Great news!
Within a week, US death projections from
one of the models used widely (incl by White House) changed from 90k down to 80k and now to 60k.
Earlier range was 40k-180k. New range is 30k-120k.
This shows that stay-at-home measures, now applied to 97% of population, are working.
One explanation I read is that original models assumed 50% of people complied with stay-at-home orders and social distancing whereas in truth 90% do.
Let's keep pushing the projections down! Stay home and away from other people! You are literally saving lives when you do!
After reading your op I've decide that there must be a lucrative cottage industry in alarmist flip-flop rationalizing. Not 24 hours ago, when I posted that the pandemic would turn out no worse than a season of really bad flu, every kitchen sink within reach was tossed my way...so many it was impossible to answer them all.
None the less, the alarmists on the left echo'd the same thing: "it's all bunk, we don't know how many more have really died, you can't trust models, we don't know how many people are truly infected, the IHME model assumes 'full compliance' and we know many states are refusing to do that, 538 says the consensus is 250,000 something, yada...yada...yada".
NOW someone attempts to make lemonade out of a lemon, claiming not only that there has been full social distancing BUT that it was "super full distancing" so THAT explains why the IHME model turned to be correct...it's no longer unreliable, undercounted, bunk but testimony to the wisdom of our SD policies.
LOL... apparently hutzpah is a far more common than shame, and as some of the critics my charts beat a hasty retreat, it's worth revisiting and now adding to the errors of their partisanship.
First, the update note at the IHME DO NOT even discuss, let alone claim, that the revision downward is due to EXTRA social distancing. Furthermore it runs counter to the long-standing, left-wing, criticism that we were/are failing and not doing enough. Clearly somebody has some shame-faced explaining to do.
Second, at this time it is IMPOSSIBLE to know how effective formal state mandated social distancing is or how much credit should be given to it causing the failure of alarmist predictions. Predictions that were fundamentally histrionic a month ago were most likely were unsound and NEVER realistic.
Third, it is unknown what each kind of social distancing contributes (if any) to reduced numbers. For example, the Imperial college report said that mass gatherings of a few hours were not a problem, and also maintained that school closures only had marginal effects on mitigating virus spread.
Third, much is still unknown about this virus. We don't know it's natural infection rate (only a range of possibilities), it's natural mortality rate, or how much other factors affect it's expression; climate, UV exposure, population density, etc. However, what is clear is that population density is a critical element in its spread and perhaps lethality... the hot spots of NY and NJ suggest as much.
Four, it is also curious that OTHER urban areas are not virulent 'hot spots' : one hear's nothing about Chicago, Los Angles, Dallas, Denver, etc. It may well be that it takes very high population concentration's to maintain an epidemic - Louisiana, for example, was feared to become unmanageable but in spite of some stubborn resistance to formal and full SD measures, they already turned the corner and hospital capacity is not a concern.
Five, it is also impossible to know whether formal SD policy made a difference compared to what people do anyway, voluntarily. It may well be that formal shutdowns accomplished much less than people, on their own using common sense, made in selectively choosing when and how to expose themselves (which, by the way, is what the OP implies).
In sum, there is no reason to maintain that only formal, government mandated social distancing could or even did lower the last two iterations of the IHME forecast, anymore than there is a reason to assume that government subsidies and limits on crop production save us from starvation.
But you could have tracked the data, without knowing the mechanisms, to predict when and how this will end - in other words, look at the charts.
