I played a small role in this that allowed me to see how these decisions were made. I think we should be honest at this point about how much of the policy was driven by vibes and politics. We had better data than people assume and it had almost no bearing on the decisions that were made.

Multiple governments had high-quality models that suggested a much lower IFR than what was widely reported, and in hindsight were proven correct. The news cycle was captured by people pushing doomsday scenarios and many people decided it was politically inconvenient to contradict that prevailing narrative. There weren't any complex motives, it was cowardice mixed with a bit of opportunism. I got to see this from the inside and I have no doubt that it would happen again, which gives me little confidence in the institutions.

There was an enormous amount of pressure to be seen to be doing something from the top in most countries, which led to a lot of the pointless theater that happened.

It is unfortunate but the poor reputation of public health officials due to COVID is well-deserved.
