Make the right cue salient at the decision moment

Reminders and cues placed where the decision happens shift behavior without any other change.

Why it works

Attention is a scarce resource and we act on what is in our attentional field at the moment of decision. A cue that is not visible at the decision point effectively doesn’t exist. Salience nudges exploit this by placing reminders, prompts, or the desired behavior itself in the exact physical or temporal location where the choice is made.

How to do it

1. Identify the precise moment of choice for the behavior you want to change (opening the fridge, sitting at your desk, picking up your phone).
2. Place a physical cue for the desired behavior at that exact location (vitamins next to the coffee maker, book on the keyboard, water bottle on the phone).
3. Remove or obscure cues for competing behaviors from that same spot.

Evidence

Point-of-decision prompts (stair-use signs next to elevators, calorie labels at purchase, fruit placed at eye level in cafeterias) are among the best-replicated nudges in behavioral public health research. (observational)

Point-of-decision prompt effects on exercise (stair use) are typically modest in size — meaningful at population scale but individually small. Salience fades with habituation; cues should be refreshed periodically.

Common mistake

Putting reminders where you’ll see them in calm moments (a sticky note on the bathroom mirror) rather than at the actual decision point where the competing impulse is strongest.
