CORE DEFINITION

Many elevator 'close door' buttons and pedestrian crossing buttons at intersections are not actually connected to any circuitry (they are broken or fake), yet pressing them gives people a sense of reassurance and control.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Design for sense of control: During waiting (e.g., page loading), providing a progress bar or refresh button, even if useless, can effectively reduce user anxiety and maintain their sense of control.

The placebo button leverages people's need for a sense of control over 'action-feedback': even if the button is ineffective, the act of pressing it provides psychological control and immediate feedback, thereby reducing anxiety. The mechanism is to use a very low cost (a fake or symbolic control) to gain user patience and satisfaction.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

In scenarios where users must wait or cannot truly control, provide a seemingly operable but low-risk control or feedback (e.g., pseudo progress bar, clickable 'refresh'). Ensure it gives at least immediate visual/tactile feedback to maintain a sense of control. Avoid making it promise unfulfillable results that turn into deception.
