You’re still missing my point.
No, I disagree with your point.
Frequently the science that is used to support a particular medication, procedure, or product is crap
Let's be clear. Science is a constant. It never changes.
Our understanding of science is a rollercoaster. It always has been and always will be.
We observe. We hypothesize. We test. We keep repeating until we get it right. Mistakes are a huge part of the process. No one wants to make mistakes, but Murphy is an a-hole. Mistakes happen and are mostly unavoidable. Like rain, you can hate it, rail against it, and yell at the meteorologist when it ruins your parade. It's still going to rain. We observe our mistakes. We modify our hypothesis. We keep testing. Science never changes, but hopefully our understanding will more closely align with actual science. Yes, it's frustrating because it seems we take two steps forward and one step back. Progress is often painful.
Arthroscopic procedures on knee meniscus is also often advocated for by orthopedics in spite of evidence that for the average person they have no benefit.
My partial meniscectomy was an absolute success. That was 40 years or so ago. So were all the wrist and hand surgeries, the rotator cuff, the plates to fix my broken leg, the initial back surgery and I know I'm forgetting some.
Of all the procedures and surgeries I've had, only the PPP and my heart cath were a bust. There were some benefits to the ppp, in that it resolved a deviated septum and got rid of my tonsils. I used to get all sorts of respiratory infections, but those are now history. The heart cath was indeed needless. Other than losing my high tenor, I suffer no long-lasting side effects from either of those procedures. Medical science will continue to evolve. I'm fine with that. If you don't like the current results, don't yell at the researchers. Get off your butt and make a difference, instead. Do some real research in a lab. Yes, it will take time, money and resolve.
Me? I trust in the Hippocratic oath. Doctors spend their lives learning to cure what ails us. The CDC has more resources and is collectively smarter than all the 'experts' on the internet. I'm working through back issues at the moment. At my last procedure, the Doc was completely candid. He said they were guessing. There's no way they can know for sure which nerve is causing my pain. It's obvious that they need to try another area. There's a bit of relief, but I still have quite a bit of pain. I still trust the process of elimination here, as frustrating as it might be. Why? There is no other process. It's the best we have at the moment. Getting mad and casting aspersions at the doctors' genealogy won't make it any better. There aren't any conspiracies here. There are only successes and mistakes. There are misunderstandings as well as breakthroughs. But science remains constant. We just need a better understanding of it. Time, patience, and resources will help us in that endeavor.
Caveat: some drug companies put profits ahead of cures. These are outliers, even though they consume more than their share of media coverage. The vast majority of scientists and doctors want to make things better.
