Oaten and Cheng did one more experiment. They enrolled forty-five students in an academic improvement program that focused on creating study habits.11 Predictably, participants’ learning skills improved. And the students also smoked less, drank less, watched less television, exercised more, and ate healthier, even though all those things were never mentioned in the academic program. Again, as their willpower muscles strengthened, good habits seemed to spill over into other parts of their lives.
