We've heard recently of HR departments saying that, because a study showed that sociopaths are (obviously) less likely to have Facebook accounts, people without Facebook accounts are bad hires. There is no personal data that corporate America will not find some way to use for evil.
Why wouldn't sociopaths have facebook? It's an excellent arena to play out little mind-games.
I don't doubt some HR departments would act on something like that, although they probably wouldn't stop hiring people that have a resume with strong leadership positions even though there are studies showing a correlation between attaining management positions and sociopathy...
