Dear Dan,
Delta Air Lines recently announced plans to start distributing thousands of Microsoft Surface 2 tablets to its pilots to spare them lugging around heavy documents, maps and flight plans. As a passenger, I always suspected that flight attendants sometimes ask us to turn our gadgets off not because they might harm the plane’s instruments but because some airline employees get a kind of twisted satisfaction from making passengers suffer a bit more. What do you think? Is the whole issue of turning electronics off just a way to make the passengers realize that the flight attendants are really in control?
—Adam
In fairness, the unpopular (and rapidly fading) ban on using personal electronics during takeoff and landing was a Federal Aviation Administration regulation, not a policy by the airlines. Even so, the logic of turning off iPads and Kindles while taxiing was never clear to me either, and the joy that some flight attendants took in commanding passengers to turn their devices off could make one suspect that your “control theory” is right. Nevertheless, I suspect that this was just one more regulation set up without much thought that the poor flight attendants were forced to follow—and that in fact, they most likely suffered much more from having to enforce a rule that annoyed passengers and lacked logic many times a day.
I do worry about another aspect of your question: making airplanes too reliant on tablet technology. A crash of the less dangerous type could translate into a more harmful one.

Dear Dan,
I recently had a massage when I was very tired, and I fell asleep repeatedly. Every time I dozed off, the masseuse moved me particularly vigorously and woke me up. This left me a bit embarrassed, and it wasn’t fun to be woken up so many times in one hour. What should the masseuse have done—let me sleep through the massage, or woken me up to experience it?
—Merve
The person giving you the massage was wrong. More generally, this is really a question about different types of pleasure and their building blocks. In general, you can think about the pleasures you get from anticipating a massage, experiencing it, and remembering it after the fact.
The interesting thing about remembered and anticipated pleasure is that they capture some aspects of the experience—but not all of them. That’s why, for example, you might remember an experience that was great for 15 minutes as better than an experience that was great for the first 15 minutes and then merely good for 15 more. In essence, the longer experience had more goodness in it (30 minutes), but the remembered pleasure wasn’t as large because it also involved some less exciting moments.
I suspect that the masseuse wanted you to have more moments in which you experienced the massage—but by doing so added some less pleasurable parts and decreased your remembered pleasure, which will also decrease the anticipatory pleasure you’re likely to feel before your next session on the table.
This lesson, by the way, applies to many other domains of life. Think about a presentation to clients, a dinner party, or a discussion with a friend—it’s the quality, not the quantity, which influences our remembered and anticipated pleasures.

Dear Dan,
My kids are spending much of their time on social networks such as Facebook. Are they really being social with their friends or just wasting time?
—Dafna
Here’s my test for real friendship: Would your friends bail you out of jail if you needed them to? My sense is that spending face-to-face time with friends is likely to increase the likelihood of bail, while following someone’s status updates won’t. If your kids aren’t increasing their odds of getting real help when they need it, they probably aren’t being social in a meaningful way.

With the holiday season upon us, it’s a good time to reflect on the things we have that we truly need and the rest that is just superfluous. How greedy are you?
In line with this thought, our very own Dan Ariely and Aline Grüneisen published an article in the November/December Scientific American Mind on the price of greed.
For a juicy excerpt, read on:
Ferocious competition may occasionally lead to optimal market outcomes, but it can also have harmful side effects. Think about competition in sports. At first glance, the drive to be the best appears to propel human achievements to new heights. World records are surpassed, and yesterday’s Olympic medalists pale in comparison with today’s champions. Yet extreme dedication has costs. Athletes may not spend enough time with their friends and families, or they may sacrifice their long-term health to perform better in the short term — by overexerting their body or taking performance-enhancing drugs such as steroids.
The consequences of unchecked greed can also spill over into society. In his 2011 book The Darwin Economy, economist Robert H. Frank of Cornell University outlines some of the disastrous effects of allowing competition to run free. Take, for example, neighbors gunning for social status. Each tries to outdo the others, purchasing a slightly flashier car, bigger pool or more expensive grill. When Joe Jones down the block builds a home theater and Jane Smith across the street installs a 3-D amphitheater, you will no longer be satisfied with your meager widescreen television. We don’t simply try to keep up with the Joneses, we try to surpass them…

