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 AskAriely@wsj.com.
I recently went to a restaurant that doesn’t take reservations. The maître d’ told me that the wait would be 20 minutes. Twenty minutes later, he said it would be 15 more minutes—and after that, 10 more minutes. It took just over an hour to get seated. How can I rationally decide when to wait—and when to cut my losses and go to another restaurant?
Let’s start with a basic issue: Are the hosts at restaurants all over the world lying on purpose about the wait, or are they simply (like most of us) overly optimistic about time? It’s tempting to suspect that they’re lying because it seems so unlikely that hosts, who have so much experience predicting wait times, can so often be so wrong. But I’m the same way: Every day, I think that I’ll leave work at a certain hour, and every day, my predictions get crushed. I also don’t seem to learn much from my prediction errors. So let’s not assume that the host is deliberately giving you a biased estimate.
The question now is what you can do about it. As an outsider, you have an advantage over restaurant hosts. You’re not trapped in their biased views, so you can develop a “fudge factor” and apply it to their estimate —maybe make it 1.5 times as long as the host’s estimate. So when the host tells you an expected wait time, multiply their estimate by your fudge factor and ask yourself if the food is worth this more realistic amount of time.
Then, if you do decide to wait, don’t look at your watch all the time—it only makes waiting more annoying. If it is a nice day, take advantage of the unscheduled time, leave your cell number with the host and go for a stroll. The street will probably be a fine environment for a chat with your dinner companion, and it will help you burn some calories in preparation for the meal—all good things.
When I drive home at night, I have to look for a parking spot in my neighborhood. Should I stay in one place and wait for a parking spot to become available, or should I drive around in circles in search of a free space?
I’m not sure there’s an objectively correct answer, but here are a few things to consider. On the one hand, you never know when and where a parking spot will free up, but you know for sure that driving around wastes more fuel than staying put. This suggests that waiting in one spot is the right approach. On the other, if you idle in place, you might be waiting at a location where everyone has already parked for the night, and if you drive around, you at least get to spread your risk and hedge your bets. And this suggests that driving around is the right approach.
But you should also consider the psychology of waiting: Staying put and doing nothing is much more annoying than being active. When we just wait, time passes more slowly, and patience wears thin. Regardless of how much fuel they might save, a lot of people would go crazy if they had to just sit in their cars and wait. So between fuel economy and mood maintenance, the best thing to do is to buy a fuel-efficient car and keep moving.
