Every means of confession creates a kind of person who confesses. You become who you are by saying what you did. The details make a difference. That pronoun, “I,” feels one way when you say it as part of a formula, in the dusk of a confessional, to a priest you cannot see behind the metal grille he blesses you through. Rambling in the well-lit office of a psychiatrist, “I” feels very different.
—Moira Weigel, writing for The New Inquiry about FitBit activity trackers and the nature of confession (“Like confession and therapy, activity trackers promise to improve us by confronting us with who we are when we are not paying attention,” writes Weigel).