Let me set the scene: It’s midway through the annual Society for Judgment and Decision Making conference in Toronto. Inside a conference room, behavioral and health scientists passionately discuss how to help people make healthier decisions while the event staff set up a snack table with coffee and huge cookies outside.
The session ends and the scientists start to exit, and I wonder what will happen next—will these scientists who are so interested in promoting health eat the cookies?
The answer is a resounding “Yes!” Every cookie is gone within minutes (even the raisin ones).
How should we make sense of these scientists’ apparent hypocrisy? It may be hard to imagine, but scientists can have difficulty following their own goals, just like everyone else. Behavioral scientists don’t just study irrationality, but live with it, too. Despite our own efforts to live rational lives, we find ourselves choosing irrationally and failing like everyone else—and this can become a large inspiration for our research.
As researchers, we understand that we have troubles with email addiction, procrastination, and blind optimism. We look at our own lives and say, “What could have helped me be more rational or what could have helped me exert more self-control?” At others times we ask ourselves, “What could have helped me relax more?”
Behavioral scientists should arguably be the most motivated to make healthy and rational choices, because we know the consequences of our actions all too well and are aware of the mistakes we make in pursuing our goals. Yet, we still do things like reach for the cookies we know we shouldn’t eat and constantly check our email, even though we know that such cognitive switching can greatly impair our work performance.
If all this education is not enough, then we need more than just lessons. That’s why we need research to develop technologies that aid us in self-control such as choice architecture, decision aids, better public policies, and general environmental design that enables better decisions.

At the Center for Advanced Hindsight, we make efforts to create a healthy and productive environment that can protect ourselves from ourselves. We try to keep the cupboards full of easily accessible health foods to protect us from our junk food temptations. We make public social pacts to protect us from our lazy temptations. We make the lab fun and even have the peace and simplicity of the Thinking & Dreaming room to keep us protected from our inefficient overworking temptations.
Today, there are way too many cookies outside of conference rooms. We must eliminate and reduce these cookies from our environments. Rather than act as individuals and fight with our current environments, we must work to create environments that help us be great individuals together.

Every day of the year, American shoppers act irrationally. On Black Friday, however, shoppers’ irrationality and wildness climb to dangerously high levels. Why does Black Friday lead shoppers to grab and fight, especially when the stakes are often as low as fifty percent off toasters?
Over the last few decades, social scientists have cataloged the many different factors that lead to irrational consumer behavior, and Black Friday touches on nearly that entire list.
Luckily though, if shoppers stay aware of how Black Friday is designed to make them irrational—and if they take breaks, eat snacks, plan ahead, and keep a clear mind—then they can avoid falling victim to the “holiday.”
Here are seven reasons shoppers become so irrational and committed to deals on Black Friday, as well as a few ways you can protect yourself.
#1
Black Friday is like a hazing ritual
Black Friday shoppers are dedicated—they sacrifice sleep, football games, and significant others’ approval to make the early bird sales.
When people go through pain and effort to reach a goal, then the goal actually looks more attractive in an attempt to justify the unpleasant struggle. Effects like this are common—think of brutal college hazing rituals, where new members commit more intensely to the group rather than turn away.
A shopper’s first sleepless Black Friday is like a hazing ritual that makes the deals seem that much more attractive—they must be worth it after all that effort.
#2
Shoppers are too “depleted” to be rational

