The Confidence Trap: How Companies Misjudge Talent—and Lose Their Best Leaders
The corporate world has a measurement problem that’s quietly distorting one of the most consequential decisions companies make: who gets promoted. According to McKinsey’s latest Women in the Workplace report, for every 100 men promoted to first-time manager, only 81 women move up, creating a “broken rung” where the gap begins and later widens as careers progress. Women of color face even steeper odds, with the explanation lying not in a pipeline problem or a confidence deficit, but in a measurement failure that’s costing companies their best talent.
This measurement failure has real economic costs, with research showing that less diverse leadership teams make weaker strategic decisions and correlate with lower innovation and reduced long-term financial performance. In other words, the broken rung doesn’t just limit careers; it drags on competitiveness. Economist Alan Benson and his colleagues analyzed promotion data from nearly 30,000 management-track employees in 2024 and found that women consistently outperformed men in their current roles, yet received lower ratings for “potential.” More damning still, those potential ratings didn’t predict future success, with women labeled as having less potential going on to outperform male colleagues with identical scores.
Uncovering the Root Cause
The problem compounds in how feedback gets delivered, with large-scale text analysis conducted in 2024 by Textio showing that women’s performance reviews disproportionately focus on personality traits and labels, such as “abrasive,” “too nice,” and “emotional,” rather than on business impact. Men’s reviews, by contrast, center on business outcomes and technical skills. This creates a dynamic where men advance on what they could do, while women must prove what they have already done. The root cause of this issue lies in companies confusing confidence with competence, with factors like “executive presence” and “gravitas” carrying outsized weight and masking bias.
Calibration meetings, designed to standardize ratings, can amplify this dynamic, with confident storytelling trumping comparable results. The loudest voice in the room isn’t necessarily the most capable leader, and high performers vote with their feet when they realize the system rewards storytelling over results. The legal and reputational risks of gendered review language only add to the fallout. Treating rigorous vetting as a feature, not a bug, is poor governance and even poorer business strategy.
Fixing the Problem
A growing number of companies are rejecting vibes-based promotion in favor of evidence-based advancement, treating potential as a hypothesis that requires proof, not a halo that justifies advancement. To fix the problem, companies can define potential concretely, specifying measurable competencies such as learning agility, decision quality, and enterprise thinking. They can also audit the ratings that gate opportunity, running quarterly audits comparing potential scores to performance ratings, broken down by gender and race.
Replacing confidence tests with readiness trials, such as 90-day live assignments, can also help, with success metrics established upfront and outcomes speaking for themselves. Banning trait-only feedback in calibration and reframing the opportunity itself can also make a difference, with women declining promotions not due to insufficient confidence, but due to poorly designed or unsupported roles. Monitoring language and using tools that flag gendered patterns in performance reviews can also help.
Metrics that Matter
To measure progress, companies can track metrics such as promotion speed, stage conversion, first-year impact, time to full productivity, and audit gap. These metrics can provide a clear picture of where progress is blocked and where the system is failing. By tracking these metrics, companies can identify areas for improvement and make data-driven decisions to fix the problem.
For executives and boards, the question isn’t whether this bias exists – the data has settled that. The question is whether they’re willing to measure what they currently take on faith and act on what they find. By doing so, companies can build deeper leadership benches, experience fewer flameouts among newly promoted managers, and shorten the time-to-impact on critical work. In markets that reward disciplined execution, competitive advantage may come down to something deceptively simple: raising the evidentiary bar for everyone.
