Creating cues

A habit needs a trigger. Designing the reminder is half the work.

The idea

Every habit needs a trigger. Much of our behaviour is prompted by cues we don’t notice: a time of day, a place, a person, an emotion, or the action that came just before. Designing the cue is half the work of building a habit.

Visible cues are powerful: running shoes by the door, a book on your pillow, a water bottle on your desk, a fruit bowl on the table. Time-and-place cues work too: “at 7am in the kitchen”. So do reminders — though alarms often become background noise if overused.

Cues can also be removed. If a habit you want to break has a cue — seeing your phone, passing a shop — hiding or avoiding the cue is often easier than resisting the urge.

Why it works

A good cue makes a habit happen on its own, without relying on memory or on how motivated you feel that day.

A real example

The situation

Ling wants to practise guitar daily, but her guitar lives in its case under the bed and she rarely plays.

What happened

She puts the guitar on a stand in the living room, next to her favourite chair. Seeing it, she picks it up most evenings, often just for ten minutes.

The takeaway

Moving the guitar into sight did more than any amount of intention.

Use this when you are…

• you keep forgetting a habit
• a habit depends on motivation
• you want to break a habit that has a clear trigger

Common mistakes

• Relying on memory alone to trigger a habit.
• Setting so many alarms that you ignore them all.
• Leaving cues for unwanted habits in plain sight.

What the evidence says

Moderate evidence: Several studies support it, but the effects are smaller, the studies are fewer or less rigorous, or results vary between groups.

Research on habits shows behaviour is strongly driven by contextual cues, and changing cues is an effective way to build or break habits. Specific cue designs vary in effectiveness between people.

Where this comes from: Habit formation research.

Fields that study this: Behavioural science.

Try it now: Place a cue

1. Choose a habit you want to do more often.
2. Decide what object or reminder would prompt it.
3. Put it where you will see it at the right moment.

Questions to think about

• What cues trigger your current habits, good and bad?
• Where could you place a cue for a habit you want?

Try this today

Place one visible cue for a habit you want to build.

Afterwards, ask yourself

Did the cue prompt the habit, and how often?

Words in this lesson

• Cue — A trigger that prompts a habit — a time, place, feeling, person or preceding action.
• Habit — A behaviour that has become automatic through repetition in a stable context, so a cue triggers it with little thought.
