The Quantified Life

You know yourself pretty well. But what if a lot of your ideas about yourself — what makes you happy, healthy, and whole — turned out to be wrong? And how would you even find out? You’d probably start by becoming a self-tracker, piling up all kinds of data on your daily life. Then you’d analyze that data, and maybe you’d find that coffee doesn’t help you concentrate after all and that your sleep patterns aren’t correlated to your happiness. You’d almost certainly read The Quantified Life, a blog on self-tracking and self-experimentation. Seth Roberts, the self-experimenter Dubner and Levitt wrote about in 2005, makes frequent appearances.[%comments]
