Research by Simon Baron-Cohen, a professor at England's Cambridge University, finds that men are wired to be better "systematizers" while women are better empathizers.
As systematizers, men tend to pursue jobs that require more breaking down and mastering of systems (car repair, oil exploration, electrical engineering). Women, by contrast, tend to choose empathy-focused jobs (teaching, psychology, social work).
The findings of Baron-Cohen, the first cousin of actor and comedian Sacha Baron Cohen (Borat), reinforce the importance of empathy. You'll build trust with both males and females by attempting to understand their point of view before you propose ideas or issue directives.
