Not if the signal is strong. Whether a thing works or not, is a pretty strong signal. Your equating it to bad effects of smoking is flawed and is not comparable.
You other arugments are also pretty bizzare, but not going into that for sake of focus.
> if the signal is strong, it will be visible
> your specific example of it taking decades of massive deployment and close scrutiny to detect an effect significantly stronger than most drugs is ummm... flawed and not comparable for no reason I can articulate
okay buddy
That's okay, you're someone who thinks the FDA is in cahoots with insurers and drug companies to approve ineffective or unsafe drugs at scale lmao. And here you are arguing that the market would actually naturally detect exactly that.
What the heck are you smokin? Did paracetamol have a weaker affect on temperature than smoking causing cancer?
Thank you for demonstrating my point.
