“Nobody knows the truth — let’s be honest,” Dr. Ioannidis said of the prevalence figures. “But if I had to guess, I would say it is probably higher than our estimate.”

“It’s not perfect, but it’s the best science can do,” said Dr. Ioannidis. https://twitter.com/nytimes/status/1252940247408816128

To be clear, I don't think the true prevalence is higher than their estimate. And is a volunteer-driven serosurvey using a test with poorly characterized specificity the best science can do?

Also, shout-out to @nytimes for getting quotes from two co-authors of this not yet peer-reviewed study but none of the people who have pointed out its problems.
