Dear Dan,
I consider myself a steadfast atheist, but I have an irrational dilemma: Every time I want to throw away things that I no longer need, I find myself unable to chuck out anything that belonged to my parents. I can’t even part with their old pictures, which I have digitized and stored permanently on my hard drive. Am I being ridiculously superstitious?
—Eve
Religious belief and superstition aren’t really the same thing. Paul Rozin of the University of Pennsylvania has done excellent research showing that we are all superstitious, to some extent. In one of his experiments, participants were asked to throw darts at a target and were rewarded the closer they got to its center. Sometimes the center was the image of a beloved figure like President John Kennedy; sometimes it was someone widely despised, like Saddam Hussein.
People hit the bull’s-eye more for Saddam and missed more for JFK. They knew, of course, that pictures aren’t the same as people, but they still attached some of the person’s symbolic meaning to the images, which made it harder to harm them.
This type of emotional link means that when you think about throwing out your parents’ belongings, you feel as if you are discarding a part of them. My advice? Send the items that you don’t want but can’t destroy to your siblings or other relatives and let them deal with them.

Dear Dan,
I’m renting an apartment with two friends. One of them is moving in on August 24. I plan to move in on August 29, and the third friend is planning to join us in early September. Our landlord will charge extra rent for those days in August. Who should pay?
—Randy
The right way to split the cost depends on the timing and sequencing. If the lease was always set to start on August 24, then you should all split the cost because you all undertook the responsibility of starting the contract together. But if the contract could have started on any day, and your first friend pushed you into starting it on August 24, that friend should be on the hook for funding the extension. Fairness mandates considering the process here, not just the final outcome.
That said, remember that you’re all going to be roommates, perhaps for a long time, and starting your joint life together by protracted haggling may open the door to years of annoying accounting discussions (“You had an extra swig of the milk, so you owe me 75 cents”) rather than years of deep friendship. With this in mind, I suggest dividing the rent equally—but also asking the people moving in early to do more to set up the apartment, call the cable company, get basic supplies and figure out where the furniture goes. That way, they will contribute more to the overall endeavor but in a way that is compatible with long-term friendship.

Dear Dan,
We have lots of meetings at my office, and when I speak up, I often worry that as a rather junior female employee, I don’t sound as if I have enough authority. Any advice about how to seem more commanding?
—Katherine
One of the best ways to increase your perceived authority is to start using acronyms. My favorites are WAG (Wild-Ass Guess) and SWAG (Scientific Wild-Ass Guess). My SWAG is that deploying a few well-placed acronyms the next time you make a point will give your gravitas quotient (or GQ) a boost.

Dear Dan,
A big local employer just announced that it is about to change its standard workday from eight hours to five. I suppose many people barely do two or three hours of good work a day anyway, but is shrinking the workday so drastically a good idea? in italics
—Bernard
To think this through, let’s break down our workday into three modes: productive, thoughtful, useful work; mindless, detail-oriented work that doesn’t demand much concentration but must get done; and, of course, wasting time.
When the workday is slashed from eight hours to five, which of these modes is likely to give way? If the three lost hours would otherwise have been spent procrastinating, the change is all to the good: We can waste time better on our own. And if it comes at the expense of drudge work, many people will just become more efficient at their more mindless tasks, with a minimal drop in productivity.
But I fear that those three hours will come at the expense of the most productive category of work. That’s because everyone likes the sense of satisfaction from making progress. We feel virtuous after emptying our email inbox or checking off items on our to-do lists. If the workday shrinks, we’d rather sacrifice real progress than surrender that feeling of gratification.
If we now split an eight-hour workday between one hour of thumb-twiddling, four hours of drudgery and three hours of serious work, I’d predict that the shorter workday will mean a half-hour less of wasted time, an hour less of mindless work and an hour and a half less of meaningful work.
This is just an educated guess, of course. If I ran your workplace, I would start by cutting the workday by 30 minutes, see what this does to productivity and adjust from there.

Dear Dan,
When you have to deliver two pieces of news, one bad and one good, which should you start with? I’ve always been told to deliver the bad news first, but I worry that its impact could be so distracting that the recipient won’t pay attention to the good news that follows.
—Galia
Why pick from just this constrained set of options? Is there really nothing else in the universe to share? I’d come up with another piece of good news to start with, such as the fact that we have eradicated smallpox and polio could be next—admittedly less relevant but undeniably cheerful. You can then sandwich your bad tidings between good ones.

Dear Dan,
While writing a document on my laptop with a colleague, he kept pointing to my screen and sometimes touched it with his finger. I found this incredibly annoying—and a strange invasion of privacy. I wouldn’t have minded if my co-worker had touched my arm, but I bristled when he touched my screen. What gives?
—Kim
After reading this, I asked a few people nearby to touch my laptop and then my elbow, and I felt the same irritation. I suspect that’s because once people touch our computer screens, we can’t avoid seeing the gross residue that their fingers leave, but we don’t think about the oil and dead skin cells left behind when somebody nudges us on the arm. Consider this more evidence that ignorance can be bliss.

