Women vs Men in Leadership: The Numbers

Twelve measures of leadership representation and outcomes, side by side. The data now consistently debunks the idea that men are the natural default for leadership roles.

What the numbers say

The research case for 'men as natural leaders' has collapsed. Meta-analyses of effectiveness, subordinate evaluations, legislative output, and company performance all point the same way — women lead as well as or better than men once they get the chance. What persists is the pipeline leak: the 'broken rung' at first-manager promotion, the likability penalty for agentic behavior, and the double bind that Heilman's research has been documenting for 25 years. The gap is in selection, not performance.

Frequently asked

Do women make worse leaders than men?

No. Meta-analyses of 99 samples (Paustian-Underdahl 2014) and 360° reviews of 60,000+ leaders (Zenger Folkman) find women rated equal or slightly higher on effectiveness. The data doesn't support the stereotype.

Why do so few women reach the top?

The 'broken rung' — first-manager promotion — is the biggest pipeline leak. Women get promoted to manager at 81% the rate of men despite comparable performance. Compounding over a career produces the executive gap.

What is the 'double bind'?

Heilman and others document that women leaders face penalties for both warmth (seen as weak) and agency (seen as unlikable). Men can be either without equivalent penalty. It makes the same behavior cost women more.

Do companies with women leaders perform better?

McKinsey's 2023 'Diversity Matters Even More' found top-quartile gender-diverse executive teams were 39% more likely to outperform peers on profitability. Earlier years showed smaller but consistent effects.

Has employee preference for bosses changed?

Dramatically. Gallup's stated preference for a male boss has fallen from 66% in 1953 to 22% today. Most US workers now report no preference either way.
