Whitty is an interesting one. It’s easy to forget how very early on in the pandemic he was actually the voice of reason. When the media decided that herd immunity was tantamount to murder, and it became clear that “follow the science” really meant “blame the scientists” he suddenly changed his tune, perhaps understandably.
"Follow the science" was unhelpful from the start, it's a sound bite that falls apart very quickly under further inspection. There were occurrences during the various briefings where Whitty referenced the deaths society would accept during a bad flu year and the need to decide what is acceptable for covid.
Was it reasonable though? And was it spelt out clearly that it was worst case? Ferguson has a credibility problem in my opinion; this isn’t the first time his modelling has been called into question.
That said, presuming the politicians and their advisors were presented with all of the scenarios, they are ultimately responsible for the (poor) decisions made.
In the BBC article it is clear that it was stated as the worst case. The modelling closer to the first lockdown (from what I remember) had smaller death figures, to me it seems unlikely the decisions would have been so late if it was smaller than what they already expected. The source document with the scenario clearly states it's a reasonable worst case and a long paragraph about what that means, why it's unlikely to happen, why it's sensible to plan for.
Reasonableness is subjective and people will have different opinions. There aren't many large scale pandemics in humans, taking the highest clinical attack rate and fatality rate of those together seems a good starting point. (Mutations tend to make more infectious, less lethal but that doesn't apply to the first wildtype). The small margin on top of the fatality rate is more debatable but didn't make much difference to the total. It's not something crazy like assuming a very lethal virus would spread or that avian flu would be as successful in humans.
Ferguson isn't perfect, but some of those calling him into question haven't shone either. The spectator article that stripped the lower half of all the confidence intervals and compared the outcome to the number that is expected to be above the actual 97.5% of the time was either dishonest or poorly researched. Particularly the case where Ferguson stated to the BBC at the time of the model that the most likely outcome would be towards the lower end and the top was a long tail.
I agree to an extent. However, this doesn’t explain why we threw away decades of pandemic planning and decided to implement a lock down. I actually don’t think there was much science involved; there was however weak (read non-existent) leadership, buck passing and dogma in abundance.
Part of the issue is that local pandemic planning was for a number several times smaller than the reasonable worst case (mostly due to cost). Coupled with a healthcare system struggling with a normal year, personally I suspect there was an eventual realisation that the plans weren't workable.
Again, I agree to an extent. I’m slightly forgiving of the first lockdown for this reason, notwithstanding the point I made above in regard to established pandemic protocol.
However, by the time the second lockdown was implemented this no longer applied; we knew enough by that point. Then of course there was the third, which was (and is) completely inexplicable and indefensible in my opinion.
Yes, there was time by that point for a different approach to be tried. Some of the more alternative voices weren't helpful, e.g. trying to push PCR false positive narratives to say nothing required than urging focus on how to deal with the next potential peak. There would also have been political resistance to a different approach including some of SAGEs suggestions that didn't involve widespread restrictions.
I suspect there is an element of re-writing history going on here, I don't recall all the models being presented at the time as being only worst case scenario. I seem to recall at least one model was actually presented at the time as the best case scenario, yet was still far worse than anything that actually happened.
If it were true that only the most extreme worst case scanarios were ever modelled then there would be serious questions to ask about why public policy was based only on extreme worse case scanarios with no more realistic possibilities being investigated.
No where near all models were presented to the public. In some ways the transparency of the modelling was part of the problem, various media outlets just used the visually appealing graphs into stories rather than focusing on making it clear what the models covered, their limitations and guidance on interpretation. In some cases the most optimistic scenario modelled was careless morphed into the 'best case' in the media stories which is a very different thing, the everything goes down and you don't need to do anything scenario is rarely included as the decision is obvious and the time to create/typeset/proof it is wasted.
