Ioannidis predicted 10,000 deaths tops in the US based on no restrictions. To say he’s “by no means infallible” is extremely kind. It would be akin to saying that people who believe in flat earth theory have “unconventional” or “maverick” opinions.
And as for your assertion of “more right than wrong”, I’d say that somebody who predicted 10,000 deaths in the US based on a no restriction environment has got it so spectacularly wrong that they have pretty much lost the right to be taken seriously on anything ever again.
