porsche, nobody is saying that psychology or calculus cannot be used as a subject, nor that it cannot be used as a trasitive verb (read anon. more carefully). the debate is on the use of the word study.

as a translator, i would not feel happy using it this way in my translations, but i would not waste any time trying to tell people who do to knock it off, stop it, pack it in, give it a break, call it a day or the like.

it is unnerving for many to see language change, just as it is to see your children grow into adults. but attempts to prevent either are doomed to failure.
