Doesn't bother me in the slightest. In fact, I almost included another parenthetical:

(Hard scientists probably do think hard is good and soft is bad, but that's because they're hard scientists. Soft scientists are probably sensitive to the negative connotations the hard scientists attach to these terms, because there is something of a rivalry between hard and soft science.)

I guess you've studied some kind of soft science at a college or university?

(I feel like I have overused the terms, though. I make sound as if there is a strict divide, when in my mind it's an evenly distributed spectrum.)
