> Ioannidis says: “If we assume that case fatality rate among individuals infected by SARS-CoV-2 is 0.3% in the general population — a mid-range guess from my Diamond Princess analysis — and that 1% of the U.S. population gets infected (about 3.3 million people), this would translate to about 10,000 deaths.”
For anyone wondering, this quote is from [1] and doesn't appear in the linked article. I think the linked article is better worded and more nuanced.

I think comparing the measures that governments take with what effective entrepreneurs do is misleading for two reasons. First, for a country there is no single bottom line: a good balance has to be found between low mortality, good quality of life for those that do not die, and economy (which can be tied into the latter, or it can be independent if the government prioritises the wealth of a minority). Success of a company is mostly measured financially, or perhaps by visibility.
And second, the stakes are a lot higher for governments. They cannot fail and disappear if the measures are not a success. If they fail, human consequences are massive, but the country still exists. If entrepreneurs fail, the company might go into bankruptcy and disappear, but the impact is mostly financial. On the one hand this means that the risks can be acceptable if the consequences are only financial, and on the other hand this leads to a certain selection bias -- the successful entrepreneurs you see are ones that take risks and act decisively, and were lucky enough that their risks paid off.

- cycomanic 7y agoIn the article Ioannidis says: "The most valuable piece of information for answering those questions would be to know the current prevalence of the infection in a random sample of a population and to repeat this exercise at regular time intervals to estimate the incidence of new infections. Sadly, that’s information we don’t have." How does he know that this is not happening? It's been published for Sweden that they now moved to use "Sentinel tests" to track the spread of the virus (https://www.thelocal.se/20200320/fact-check-has-sweden-stopped-testing-people-for-the-coronavirus https://www.thelocal.se/20200320/fact-check-has-sweden-stopp...). This might explain the reason why the Swedish government is still quite relaxed. However, I would be very surprised if other governments would not be doing the same. Maybe this is the reason why governments really increased the response, because they are acting on this data. [edit typo]