Dear Dan,
At a holiday potluck that I attend each year, the hostess asks each guest to bring a specific dish. We always wind up with too much food, but the hostess never asks us whether we would like to take any leftovers home. I think that the food I made and brought should be considered mine. So who do the leftovers belong to, the hostess or the cook/guest?
—Sigrid
This is a tricky one. Usually, if we are invited to someone’s house for dinner and bring, say, a bottle of fine whiskey, we wouldn’t expect to take the rest of the bottle back home with us. But a potluck isn’t your standard dinner party, and it isn’t clear what rules apply. You gave the food, which was accepted by the host—but she did so on behalf of the group, which didn’t finish it.
Ethics aside, I see three practical ways to resolve the problem. First, you could make something that is physically hard to separate from the dish in which you brought it. If, for instance, you brought crème brûlée in a large ceramic dish, you’d make it clear that the dish was yours, and because it would be difficult to separate it from the leftover dessert, you would get to take them both home.
Alternatively, you could bring your contribution in two containers, hand one to the host and tell her that you have another container in case your fellow diners polish off the first one. You wouldn’t have to hand over the second part of your offering unless it turned out to be needed, and you’d have a decent shot at getting to take it home.
Or you could whip up a crowd-pleasing recipe that you happen not to like. The point of a potluck is to have fun with friends, not to fret about who gets what at the end. So just make something you don’t care for. You won’t care who inherits the leftovers, and you’ll enjoy the party more.

Dear Dan,
I went to the bathroom at a new restaurant in town only to find a large, modern-looking stainless-steel urinal, without partitions, which put everyone in plain view of his fellow patrons. I tried to finish my business quickly and get out of there. Am I the only one made uncomfortable by such arrangements?
—Greg
Actually, many men are made uneasy by such bathroom settings, but I suspect that you didn’t finish your business any faster.
In 2005, my students and I carried out an experiment at MIT. Sometimes, we had one of our students stand at the middle urinal in the men’s room, pretending to go and waiting for unsuspecting visitors. Other times, we didn’t have anyone from our team at the urinals. In all cases, we had a student hiding in a nearby stall with a recorder.
That let us pick up two aspects of urination: its onset (from the time a subject situated himself at the urinal to the moment when we first heard liquid sounds) and its duration (until those sounds stopped).
We found that men took longer to get going when they had company nearby, presumably because of social stress. But once they started, they finished faster—again, presumably because of stress and the desire to get out of there. The total amount of time was slightly slower than when men were left alone.
Of course, our participants were undergraduates with splendid bladder control, so we might need to repeat this study with a more mature population.

Dear Dan,
We often greet each other by saying, “How are you?” But most of us probably don’t really want a long answer. Why do we do this?
—Warren
Dear Dan,
To reduce cheating at the high school where I teach, we ask students to sign an ethics code before each exam and on every paper they submit. I’d estimate that they sign the code at least once a week. Your own research, I gather, shows that getting students to sign a similar ethics code just once helps to reduce cheating. What about signing it more often? Does overuse make it ineffective?
—Elliott

Dear Dan,
I find it easy to avoid reckless spending. I don’t own a credit card because I hate the concept of interest, and I’m paying my daughters’ college tuition (they know that they have to pay me back) because if they took out loans, I’d have to co-sign and might be on the hook for the tuition and interest. Am I just more rational than other people?
—Wei
See the original article in the Wall Street Journal here.
As spending money becomes easier (think of credit cards, Apple Pay, and Google Wallet, among others), we have more opportunities to spend our money well, and to spend it not so well. In collaboration with Qapital, we have made a survey to learn about what kinds of purchases people feel good about, and what kinds they regret. Note that this link and survey is secured by the highest possible internet and bank standards.
Please help us by participating in this short study and reflecting on your past transactions. We will randomly choose some participants to get the chance to have a 30-minute chat with me. You have our immense gratitude.

Dear Dan,
I live with several roommates, and our landlord recently refunded some of our rent to make up for construction-related hassles in the building. What should we do with the money? We could divide it among ourselves, use it for house supplies or get a bigger TV to watch movies together. How should we think about this?
—Kristen
I vote for doing something fun with the windfall—ideally something that would let all the roommates have a new experience together. Your relationships with each other are, I suspect, the biggest contributing factor to your happiness (or misery) at home: When they are good, life smiles on you, and when they are bad, you probably tend to stay out as much as possible.
Doing some activity together—say, sailing, skydiving or learning a new skill—would bring all of you closer and encourage you to be nicer to each other. You would ordinarily have a hard time asking everyone to chip in for an expensive group activity; after all, you are roommates, not standard friends.
But a refund from your landlord should feel more like free money—cash that no one planned on having and that everyone can probably manage without. That should make it easier to persuade your roommates to partake in some group-bonding activity.
Looking for the ideal skill to learn together? I would suggest a cooking class. You’ll not only have fun learning something new, but you’ll also enjoy better food—and perhaps the joy of cooking for each other for a long time.

