The problem it solves

What if the easiest way to stop a habit is never to meet its trigger?

The concept

A habit can’t start if its cue isn’t there. Removing or reducing cues — putting the phone in another room, not keeping sweets in the house, taking a different route home — stops the habit before it begins.

Sometimes you can change the environment around the cue instead: the sofa where you snack becomes the reading chair; the browser that opens to social media opens to a blank page.

Avoiding high-risk contexts is a legitimate strategy where it’s sensible — skipping the shop that always tempts you, for a while. It isn’t weakness; it’s working with how habits function.

Why it matters

Stimulus control — changing or avoiding cues — is a core behaviour-change technique, and research on self-control suggests acting before temptation arrives is more effective than resisting it in the moment.

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

Ruth scrolls in bed for an hour each night and sleeps badly.

The ordinary first approach

She should set a firm rule to stop scrolling at 11pm.

With the idea

She charges her phone in the kitchen and keeps a book on her pillow.

What changed

The cue — the phone within reach in bed — is gone, so there’s nothing to resist.

Easy to get wrong

• Leaving the cue in place and relying on a rule.
• Avoiding so many situations that life shrinks — choose the high-risk ones.
• Forgetting that digital cues count too.

Try it now: Remove one cue today

1. Pick the most common trigger of a habit you want to change.
2. Ask: can I remove it, move it out of sight, or avoid that situation for now?
3. Make one change before the day ends.

Apply it to one of your habits

For one habit you want to change, which cue will you remove or reduce?

Reflect

• Which of your unwanted habits has a cue you could simply remove?
