The problem it solves

If you really want to stop a habit, why doesn’t deciding to stop work?

The concept

An unwanted habit is a learned link between a situation and an action, often with a real payoff. Deciding to stop doesn’t remove the cue, the ease or the payoff — so the next time the situation arrives, the habit is still pulled into action.

Trying to resist it head-on, over and over, is tiring and unreliable. People who seem to have great self-control tend to meet fewer temptations in the first place, because their surroundings and routines keep them away.

So the approach in this module is to redesign the system: understand what starts the habit and what it gives you, change the situation around it, and give the same cue a better response.

Why it matters

Research on self-control suggests strategies that change the situation are generally more effective than in-the-moment resistance, and that habits — good ones — help explain why some people seem to need less willpower.

Research-supported: Good studies support it, but there are fewer of them, the effects are modest, or they come from a narrow set of situations.

See it happen

Sofia wants to stop snacking late at night. Each night she promises herself she won’t, and most nights she does.

The ordinary first approach

She needs to be stronger and stop giving in.

With the idea

She looks at the system: the snacks are in plain sight, the habit happens while watching TV, and it helps her unwind. She moves the snacks, and makes tea part of unwinding.

What changed

She stopped fighting the habit at its strongest moment and changed what that moment contains.

Easy to get wrong

• Treating every slip as proof of weak character.
• Relying on resisting at the exact moment the habit is strongest.
• Removing a habit without replacing what it gave you.

Try it now: Look at the system, not yourself

1. Pick one habit you want to change.
2. Write where it happens, what starts it, and what it gives you.
3. Circle one thing in that system you could change this week.

Apply it to one of your habits

For one habit you want to change, what part of its system — place, cue, ease or payoff — will you work on first?

Reflect

• How often have you tried to change a habit by willpower alone? What happened?
