Naked lions are just as dangerous as elegantly dressed ones

I'm insatiably curious about human nature.

.. it makes sense that introverts are uniquely good at leading intiative-takers. Because of their inclination to listen to others and lack of interest in dominating social situations, introverts are more likely to hear and implement suggestions. Having benefited from the talents of their followers, they are then likely to motivate them to be even more proactive. Introverted leaders create a virtious circle of proactivity.

A widely held, but rarely articulated, belief in our society is that the ideal self is bold, alpha, gregarious. Introversion is viewed somewhere between disappointment and pathology.

You're told that you're in your head too much, a phrase that's often deployed against the quiet and cerebral. Or maybe there's another word for such people: thinkers.

In the first study, Grant and his colleagues analyzed data from one of the five biggest pizza chains in the United States. They discovered that the weekly profits of the stores managed by extroverts were 16 percent higher than the profits of those led by introverts—but only when the employees were passive types who tended to do their job without exercising initiative. Introverted leaders had the exact opposite results. When they worked with employees who actively tried to improve work procedures, their stores outperformed those led by extroverts by more than 14 percent.

The other thing Aron found about sensitive people is that sometimes they're highly empathic. It's as if they have thinner boundaries separating them from other people's emotions and from the tragedies and cruelties of the world. They tend to have unusually strong consciences. ... they're acutely aware of the consequences of a lapse in their own behavior.
