Ask Ariely: On Honoring Housework, BE to Business, and Laundering Linens

Many women don’t feel recognized for all the work they do at home. When their husbands come home late from the office to something other than total bedlam, the oblivious men often fail to provide any appreciation or recognition. Would it help if women got paid for their housework? And if so, what is the best way to set up those payments?


I can’t think of any context in which one partner in a family should directly pay the other. But we do need to make sure that earning inequality doesn’t turn into power inequality.

One of the best (and worst) things about money is that it is easy to measure. So each partner’s financial contributions to the household are very clear, and differences can be overemphasized.

Consider a couple in which Person A earns much more than Person B, but Person B does everything else for the household. In such a case, A’s contribution to the relationship is easily quantified (bringing home most of the bacon), whereas B’s bit (taking care of the house, raising the children, dealing with paperwork, bills and so on) can’t be measured as precisely.

If the couple focuses on what’s easy to measure, A’s contribution looks more central. So A could feel more deserving, entitled and commanding while contributing less overall.

There is no magical solution to this problem, but one good step is to deal directly with the flow of money. Start by having one joint checking account for all income and ongoing expenses. On top of that, open two separate savings accounts (one for each partner), and split all savings equally into them.

Legally speaking, this type of accounting doesn’t make any difference, but in psychological terms, it makes a key statement about equality in financial contributions. It could weaken the link between financial contribution and power and offer a more holistic view of contributions to family life.


What can businesses learn from your academic field of behavioral economics?


As with any other scientific endeavor, my field has reached, over time, a better understanding of its domain—human behavior. The process has been slow, but the lessons are accumulating.

We have found, for example, the principle of loss aversion: It turns out that we humans hate losing more than we enjoy gaining. Or the IKEA effect—the finding that, once we take part in making something (like IKEA furniture), we start really liking it, and we assume that other people will like our creation too. These are discoveries that businesses can use in developing their products and services.

For all that we’ve learned, however, I suspect that the most important lesson is how little we know—the lesson of humility. We understand a great deal about human behavior, but we also have a lot of gaps, assumptions and blind spots. By training, social scientists are happy to admit how little we really know and much room there is for improvement.

If businesses adopted this approach, trusting their intuitions less and relying on research more, they would get a very high return on investment. Admitting our shortcomings is an important first step.


We host a lot of overnight guests. Should I change the sheets on the guest bed every time a new guest arrives, even if the last one only stayed with us for one night? —Debbie

I am sure that you don’t want to tell your new guests that they are using “only slightly used linens,” and I am almost sure that you don’t want to hide things from your guests—so yes, change the sheets every time.

Please Don’t Steal the Charmin

August 1, 2012 BY danariely

A Chinese tourist destination decided to experiment with offering free toilet paper, the Wall Street Journal reports. Rather than the usual procedure in China, where people bring their own toilet paper, in Qingdao they now encounter a toilet paper dispenser when they enter the public restroom (and, naturally, pass it again on the way out).

Now that the dispensers have been in the bathrooms for a month, it has become clear that visitors to Qingdao’s restrooms take an astonishing amount of care for their personal hygiene. Two kilometers (1.24 miles) of toilet paper disappear each day.

In this case, the excess T.P. use seems to reflect our findings with other forms of cheating and stealing: most people are cheating a little, rather than a few people cheating a lot. Of course, there are exceptions.

The toilet paper scenario meets the right conditions for people to cheat: they’ve got the opportunity and face no consequences for taking a bit extra, they can use the toilet paper later, and they can rationalize their behavior. They might tell themselves that the government is paying for their bathroom use in general, not only for that specific restroom; or that it’s expected that they’d take extra on the way out; or that they’ve already paid for it in the form of taxes; or that the government deserves what it gets. They’ve easily justified a way to walk out with wads of toilet paper and an untroubled conscience.

But why steal something like toilet paper?

One explanation probably has to do with the power of free. Maybe Qingdao’s bathroom users are so enchanted with the idea of FREE toilet paper that they would take it in any case, regardless of what they know about its value or usefulness.

Another explanation that pops up a lot with government-provided goods is the tragedy of the commons. The theory goes that individuals will use a limited resource (like commons for grazing animals) in an unsustainable way, so long as they get the full benefit and the harm is spread across the group. In the case of the toilet paper, the theory suggests that people use no more than they need when they have to pay for it individually. But when the cost is spread out across Qingdao, they are happy to overuse the resource. The usual prescription is to make individuals pay for the resource on their own—in other words, to go back to the days without free toilet paper.

But there might be a better solution. We can take research from behavioral economics to think of ideas that may be less strict than taking away the free toilet paper and, instead, simply push people toward lighter use of the product. How about replacing the landscape paintings above some dispensers with a picture of watching eyes—a tactic that has effectively encouraged people to clean up after themselves and pay on the honor system.

In Qingdao, restroom managers have attempted to confront their problem by posting a poetic reminder of social responsibility:

Convenience for you,
convenience for me,
civility is there for all to see.
My paper use, your paper use,
conservation is up to us.

The sign hasn’t had a noticable effect yet, but it may be on the right track. Reminders like the poem sometimes work (p.41, The (Honest) Truth About Dishonesty) to keep people from stealing toilet paper. The Qingdao bathroom poets appeal to bathroom users’ social norms (“civility is there for all to see”) and allude to future benefits (convenience and conservation)—tactics that have been shown to work in getting people to wash their hands. But getting some sort of assent—like a signature—may be even more effective.

For example, bathroom visitors could sign in under a poem like this:

Future benefits and social obligations
Should outweigh your current temptations
You agree not to steal by signing below
You’ll take just what you need when you need to go

Sign here:    _______________________



Of course, if the bathroom management is going to ask people to sign anywhere, they might also want to keep watch over the “free” pens.
