Missed opportunities: When prejudice holds women and companies back

It still happens far too often: a woman leads a project with flying colors for months, achieves results that convince even skeptics, and when it comes to the decision on her successor, her male colleague gets the job. The reason: he «appears more like a leader.» No figures, no evaluation. Just perception. Just habit.

Such stories are not isolated cases. They are symptomatic of a system that measures performance but rewards perception. In many companies, it is not what someone can do that counts, but how they come across. And this is precisely where unconscious biases come into play – biases that are deeply ingrained in structures, routines, and decision-making processes.

The price to pay is high: systematically overlooking talent means squandering innovative strength, motivation, and economic potential. A global study by the International Labor Organization (ILO, 2021) involving over 12,000 companies in 70 countries clearly shows that companies with diverse management teams are more successful. Two-thirds of them increased their profits – most by 10 to 15 percent. Progress was particularly significant in innovation, talent acquisition, and social engagement.

Distorted perception: How unconscious biases work

Unconscious thought patterns—known as unconscious biases—influence decisions in companies every day. They are not a sign of unfairness, but rather an expression of how our brains work: They look for shortcuts to reduce complexity. Under pressure, uncertainty, or time constraints, it relies particularly heavily on these automatic responses – precisely where management decisions are made.

Biases are particularly evident when it comes to women in leadership roles:

• Performance bias: Women's performance is evaluated more strictly, while men are more often attributed potential.
• Similarity bias: People prefer to promote those who resemble them – in appearance, language, or career path.
• Motherhood penalty: Women with children are often considered less available or ambitious – regardless of their actual performance.
• Confirmation bias: Information that confirms existing expectations («women are more emotional, men are more analytical») is more likely to be perceived – and less likely to be questioned.

Data shows that these are not isolated cases. According to McKinsey's global study Women in the Workplace, women get stuck early in their careers – not because they perform less well, but because they are less likely to be promoted to senior management positions. Researchers call this the broken rung effect: the «missing rung» on the career ladder.

A recent study published in 2024 in the journal Leadership Quarterly confirms that unconscious biases in talent processes slow down diversity – and thus innovation and competitiveness. The consequences are measurable: fewer prospects, less momentum in innovation processes, and declining attractiveness as an employer.

The ILO report (2021) highlights this discrepancy: 92 percent of managers feel included in their company – but only 76 percent of employees. This gap shows how much lived inclusion is conceived at the top but rarely anchored across all levels. And it comes at a cost – motivation, creativity, and ultimately economic success.

Best Practice: How a private equity company is strengthening female leadership with the support of MANRES – and thereby increasing performance

Growth, returns, performance – in the private equity business, these terms are part of everyday language. This is also the case for our client, a company with numerous investments in Europe. But behind the numbers, there was a silent gap: too few women in leadership positions. The data was clear – the potential was there, but too often it remained invisible. Structural barriers, unconscious bias, and internalized patterns held talent back long before it could even become visible.

We won over the company with our expertise, female psychologists, and managers with many years of experience in a pitch. The company wanted to further develop its support program for female managers and no longer treat it as a «diversity initiative,» but as a strategic investment in performance. The result was the Female Leadership Program—not a symbolic project, but a catalyst for sustainable change.

In four intensive workshops, female executives from various portfolio companies worked on key questions relating to their leadership: How can authentic authority be achieved in a male-dominated environment? How can self-doubt and imposter syndrome be overcome? And how can influence be gained without conforming?

The results spoke for themselves:

• Noticeably greater self-confidence and visibility for female talent.
• A strengthened network across company boundaries.
• More women in talent pools and succession processes.
• A new perception: female leadership was no longer seen as a “supplement” but as a strategic success factor.

The program demonstrated what research has long proven: when women develop their potential, the entire organization benefits—both culturally and economically. Promoting women is not an additional project, but a performance driver.

Where bias is reduced, the quality of decisions improves – and with it the performance of the company. Another study by the ILO (2021) underscores that companies that understand diversity as a strategic success factor are 21 percent more likely to report fair career opportunities and 15 percent more likely to report innovation impulses.

Five levers for real change

1. Make bias visible – through a structured bias audit

Unconscious biases influence HR decisions more than many managers realize. A bias audit reveals where systematic patterns are at work in promotions, talent lists, performance reviews, or compensation systems. Studies show that up to three-quarters of the criteria in talent processes are implicit and hardly structured – a major reason for unequal treatment.

Only by looking at past decisions, supplemented by interviews or short pulse surveys, can we see where perceptions diverge and bias plays a decisive role. Transparency is crucial: when decision-making routines become visible, awareness is created – and with it the basis for fairer, more transparent personnel decisions.

