Lying about dishonesty….

Nov 19

This guy has been posting “social science experiments” like this one:

Sadly, these are not real experiments.  They have been hiring actors and filming their reactions as if they were real.  How sad.  See this interview.

Lying about dishonesty….




Last chance?

Nov 17
Our Kickstarter campaign ends very soon.

This might be your last chance to get the game:) 

And if you participated already, thanks, and we are looking forward to the next steps.



We just added a new type of card to the game.

Oct 28
One of the goals of our game was to seed a discussion about the lessons from different social science experiments.  We hoped that after players predicted different result, there will be a discussion around the table – what does this all say about us, and how can we make better decisions? In order to facilitate this discussion, but at the same time keep the game flowing and fun, we created a new type of card. It is a regular question card with a new section called “Best Practice”.
In this section, the player is not presented with a few possible results to an experiment, but with a few possible “Best Practice” behaviors, that if applied, can improve how we behave.
Do you want to guess the correct answers? Post your answer in the comments.

Just launched the Irrational Game

Oct 20

The day has finally come!

We’ve just launched the Irrational Game Kickstarter campaign, which means you can now get the game and some other rewards here.

The Irrational Game – We hope it will be a thought provoking, engaging and fun way to incorporate social sciences and human behavior into a challenging and strategic game.

It should also give you a way to reflect on your behavior and what you might want to change

If you consider supporting the project, please do it on the first day. A first day boost will give us great momentum for the entire campaign!

Thank you so much for all of your support. We can’t wait to get you the game.

Irrationally yours,



Investment Survey

Sep 08

Do you manage at least a portion of your own investments? If so, we have a survey studying investor behavior and could use your help. The survey contains questions about financial decision-making that’s part of a research study at Duke University. Please open the link below in a new window to take the survey. The survey should take you about 30 minutes. We would appreciate your full attention and careful consideration of each question. Participation is voluntary and your answers will remain anonymous. Thanks for participating!

The English are feeling the pinch in relation to recent events in Syria and have therefore raised their security level from “Miffed” to “Peeved.” Soon, though, security levels may be raised yet again to “Irritated” or even “A Bit Cross.” The English have not been “A Bit Cross” since the blitz in 1940 when tea supplies nearly ran out. Terrorists have been re-categorized from “Tiresome” to “A Bloody Nuisance.” The last time the British issued a “Bloody Nuisance” warning level was in 1588, when threatened by the Spanish Armada.

The Scots have raised their threat level from “Pissed Off” to “Let’s get the Bastards.” They don’t have any other levels. This is the reason they have been used on the front line of the British army for the last 300 years.

The French government announced yesterday that it has raised its terror alert level from “Run” to “Hide.” The only two higher levels in France are “Collaborate” and “Surrender.” The rise was precipitated by a recent fire that destroyed France ‘s white flag factory, effectively paralyzing the country’s military capability.

Italy has increased the alert level from “Shout Loudly and Excitedly” to “Elaborate Military Posturing.” Two more levels remain: “Ineffective Combat Operations” and “Change Sides.”

The Germans have increased their alert state from “Disdainful Arrogance” to “Dress in Uniform and Sing Marching Songs.” They also have two higher levels: “Invade a Neighbour” and “Lose.”

Belgians, on the other hand, are all on holiday as usual; the only threat they are worried about is NATO pulling out of Brussels .

The Spanish are all excited to see their new submarines ready to deploy. These beautifully designed subs have glass bottoms so the new Spanish navy can get a really good look at the old Spanish navy.

Australia, meanwhile, has raised its security level from “No worries” to “She’ll be alright, Mate.” Two more escalation levels remain: “Crikey! I think we’ll need to cancel the barbie this weekend!” and “The barbie is cancelled.” So far no situation has ever warranted use of the last final escalation level.

A final thought – ” Greece is collapsing, the Iranians are getting aggressive, and Rome is in disarray. Welcome back to 430 BC”.

Ask Ariely: On Fun Money, Santa, and Feeling Old

Jun 20

Here’s my Q&A column from the WSJ this week  and if you have any questions for me, you can tweet them to @danariely with the hashtag #askariely, post a comment on my Ask Ariely Facebook page, or email them to


Dear Dan,

My parents, both over 60, have retired from careers in government service, with good retirement funds plus a decent monthly pension. When they were young, they faced a lot of financial difficulties, so over the years, they have turned into misers. They don’t go on holidays, dine out or indulge in any way; they buy substandard groceries, take public transportation to save on gas and fret over even petty expenses. I want them to enjoy the rest of their lives without such worries. What should I do to change their behavior regarding money.


Your parents’ problem comes bundled with substantial benefits. Saving early in life and living modestly are key to a healthy retirement, and I wish that more people in the U.S. behaved this way. You probably owe much of your own financial well-being and your mind-set toward money to this exemplary behavior.

That said, now that your parents are comfortable, it would be good if they were able to enjoy life to a higher degree. If I were you, I would sit with them and go over their monthly balance sheet to try to figure out how much money is coming in every month and how much they are spending on necessities.

