Indeed, “stimulus-independent thought” or “mind wandering” appears to be the brain’s default mode of operation (1–3). Although this ability is a remarkable evolutionary achievement that allows people to learn, reason, and plan, it may have an [2, 4, emotional cost. Many philosophical and3] religious traditions teach that happiness is to be found by living in the moment, and[9] practitioners are trained to resist mind wandering and “to be here now.” These traditions suggest that a wandering mind is an unhappy mind. Are they right? Laboratory experiments have revealed a great deal about the cognitive and neural bases of mind wandering (3–7), but little about its emotional consequences in everyday life. The most reliable method for investigating real-world emotion is experience sampling, which involves contacting peo[14] ple as they engage in their everyday activities and asking them to report their thoughts, feelings, and actions at that moment. Unfortunately, collecting real-time reports from large numbers of people as they go about their daily lives is so cumbersome and expensive that experience sampling has rarely been used to investigate the relationship between mind wandering and happiness and has always been limited to very small samples (8, 9). We solved this problem by developing a Web application for the iPhone (Apple Incorporated, Cupertino, California), which we used to create an unusually large database of real-time reports of thoughts, feelings, and actions of a broad range of people as they went about their daily activities. The application contacts participants through their iPhones at random moments during their waking hours, presents them with questions, and records their answers to a database at www. trackyourhappiness.org. The database currently contains nearly a quarter of a million samples from about 5000 people from 83 different countries who range in age from 18 to 88 and who collectively represent every one of 86 major occupational categories. To find out how often people’s minds wander, what topics they wander to, and how those wanderings affect their happiness, we analyzed samples from 2250 adults (58.8% male, 73.9% residing in the United States, mean age of 34 years) who were randomly assigned to answer a happiness question (“How are you feeling right now?”) answered on a continuous sliding scale from very bad (0) to very good (100), an activity question (“What are you doing right now?”) answered by endorsing one or References and Notes Happiness, attention, and doing: Measuring Happiness Some motivation Measuring emotional content Data sets Analysis Songs Blogs Tweets Positivity Bias References Fig. 1.

Dashed line indicates mean of happiness across all samples. Bubble area indicates the frequency of occurrence. The largest bubble (“not mind wandering”) corresponds to 53.1% of the samples, and the smallest bubble (“praying/worshipping/meditating”) corresponds to 0.1% of the samples. 1. M. E.

Our analyses revealed three facts. First, people’s minds wandered frequently, regardless of what they were doing. Mind wandering occurred in 46.9% of the samples and in at least 30% of the samples taken during every activity except making love. The frequency of mind wandering in our real-world sample was considerably higher than is typically seen in laboratory experiments. Surprisingly, the nature of people’s activities had only a modest impact on whether their minds wandered and had almost no impact on the pleasantness of the topics to which their minds wandered (12). Second, multilevel regression revealed that people were less happy when their minds were wandering than when they were not [slope (b) = –8.79, P < 0.001], and this was true during all activities, Complex Sociotechnical including the least enjoyable. Although p minds were more likely to wander to pleasan Systems (42.5% of samples) than to unpleasant (26.5% of samples) or neutral topics (31% ples), people were no happier when thinkin Measuring pleasant topics than about their current activ Happiness –0.52, not significant) and were considera happier thinking about neutral topi Somewhen motivation –7.2,Measuring P < 0.001) or unpleasant topics (b = emotional P < content 0.001) than about their current activity Data sets bottom).

The nature of people’s activi plained 4.6% of the within-person variance References piness and 3.2% of the between-person vari happiness, but mind wandering explained of within-person variance in happiness and of between-person variance in happiness. T iance explained by mind wandering was independent of the variance explained by ture of activities, suggesting that the two w dependent influences on happiness. In conclusion, a human mind is a wan mind, and a wandering mind is an unhappy The ability to think about what is not hap is a cognitive achievement that comes at a tional cost. 12 NOVEMBER 2010 Policy = Brave New World 10 of 83 Complex Sociotechnical Systems 13 of 83 We’d like to build an ‘hedonometer’: I Measuring Happiness Some motivation Measuring emotional content An instrument to ‘remotely-sense’ emotional states and levels, in real time or post hoc.
