A study led by Dr. Nitya Chawla of University College London suggests that high intelligence in women often triggers perceptions of hostility. Published in the Journal of Applied Psychology, the research indicates that women face greater workplace mistreatment than men with similar cognitive abilities.

The 800-participant study on cognitive bias and hostility

According to the report, Dr. Nitya Chawla and her team gathered data from more than 800 participants organized across 140 different teams. The researchers utilized cognitive ability assessments to establish a baseline of intelligence, then asked colleagues to rate one another on specific attributes, including supportiveness and perceived hostility.

The findings, as reported in the Journal of Applied Psychology, highlight a distinct divergence in how competence is perceived based on gender. While men with high cognitive scores were often met with increased support and positive perceptions, women with equivalent intelligence levels were more likely to be viewed as hostile. This suggests that in many professional environments , intellectual prowess in women is unconsciously decoupled from warmth, leading to a social penalty for being highly capable.

The 'coldness' trap from Margaret Thatcher to Kamala Harris

This modern workplace friction is not an isolated phenomenon but part of a long-standing societal pattern. The research notes that historically powerful women—including Margaret Thatcher, Angela Merkel, Hillary Clinton, and Kamala Harris—have frequently been characterized as cold or unlikeable. This suggests a persistent gendered expectation where women are expected to prioritize communal warmth over individual competence.

When women break this mold by demonstrating high intelligence, they often encounter a "frothy churn of backlash." This dynamic creates a professional paradox: the very skills that should accelerate a woman's career—analytical brilliance and decisive leadership—become the catalysts for social isolation. this pattern echoes decades of gendered stereotypes that frame female authority as abrasive rather than authoritative.

How exclusion from informal networks stalls senior leadership

The consequences of these perceptions extend far beyond hurt feelings or awkward office dynamics. dr. nitya Chawla warns that the social costs of this bias manifest as diminished professional advancement and lower retention rates for women.. Because highly intelligent women are perceived as hostile, they are less likely to receive offers of help or be invited into the informal mentorship circles that are often critical for promotion.

Exclusion from small-talk circles and casual discussions can gradually erode a woman's sense of belonging within an organization. As these interpersonal setbacks accumulate, the result is a systemic underrepresentation of women in senior leadership positions. the study suggests that unless organizations create structures that reward merit without prejudice, the "tilted playing field" will continue to push qualified women out of the pipeline.

The missing link between cognitive tests and peer perception

While the findings are compelling, several specific details remain unverified in the source report. For instance, the study does not specify which types of cognitive ability assessments were used to measure intelligence, nor does it break down the results by industry to see if these biases are more prevalent in male-dominated fields like STEM compared to others.

Furthermore, the report focuses exclusively on the perceptions of the colleagues and the findings of the University College London researchers . It does not provide a counter-perspective or data from the women themselves regarding whether they intentionally adopt a more assertive communication style to compensate for these biases. Whether these perceptions are a result of the observers' biases or a reaction to specific behavioral differences remains an open question.
