Larry Niven had a fixed idea about cetacean intelligence, and it showed up in mass-audience SF like Star Trek IV.

The story below is another example of really creepy things being done in the name of science in the postwar era.

Yud once debated Massimo Pigliucci and did poorly. He tried and failed to publish academic research in a journal not controlled by his groupies (desk reject? failed to pass peer review?).

Have there been any other times when he engaged with someone with actual education and experience who was not his fan? It sounds like he was on twitter.
