Women in business are constantly told that confidence matters. Books are written about it. Coaches are paid to develop it. Whole industries — workshops, retreats, courses — exist to help women become more confident. The premise behind all of this is that confidence is the missing ingredient that explains why women advance more slowly than their male peers.
This premise is partly right. It’s also partly misleading, and the misleading part has caused serious damage.
What women are actually told to develop, when they’re told to develop confidence, is performance of confidence. The visual signaling of confidence: assertive body language, declarative statements, comfort with interruption, ease with public disagreement. The argument is that women who perform confidence will be perceived as more competent, will receive more promotions, and will close the gap with their male peers.
There’s truth to this. Performed confidence does shift perceptions. Women who project decisive energy in rooms full of senior executives do tend to be taken more seriously. The performance has measurable career value.
But performance of confidence is not the same as actual confidence. And conflating the two has produced specific costs.
Actual confidence is internal. It comes from competence, from earned experience, from track record, from understanding what you’re good at and what you’re not. It manifests as calibrated certainty — confidence about things you actually know, openness about things you don’t. It produces decisions that hold up over time.
Performed confidence is external. It’s the projection of certainty regardless of whether the certainty is warranted. It manifests as uniform decisiveness — strong opinions about everything, regardless of how much you actually know. It can produce decisions that fall apart on contact with reality.
The damage from confusing the two: women who’ve been coached to perform confidence often start mistaking the performance for the underlying capability. They project certainty in domains where they don’t actually have expertise. They make decisions with insufficient information because hesitation has been pathologized. They suppress legitimate doubts because expressing doubt is “lacking confidence.” Over time, the performance erodes the actual underlying judgment.
The most successful women in business tend to operate from a different principle. They are not performatively confident. They are competently humble. They speak with conviction about things they understand deeply and ask questions about things they don’t. They’re comfortable saying “I don’t know” or “I need to think about that.” They make decisions that reflect actual knowledge rather than projected certainty.
This is harder to perform than the confidence-coaching model suggests. It requires actually knowing what you know and don’t know, rather than projecting confidence uniformly. But it produces better outcomes long-term, both in decision quality and in the trust other people develop in you.
The replacement for “perform confidence” is not “be hesitant.” It’s “develop the actual underlying competence that warrants confidence in specific domains, and be comfortable with calibrated uncertainty everywhere else.” This is harder advice. It’s also more useful.
The senior executives who command rooms most effectively are usually not the ones with the most uniform certainty. They’re the ones who can say “I’m certain about A, fairly confident about B, and genuinely don’t know about C,” and have the discipline to operate accordingly.
The takeaway
Confidence theater is a short-term career hack with long-term costs. The women who advance furthest are usually the ones who develop calibrated judgment rather than uniform projection. Stop performing certainty. Start developing it.
