There needs to be a logically-valid reason to bring gender/age/country of origin/etc. into the discussion at all.

I.e., if you're interviewing an individual for a job, that means you're evaluating that individual's ability to fulfill the job requirements.

You'll get a hell of a lot better mileage out of, say, talking to them about complicated problems than you could ever get from even the average IQ in their family, let alone country or some other ridiculously large group like that. No need to get into the discussion of how valid that number is -- it's irrelevant to a job interview.

To the original point -- if maybe some large-scale study does show that young women tend to make more "social noise" than young men, I'm still having trouble imagining ways that might be relevant when noisy people enter a room I'm in.
