Stopping/preventing (inhibition) distraction is difficult.

Inhibiting action potential is expensive and contributes significantly to ego depletion. If adequate resources are not availabile, inhibition opportunities start failing and can become beholden to impulses. Stopping an action that has started is significantly more expensive than preventing it; having a name for actions that should be prevented helps bring them to attention before starting the action.rR1
