:pointing out that every real scientist would sacrifice an

:and a silly machine that work just as well when you replaced the

John Campbell had a lot of fringe science interests, but I thought that
his involvement with L. Ron Hubbard's Dianetics ended when he became
disgusted with the way Hubbard was running the Dianetics organizations -
as his personal fiefs, with no others allowed to contribute to Dianetic 
research.  A recent biography of Hubbard quotes Campbell as saying that 
to the extent others can duplicate the results and perform useful research, 
that Dianetics would be a science; otherwise it would be a cult.

Did he later come up with specific disproofs of Dianetic theory?
