CORE DEFINITION

Berger and Calabrese proposed that the primary driving force in stranger interaction is to reduce uncertainty about the other person (both cognitive and behavioral), because uncertainty is unpleasant.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Ice-breaking logic. It explains why people engage in small talk, background checks, or stereotype categorization during first meetings. In product design (e.g., onboarding processes), the core is also to quickly reduce users' uncertainty anxiety.

Anchor fast decisions

At the beginning of interpersonal interaction, the other person is a 'black box'; unpredictability brings anxiety and interaction risk. Reducing uncertainty (through verbal exchange, passive observation, active questioning) enhances prediction and control, so it is an intrinsic motivation for interaction. Similarly, in product onboarding: new users face an unfamiliar interface full of uncertainty; providing quick guidance/feedback to reduce anxiety and establish predictability is a prerequisite for retention.

MINIMUM ACTION

In progress 0/5

Practice this model in one real situation:

Identify uncertainty: Where are users confused during interaction/onboarding?
Actively reduce: Use small talk/questions/guidance to reduce the other's uncertainty.
Provide framework: Offer predictable structures (processes/roles).
Feedback loop: Give users immediate predictable results for their actions.
Verify anxiety: Does interaction/retention increase as uncertainty decreases?