People are vulnerable to irrational tendencies all the time, but they are at their most vulnerable when they’re tired and overwhelmed. Behavioral scientists call this state “depletion.”
In a state of depletion, people just don’t have enough willpower to resist temptation or the cognitive faculties to make complex decisions. Even math whizzes and businesses majors will falter when depleted.
Black Friday shoppers arrive sleep-deprived and stressed from the holidays. For companies, Black Friday can seem like taking candy from a baby. Only here the baby resists even less.
#3
What’s another $10 after the first $500?
It hurts to spend money. There’s pain in parting with $10 for a flash stick. However, after spending $899 on a TV, the pain one feels parting with a Hamilton for a flash stick is practically gone.
Restraint on Black Friday is even more unlikely because many shoppers tend to begin with the purchase of a large ticket item, like a TV or computer. After the big purchase, every $10 flash stick, $11 dollar t-shirt, or $13 kitchen knife, will not lead to the “pain of paying” that keeps people from buying every random thing on aisle during the other 364 days of the year.
Nobel Prize winners Daniel Kahneman and Amos Tversky explain that people are initially “loss averse”: initially people really do not like losing money. However, once people start losing money, their aversion to losing money starts to go away. Accordingly, cautious spenders can quickly become big spenders.
#4
The shopping momentum phenomenon
Ever thought your friends turn into entirely different people when they go shopping? Well, scientific research suggests that indeed shopping does change people.
Yale consumer researcher Ravi Dhar and colleagues find we are in a careful “deliberative” mind-set before purchasing an item—carefully weighing the pros and cons. Yet after the first purchase, a floodgate of “shopping momentum” opens up, and we make purchases more readily after.
Fortunately, the phenomenon of “shopping momentum” can be interrupted by a break in shopping. However, on frantic Black Friday breaks rarely occur, so shopping momentum is likely to persist for hours, if not the entire day.
#5
The Halo Effect — Amazing By Association
One problem for shopper rationality is that the amazing door buster deals on Black Friday may create a “Halo Effect” such that even the bad deals seem amazing by association.
Black Friday shoppers are better off thinking of Black Friday as a day that has both good and some bad deals. Not every sale is a bargain.
#6
Black Friday requires math skills many consumers don’t have
To distinguish the good from the bad deals, it takes a little bit of math. But research shows many adult Americans lack the basic math skills necessary to evaluate the merits of a deal. For instance, many Americans don’t know that 10 percent of 1,000 is 100 or that 1/4 is larger than 3/20.
Many Americans have what is known as “low numeracy” which means missing questions that national standards say elementary children should know. Are shoppers smarter than a 5th grader? Most often, the answer is no.
If shoppers don’t have the math skills, they are likely to get swept up in Black Friday. Shoppers without strong math skills should feel encouraged to bring along a friend who does, or even utilize smart phone applications that allow for better product evaluation.
#7
There’s no guilt when everybody’s doing it
Businesses want Black Friday to be crowded. Not just because they want lots of wallets, but because crowds change people. In the case of Black Friday, crowds can remove all sense of guilt.
Few shoppers feel guilty buying another half-off toaster when the customers next to them have flat screens in their carts. When everybody’s peers are doing it and some peers are “doing it worse,” the painful experience of parting with money becomes a joyous spending spree.
Indeed, research on “social influence” finds that the examples of others can drive people to irrational and even unethical behavior.
Final Reminders
Don’t get too tired. Use a calculator. Decide what you want ahead of time. And don’t get brainwashed. Yes, Black Friday is fun. Yes, Black Friday is a day of great deals. But Black Friday is also a trap that’s very easy to fall into. Happy and responsible shopping everyone!
~Troy Campbell~
At our lab, we’re interested in what kinds of tools people can use to make better decisions and reach their goals. When we decided to take part in this year’s Color Run, we tried to use some of these tools on ourselves to help us get in shape and ready for the race.
Like many people, we want to exercise more and get in better shape. Everyday temptation often gets in the way, though. To fight these temptations, we turned to one of the most prevalent behavioral tools: the “commitment contract.”
A commitment contract is an agreement your current self makes with your future self—you decide how you’re going to behave before temptations cloud your judgment.
In our lab, we had everyone agree to do some type of training three times a week in the six weeks leading up to the race. In the spirit of what we know about motivation, the focus was on concrete actions (spend a certain amount of time training) rather than vague outcomes (run a fast race).

