I don’t know very enough about clinical psychology to say anything intelligent or technical about this, but I’ve always felt that we are now essentially ruled by people with severe personality disorders. This study might help explain why:
Narcissists are not necessarily more creative than their peers, but they think they are, and they are adept at convincing others to share their inflated view of themselves, says Jack Goncalo, assistant professor in the department of organizational behavior at Cornell University.
Three studies led by Goncalo in 2007 and 2008 showed that narcissistic individuals asked to pitch creative ideas to a target person were judged by the targets as being more creative than others.
New research finds that narcissists are able to influence creativity in groups and in the workplace because they convey more enthusiasm, confidence, and charisma while they are selling their ideas to others.
[…..]“The danger is that the ideas suggested by narcissists might actually be implemented despite the fact that they are not necessarily very good,” Goncalo says.
