Dear Dan,

I was recently stuck overnight in a strange city due to a canceled flight. Because the airline blamed the cancellation on “weather,” no one helped me find a place to stay or pay for it. Meanwhile, I saw other flights leaving the same airport. Is “weather” just a term airlines use when they try to consolidate flights, not compensate their customers and avoid blame?

—Kelly

I am sure that sometimes the weather really is at fault, but I have no idea whether the airlines use the weather excuse promiscuously when it’s to their financial advantage. It would be difficult to make such a judgment call (should we call the reason for the delay the weather or technical issues?) while completely ignoring the economic incentives involved. And blaming all kinds of things on the weather is a very useful strategy for the airlines because trapped fliers don’t directly blame the airlines for it.

But let’s be honest here: Many of us also sometimes blame our own tardiness on traffic or the weather. And I suspect many of us would blame the weather even more frequently for all sorts of lapses if we just had the opportunity.

To my mind, the weather excuse (as the airlines use it) has one major problem. The airlines’ logic is that bad weather is an act of God, which releases the airline from responsibility. But isn’t the airlines’ behavior probably the reason God is angry to begin with?

Dear Dan,

How can I enjoy life more? Every year, time seems to go by faster; months rush by, and years just seem to disappear. Is there a reason for this, or is the memory of time passing more slowly when we were children just an illusion?

—Gal 

Time does go by (or, more accurately, it feels as if time is going by) more quickly the older we get. In the first few years of our lives, anything we sense or do is brand-new, and a lot of our experiences are unique, so they remain firmly in our memories. But as the years go by, we encounter fewer and fewer new experiences—both because we have already accomplished a lot and because we become slaves to our daily routines. For example, try to remember what happened to you every day last week. Chances are that nothing extraordinary happened, so you will be hard-pressed to recall the specific things you did on Monday, Tuesday etc.

What can we do about this? Maybe we need some new app that will encourage us to try out new experiences, point out things we’ve never done, recommend dishes we’ve never tasted and suggest places we’ve never been. Such an app could make our lives more varied, prod us to try new things, slow down the passage of time and increase our happiness. Until such an app arrives, try to do at least one new thing every week.

Dear Dan,

My daughter recently persuaded me to start eating two cloves of garlic every day. I feel more energetic and less stressed. Is it the garlic, or is it a placebo?

—Yoram 

I am not sure, but have you considered the possibility that the reason you feel so much better is that people are now leaving you alone?

More Mulling over Squirrels

February 10, 2014 BY danariely

Last week I answered this question about squirrels:

Dear Dan,

I find myself acting irrationally when it comes to squirrels. The rascals climb down a branch and onto my bird feeder, where they hang and eat like limber little pigs. Then I rush outside yelling and take great pleasure in frightening them away. But victory never lasts long. They come right back, and the whole insane cycle starts over. My sister tells me I need to watch “Snow White” again, to be reminded that squirrels are also a part of nature and not inherently worse than the birds I prefer. Perhaps, but this theory doesn’t satisfy me. Can you help to explain what’s going on with my reasoning, and how I might make peace with the furry marauders in my yard?

—Nearly Elmer Fudd

It sounds to me that the root of your problem is that you view the squirrels’ behavior as an immoral theft from the right owners of this food, the birds. If so, why don’t you start calling the contraption a “squirrel and bird feeder”? With this new framing, your problems should go away, and you might even be able to market this new product.

I did not anticipate this, but I got more email in response to this topic than any other answer I have given over the years. Who knew? This was news to me, but maybe someone should start a support group to help people deal with these topics. And what did people write? Some emails were expressing strong anti-squirrel emotions, some were giving me more facts about the damage that squirrels create. One email even provided me with an analysis of the cost to the electrical grid as a consequence of squirrels eating away at the power lines. And of course I got lots of pictures describing the many ways people are trying to protect their birdfeeders (below is my favorite example):

Dear Dan,

Do you think that colleges should continue teaching subjects like philosophy, sociology and literature? After all, they’re a waste of time and money.

—Clara

With something like computer science or statistics, we find it easy to assess what skills we will acquire and how we will use them in a practical way. But with sociology, literature or even psychology, it is not always exactly clear how our studies are going to change us. Are we going to learn how to think analytically or see things differently? And how valuable are these skills anyway?

