“You don’t have to be a total narcissist to be a successful executive – but a solid dash of ego can help,” Rachel Feintzeig, a management reporter for the Wall Street Journal, writes in WSJ’s At Work blog. And she’s right. Citing sources from the University of Illinois at Urbana-Champaign, the University of Nebraska at Lincoln and Hogan Assessments, she delves into the controversial topic of narcissism in the workplace. Hogan’s managing partner Rodney Warrenfeltz discusses the implications of Bold scores in the 70-90 range and above on the Hogan Development Survey. Despite its stigma, narcissism and “being able to influence people is a crucial part of effective leadership” writes Feintzeig.
