There is an entire branch of study - one which I work in - whose entire job is to run either observational studies or post-hoc studies using real world data to find out if something had an impact, a positive impact, negative impact, and what the likelyhood of your own study being correct is.
If you think this is 'done' and we shouldn't revisit this to see what we did well / did poorly then that is as anti-science as they come.
You are lumping every response to the pandemic together and appear to be saying "you can't judge this, would you rather millions have died??" - well no, but thats not the question either. Instead "We did things to respond to the pandemic, some good some bad. What was good and what was bad."
This will happen. Saying "NO NO NO" is not going to stop that or help it.
No!
We already know we made the right choice because the alternative was 20 million more dead. This "time will tell" bullshit is ridiculous. We swerved the car to avoid crashing it head on into a wall, and yes you might have whiplash but there is no honest room for second guessing the decision not to drive the car into the wall at full speed.
