I don't have time answer all of your points right now (I still have Billy's from the other day to do too) but let me just pick out a couple for now:
"The problem with using this as a hook to hang your covid response coat on to is if it's wrong you kill a lot of people.
there are scientists that we can quote who agree with your viewpoint and those that agree with my viewpoint, Which are right? I don't know, but as I have said many times, I would rather lock down and be wrong than keep everything open and be wrong."
So what do you do? Lockdown until? ..... when? You will still have a susceptible population. Would you lock down everytime we have a flu season? Serious question because we also have some severe flu seasons (we had overflowing on hospital trolleys in 2018). Would you want to "test test test"? If not why not? Track and Trace? Hmmmm, track and trace the flu....geezzz.
Could you give me one example (with data) where a lockdown has 'worked' (I realise there could be different definitions of "worked". so worked in your view)?
"I could, of course, counter your Sweden argument with Vietnam, Sri-Lanka or Singapore. They all locked down and did much better than most. I could also counter the Sweden comparison with the fact that the uk has 10 times the population density of Sweden."
Excellent...... Vietnam, Sri-Lanka, Singapore. What do all of those countries have in common? Location. I have a little digging to do in a book about seasonality so will come back with data about this, but you make an assumption, which is that Sars-CoV-2 (or coronavirus's in general) circulates in those South east asian countries. Big assumption, any data? I'm going to dig some out.
So we are saying that all the south east asian countries did track and trace superbly and eliminated the virus and all the northern european countries were all useless at it? Hmmmm, maybe, I don't yet have the evidence, but I suspect (I could be wrong) that coronavirus's don't circulate in that area all that much. That would have implications on track and trace. I have no evidence on this, purely a theory.
Track and trace in the UK was doomed to fail. The virus was established in the UK early this year, maybe even late last year. We had very limited testing in Jan (any?), Feb, March (not a criticism) and so the virus build up chains of transmission we were never going to be able to track realistically.
And population density, yeah, I thought the same..... denisty, more contacts, more interactions...... but you can't ignore the data (well, you seem to want to!).... the graph of Sweden and UK overlap excellently, no impact. It is the beauty of graphs, I have shown these to people at work and it really hits home. See my graph on the keir starmer thread (i think) comparing Brazil, Mexico, Peru. Peru (super harsh lockdown), Brazil (mixed) as Bolsonaro encouarged opening up...... result: Not a blind bit of difference, they overlap almost perfectly.(different shape to northern europe). It is so striking.