“Some type of training” is pretty open-ended, so we each defined on our contracts what actually counted as a training session for us—this way we could all train to our own level while maintaining concrete goals. This is important because we all vary in how fit we currently are and how fit we ideally want to be. Research shows personal goals can be more success that striving after a single public standard. The standard becomes too high or too low for many people and leads to demotivation.
Commitment contracts are effective, but we decided to take the commitment up another notch by including social incentives. We each kept track of our training goals on a chart we posted in a very visible high traffic area – right by the kitchen!

The chart helped us track progress from person to person and week to week. The chart made our commitment (or lack of commitment) very visible to each other and ourselves. It’s painful enough to fail privately, but it’s even worse when everyone else can see us coming short of our own standards.
So, how did it work?
For the most part it worked fantastically. However, you can see that a handful of people fell off the bandwagon and never got back on. This is what behavioral economists playfully call that the “what-the-hell” effect.
Importantly though, about one-third of the team succeeded in completing all training sessions, and others were motivated to exercise more or harder than they did before.
It’s important to note that on average, exercise in the lab shot up and as a whole we moved toward our goal. Perfection with any intervention is not expected, but, as a group, we definitely made strides forward.
To better understand what was going on, I talked with some of our lab members to get their assessment.
For some of us, this was an all or nothing endeavor:
“Just knowing that I needed three stickers each week and would be anything less than perfect if I didn’t get all three got me to put on my running shoes without fail.”
Some people used the contracts and the process of defining what “counted” as a training session to eliminate the possibility they would take too much wiggle room:
“For me I always work out but sometimes I don’t feel so good and I ‘call it early’ and stop before getting a full workout. With the pre-commitment this didn’t happen. The fixed time goal kept me from quitting early.”
Other people used the contracts to build in wiggle room, just in case.
“I made my commitment contract loose enough that I could justify yoga or sex as exercise activities, but I never took advantage of the ample wiggle room.”

In the end, the training probably didn’t radically transform anyone from couch potato to athlete or yield dramatic before and after photos (nor did it exactly have randomized and controlled trials), but it seems safe to say that everyone got a little extra boost—even those who didn’t train. As one visitor to the lab remarked “You can’t look at all those smiley faces and not smile back.”

Dear Dan,
I waste about two hours each day playing stupid games on my iPhone. It feels so innocent, but it actually makes me lose focus at work and takes up time I should be spending with my wife and kids. Do you have an idea for how I can ditch this bad habit?
—Arianna
One way to fight bad habits is to create rules. When you start a diet, for example, you can set yourself a rule such as “I won’t drink sugary beverages.” But to be effective, rules need to be clear and well defined. For example, a rule such as “I will drink only one glass of wine a day” is unlikely to work. With this type of rule, it is not clear what size of glass we are talking about, or if we can drink more today and reduce our drinking next week. In essence, if the rule is not clear-cut and unequivocal, we are likely to break it while deceiving ourselves that we are actually following it.
In your case, you could decide that, from now, on you won’t be playing the iPhone between 6 a.m. and 9 p.m. And to help you follow this rule, you should let your loved ones know. Or you could set up game bans for weekdays or working hours. Good luck.

Dear Dan,
I am in middle school, and there is one topic in school I really love and one I really dislike. There is also one teacher I really love and one teacher I am not very excited with. Would I be better off if the teacher I love taught the topic I love, and the duller teacher taught the topic I dislike? Or would I be better off if the teacher I love taught the topic I dislike, and the duller teacher taught the topic I love?
—Tima
What you are really asking me about is the accumulation of pleasure and pain. On the one hand, you might argue that having one class with a great teacher and a great topic, and one class with nothing going for it, would give you at least one class to look forward to. You might also argue that, if a class isn’t going to be good, it doesn’t really matter how bad it is—adding a good teacher to a bad topic, for example, wouldn’t help much.
On the other hand, you might argue that a class with a bad teacher and a bad topic is going to be too much to bear. In this case, the combined pain might pass your tolerance threshold and color the entire semester.
I should say, first, that I am delighted you like some of your teachers and topics, and I don’t want you to stop thinking of school as joyful. But I do think that the mixing approach would be better for you.
I suspect that having a class with a bad teacher and a bad topic will be too much for you to handle. And I suspect that in the class with the teacher you love and the topic you don’t, you will learn to focus on the teacher and pay less attention to the topic, while in the class with the teacher you dislike and the topic you love, you will learn to focus on the material and pay less attention to the teacher.
I wish you many years of joyful (or at least not torturous) learning.

