I have a hard time divorcing psionics from the sci-fi side of things, likely because it's based on the same root words as give us things like bionics or cryonic or cybernetics. The word itself evokes the idea of science, and particularly of artificially grafted (or possibly, evolved) powers.
Great post, but I think this is exactly what I mean
Psionics evokes the feel of science. It sounds like a science term, because it uses similiar language to science terms.
But, it is still just magic with a science coat of paint. In fact, I doubt you could find Psionics in a purely "Hard Sci-fi" setting, because we don't have the science to explain how it could really work.
You can create hard rules for it, just like you can have a hard magic system, but Psionics itself is not hard science (using literary terms)
