Peter Navarro, an advisor to President Trump, made the news today by shouting at Dr. Anthony Fauci, the leading American expert on infectious diseases, about a drug that Trump thinks (without any scientific evidence) should be used to treat COVID-19.

Navarro is described on his Wikipedia page as a retired “professor of economics and public policy. . . . Navarro’s views on trade are significantly outside the mainstream of economic thought, and are widely considered fringe and misguided by other economists.”

Very few social scientists, of course, would join Navarro in claiming they should advise Dr. Fauci on the best way to treat COVID-19.