With these numbers in hand, I would look at how much extra income they have every month—and call these funds “fun money.” Next, I would get them two prepaid debit cards and set up an automatic monthly transfer of the fun money from their checking account to the cards. In this way, the fun money will be set aside from the beginning, with a different physical identity and declared purpose—a little like chips in a casino. If you want to further drive the point home, put large red stickers on the cards and write “Fun” on them.

Finally, for the first few months, you could go over the statements with them to make sure that they are indeed spending the money in ways that make them happy.


Dear Dan,

Do you think it’s acceptable for parents (and society in general) to lie to young children about the existence of Santa? I don’t, but I seem to be in the minority.


My research center recently completed a documentary on dishonesty in which we interviewed individuals who had committed misdeeds, from insider trading to doping to infidelity. Many people, we found, take one wrong step, then rationalize it, then take another—and soon they’re on a slippery slope.

All of which is to say: It is wrong to lie to kids about Santa. You might start with a fib about Santa, but next it could be the Tooth Fairy, and after that, maybe it’s Superman, the Avengers and who knows what else.

More seriously: Your children will find out at some point, and when they do, it could cause a loss of trust that could be very unhealthy.


Dear Dan,

When I was a teenager and my parents were in their 40s, they seemed old to me. Now I am almost 40, and I still feel young. Is it true that we stay young for longer these days? In the 21st century, when do people start feeling old?


Despite our amazing advances, we don’t stay young for longer. The difference is your perspective. We look at ourselves as the standard, paying less attention to differences that we consider positive and overemphasizing ones we see as negative. As for your question about when we start feeling old, that’s simple: We start feeling old when we look forward more to a good night’s sleep than to a night of passion.

Ask Ariely: On Funny Decisions, Security Insecurity, and Anthrax Horn

Jun 06

To celebrate today’s Ask Ariely column, I’d like to share the final Reader Response video. (But don’t worry, you can always check out the rest of the collection in this album.)

Here’s my Q&A column from the WSJ this week  and if you have any questions for me, you can tweet them to @danariely with the hashtag #askariely, post a comment on my Ask Ariely Facebook page, or email them to


Dear Dan,

Is there any research on the relationship between humor and the quality of decision-making? Does humor make for better or worse decisions?


Both. On the positive side, it has been shown that humor can improve creativity, which broadens the perspective from which we examine a problem and helps us to come up with novel solutions. In one study, researchers gave subjects a box of tacks, a set of matches and a candle. Their assigned task was to affix the candle to the wall so that it wouldn’t drip on the carpet when lighted. Subjects who had watched an amusing video clip before the task were more likely to recognize the solution: tack the box (which held the tacks) to the wall and use it as the candle’s base.

On the negative side, humor gets us to believe that things are safe, which can lead to risk-taking behavior. For example, recent research in the lab of Peter McGraw at the University of Colorado, Boulder, shows that humorous public service announcements are less effective than their traditional, nonhumorous scary counterparts. Why? Because the joking tone puts people at ease.

So as far we can tell, the effect of humor on the quality of decision-making is mixed. But using humor in an interpersonal relationship is certainly a good thing. It enhances liking and trust—and Prof. McGraw’s findings also suggest that humorous people are more attractive as lovers.


Dear Dan,

My wife and I bought a new house and are fighting about the door locks. She wants to replace all of the locks, fearing that some people might have keys that would let them enter. I think that there are many ways a thief could break into the house without bothering with a single door, so why spend money to deal with that negligible part of the problem? It seems to me that her irrational insecurity blinds her from the truth. Any advice?


Your wife’s fear has to do with the ease and vividness of imagining a bad outcome rather than the probability of something actually happening. After the attacks of 9/11, for example, we were all more afraid of flying, so some people switched to driving. As a consequence, over the following months, more people died from car accidents. The increase in the number of people dying from car accidents was much higher than the number of people dying on flights.

This aspect of emotions is also why we are more afraid of Ebola (which, thankfully, did not kill many people in the U.S.) than of the seasonal flu (which kills thousands of people every year). Given that the power of emotions is connected to their vividness, it is only partially useful to try to counteract them by providing accurate information about probability. Sometimes it is better just to try to deal with our emotions more directly.

Your wife’s fear may not be rational, but neither is your refusal to take such a small action to make her less worried. Why not use this as an opportunity to look at all the new locking technologies out there (some of them are really interesting). You could turn replacing the locks into a fun activity for yourself.


Dear Dan,

Is there a way to use behavioral economics to stop rhino poaching? Some people believe that consuming rhino horn cures a range of ailments, and though this is entirely mythological, it is hard to get them to change their minds about its supposed health benefits. Can you think of a way to undermine this market?


Sadly, it is very difficult to use information or experience to counteract such mythical beliefs. The only way to fight them is with other beliefs. One approach would be take advantage of the widespread myth about the link between rhino horn and anthrax, and work hard to propagate this false belief. People might still believe in the healing power of rhino horn, but their fear of anthrax might overpower it.
