I feel like fluff articles like this are written by people who have never actually been in the situation they write about.

One of the first things one learns when working professionally is to say “I’ll look into that and get back to you” or some such instead of “I don’t know” and just standing there.

I say "I don't know" when I'm reasonably confident that the other guy doesn't know, and that neither of us is going to look into it. It's sort of like "next question."
