Points 2 and 3 are HN responses to my comments or adjacent ones. It's going to be a bit hard to find them now, but I'll post them at the bottom. Listen, I really don't want to Gish Gallop you, but there's no way for me to claim people were saying this without showing you people saying this: (and there are way more people saying this on Reddit and Twitter, but time is short, so I can't do any more research for you)
Ah, I misread your original post. I thought you were talking about the official recommendations being wrong and then changing. The "general public shouldn't wear masks" is one example where the guidance changed, but I'd argue that overall it's been relatively consistent.
If you are just looking for random people on the Internet being wrong, then yes, there are lots of examples of that!
Well, it started with the officials because let's just say we're not working with very good raw material here. It's like the tar sands, you know. We have the tar sands, some other guys have shale, and some others have some delicious light crude.
I agree 100%. The US's response to this entire pandemic was, and still is, a cluster fsck. A lot misinformation could have been prevented with strong and consistent leadership.
