The frequent crank fallacy of the appeal to Semmelweis

A proponent of the Great Barrington Declaration is comparing rejection of its “natural herd immunity” approach to the pandemic to the rejection of Ignaz Semmelweis and his findings (and Galileo, too). It’s a deceptive comparison beloved of all manner of scientific cranks.

The Galileo Gambit: Just because your quackery is rejected by the establishment does not make you Galileo or Semmelweis

Quacks love to invoke experts who made predictions that turned out to be wrong or point to Galileo or Semmelweis as examples of scientists whose findings were rejected by the scientific or medical establishment of the time, as though poor prediction or rejection by the establishment means there must be something to their science. Guess what? As Michael Shermer put it, heresy does not equal correctness.
