They have a high false negative result, so pretty much useless

whoops, meant false positives.

Yes. You make a good point.

I am a biochemist, and Fuellmich DOES make a lot of sense.

The only thing he seems not to fully understand is that a biological method of analysis (specifically, the PCR test for COVID-19) can be set up to maximize sensitivity (i.e., to detect as many positive cases as possible), OR it can be set up to maximize specificity (i.e., to avoid as many false positives as possible). But one cannot simultaneously maximize BOTH sensitivity AND specificity.

So, a sensitive PCR test is NOT some kind of evil plot: its high false positive rate is inevitable for a maximally sensitive test.
