I'm not sure how you'd prove the theory that dinosaurs were cold-blooded, short of taking the rectal temp of a Stegosaur.
But you could falsify the theory by finding characteristics incompatible with being exothermic. Finding the dinosaurs with feathers and other characteristics of the (warm-blooded) birds probably helped, too.
Some of the "incorrect facts" are really theories that were substantiated to the best degree possible at the time, and no falsifying evidence existed at the time.
I suspect some, like "non-functional junk DNA", is a case of scientific qualifiers being ignored in the mainstream media and forgotten.
Humans like "facts", but we inevitably drop the error bars that originally accompanied each new "fact".
