"highly associated with what are known as the “dark” personality traits, which are also far more common in men ... narcissism (people who are grandiose, have a high opinion of themselves, react badly to insults)"
Really, any proof for that first claim? And was that last comment intended to be so ironic. Do men behave like  everybody else should be consumed with interest about what is happening in their personal lives or demanding special treatment? I'm sorry Margaret but IMHO the assertion that narcissism is associated more with men just defies all reason.
