You Can’t Simply Decide to Be a Different Person

When I was a kid, my dad did something on family vacations that perplexes me to this day: He ran. Every day, at least four or five miles, rising before the sun and before anyone else was awake. He wasn’t training for anything. He wasn’t trying to lose weight. There was no specific goal, no endpoint, no particular reason he couldn’t take the week off while in the greater Disney World metropolitan area, which, in July, is hotter than the surface of the sun.

Or at least, many researchers have concluded that it does not account for an enormous amount of observed human behavior, according to the psychologist Wendy Wood. In her book Good Habit, Bad Habit, she explains that for the latter half of the 20th century, psychological scholarship more or less affirmed its righteousness. Attitude leads behavior, the theory went, and the circumstances in which you exist aren’t that important to the choices you make. Individuals do certain things and not others mostly because of their own conscious decisions; your fate is largely in your own hands. You can see how this logic permeated culture: The self-help and diet industries boomed, the government slashed the social safety net’s tires, the 1970s became the Me Decade.