Maybe it is worthwhile to think about education as a lottery ticket. After all, like a lottery, when it comes to academic education we don’t know exactly what we’re going to get, and we’re not 100% certain that our degree will always justify our investment. But what if for every year of studying you got one really good idea? Or if your education somehow improved your mental capacity by 10%? Think of your education as a lottery ticket that you get to use year after year for the rest of your life. Of course, it is hard to predict what exact benefits you’ll reap from good ideas or an improved mental ability, but if you think about education as a long-term bet, I suspect that you will easily see it as a bet with very high expected payoffs.

P.S. In the interest of full disclosure, I should point out that as someone who teaches for a living, I have a vested interest in students continuing to attend universities. And maybe, in this case, it is hard for me to see the world from a different perspective.

Dear Dan,

I was talking with a friend about your research on dishonesty, notably the way that people feel free to steal sodas and cookies from the “break room” but not cash. My friend said that office items such as staplers, tape dispensers and so on used to be constantly taken from his desk. He then glued a quarter onto each piece, and no one has taken anything with a coin on it for five years. Does this follow your findings?

—Tony

I love the application of this finding. Now, if we could only glue quarters to stock certificates and other financial products, maybe the world would be a better place.

Ask Ariely: On Airborne Electronics, a Mistaken Masseuse, and Friends who Post Bail

______________________________________________________

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.

The Price of Greed

December 6, 2013 BY danariely

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…

Are dogs really people?

October 7, 2013 BY danariely

A few friends, well aware of how completely obsessed I am with all things dog-related, have been sending me this recent New York Times op-ed about whether or not dogs are people. The answer that Emory neuroeconomist, Gregory Berns, gives is “yes.” At least the kind of limited personhood we might grant to small children. I was hoping to love this piece but instead felt frustrated that the findings seem to rely more on—to borrow a phrase—the seductive appeal of neuroscience, rather than any empirical basis.

Berns begins by noting limitations in understanding animal emotion, disparaging the “behaviorism” in animal research. He tries to get around these restraints by putting dogs in an fMRI machine. After some trial and error (that’s adorable to visualize), Berns explored activation in the caudate nucleus—a brain region associated with reward, memory, and learning—focusing specifically on the caudate’s role in anticipating things that we enjoy, as well as its functional and structural similarity across dogs and humans. He writes in the critical two paragraphs:

In dogs, we found that activity in the caudate increased in response to hand signals indicating food. The caudate also activated to the smells of familiar humans. And in preliminary tests, it activated to the return of an owner who had momentarily stepped out of view. Do these findings prove that dogs love us? Not quite. But many of the same things that activate the human caudate, which are associated with positive emotions, also activate the dog caudate. Neuroscientists call this a functional homology, and it may be an indication of canine emotions.

The ability to experience positive emotions, like love and attachment, would mean that dogs have a level of sentience comparable to that of a human child. And this ability suggests a rethinking of how we treat dogs.

First, it seems an empirical and philosophical stretch to consider “experiences positive emotions” as a coherent and plausible criterion for personhood. I’m also unconvinced that caudate activity is solid enough ground to infer sentience, since rats have a functioning caudate that responds to rewards.

Second, it’s not at all clear to me why neuroscience is required to make this conclusion. If we want to give personhood to animals that experience positive emotions, then why go through the trouble and expense of putting dogs in an fMRI machine? It’s pretty obvious to me when my dog is happy. He perks up, he wags his tail, he grins, he looks at me lovingly when I scratch his ears, he sighs contentedly when he chews on bones and other things, and so on. I don’t need to examine activation in his caudate to realize that he’s experiencing positive emotions.

It could be argued that we can’t actually observe the positive experiences in dogs—we can only make inferences from behavioral similarities. And in that case we’d want to look deeper into the subjective experience that dogs might have. Neuroscience is a tempting alternative, but it’s a shallow one—it only feels more scientific without providing much payoff.

What fMRI scans tell us is that certain regions of the brain receive more blood at certain times during a task. So if we see more blood flow to the caudate when dogs look at their owners or see a hand signal associated with food, we infer that the caudate is more active. But how is caudate activation enough to infer something about what dogs experience?