Dear Dan,
What do you think is the best psychological approach to getting over a girlfriend? Should you cut off seeing her completely? Continue getting together for coffee, etc.?
—Jason
I suggest that you cut it off completely. Meeting an old girlfriend over and over, while wondering if you should have ended things or not, is just going to prolong the pain—and without any real value.
See the original article in the Wall Street Journal here.
During my recent trip to New York City, I spent quite a bit of time sitting in taxis—taxis with ads that endlessly drill messages into your thoughts. I’ve never watched much TV, so my brain hasn’t evolved that uniquely American ability to tune out the mind-numbing commercials. As hard as I try, I just can’t look away when there’s a TV in sight.
As the commercials looped, one ad stood out to me and had me grinding my teeth each time it popped onto the screen. It wasn’t that it looked like an old-fashioned PSA, or because its protagonist donned a charmingly insincere Mr. Rogers smile. No—this ad grabbed me because of its heartbreaking ignorance of basic psychology. The goal of this ad was to get passengers to buckle up for safety, but its method was painfully misguided.
A number of strategies have been used over the years to get people to buckle their belts. For example, we have:
• Laws. This map shows the seatbelt laws in all US states, and according to the National Safety Council, seatbelt use is 13% higher in states with primary enforcement (meaning you can get stopped and ticketed just for not wearing a seatbelt) than those with secondary enforcement (88% versus 75%).
• Penalties. Although people are probably not thinking about the $69 fine they might have to pay or even the drivers license points they could rack up if they get caught, it is possible that some people may buckle up to avoid these consequences.
• Enforcement. Here, we’re talking about high-visibility enforcement such as checkpoints where all cars are stopped to check for seatbelt usage.
• Incentive awards for police officers to give tickets (ranging from small model cars awarded to individual police officers to much larger grants for police agencies).
• “Click it or Ticket.” This campaign has been particularly effective because it serves as a reminder of the immediate stakes (getting a ticket), even though they are smaller than the larger consequences (such as sustaining an injury in an accident). Reward substitution works. Fun fact: the campaign began in North Carolina, home of the Center for Advanced Hindsight, and was adopted by other states because of its success (most likely due to its catchy name).
• Safety belt reminder systems. These excruciatingly loud alarms get my passengers to buckle up in record time.
• Safety belt ignition interlocks. Some cars will refuse to start until all belts are in, although you can imagine why the idea hasn’t gained much traction.
• Education. Teaching children about seatbelt safety in school, while not an official persuasion method that I can find in any academic paper, has turned diligent recycling enthusiasts who just say no to drugs into relentless seatbelt reminder machines. I imagine that if our kids were the enforcers of just about anything, we would all be better off.
Some of these strategies work better than others, but none of them are actually detrimental to seatbelt compliance. And yet this taxicab ad, which I was forced to watch over and over in agony, conspicuously ignored what we know to be a primary motivator of behavior: social validation.
The ad gave one pivotal piece of information, which you can see in the accompanying photo: “60% of taxi passengers do not buckle up.” This kind of scare tactic is ineffective because it simply sends the wrong message.

