There are tons of cranks, certainly, but itโs a nice little racket that academia has going that you get much credibility from merely being in academia, and if you arenโt in academia no amount of being right proves anything. It was all โjust chanceโ or you didnโt have the proper credentialsโฆeven though you were correct and those in academia were not.
These types say that if you had the right credentials youโd be taken seriously. However, having the right credentials in too many areas means that youโd have to be stylishly wrong to be given any credence.
I donโt even care that much. Iโd rather be right. But itโs all sclerotic and doomed as it wonโt be able to self-perpetuate for much longer.
