Want to lead? Employ some Machiavellianism
The Association for Psychological Science published and interesting article on a recent study which looked at so called "Dark Triad traits" (namely psychopathy, narcissism, and Machiavellianism) and rates of corporate success.
They found that individuals with higher tendencies toward narcissism tended to be better negotiators and had higher salaries, while the Machiavellianists tended to enjoy positions of leadership. Most psychopaths didn't do too well because they tend to be unable to work with others.
Not only did the article make me wonder how I would fare on a test used to detect these traits, it also caused me to look suspiciously at the leaders around me... ;-)