We still haven’t observed any emotion, but rather brain activation. You could appeal to structural or functional homology, as Bern’s does (i.e. “dogs and humans both have caudates that respond to similar things, so they must feel similarly, too”), but notice we’re no better off than where we started. We’ve simply replaced one assumption with another. If the first (“dogs and people both smile, so dogs feel like people do when they smile”) is unjustifiable, so must be the neural one. We’ve learned nothing new about what dogs experience, but rather that dogs show activity in reward regions when they see things they enjoy (which, like, duh?). We’ve only bought the sexy feeling that the science we’ve done is somehow more legitimate.

Which leads me to my last pet peeve (hah) about the OpEd—the constant suggestion that neuroscience has triumphed over the constraints of behaviorism, while ignoring that psychology has been looking beyond behavior just fine for a long time. Animal psychology has been no exception, here. I know of and have been involved in a lot of comparative cognition research with animals (the operative word being “cognition,” not “behavior”). I have good friends who work with Brian Hare at Duke, the co-director of the Canine Cognition Center at Duke and author of The Genius of Dogs, and my undergraduate advisor is currently diving into dog cognition, herself. There is a lot of great research that explores how canines think, not just behave. All without the aid of fMRI’s.

fMRI is a great tool, no doubt. But it’s not the only way to learn about the mind, and it certainly has it’s limits. These limits do not go away, however, when looking at other animals. So even though I love my dog (a lot), he’s probably not a person (though I might treat him like one, sometimes). If he is, though, it’s going to take more evidence than this study to convince me.

Ask Ariely: On Wasted Time, Framing Failure, and Matrimonial Gambling

September 28, 2013 BY danariely

______________________________________________________

Dear Dan,

Often when I meet with a group of my closest friends, the discussion goes something like this: “Where do you want to go?” “Not sure.” “Where do you want to go?” “Not sure.” Etc. These discussions are frustrating and waste time. Any advice on how to move them forward and get to a decision faster?

—Matthew 

When someone asks “What do you want to do tonight?” what they often are saying implicitly is: “What is the most exciting thing we can do tonight, given all the options and all the people involved?”

The problem is that figuring out the best solution is very difficult. First, we need to bring to mind all the alternatives, next our preferences and the preferences of the people in the group. Then we have to find the one activity that will maximize this set of constraints and preferences.

The basic problem here is that, in your search for the optimal activity, you are not taking the cost of time into account, so you waste your precious time asking “What do you want to do?”—which is probably the worst way to spend your time.

To overcome this problem, I would set up a rule that limits the amount of time that you are allowed to spend searching for a solution, and I would set up a default in case you fail to come up with a better option. For example, take a common good activity (going to drink at X, playing basketball at Y) and announce to your friends that, unless someone else comes up with a better alternative, in 10 minutes you are all heading out to X (or Y).

I would also set up a timer on your phone to make it clear that you mean business and to make sure that the time limit is kept. Once the buzzer sounds, just start heading out to X (or Y), asking who wants to come with you and telling everyone else that you will meet them there. After doing this a few times, your friends will get used to it and perhaps bring an end to this wasteful habit.

______________________________________________________

Dear Dan,

I’d like to understand something I see in my own life and in billion-dollar companies: the switch from aiming to succeed to aiming not to fail. You see this in companies such as Microsoft, but even the National Aeronautics and Space Administration went from the ambitious 1960s-’80s era to its current conservative program. What can we do to overcome this problem?

—Alex

Assuming this is indeed a generalized pattern (and it would be interesting to collect data on the question), it might be a simple outcome of the endowment effect: basically, once we own something, we get used to it and are very reluctant to see it go away. When you are just starting out, you have nothing, so you look at potential gains and losses to some degree on an equal footing. But once you experience some success, you start thinking more carefully about what you have, and you don’t want to give it up, so you become much more conservative. In the process, you give up the things that made you successful from the get-go. Nor are companies alone in this: I suspect that the tendency to switch to a do-nothing defensive posture is just as common in the behavior of our public officials and governments.

