from Walter Williams:
FDA Policies Kill
Among the U.S. Food and Drug Administration’s responsibilities are approval and regulation of pharmaceutical drugs. In short, its responsibility is to ensure the safety and effectiveness of drugs. In the performance of this task, FDA officials can make two types of errors — statistically known as the type I error and type II error. With respect to the FDA, a type I error is the rejection or delayed approval of a drug that is safe and effective — erring on the side of over-caution — and a type II error is the approval of a drug that has unanticipated dangerous side effects, or erring on the side of under-caution.
Let’s examine the incentives of FDA officials. If FDA officials err on the side of under-caution and approve a drug that has unanticipated dangerous side effects, the victims of their mistake will be highly visible. There may be congressional hearings, embarrassment to the agency and officials fired.
It’s an entirely different story if FDA officials err on the side of over-caution and either disapprove or delay the approval of a drug that is both safe and effective. In that case, the victims will be invisible. They will have no idea that their suffering could have been eliminated, or in the case of death, their loved ones will have no idea why they died. Their suffering and/or death will be chalked up to the state of medicine rather than the status of an FDA drug application. Their doctor will simply tell them there’s nothing more that can be done to help them. The FDA officials go scot-free.
