The Uncertainty Principle: How to Make Policy When We Don't Know Everything
Nicotine policy is made under uncertainty—the long-term effects of reduced-risk products are not fully known. The uncertainty principle: we must act despite uncertainty, and the appropriate response to uncertainty is risk management, not paralysis.
We don't have 30-year data on vaping. We do have 15-year data, mechanistic evidence, biomarker studies, and population-level outcomes from countries that have embraced harm reduction. **The precautionary principle says: don't act until you're certain. The uncertainty principle says: act on the best available evidence, acknowledge what you don't know, and adjust as you learn. The precautionary approach protects against one kind of error (acting too soon). The uncertainty approach protects against another (acting too late).**
