Experimental Design
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
By designing controlled experiments to test hypotheses: - Clarify the hypothesis - Manipulate the independent variable - Control extraneous variables - Measure the dependent variable - Analyze results Transform "I think" into "data shows." Scaffolding role: Let reality adjudicate disputes. When facing uncertainty, rather than debating whose viewpoint is correct, design an experiment to let facts speak. This is the core of the scientific method and also applies to business decisions.
SCAFFOLDING EFFECT
Reduce cognitive load
Let reality adjudicate disputes. When facing uncertainty, rather than debating whose viewpoint is correct, design an experiment to let facts speak. This is the core of the scientific method and also applies to business decisions.
Anchor fast decisions
By manipulating the independent variable, controlling extraneous variables, and measuring the dependent variable, transform "I think" into "data shows," letting reality adjudicate disputes. Randomization and control eliminate confounding, making causal inference more reliable; this is the core of the scientific method and also applies to business decisions.
