Actually, I think studies purporting to prove psychic abilities are real is something that students should spend time on. Remember this article?

I skimmed the study in question. There are no obvious methodological flaws, and by the standards of psychological publishing, it was worthy of publication. It's my opinion that ALL students of psychology should read it critically, and understand why it doesn't prove that psychic abilities are real. (Then they should apply that same skepticism to the rest of psychology research.) It's a great exercise, just like doing easy integrals, or spotting flaws in proofs that 1 == 2.
I do agree that we should study how poor science is done. But there's a difference between studying poor science, and actually spending time trying to figure out how one might actually be the next Airbender.
Lack of discussion is never a good sign.
At what point do we say, that point of view has so little evidence that hearing it is a waste of time, given time is a limited resource?