Robert Cialdini has shown over and over again that social proof is an intoxicating principle of persuasion. We look to others to decide what to do, and when we are told about how most people behave in a given situation, we are likely to follow their lead. (This is why “word of mouth” can be so powerful, and companies pay top dollar to try and influence what their customers tell their friends.)
So, what message does this ad convey to cab riders?
This statement gives an implicit recommendation, noting that most people do not wear seatbelts. As social creatures, we look to others to determine how to behave in all kinds of situations, and riding in a taxi is no different. Rather than encouraging seatbelt use, this statement lets seatbelt-wearers know that they are in the minority while giving non-seatbelt wearers the comfort of knowing that their behavior is normal. It doesn’t matter why the majority doesn’t wear seat belts—whether it is uncool, unsanitary, too much of a hassle, or even unsafe—now they know that most people don’t do it, and that’s a good enough reason to go along with the flow.
If you want to persuade people to wear seatbelts, you should tell them that 84% of people in the US do wear seatbelts. Or you can further tap into group identity by noting that 90% of New Yorkers wear seatbelts.
It’s a shame that a message as important as “wear a seatbelt” could be so badly butchered. If companies have figured out how to use the concept of social proof to get people to spend more money, why can’t our safety promoters figure out how to use it to get us to make better decisions?
For a quick review of all six of Cialdini’s principles of persuasion (reciprocation, consistency, social validation, liking, authority and scarcity), see this article.

Dear Dan,
I am the president of a local union that represents many federal workers. We are dealing with an interesting complaint stemming from the days during the government shutdown when employees were furloughed. Staffers who were furloughed are getting back pay for the days they were off, and because of this the employees who were designated as exempted from the furloughs (who originally felt special about their status and contribution) now feel gypped: Some of them expressed feeling like “a fool for working while others got to stay home.” Any advice?
—Robert
The current approach is clearly the wrong way to design paybacks after a furlough. Since we are likely to experience more government shutdowns in the years to come, maybe we should have a strategy for handling such situations.
I would suggest creating small groups composed of both furloughed and exempt employees and letting each furloughed worker decide how much of their back pay he or she is willing to contribute to the exempt workers in that group. A lot of research shows that people care to some degree about the welfare of others and about fairness, and we do so even at a cost to our own pocket. This kind of social utility should get the furloughed employees to act fairly, and they are even likely to be extra fair if the amount that they would give is going to be posted publicly and contribute to their reputation.
It’s possible that the government at some point will step in and do something to correct the issue. But while this local approach won’t completely fix the problem, it should make the distribution of income more equitable and, just as important, increase camaraderie among employees.

Dear Dan,
I love drinking good wine. Each time I go to a restaurant I wonder what is the ideal amount of money to spend on a bottle. What do you do?
—John
A recent experiment suggests an answer. Ayelet and Uri Gneezy from the University of California, San Diego, teamed up with a winery owner in their state to figure out, experimentally, the best price for his Cabernet. On some days they sold the wine for $10, on others for $20 or $40. Demand fell off at $40, but the winery sold more bottles of its Cabernet when the price was $20 than $10. On top of that, the customers who paid more indicated that the wine tasted better!
Uri and John List describe that experiment in their new book “The Why Axis,” in which they use field experiments as a method to look at many of life’s questions, from wine to love to the workplace. Their main advice is that we should all do more experiments.
So, the next time that you go to a restaurant, order two glasses of the same varietal of wine, one rather basic and one fancy, and tell the waiter to write down which is which and not to tell you. Then see if you can tell the difference. Of course, trying this experiment with just two wines is bad science, because you could be correct by chance, so you need to repeat the experiment many times. My guess? Your ability to tell the price difference will be indistinguishable from random guesses.

Dear Dan,
I recently watched your presentation at a professional conference and was wondering why an Israeli guy telling Jewish jokes is wearing an Indian shirt?
—Janet
In general I am not someone who should be asked for fashion tips, but this might be an exception. I like to dress comfortably, but in many professional meetings there is a code of uncomfortable dress: suits. My solution? I figured that as long as I am wearing clothes from a different culture, no one who is politically correct would complain that I’m underdressed. After all, the critics could be offending a whole subcontinent. Now that I think about it, maybe I should start giving fashion tips.
See the original article in the Wall Street Journal here.
