All-or-None Law
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
When a neuron is stimulated, it either does not respond at all or produces a full-strength action potential. There is no such thing as a "half" action potential. Stimulus intensity only affects the frequency of firing, not the amplitude of a single impulse.
SCAFFOLDING EFFECT
Reduce cognitive load
A digital decision threshold. When making key decisions (such as starting a business or getting married), do not pursue "half-hearted attempts." Either do not do it, or commit fully (full strength). Ambiguity in attitude (analog signal) will attenuate during execution; only decisiveness (digital signal) can maintain fidelity in a long chain.
Anchor fast decisions
Neurons fire all-or-none: if the threshold is reached, a full-strength action potential is generated; if not, none occurs. Intensity is encoded by firing frequency rather than single amplitude. Metaphor: key decisions should be "digital" (decisive) rather than vaguely analog.