______________________________________________________

Dear Dan,

Someone once said to me that marriage is like betting someone half of everything you own that you’d love him or her forever. Do you agree?

—Shane

From the perspective of an outside observer, there are some things in life that can be described as a bet or a gamble—while for the people directly involved, looking at it that way will be a very bad idea. Marriage is one of these cases. It might be fun and interesting to think about other peoples’ marriages in such terms, but don’t be tempted to think about your own relationship this way. And certainly don’t mention these odds to your significant other.

Ask Ariely: On Audiobooks, Idle Waiting, and Public Transportation

August 31, 2013 BY danariely

______________________________________________________

Dear Dan,

From time to time, people around me discuss a book they have read recently. While I know the book well, and I want to participate in the conversation, I hesitate because I listened to the book on tape. My first question is why am I embarrassed to say that I listened to the book? My second question is what can I do about it?

—Paula

We learn how to listen and comprehend at a young age and therefore we don’t really remember how difficult it was for us. On the other hand, we learn how to read and write at a later age and we all remember the difficulty of the early struggles with reading and writing. Because of that, people associate greater difficulty with reading than listening. As a consequence, we take greater pride in reading than listening.

My first suggestion is that you realize that it isn’t necessarily the case that reading is more difficult. It’s just that we forget how difficult it is to learn to comprehend. When I got your question I purchased an audio book and I listened to it on a long flight–and for what it is worth, I find it is harder to focus when listening to a book than when reading one.

A second suggestion is that you to find a different word to describe your experience. For example, for books you loved, maybe you can say: “I inhaled that book.” For more difficult books, maybe you can say: “I struggled with it,” or some other phrase.

If these don’t work, perhaps it is time to change the meaning of the word “read.” Maybe we should acknowledge that today there are many ways to get information — audiobooks being one of them. This might seem dishonest, but you might be able to start a revolution, and help lots of people who listen to audiobooks feel more comfortable with what they’re doing. Good luck!

______________________________________________________

Dear Dan,

I noticed that when I drive around the block looking for parking I spend a lot of time too far away from my destination (I live in Chicago, and hate the cold), so instead, I just wait until somebody leaves and take the spot. It proved to be more efficient, but my friends can’t seem to stand it, and I can’t do it when I’m not alone in the car. My question is why my friends find in intolerable waiting for someone to leave.

—Danny 

The phenomenon you’re encountering is aversion to idleness. There was a story a while ago about an airline that tried to optimize which carousel that the luggage would come out of. There was an engineer with this airline that realized that some carousels were close to some gates, and others were close to other gates. He wrote an algorithm to try to figure out which carousels to send the luggage to so that it would be closest to where the plane was landing. Before this algorithm was created, travelers would get out of the plane, walk for a while and get to the carousel. Sometimes it was such a long walk that their luggage was waiting for them already, and they would pick it up and go home. In the new system, the carousel was much closer and people would walk a little bit, find the carousel and wait for their luggage. People hated this new system because they were standing in one place to wait for their luggage. This idleness was so unpleasant that people complained and the airline rejected this algorithm. My understanding is that they have not gone the whole way in the reverse and tried to get the luggage in the farthest carousel possible, but maybe it is something they are still working on.

______________________________________________________

Dear Dan,

Many people justify evading paying for public transportation by rationalizing that “public transportation services aren’t value for money,” that “it’s a victimless crime,” and that “as a tax paying passengers, we’ve already paid for my journey once.” Do you have any advice on counteracting these rationalizations?

—Julian

Make these people buy some shares of the public transportation company.

Murder’s Morality

August 24, 2013 BY danariely

There are plenty of things that might upset Johnny “The Basin Street Butcher” Martorano. Perhaps having murdered 20 people in the course of his career as a mob hitman doesn’t sit so well decades later. Well, no, this is not it,  Martorano recently recounted his murders as part of Whitey Bulger’s trial with a perfectly flat affect, much to the displeasure of his victims’ families. It seems guilt doesn’t keep him up at night.

Then maybe it’s the 12 years he spent in prison after confessing his crimes to the FBI? Not likely, given Martorano now lives in a nice country club neighborhood, after serving barely half a year for each murder. He literally got away with murder(s).
What about revealing himself to his unsuspecting neighbors by testifying in the sensational trial? Doing so could arguably disrupt the life he’s built for himself since his release from prison. According to the man himself, that’s not at the root of his self-professed suffering.

