2. Without questioning whether these models and associated prescriptions were appropriate for developing country contexts, local experts borrowed and extrapolated these models. If the best health system in Europe could not handle the pandemic, the broken health care systems in developing countries would stand no chance. India and Africa would be swamped.
Social media and talking heads in television amplified and disseminated these doomsday prophecies. This is a representative sample of such alarming tales. Even the more perceptive experts who waste no time to caution against one-size-fits-all approaches in public policy began to sing from the same hymn sheet.
Nicholas Reich of the University of Massachusetts, Amherst, and his colleague Thomas McAndrew have used a questionnaire to ask a panel of experts on epidemics, including many who make models, how they expect the pandemic to evolve... Asked what they were basing their responses on, the experts said it was about one-third the results of specific models and about two-thirds experience and intuition. This offers a way to take the models seriously, but not literally, by systematically tapping the tacit knowledge of those who work with them. In studies run over the course of two flu seasons, such a panel of experts was consistently better at predicting what was coming over the next few weeks than the best computational models.
Plumbers have little to offer for real-time policy making but are good at post facto adjudication and castigation of government failures! This speech was an ad-hominem attack which mocked Kerala's health care officials, who today stands tallest fighting the pandemic.
epidemiologists are incentivised to exaggerate and always stress the worse-case scenarios rather than the better-case scenarios. experts and officials, in the advice they give govts, push worse-case scenarios and not better-case ones. The media picks this up and sensationalises the predictions. Public opinion whips itself into a frenzy. Consequently govts come under irresistible pressure to act on the worse-case basis. This gets further reinforced when all other govts act the same way. No govt or leader wants to act differently.Update 3 (09.04.2020)
Bibek Debroy urges caution on lockdown and argues against the panic reaction.
But “there are a lot of things that impact whether or not the test actually picks up the virus,” Priya Sampathkumar, an infectious diseases specialist at Mayo Clinic in Minnesota, told AFP. “It depends on how much virus the person is shedding (through sneezing, coughing and other bodily functions), how the test was collected and whether it was done appropriately by someone used to collecting these swabs, and then how long it sat in transport,” she said. The virus has only been spreading among humans for four months and therefore studies about test reliability are still considered preliminary. Early reports from China suggest its sensitivity, meaning how well it is able to return positive results when the virus is present, is somewhere around 60 to 70 percent. “In California, estimates say the rate of COVID-19 infection may exceed 50 percent by mid-May 2020,” she said. With 40 million people, “even if only one percent of the population was tested, 20,000 false-negative results would be expected.” This makes it critical for clinicians to base their diagnosis on more than just the test: they must also examine a patient’s symptoms, their potential exposure history, imaging and other lab work. Part of the problem lies in locating the virus as its area of highest concentration shifts within the body. The main nasal swab tests examine the nasopharynx, where the back of the nose meets the top of the throat. This requires a trained hand to perform and some portion of the false negatives arises from improper procedure. But even if done correctly, the swab may produce a false negative. That’s because as the disease progresses, the virus passes from the upper to the lower respiratory system.Update 4 (12.04.2020)
We can no longer go solely on the basis of international precedent. Nor can our sole consideration be to halt the pandemic, no matter the cost. India’s present lockdown has been rated as the severest in the world and the most disruptive by far, impacting a seventh of the world’s population. Whatever decision we take, we must keep foremost the impact of the lockdown on the poorest and the most vulnerable: For it is they who are likely to bear the brunt... While we know that the COVID pandemic is much more infectious and more virulent than the flu, it is also a widely accepted fact that viral epidemics abate only when around 60-80 per cent of the population acquires “herd-immunity” — either by vaccination or by acquiring the disease... It is incumbent that our experts and advisors present the decision-makers with the full facts, the latest knowledge and insights and a broader array of options rather than merely a single option; namely, to extend or not extend.Update 5 (26.04.2020)
Infectious respiratory diseases are a fact of nature. Beijing was finally driven to action by the same consideration that drove other countries to action—when the number of infected people and the duration of their cases overwhelmed a local hospital system. This is the proximate crisis that called for a public response around the world. Novel pandemic diseases are not a black swan. Our lockdown response was a black swan... "What happened? From Bill Gates to your local editorialist, a new priority waddled to the fore. We decided that, whatever contributes to killing Americans at a routine total rate of 8,000 or so a day, it shouldn’t be the coronavirus.
Update 6 (26.05.2020)Accidents, yes—6% of deaths. Heart disease, yes—23%. Flu and pneumonia, yes—20%.
These deaths are allowed but not deaths from the coronavirus even at the cost of economic ruin for millions. Of course the media and public are free to decide now they never wanted flatten the curve; they wanted to be spared the virus altogether. But explain how this is to be done. And explain why."
Ananth has a very good article in Swarajya on how a transnational technocratic elite has taken charge of Covid response policy across countries.
Yinon Weiss has a very good summary of how reliance on experts and groupthink contributed to the Covid 19 response.
