Another concern with approving drugs more easily: you might then never find out if they really work or not.<p>The reason we need very large, expensive, and strict clinical trials is because it&#x27;s hard to see if a drug actually works or not otherwise - too many confounders. So if we pass drugs through with a higher error rate, we&#x27;ll likely never know if some of them actually work or not. Maybe not a problem for a disease with no treatment at all, but imagine you have 10 treatments and you suspect that 7 of them don&#x27;t actually work, but you don&#x27;t know which 7. Is that better than just having 3 available treatments where only 1 of them doesn&#x27;t actually work?
