"Ask someone with low self confidence to stand next to a white board and "implement" solutions to random problems, and he/she will freak out. At the same time, these people might very well excel in a more nurturing, friendly environment."

I don't think a company interviewing a candidate needs to be holding their hand during the interview process. I understand that someone might perform a lot worse when whiteboarding, but an interviewer should be taking that into account.