Impact: Transparency creates awareness – and awareness is the prerequisite for change in decision-making architectures.

2. Creating objectivity – through potential diagnostics

As long as potential is not measured objectively, gut feeling prevails – and that is rarely free of bias. Potential diagnostics reveal what is often overlooked: not only past performance, but also future viability – learning agility, self-management, systemic thinking.

Companies that consistently use such models make up to 30 percent better staffing decisions and significantly increase diversity in key roles. Objective potential analyses reveal talent that would otherwise go unnoticed – often women or career changers.

Impact: Potential becomes measurable – and talent that was previously overlooked becomes visible.

3. Enabling development – with leadership programs for women

Women do not lack ambition, but often lack access: to networks, to sponsorship, to visibility. Leadership programs for women are therefore not a «special path,» but a targeted response to structural barriers.

Programs that promote strategic thinking, personal positioning, and authentic leadership – combined with mentoring and sponsorship – are effective. Studies show that mentoring supports and sponsorship changes careers in the long term. When women are given targeted development opportunities, their leadership confidence grows and with it the number of female talents in key roles.

Impact: Programs create performance visibility and promote internal leadership growth.

4. Empower decision-makers – reduce bias, increase responsibility

Real change does not come about through training alone, but through new decision-making architectures. Workshops with management teams reveal unconscious patterns and create structures for fair personnel decisions: clear criteria, structured interviews, peer review.

When top management takes responsibility and reflects on its own decision-making mechanisms, the system changes. A study by MIT Sloan shows that bias-proof decision design significantly increases the quality of HR decisions and measurably reduces unconscious bias.

Impact: less gut feeling, more accountability, and greater credibility for the leadership culture.

5. Sustainable anchoring – through cultural architecture and management systems

The advancement of women remains ineffective if it is treated as an HR project. It only becomes sustainable when it is part of the organization's DNA. This means clear career paths, binding feedback loops, and integrative management principles that structurally secure development.

Edgar Schein calls this cultural anchoring—anchoring equality in systems, not in symbolism. Consistency is crucial: processes, attitudes, and behavior must fit together.

Impact: An initiative becomes part of the performance culture—and equality becomes a strategic success factor.

Typical objections – and the response to them

«Promoting women is preferential treatment.»
Wrong. Preferential treatment would mean ignoring performance. Promoting women means creating equal opportunities, making performance visible, and correcting distorted processes. It's not about special rights – it's about fairness.

«We just can't find any women.»
The problem rarely lies in the talent market, but in the talent filter. Those who review and specifically develop their decision-making processes will find talent – both internally and externally. Diversity is not a coincidence, but the result of conscious selection.

«We tried that, it didn't work.»
Individual measures are of little use if the system remains the same. Change requires structure: cultural diagnostics, clear responsibilities, and management teams that understand diversity as a performance factor – not as a project.

From recognition to action – an action plan for companies

Awareness is the first step – but impact only comes when companies take action. Those who are serious about equality can start changing structures and revealing potential today.

What is possible today:

• Review promotions: Analyze the latest rounds of promotions – by gender, criteria, and decision-making processes. The data will quickly reveal where systematic patterns are at work.
• Establish bias awareness: Address unconscious biases in top management. Change begins where responsibility is held.
• Make talent visible: Identify two to three female high potentials in a targeted manner – and actively promote them through projects, mentoring, or direct visibility with decision-makers.

What works in the medium term:

• Understanding culture: Conduct a cultural diagnosis—ideally with an external partner such as MANRES—to identify blind spots in decision-making structures.
• Redefining potential: Implement potential-based talent models that measure not only experience but also future viability.
• Embrace sponsorship: Establish programs in which leaders take on specific responsibility for developing female talent.

Step by step, this creates a system that doesn't just manage diversity, but lives it, and where equality isn't an add-on, but part of the model for success.

Change begins where we look

Equality is not a project that can be ticked off a list. It is a reflection of how seriously organizations take their own performance culture. Where people are not seen, heard, and supported equally, potential is lost—and with it, future viability.

The good news is that change is possible. It doesn't start with a campaign, but with the courage to question routines. With the willingness to look at numbers honestly, make decisions transparent, and take responsibility.

It doesn't take a revolution to change structures – just consistency. When leaders consciously decide who they give opportunities to, who becomes visible, and who is heard, the culture changes. Step by step, decision by decision.

Ultimately, it's not just about bringing more women into leadership. It's about creating organizations that realize their full potential – human, cultural, and economic. And that starts where we have the courage to take a close look – and decide differently.
