Why is recruiting volunteers on Facebook less random than any other form of recruiting?
I read articles evaluating the reports and suggesting where they might be wrong, but I didn’t see any saying the tests might detect other kinds of viruses. One said that the only thing the researchers found when verifying the results is that they might get false positives, not false negatives.
Because there’s “random” which is required, pretty much, for good “Science” and then there’s bias, like recruiting on Facebook.
