When the Mind Wanders, Happiness Also Strays
By JOHN TIERNEY
And now, welcome back for the hypothesis of our experiment: Wherever your mind went — the South Seas, your job, your lunch, your unpaid bills — that daydreaming is not likely to make you as happy as focusing intensely on the rest of this column will.
I’m not sure I believe this prediction, but I can assure you it is based on an enormous amount of daydreaming cataloged in the current issue of Science. Using an iPhone app called trackyourhappiness, psychologists at Harvard contacted people around the world at random intervals to ask how they were feeling, what they were doing and what they were thinking.
The least surprising finding, based on a quarter-million responses from more than 2,200 people, was that the happiest people in the world were the ones in the midst of enjoying sex. Or at least they were enjoying it until the iPhone interrupted.
The researchers are not sure how many of them stopped to pick up the phone and how many waited until afterward to respond. Nor, unfortunately, is there any way to gauge what thoughts — happy, unhappy, murderous — went through their partners’ minds when they tried to resume.
When asked to rate their feelings on a scale of 0 to 100, with 100 being “very good,” the people having sex gave an average rating of 90. That was a good 15 points higher than the next-best activity, exercising, which was followed closely by conversation, listening to music, taking a walk, eating, praying and meditating, cooking, shopping, taking care of one’s children and reading. Near the bottom of the list were personal grooming, commuting and working.
When asked their thoughts, the people in flagrante were models of concentration: only 10 percent of the time did their thoughts stray from their endeavors. But when people were doing anything else, their minds wandered at least 30 percent of the time, and as much as 65 percent of the time (recorded during moments of personal grooming, clearly a less than scintillating enterprise).
On average throughout all the quarter-million responses, minds were wandering 47 percent of the time. That figure surprised the researchers, Matthew Killingsworth and Daniel Gilbert.
“I find it kind of weird now to look down a crowded street and realize that half the people aren’t really there,” Dr. Gilbert says.
You might suppose that if people’s minds wander while they’re having fun, then those stray thoughts are liable to be about something pleasant — and that was indeed the case with those happy campers having sex. But for the other 99.5 percent of the people, there was no correlation between the joy of the activity and the pleasantness of their thoughts.
“Even if you’re doing something that’s really enjoyable,” Mr. Killingsworth says, “that doesn’t seem to protect against negative thoughts. The rate of mind-wandering is lower for more enjoyable activities, but when people wander they are just as likely to wander toward negative thoughts.”
Whatever people were doing, whether it was having sex or reading or shopping, they tended to be happier if they focused on the activity instead of thinking about something else. In fact, whether and where their minds wandered was a better predictor of happiness than what they were doing.