Dear Dan,
It has increasingly struck me that humans feel pain much more intensely than pleasure. Is this true, and is there a reason why pain affects us more?
—Brian
Yes, we do experience pain much more intensely, which makes sense from an evolutionary perspective. In general, nature wants to teach us to seek things that are good for us or the species (food, warmth, sex), so these give us pleasure. Nature also wants us to stay away from dangerous things (predators, toxins, fire), so these give us pain.
One might imagine that the things nature wants us to seek would give us pleasure, while the things that we should avoid would leave us feeling neutral. But the benefits and harms of life aren’t symmetrical. A good outcome (a delicious piece of fruit, for example) can give us some modest benefit, but a bad outcome (say, poison) can kill us—which is a very significant downside.
If the evolutionary priority for us is to seek good outcomes but especially to avoid bad ones, then our tendency to focus on pain (and potential pain) is a pretty effective way to shape our behavior. Even during painful times, I’ve found that a somewhat comforting thought.

Dear Dan,
A friend of mine from work is turning 45. What should I get him?
—Janet
If he doesn’t have reading glasses, get him a pair. People generally delay getting reading glasses, because it is hard to recognize the slow deterioration of our vision and because it means admitting that we are aging. If you give your friend a pair, you will spare him the procrastination, and he will immediately realize that he has been living in a blurry world. He might not immediately feel deep appreciation, but it would still be a very helpful present.

Dear Dan,
I am 65 and have been going to the same hair salon for ten years. I have gotten to know well the experienced stylist who cuts my hair. Recently, she had to cancel two appointments, so I got my hair cut by her former protégé, who works at the same shop. I discovered that I like the way the protégé cuts my hair better. I don’t see any way of switching to the younger stylist because of the social problems it will cause me and the stylists themselves. Both of them work the same hours on the same days.
I guess at my age, I just have to live with it. But I wonder, using my situation as an example, how can someone make such a change when faced with a similar dilemma?
—Alvin
I don’t think you have to resign yourself to worse haircuts. You could instead use a positive message to tell your long-time stylist that you’d like to switch. You could tell her that you are trying to make changes in as many areas of your life as possible—and that if she doesn’t mind, you would like to try the other stylist. At age 65, why not take the statement seriously and try to change some other things in your life and explore other new directions?

Dear Dan,
When my grandfather died in a house fire decades ago, he had been a blood donor for 70 years. I made it my mission to continue donating “for him.” I lived in Belgium at the time and donated with the Red Cross every 3 months.
When I moved to California, I decided to continue donating blood, but there was a problem: I had to lie on the questionnaire about whether I had spent time in Europe in the 1980s. The fear was contamination from mad cow disease. There was never a case of it in Belgium, ever, so I didn’t feel that I had to disclose that part of my past. After my most recent donation, the Red Cross became suspicious of my personal history, and now they have caught me. I am convinced that my blood will be destroyed and I will be barred from donating ever again.
I am beyond sad and feel that I broke my promise to my dead grandfather. What advice do you have to offer me?
—Christie
From time to time, we all experience rules that we think are strange, crazy, over strict, applied inappropriately and so on. But we also have to remember that very large organizations like the Red Cross have to create some rules in order to operate efficiently and safely. It would have been better not to lie to the Red Cross, even at the cost of not being able to donate blood.
As for your commitment to your grandfather, I think that you should understand it only as doing your best to donate. You have no control over whether the Red Cross accepts your blood, and you should not blame yourself. Given that you still want to honor your grandfather, how about donating money to the Red Cross or a local burn unit?

Dear Dan,
What’s the best way to deal with a difficult teenage boy? He stays out as much he can; he’s rude and dismissive; and he refuses to do chores. Whenever he’s away from home, he’s charming. Any suggestions?
—Claudia
The good news is that he is charming away from home, which means that he is capable of being nice. Sadly, he does not seem to be interested in acting this way with you.
What if you set up a webcam in a very visible part of the house and made it clear that his behavior would be streaming to Facebook for his friends to see? That way, he might bring his outside behavior into the house. After a few weeks of this, he might develop new habits toward his family, and you could turn off the camera (but maybe keep it there unplugged, just as a reminder).
See the original article in the Wall Street Journal here.
Dear friends,
There’s no question that we are becoming more and more dependent on our phones as a society. It’s less clear to me, however, what exactly we are doing on our smartphones, and how much time we are spending on each of these activities. If you would like to participate in a brief study, please answer a few questions about your app usage.
