Are narcissists born or made? And are there more of them than ever before? This week we revisit narcissism: what causes it and when it verges into a serious disorder. Narcissists have an inflated sense of self, a lack of empathy and can be vain and materialistic. And they can be incredibly destructive to those around them. Earlier this year, Insight brought together psychiatrists, workplace psychologists and parents to discuss whether narcissists are born or made. In this week’s replay, we look at the whole spectrum – from those obsessed with their Facebook pages, to those whose lives have been torn apart by narcissists.
