Preponderance of Evidence
Updated 2026-08-10
INTRODUCTION
English translation pending.
CORE DEFINITION
A legal and practical threshold holding that a conclusion may be accepted when the evidence supporting it is more likely than not to be true, that is, above fifty percent. Its proposition is that different decisions warrant different evidentiary standards: criminal matters demand proof beyond reasonable doubt, while ordinary decisions can proceed on a preponderance. Qualifier: matching the threshold to the stakes is the whole discipline, since a uniform standard either paralyses small choices or recklessly rushes large ones.
SCAFFOLDING EFFECT
Reduce cognitive load
- Threshold calibration: Match the required strength of evidence to the cost of being wrong. - Everyday action: Proceed on a better-than-even case rather than waiting for certainty. - Paralysis prevention: Prevent perfectionism from indefinitely delaying decisions that are easily reversible.
Anchor fast decisions
Evidence standards function as decision thresholds, and each threshold trades error types against each other. A high bar reduces false acceptance but delays action; a low bar enables timely action but accepts more mistakes. Because delays and mistakes carry different costs depending on reversibility, calibrating the threshold to the decision is more rational than applying one standard everywhere.
