CORE DEFINITION

Humans instinctively prefer curved and rounded objects (perceived as safe) over sharp, angular ones (perceived as threatening/warning).

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Emotional guidance. If you want users to feel relaxed and friendly (e.g., social apps), make buttons rounded; if you want users to feel alert and urgent (e.g., delete confirmation, error messages), make pop-ups square.

anchor

Anchor fast decisions

People tend to organize and remember shapes by closed contours, with edge information being more important than internal details. The mechanism is the Gestalt principle of closure: the brain automatically fills in gaps to form a whole.
