I think that's an over reaction. Saying there's an error of +/- 3% is very different than saying we don't know anything, i.e an error of +/- 100%. With so many places and people reporting numbers there was always going to be some level of error. That doesn't mean the general message: cases are high and getting higher, hospitalizations are increasing, is in question.
Generally, most people don't have the default assumption that everything is a lie. Just because, theoretically someone could lie, isn't a reason to assume they are. I don't know how you'd live if everything had to be proven to you personally before you'd believe it.
True, and you'd know what would make a great, sensational headline? Hospitals/doctors/politicians lying about how many coronavirus cases and deaths occurred. I mean that Fox network just did it for a 3% max error. A willful 50% or more type error? That would drive massive viewership/clicks. That could win a journalism award! And yet, that size of error isn't being reported anywhere...maybe because errors on that size haven't been found...
I'm glad you are and I don't want to pick on you. It's just that I find the jump from "there's a margin of error in this data" to "we don't know anything!! a frustrating one. Because some people will think, "we don't really know what's happening so why should I inconvenience myself and wear a mask?" And that's a bad message to take.
In the end, whether there were 470 deaths yesterday or 449 deaths yesterday shouldn't really change the decision making of the average person. The numbers, as they are now, are good enough for decision making purposes.
