The wikipedia page say "Degrees in psephology are not offered (instead, a psephologist might have a degree in political science and/or statistics). " which I know. The issue is that there does not really seem to be much of a world community for this stuff. It seems like a real subject of academic study but it is almost impossible to find an academic who studies this. There are a number of academics, like myself, who do it as a hobby. Is there no academic journal for the work? It seems reddit is where the action happens which is very weird.
Some of the lest informed academics who claim expertise are actually the political scientist who have to teach a few lectures on this and learn for that. In my experience they do not have the math background to really understand the topic but think they understand the whole topic. Is the lack of academic pushback the real reason that groups like FairVote manage to get away with what they do? In most scientific fields, the experts will put people in their place if they start spreading propaganda.
