Vox: The myth of self-control

Modern-day psychologists might not blame Eve for her errant ways at all. Because what’s true today was also true at the beginning of time (regardless of what story you believe in): Human beings are horrible at resisting temptation. [...]

The implications of this are huge: If we accept that brute willpower doesn’t work, we can feel less bad about ourselves when we succumb to temptation. And we might also be able refocus our efforts on solving problems like obesity. A recent national survey from the University of Chicago finds that 75 percent of Americans say a lack of willpower is a barrier to weight loss. And yet the emerging scientific consensus is that the obesity crisis is the result of a number of factors, including genes and the food environment — and, crucially, not a lack of willpower. [...]

The students who exerted more self-control were not more successful in accomplishing their goals. It was the students who experienced fewer temptations overall who were more successful when the researchers checked back in at the end of the semester. What’s more, the people who exercised more effortful self-control also reported feeling more depleted. So not only were they not meeting their goals, they were also exhausted from trying. [...]

The new research on self-control demonstrates that eating an extra slice of cake isn’t a moral failing. It’s what we ought to expect when a hungry person is in front of a slice of cake. “Self-control isn’t a special moral muscle,” Galla says. It’s like any decision. And to improve the decision, we need to improve the environment, and give people the skills needed to avoid cake in the first place.
