What actually changes during a stressful weekChecking frequency is not stable from week to week. This reframes who the heaviest checkers during a stressful week actually are. For someone without one, it just removes the only regulation tool they had, at the worst possible time to be without it. The regulation research points to something more specific and more fixable: the check is filling a short gap that a person has not yet built another way to fill. Without that second option, the phone keeps winning by default, not because anyone is addicted to it, but because it is the only tool within reach.
