Mmm. The trouble with that and with REVERSE/OBVERSE is that it isn't immediately clear which one is positive and which negative. Same with DROITE/GAUCHE, come to think of it.
(Hmm, although POSITIVE and NEGATIVE do qualify on that basis. Bit long, though, unfortunately.)
RIGHT/WRONG is quite nice, though, and surprisingly semantically close to the usual choice in practice of TRUE/FALSE. I wonder why nobody uses it. I suppose there's a bit of a connotation shift: FALSE means you've just made a statement (for whatever reason) that isn't true, whereas WRONG means you genuinely thought it was true and are actually probably-culpably mistaken. Hmm.