So what wounded this evidently hard-hearted man? A betrayal of friendship and trust!  During the trial, Martorano said of Bulger and fellow gangster, Stephen Flemmi (in perhaps the only instance the expression has been used in earnest) “They were my partners in crime, they were my best friends, they were my children’s godfathers.” Of all the things that could cause The Basin Street Butcher pain, it was the snitching of his fellow murderers.

This is the kind of “irrational ethics” I’ve found through many interviews with convicted criminals. Usually the crimes for which they’re incarcerated aren’t the cause of their moral outrage, it’s that someone from their inside group inviolated a moral rule that was part of their moral code, in this case, cooperating with the “enemy.” This is the power of social norms in its most extreme form. Even though the usual societal rules are disregarded, another sort of code emerges and becomes the basis for judging one’s actions. So it’s “okay” to kill a person outside your in-group for stealing or talking to the cops, but it’s crossing the ultimate line to do so within the group. All that said, you really have to wonder what their get-togethers were like.

Ask Ariely: On Tipping, Attachment, and Hoarding

______________________________________________________

Dear Dan,

I work as a waiter in Waikiki, and sometimes to pass the time I conduct mini-experiments with customers, altering my behavior and attitude from day to day and seeing if it increases tips (in case you were wondering, seeming sad nets the most tips).

I have noticed that those paying with credit cards leave bigger tips, but it varies by card: American Express users tip the most, those with Visas a little less. Discover card users are by far the worst. I can’t quite figure this out.

—V 

One possibility is that wealthier people get American Express cards, the less affluent Visa, and the least well-off Discover—and they tip accordingly. You should be able to test this hypothesis by looking at their spending patterns—for example, how much they spend on wine.

Another possibility is that credit cards have a priming influence. If a person takes out an American Express card and looks at it, its reputation as a premium card might make the owner feel richer and therefore more generous. These feelings would diminish with a Visa card and be present even less with a Discover card (which generally is of more modest repute).

My guess is that both of these hypotheses play a role in what you’ve observed. To be sure, we would need to experiment by having a group of people with multiple kinds of credit cards pay in similar situations using different cards. Then we’d see if and how they change their spending.

______________________________________________________

Dear Dan,

I work with many entrepreneurs in their early innovation stage and am always intrigued by the strong (irrational) attachment they develop to their idea, often leading to their being blind to reality and to wasting time and money. How quickly do we get irrationally attached to our ideas? Is it based on elapsed time or on specific actions we take (such as presenting the idea to others)? What can be done to cure this?

—Omer 

The problem, of course, is not just with entrepreneurs. From time to time we all experience someone in a meeting who says something random, and not particularly smart, but then insists that we follow up on his or her brilliant suggestion.

A few years ago, Daniel Mochon, Mike Norton and I conducted experiments about what we called “the IKEA effect”: As the instructions to build something become more challenging and complex, we love even more what we have created. We also showed that this effect takes place rather quickly. In perhaps the most interesting and irrational part of the whole story, we found out that we also mistakenly think other people will share in our excitement over our inferior creations.

What can we do about this? We could try to create an environment where ownership is less powerful or less associated with particular individuals. But if we manage to reduce or eliminate the feeling of ownership, are we also eliminating commitment and motivation? Maybe we should try to increase this sort of proprietary attachment. (And by the way, now that I have finished, I love my answer and think that it is very insightful.)

______________________________________________________

Dear Dan,

After I’ve bought an expensive or limited-edition scotch, I worry about drinking the bottle too quickly or being unable to find more once it’s gone. So partly opened bottles in my closet keep accumulating. Any advice on how to enjoy my scotch rather than hoarding it?

—Jonathan 

The problem with hoarding (collecting) is thinking about it as one decision at a time. I would either try to think about such questions from a broader perspective (“Would I be interested in getting 24 more bottles?”) or set up a rule for the number of bottles that you can have in your house at one time (let’s say 10). Then you’d have to finish a bottle or give it away before you acquire another.
