Popper's Falsifiability
Updated 2026-08-08
INTRODUCTION
English translation pending.
CORE DEFINITION
Proposed by Karl Popper as the criterion for demarcating science from pseudoscience, most fully in The Logic of Scientific Discovery. A theory is scientific if it forbids certain observable outcomes; if no conceivable observation could refute it, it lacks scientific status. Popper argued that induction cannot confirm theories, so a theory is only ever accepted provisionally, having survived severe attempts at refutation.
SCAFFOLDING EFFECT
Reduce cognitive load
- Test the claim: ask what observable outcome would show this to be wrong - Filter the unfalsifiable: set aside claims that no evidence could contradict, whatever their appeal - Design refutation: look for the test most likely to break your own view rather than collecting support
Anchor fast decisions
A claim that excludes no possible observation is compatible with every state of the world, so no evidence can bear on it. Science progresses by making risky predictions that rule out alternatives, then exposing them to tests. When a prediction survives a severe test, confidence rises not because the theory was proven but because the plausible ways it could have failed did not occur.
