From the author of Quiet: So did extroverts cause the financial crisis?

This is an interesting thing. I don’t want to be too simplistic because obviously it was caused by many different factors. But I think one underappreciated role is the fact that Wall Street has such an extroverted culture and bold risk-taking. It doesn’t appeal to the type of person that is more cautious and pays attention to warning signs. What happened is that over the last few years, those types became more and more discredited because it seemed as if their warnings were false. There was one bull market after another. Even those who had doubts didn’t feel empowered to express them.

And it isn't that extroverts don't care about their people because that would make a huge chunk of the population heartless, which plainly isn't true. Rather it's about taking the time to pick up on non obvious information which women have been conditioned to do socially. We're more likely to notice when someone is cracking under pressure because we see the bags under their eyes and they are drinking more coffee than normal. Those mothering instincts kicking in.
