A Harvard Business Review case study of over 7,800 leaders found that women outperformed men in 15 out of 16 measured leadership competencies, with developing a strategic perspective being the only trait dominated by men. While stereotypes suggest that men take charge and women take care, the data shows that qualities like taking initiative, driving for results, and influencing others come more naturally to female leaders. This is likely because women face more uncertainty in the workplace and don't feel fully accepted, pushing them to exceed expectations through their actions and develop strong leadership skills.
