A few dissident scientists purport to be arguing for letting Covid-19 spread to produce herd immunity. Superficial news coverage makes it look like a serious scientific dispute, but their position is not clear enough to make sense. And its supposedly scientific supporters are not all real scientists.

In other fields, such "skepticism" has been funded by businesses with something to gain by creating a false impression of uncertainty. There is no shortage of businesses that might want to create the appearance of doubt about whether we should try to wipe out Covid-19. And there are rich supporters of the conman who might do this.

I wonder if someone who knows how to investigate could check for such connections.
