Platt's Strong Inference
Updated 2026-08-13
INTRODUCTION
English translation pending.
CORE DEFINITION
The fastest route to scientific progress, as argued by John Platt: formulate multiple competing hypotheses at once, design a crucial experiment that excludes at least one of them, and iterate the cycle. Rather than slowly accumulating supporting evidence, the method deliberately sets out to kill wrong hypotheses fast, so that resources concentrate on the survivors instead of being spread across explanations that were never going to hold.
SCAFFOLDING EFFECT
Reduce cognitive load
- Speeds killing over confirming: a decisive exclusion carries more information than another supporting fact - Focuses resources: attention concentrates on the hypotheses that survive each round - Structures the loop: hypothesis, exclusion experiment, and next round become a fixed cycle
Anchor fast decisions
Supporting evidence accumulates slowly and can be gathered indefinitely for a theory that is still wrong, because confirmation never exhausts the alternatives. A well-designed exclusion, by contrast, removes an entire hypothesis in a single step, which makes elimination the highest-information move available and rapidly narrows the surviving field.
