I can’t vouch for the methodology here; I’m sharing for interest. To be honest I’m sceptical about evidence about effectiveness of lockdown in general – it’s going to be tough to figure out and may require a lengthy progress. Anyway, I do predict we will see more of these kinds of claims, and even if they are flimsy, so, to be frank, are many of the claims made about locking down. Perhaps the most interesting thing going on right now is that there a change in what seems obvious. Things that formerly spoke for themselves no longer do. From the perspective of someone who thinks about science, that is fascinating. It’s part of what Kuhn called paradigm shift.
