Great thread here. When they first calculated the #sarscov2 death rate, @neil_ferguson and the other geniuses behind this mess didn't bother to consider they were using a sample totally unlike the average Wuhan resident.

And wait for the not-so-shock-twist about Neil at the end. https://twitter.com/GrahamNeary/status/1294645063985836032

Worse: it is not clear in the paper EVERY passenger on the six flights was tested. But if asymptomatic passengers were not routinely tested, the number of actual infections might have been FAR higher than the six they used to calculate the fatality rate...

And the gap would widen as the number of infected but asymptomatic passengers increased.

In other words, the less dangerous the virus, the further off their infection fatality estimates would be. (At this point, they appear to be off by a factor of 3 to 5.)
