How to Stop Making Tiny Mistakes That Make You Look Stupider Than You Really Are
"Where?" I said.
"The restaurant. Where we're meeting."
"Oh no," I said, looking down at my pajamas, which I was not only already wearing but had also splattered with the spaghetti sauce I'd just made. In a split, heart-sinking second, I knew what I was going to have to say, because I'd already said it so many times this year that it was laughable—and humiliating. "I forgot. I'm sorry. I don't know what happened. I didn't used to be like this."
That last phrase is one that so many of us say to ourselves. We didn't used to send our critical business email to the members of our mommy group. We didn't used to forget to add the eggs to the banana-bread batter. We didn't used to put antifreeze in the oil tank of the car—or commit any of those other mindless mistakes that now affect our lives.
This is why I turned to Sendhil Mullainathan, a professor of economics at Harvard. Though an authority in behavioral science, just last week this illustrious thinker forgot his glasses in his motel bathroom—a mishap that not only supports his theory about why all of us keep slipping up, but also provides some insight into how to prevent doing so.
Step 1: Realize It's Not YouLet's start from the beginning of Mullainathan's story. In order to start his job teaching this fall at Harvard, he had to move from New York to Boston. Because he had a small apartment, he allotted 24 hours for the project. The day of, he spent from 8 a.m. to 6 p.m. supervising the movers and packing. From 7 p.m. to 10 p.m., he drove up to Boston in the full van. Then he parked the van, spent the night in a hotel, woke up at 8 a.m., brushed his teeth, washed his face and left his very-much-needed glasses on the counter.
Every time we do something like this, Mullainathan says, we think, "I'm stupid!" Mostly, we believe this because we are convinced that we're the only ones who could have done it. There is no one else to blame. But (a) you're not stupid, and (b) feeling stupid is not the problem and will only cause you to feel discouraged and, frequently, to make more mistakes.
Step 2: Understand When You're DrunkSo what's going on? Though you might not realize it, you might well be "drunk" in terms of your brain's ability to process information. Let's say you've been working on an intense project—moving apartments or finishing a big presentation for work or finishing the fundraising plan for your child's school. In order to complete it, you focus on the project to the fullest extent possible, putting aside anything not related to its responsibilities.

Step 3: Plan Your Mistakes in AdvanceThe first step is looking ahead—the same way you would with drinking before a party. You know that there are certain tasks that take large amounts of focus and energy. For example, take packing up an apartment. After putting everything you own into boxes, you're going to have low bandwidth and be more liable to make small mistakes. In a perfect world, of course, you could give yourself some time to recover. But if you can't, just recognizing that you'll be "drunk" before, say, you hit the road in the van, will reduce the number of mistakes you do make, Mullainathan says, because your brain moves into a more conscious thought process about the problem.
Step 4: Identify Your RepeatersNow you know when you're going to make mistakes. But which mistakes? Shockingly, Mullainathan says, about 80 percent of the time we make the same handful of errors. Take leaving your glasses in your hotel room. You have done this before in some other form. You've left them at your friend's house. Or at the restaurant. Forgetting the glasses—or losing the car keys in the trunk of the car or sending an email to the wrong person—is what's known as a repeater. Once you've identified a time you'll be at low bandwidth, try making a list of specific things that will probably go wrong simply based on to your history of errors.
By telling yourself about a specific thing that may go wrong, Mullainathan says, it probably won't. Furthermore, you can also prepare yourself. One year before the move, Mullainathan had identified losing his glasses as a "repeater," and so he had bought two identical pairs the last time he went in for new ones—an act that allowed him to read the writing on his moving boxes and unpack once he'd finally arrived.

Step 5: Revamp Your Calendar—or Throw It OutRecognizing times of low bandwidth and dealing with common errors is helpful. But a more efficient solution might keep you from getting low bandwidth in the first place—in other words, keep from getting "drunk." It would be nice, of course, if we could just increase our bandwidth capacity, but research, Mullainathan says, has yet to prove a way to effectively do so. Our ability to focus simply has a limit.
Add to this: most of us think we can cope with our mentally taxing lives by managing our time. Let's say you're looking at your calendar for next week, the way that he did with the move. Most of us think about what we can fit, in terms of hours. We have the morning free so we fill it with the big meeting with the boss (10 a.m. to 12 p.m.). Then we have an intense lunch with the possible new client (12:30 p.m. to 2 p.m.). Then at 2:30 p.m., we're getting off early to take all three kids to all three after-school activities. Time-wise, this should work fine.
The meeting with a boss, however, takes a lot of bandwidth. You have to come up with a whole new ad campaign. Worse, at 11:40 a.m., you start thinking, "I really need to prepare for that lunch!" So you stop listening and generating new ideas. You then race to the lunch, now at mid-bandwidth and with even less creative and analytical skills. There, you also lose the last 20 minutes, because in your mind you're preparing the 2:30 p.m. pick-up and worried that you won't get back to the office in time and might forget the tutu for your daughter. "It's all doable, I have the time planned," you think, driving your kids first to ballet, then to hockey, then to pottery. Only to find the tutu in your backseat once you pull into the driveway.
What we need to do, says Mullainathan, is stop managing time and start managing our bandwidth. Of course, we can't just cut out activities and obligations. But when we sit down to plan our week, we can think about our schedules in terms of what our brains can reasonably handle—no matter what our bodies are capable of. For example, we can give ourselves just as many high-bandwidth activities but space them out differently or stagger them with low-bandwidth activities.
Step 6: Go on AutomaticAnother thing you can do is to transform certain high-bandwidth activities into low-bandwidth ones by making them "automatic." When you first began brushing your teeth, the activity took a lot of time and concentration. But as you did it over and over, you no longer had to think about getting the toothpaste on the brush (without squirting it all over the counter) and moving that big plastic tool over all your teeth (including the back side of your incisors). You can certainly do the same, repeating responsibilities at work or at home until they are, if not mindless, then less mindful. Serve the same breakfast for 30 days. Send an email in the same way 60 times (i.e., write, spell check, reread, send).
Moving, unfortunately, isn't something most of us can do with sufficient repetition to make it automatic. So what was the solution for this social scientist, other than to have a quick-fix after he'd already erred? "I should have done as I teach others," he says, with a sheepish laugh. "It wouldn't have taken much to keep me from losing my glasses. All I needed was an hour to recover from the move the next morning. In other words, I needed to sleep in a little later, eat breakfast and rest my bandwidth." In other words: The next time you get your brain drunk, consider giving it time to recover from the hangover.
