::::: Your first link is the only arguable one.  The second link is a straight copy of some revision of this article.  The third link only refers to PK in terms of a spoon bending book, and spoon bending is specifically addressed in this article (yet not in the mentalism article). The book in the first link makes it clear that there is a difference between PK and the illusion of PK; They call it "PK-magic" or "PK effects".  Other uses of the term are within that specific context.  So I still don't think there is any reason to believe the difference between PK and mentalism as terms are in any way ambiguous.  Think of it this way, flying is a regular phenomena.  Copperfield flies in one of his illusions.  The act is refered to as "flying".  But no one would argue for a disambiguation notice on Flight_(disambiguation) saying "for the illusion of flying, see Magic (illusion)". But no matter, I think 5Q5's solution is a good one. -
