I’m surprised that’s a hot take. It was the consensus on the sites I was visiting back when it was on the air.

The citation chain usually works like this:
-supposition stated as fact

-supposition with reference to reputable book from c.1930s

-reputable book from c.1930s with reference to Sir Edward Chortlemuffin, 1782

- Sir Edward Chortlemuffin, "here's an idea I'll fart out," 1782

So one of the things pll should be taught in grad school is that if you see the same supposition or phrase repeated in every publication on a topic, see if you can track it back to an antiquarian. Bc, more often than not, those guys were full of shit. Don't get caught out by the Chortlemuffin Effect
