We know that this is an ISM and refers to to something that was invented by humans, and that's about as far as we've got. We do know that it doesn't begin or end with p, c, or anti. It has nothing to do with geography, geology, art, literature, or astronomy. It's not veganism, idealism, creationism, or dianetics, nor is it named after a person. There is a possible tenuous link to religion/spirituality, although all the guesses so far have not led anywhere. Normal people will think that the AOTC is crazy, those with more specialised knowledge will think that it doesn't work, although it still has its supporters.
