We all know a narcissist or two — the often-annoying colleagues, friends, and family members who seem to be constantly talking about themselves and touting their own achievements. In some ways, these characters are a paradox. They seem to be in love with themselves — and when they’re asked in questionnaires, they claim to have very high self-esteem — but their behavior poses an obvious question: If you were genuinely happy with yourself, why would you feel the need to constantly boast and seek admiration from others?
A new study in Social Cognitive and Affective Neuroscience potentially solves the mystery: Narcissists may talk and act confident, but their brains don’t lie. At a neural level, narcissists are needy.
