Harvard Business Review: Gender equality remains frustratingly elusive. Women are underrepresented in the C-suite, receive lower salaries, and are less likely to receive a critical first promotion to manager than men. Numerous causes have been suggested, but one argument that persists points to differences in men and women’s behavior. Harvard Business Review recently investigated whether gender differences in behavior drive gender differences in outcomes. After analyzing data, it was discovered that almost no perceptible differences existed in the behavior of men and women. So if behaviors are the same, what explains the differences in outcomes? HBR concluded it may be due to bias, not differences in behavior.
