INTRODUCTION

English translation pending.

CORE DEFINITION

Proposed by Karl Popper in Logik der Forschung, translated as The Logic of Scientific Discovery. Popper argued that no finite set of observations can verify a universal law, since the next case may differ, but a single counterexample can refute it. Science therefore advances by conjecture and refutation: bold hypotheses are proposed and then subjected to tests designed to break them. Falsifiability is a criterion of demarcation between empirical science and non-science rather than a theory of meaning, and it demands only that a refuting observation be conceivable, not that it ever occur.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Claim triage: Ask what observation would count against the claim before weighing evidence for it. - Test design: Build the experiment that could break your hypothesis rather than the one that flatters it. - Pseudoscience alarm: Treat theories that explain every possible outcome as unfalsifiable.

Anchor fast decisions

Universal statements range over unbounded cases, so evidence can never exhaust them, while a single contrary instance contradicts the universal. The asymmetry between confirmation and refutation is what makes testing informative: a passed test eliminates some possibilities, whereas support merely leaves the hypothesis standing. Theories that can accommodate any result are never eliminated, so they carry no empirical content about what will happen, which is why Popper places them outside science.

Mediocrity Principle

A heuristic against assuming special status without contrary evidence; typicality depends on the reference class and sampling process.

Unknown Unknowns

Knowledge gaps or uncertainties not yet recognized as such; the terminology predates Rumsfeld’s prominent 2002 remarks.

Grey Swan

Refers to events that have a very low probability of occurrence, but if they occur, have a huge impact, and to some extent are foreseeable (not completely unpredictable, i.e., not black swans).
