Iron Law of Prohibition
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
The more stringent the prohibition on a substance (such as alcohol or drugs), the higher the potency/purity of that substance. Because smaller volumes are easier to conceal, smugglers prioritize transporting high-purity drugs (e.g., heroin instead of opium), leading to increased harm.
SCAFFOLDING EFFECT
Reduce cognitive load
Analysis of side effects of regulation. In corporate management, if you strictly prohibit a certain channel (e.g., forbidding bypassing the chain of command), employees may achieve their goals through more covert and destructive means (e.g., anonymous complaints, external leaks).
Anchor fast decisions
The Iron Law of Prohibition (Cowan's iron law) states: the stricter the enforcement against prohibited goods, the more the forms circulating in the black market evolve toward high-concentration, high-potency variants (because they are easier to conceal and transport), and the prohibition ironically escalates the intensity of harm.
