A new study on the habits of highly effective CEOs suggests that narcissistic personalities do better at bringing their companies into line with the latest innovations. The study measured how quickly different pharmaceutical companies adapted to the emerging biotechnology field that has risen over the last thirty years. They compared those measurements with the companies' CEOs, defining narcissism by the number of times they appeared in the press and the difference in compensation between the CEO and second in command.
I wasn't surprised to see this particulary common view that narcissists make good leaders, since there is 'healthy narcissism', but I was surprised to see the way in which they measured it.
