Natural Experiment
Definition
A natural experiment examines differences caused by an external event.
An observational situation in which an external event or rule generates assignment to conditions without researchers controlling it; causal conclusions require credible, approximately random comparability.
Simply explained
A rule change creates comparison groups without researchers assigning them themselves.
Why it matters in practice
Helps realistically assess model quality, limits, and technical decisions.
Example from business
A regionally staggered rule change enables comparison of similar locations.
Limits and pitfalls
- Treat the assignment as randomized without verification or fail to investigate the assignment mechanism, confounders, and temporal changes.
Origin & history
Natural experiments are established in econometrics and epidemiology.
Use in mid-sized companies
- Possible application: A regionally phased policy change enables comparison of similar locations.
