Cues to action: put the trigger in your field of view

A cue to action is the visible trigger that turns an intention into a behavior. Place it where you will be standing at the moment you need to act.

Why it works

A cue to action is the prompt that converts a held intention into an actual behavior — the term comes from the Health Belief Model, where a cue to action is the trigger (an internal symptom, a reminder letter, a visible object) that moves someone who already believes they should act into acting. Intention on its own is a poor predictor of behavior; the gap is largely a matter of whether anything prompted the behavior at the moment it was possible. Out of sight, out of mind applies to healthy behaviors as much as to temptations. Research on food salience shows that placement and visibility are among the most powerful predictors of what people eat — healthy options placed at eye level or in clear containers are chosen more than identical options placed lower or in opaque containers. The visual cue activates the habit loop before a competing cue can.

How to do it

1. Place the tool or starting item for the behavior at the spot where you will need it (gym bag by the door, water bottle on the desk, book on the pillow).
2. Use visibility to the "right" past self: set out tomorrow’s tools tonight, when your motivation to prepare is likely higher than your morning motivation to start.
3. Remove or cover visual cues for competing behaviors (phone face-down, snacks in opaque containers).

Evidence

Visual salience effects on behavior choice are well-replicated in food and retail contexts (choice architecture literature). The application to habit cues is principled and used in most behavior-design frameworks, though direct RCT evidence for non-food habit cues is thinner. The "cue to action" construct is grounded in Rosenstock’s Health Belief Model, and Neal, Wood & Quinn’s habit research explains why a visible cue in a stable context fires the behavior automatically before a competing prompt can. (observational)

Strongest evidence is in food/retail; extrapolation to non-food habit cues is plausible but with less direct experimental backup.

Common mistake

Leaving the healthy-behavior cue in the same visual field as the competing-behavior cue, so the two are in equal contest rather than one having a salience advantage.
