CORE DEFINITION

Having two watches that show different times makes it impossible to know the correct time. This metaphor illustrates that facing two or more conflicting standards leads to bewilderment.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Conflicting standards cause confusion; a unified action principle is necessary.

anchor

Anchor fast decisions

When a person wears two watches that show different times, they cannot determine the correct time—having two conflicting standards/authorities leads to chaos and loss of trust in standards. It illustrates that if goals, instructions, or evaluation systems are contradictory (e.g., multiple bosses, conflicting KPIs), organizations and individuals will be at a loss.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

Identify whether there are 'two watches' in the system (conflicting goals, bosses, metrics). Choose one authority/standard as the primary clock, and demote or align the others. Merge or clarify multiple instructions to ensure goal consistency. Give subordinates only one clear, non-contradictory evaluation. Regularly review whether the standard remains singular.
