CORE DEFINITION

In multiplication, no matter how large the other numbers are, if one factor is zero, the result is zero. In systems, this refers to certain key elements (such as integrity, safety, health) having a "veto power."

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Identify fatal shortcomings. It reminds us that some shortcomings cannot be compensated by strengths (e.g., if health is zero, career success is also zero). In system design and personal development, it is essential to ensure these "zero multipliers" are not zero.

Anchor fast decisions

In multiplication, any factor being zero makes the result zero—in systems, certain elements have "veto power." The mechanism is "fatal shortcoming"—overall effectiveness does not depend on the longest board, but is limited to zero by the most critical zero multiplier, and long boards cannot compensate.
