The reason boredom precedes most relapse

The abandoned routine does not return during a crisis. It returns on a wet Tuesday with nothing scheduled, when there is no obstacle to overcome and no reason to be anywhere. The dangerous condition was not difficulty. It was the absence of anything to attend to.

What everyone sees

Boredom is treated as a mild inconvenience, the low end of a scale of unpleasantness, and therefore an unlikely cause of anything important. That underestimates what it is. It functions as a signal that current activity is failing to engage attention, and signals demand responses rather than waiting politely.

What is actually happening

Eastwood, Frischen, Fenske and Smilek define boredom as an aversive state of wanting but being unable to engage attention, distinguishing it from tiredness or apathy and locating it in the attention system rather than in mood. Wilson and colleagues found participants left alone with nothing to do for fifteen minutes rated the experience as unpleasant and, in one study, a substantial share of them chose to self-administer an electric shock they had earlier said they would pay to avoid — an indication of how much the unoccupied state motivates action. The implication for behaviour change is structural rather than motivational. An unfilled interval creates pressure to act, the practised routine is the cheapest available action, and no failure of resolve is required for it to be selected.

Why it stays hidden

The mechanism hides because empty time is invisible in planning. Schedules record commitments, so an afternoon with nothing in it appears as a resource rather than as a risk. The person plans for temptation and difficulty, and is defeated by a gap that no plan describes because nothing was supposed to happen in it.
