Although it is already being offered at 50% off, I feel so reluctant to put money in the pocket of Dr Birx that I will delay reading her new book until I see a remaindered copy on a charity bookstall.
Meanwhile, I recommend reading the whole of this and then also this (h/t instapundit) for some rather important information about the attitudes of one of the not-very-scientific science bureaucrats who brought lockdown to the USA. Here is a tiny sample.
No sooner had we convinced the Trump administration to implement our version of a two-week shutdown than I was trying to figure out how to extend it. Fifteen Days to Slow the Spread was a start, but I knew it would be just that. I didn’t have the numbers in front of me yet to make the case for extending it longer, but I had two weeks to get them. However hard it had been to get the fifteen-day shutdown approved, getting another one would be more difficult by many orders of magnitude.
Decide to lockdown first, find justification later. I resist the urge to add quote after quote; read the two complementary – but very uncomplimentary 
– reviews of her book at the links above!
In Britain, it was ‘three weeks to flatten the curve’, not two weeks, but in both countries somewhat reluctant chief executives were persuaded, against their instincts, to go along with it – and with extending it. (Both Trump and Boris would probably still be safely in office if they had refused.)
Birx wittingly and unwittingly reveals much. Boris will soon have some spare time for reflection and for writing another book. Will he – will anyone – tell us more about the Birxing of the UK?
