The Broken Rung Is an Access Problem, Not an Ambition Problem
Eleven years of pipeline data say the same thing about the first promotion. For every 100 men moved up to manager, 93 women are. For Asian women and Latinas it is 82. For Black women it is 60. That is the broken rung, and it has held for eleven consecutive years of the Lean In and McKinsey Women in the Workplace study.
This year the same report added a finding that sounds like it undercuts the structural argument entirely. For the first time, there is a measurable gap in who wants the next job. Eighty percent of women say they want to be promoted to the next level, against 86 percent of men, and the gap is widest at the entry and senior levels.
That number is going to get used against you. It is the cleanest available support for the oldest explanation in the building: she did not want it enough.
Read one line further and that explanation collapses. When women and men have sponsors and comparable support from their managers and senior colleagues, the gap in desire to advance disappears. Entry-level women who already manage people are just as likely as men to want the next job.
Ambition is not the input in this data. It is the output. What the survey captured is not how much women want. It is what they have watched happen.
What the rung is actually measuring
The promotion to manager is the only one in a career that is not primarily a reward for work already done. It is a bet on work not yet done, and bets run on a different currency.
The strongest recent evidence on this is Alan Benson, Danielle Li and Kelly Shue, writing in the February 2026 American Economic Review. Across 29,809 management-track employees, they found that women received higher performance ratings than men and substantially lower potential ratings. That potential gap accounted for roughly half of the entire gender promotion gap. The ratings were also wrong. The women who were rated lower on potential went on to outperform the men promoted alongside them.
This is one large, recent, peer-reviewed study rather than a replicated body of work, so hold it as strong evidence rather than settled law. But it matches what the pipeline shows. Performance is what gets you rated. Potential is what gets you promoted. And potential is not observed. It is asserted, by someone senior enough for the assertion to count, in a room you are probably not in.
Which makes the rung a proximity test wearing a performance test’s clothing.
Access is the variable
That is why this sits under Access rather than Authority. Authority is whether your judgment is recognized. Access is whether you are close enough to the decision for anyone to recognize it in time.
The same report puts a number on the distance. At entry level, 31 percent of women report having a sponsor, against 45 percent of men. That gap narrows at mid level and again at senior level, which means the scarcity is worst exactly where the rung is. And sponsorship is not a soft benefit. Sixty-five percent of employees with a sponsor were promoted in the last two years, compared with 35 percent of those without one.
So the sequence is not complicated. Potential drives the first promotion. Sponsors are the people who assert potential. Women have fewer of them at precisely the level where it decides the most. The ambition gap is the rational read of that arithmetic by women who have been watching it for a few years.
Which is useful, because arithmetic is something you can act on.
Three moves
Find out who actually decides, and what reaches them. You are probably optimizing for your manager. The first promotion is usually settled in a calibration conversation among several leaders, most of whom have never seen your work directly. Name those people. Then ask your manager one question: what evidence about me goes into that room, and who says it out loud?
Convert one mentor into a sponsor with a specific ask. Mentorship is advice. Sponsorship is someone spending their own credibility on you when you are not there. Most mentors never make the jump because they were never asked to. Go to one of them with the role, the room, the timing, and the two sentences you want said. Specific asks get acted on. General ones get encouragement.
Make sponsoring you an obvious win. Coqual’s Sponsor Dividend research found that sponsors benefit measurably from sponsoring, with 87 percent of sponsors highly engaged at work against 73 percent of non-sponsors, and leaders who sponsor talent across difference more likely to be promoted themselves. Give your sponsor the material that makes their bet look sharp: a result they can quote, a metric that closed, a risk you called early. You are not asking for a favor. You are handing them a win they can spend.
The broken rung is not a referendum on how much you want it. It is a measure of how far you are standing from the room where potential gets assigned. That distance is measurable, and it is the thing to work on.
