Why Central Planning by Medical Experts Will Lead to Disaster
A great deal of the coverage of the COVID-19 crisis has been apocalyptic. That is partly because “if it bleeds, it leads.” But it is also because some of the medical experts with media megaphones have put forward potentially catastrophic scenarios and drastic plans to deal with them, reinforced by assertions that the rest of us should “listen to the experts,” because only they know enough to determine policy. Unfortunately, those experts don’t know enough to determine appropriate policies.
Doctors, infectious disease specialists, epidemiologists, etc. know more things about diseases, their courses, what increases or decreases their rate of spread, and so on than most. But the most crucial of that information has been browbeaten into the rest of us by now. Limited and imperfect testing also means that the available statistics may be very misleading (e.g., is an uptick in reported cases real or the result of an increasing rate of, or more accuracy in, testing, which is crucial to determining the likely future course COVID-19?). Further, to the extent that the virus’s characteristics are unique, no one knows exactly what will happen. All of that makes “shut up and listen” advice less compelling.
More important, however, may be that in making recommendations to address COVID-19, those with detailed knowledge of the disease (the experts we have been told to obey) do not have sufficient knowledge of the consequences of their “solutions” for the economy and society to know what the costs will be. That means that they don’t know enough to accurately compare the benefits to the costs. In particular, because of their relative unawareness of the many margins at which effects will be felt, the medical experts we are being told to follow will likely underestimate those costs. When combined with their natural desire to solve the medical problem, however severe it might get, this can lead to overly draconian proposals.
This issue has been brought to the fore by the increasing number of people who have begun questioning the likelihood of the apocalyptic scenarios driving the “OMG! We need to do everything that might help” tweetstorms, on the one hand, and those who are emphasizing that “shutting down the economy” is far more costly than planners recognized, on the other.
