An argument for *random* COVID-19 testing. Tesing is biased toward the sick & ill. So we don't know how much COVID-19 there is or how dangerous it is. This uncertainty => over and/or under reaction. We can't manage what we don't measure respresentatively. https://www.statnews.com/2020/03/17/a-fiasco-in-the-making-as-the-coronavirus-pandemic-takes-hold-we-are-making-decisions-without-reliable-data/ …

Totally random sampling makes no sense as we want probability sampling to favor finding positive cases. But the current approach doesn't give us statistical knowledge. I'm not an epidemiologist (don't know the field also see ethics thread) but current test frame teaches us little

I don't think that's true - it teaches us a lot. What it doesn't give us is perfect information, but I think the reality is that we simply aren't going to have perfect information for some time yet
