honest Truth about Dishonesty" (2012), and "Irrationally Yours: A Wise-Cracking Guide to the Hidden Forces that Shape Our Lives" (2021).

He is a James B. Duke Professor of Psychology and Behavioral Economics at Duke University and a founding member of the Center for Advanced Hindsight. In 2013, Ariely was named one of the top 10 most influential people in the world by Time magazine. His work continues to inspire researchers, policymakers, and everyday individuals seeking to understand the complexities of human decision-making.

Interpretations of Popular Quotes

"People are rationalizers, not rational actors."

This quote suggests that individuals tend to justify their actions and decisions based on rational explanations rather than making decisions based on pure reason or logic (rational actors). People often construct post-hoc narratives to explain their choices, regardless of whether those choices were actually driven by rational considerations. In other words, people are more inclined to provide a rational explanation for their actions after the fact, rather than always making truly rational decisions in the moment. This insight highlights the importance of understanding the role of emotions, biases, and cognitive shortcuts in shaping human behavior.


"We're not as rational or logical as we think we are. We're much more emotional than we like to believe."

Dan Ariely's quote suggests that humans tend to overestimate our own rationality and logic, while underestimating the impact of emotions in decision-making. This implies that many of our choices are influenced by feelings rather than cold, calculated reasoning. Understanding this can help us approach life with more empathy, flexibility, and mindfulness, recognizing that our emotional state often plays a significant role in shaping our actions and judgments.


"I think one of the problems with our current understanding of free will is that it is based on an oversimplified model."

This quote by Dan Ariely suggests that our traditional conception of free will is overly simplistic, perhaps lacking in depth or complexity. He may be implying that we often view free will as a binary concept – either you have it or you don't – but in reality, it is likely far more intricate and multifaceted, influenced by various factors such as our environment, upbringing, cognitive biases, and unconscious processes. This perspective invites further exploration and understanding of the complexities surrounding the concept of free will.


"Humans are really good at making up stories about themselves and their actions, but they're not always very good at seeing things as they actually are."

This quote suggests that people have a strong tendency to construct narratives or beliefs about themselves and their behaviors. However, these self-crafted narratives may not always accurately reflect the objective reality of one's actions or character traits. Essentially, Ariely is highlighting our propensity for subjective self-perception, which might not align perfectly with how others view us or how events transpire in actuality.


"The biggest mistake we humans make is thinking we've understood something we haven't, and the next biggest is thinking we've understood something when we have."

This quote by Dan Ariely highlights the human tendency to overestimate our understanding of complex concepts or situations, leading to potentially harmful misconceptions. The first part of the quote underscores the danger in assuming familiarity with something that remains largely unknown, while the second part emphasizes the pitfall of mistaking shallow comprehension for true understanding. In essence, Ariely is reminding us to be humble in our pursuit of knowledge and strive for a deeper, more nuanced understanding before making assumptions or decisions based on flawed perceptions.


Because cheating is easier when we can justify our behavior, people often cheat in small amounts: We can come up with an excuse for stealing Post-It notes, but it is much more difficult to come up with an excuse for taking $10,000 from petty cash.

Dishonesty is all about the small acts we can take and then think, 'No, this not real cheating.' So if you think that the main mechanism is rationalization, then what you come up with, and that's what we find, is that we're basically trying to balance feeling good about ourselves.

It is helpful to think of people as having two fundamental motivations: the desire to see ourselves as honest, good people, and the desire to gain the benefits that come from cheating - on our taxes or on the football field.

In a world where everyone is behaving honestly, any dishonesty constitutes a big infraction. But, in a world where many people are behaving dishonestly, and the news is filled with stories of their infractions, even big infractions can feel small to the perpetrator.

In terms of the actual curriculum for management education, my own view is very simple-minded: The world is incredibly complex, it changes all the time, and we should not even hope that we could create a general model that accurately describes the world in all its possible states.

What kind of people would be able to rationalize better than other people? Better storytellers, right? Creative people, right? Because if you're creative, you find more ways to cheat and still yourself a story about why this is okay.

It is true that from a behavioral economics perspective we are fallible, easily confused, not that smart, and often irrational. We are more like Homer Simpson than Superman. So from this perspective it is rather depressing. But at the same time there is also a silver lining. There are free lunches!
