STEM fields: Welcoming in theory, intimidating in reality?

STEM fields are often described as spaces of equal opportunity, where success depends on talent and effort. In theory, they are open to everyone. However, research shows that women still experience these environments differently, often finding them less inclusive than expected.

As students move from academic settings into real-world environments, these differences become more visible. This gap is not only the result of structural inequalities, but is also strongly shaped by implicit gender stereotypes that influence how individuals perceive themselves and their place in STEM.

The gap between theory and reality

Education systems promote equal access to STEM, aligning with global goals such as those highlighted in UNESCO’s Education 2030 report, which emphasizes gender equality in education.

However, equal access does not always translate into equal experience. While classrooms may appear inclusive, underlying biases continue to influence participation, confidence, and long-term engagement in STEM fields.

Recent data shows that women represent only around 35% of STEM students globally, highlighting that this gap remains significant despite progress.

The role of implicit stereotypes

The study by Beroíza-Valenzuela (2025) demonstrates that gender stereotypes in STEM are often implicit, meaning they operate unconsciously. Using reaction-time measurements, the research shows that people tend to associate STEM fields more quickly with men than with women.

These automatic associations can affect self-perception, confidence, and the sense of belonging. Even without explicit discrimination, such cognitive biases can discourage women from fully engaging in STEM environments. Over time, these small effects accumulate and shape career choices and persistence.

Structural barriers and the glass ceiling

In addition to stereotypes, structural inequalities persist. The study published in Frontiers in Psychology (2017) on the glass ceiling highlights how women face invisible barriers in career advancement.

Despite equal qualifications, women are often underrepresented in leadership roles and decision-making positions. This suggests that the issue is not only participation, but also progression within STEM careers.

Real cases and lived experiences

Research findings are also reflected in real-world testimonies. Reshma Saujani, founder of Girls Who Code, explains that many girls feel out of place in STEM environments, especially when they are among the few women in the room.She highlights that girls are often socialized to avoid failure, which affects their confidence and willingness to take risks in technical fields. This illustrates how internalized stereotypes, not ability, can shape participation in STEM.

These lived experiences reinforce what research already shows: exclusion is not always explicit, but often subtle and cumulative.

Why does this matters?

According to UNESCO, achieving gender equality in education is essential for both fairness and global development. Gender disparities in STEM limit diversity, innovation, and the overall effectiveness of these fields. Encouraging more inclusive environments is not only a social issue, but also a scientific and economic necessity.

STEM fields may appear inclusive in theory, but research reveals a more complex reality shaped by implicit biases and structural barriers. Addressing these challenges requires more than equal access—it requires actively recognizing and reducing the hidden factors that continue to influence women’s experiences.

By becoming more aware of these mechanisms, we can begin to challenge stereotypes, support greater confidence among women, and contribute to building STEM environments where everyone truly belongs.
