What is stereotype threat and how does it affect test performance?
Stereotype threat is the psychological experience of being at risk of confirming a negative stereotype about your group, which can create anxiety and mental distraction that hurts performance. A 2025 meta-analysis of adult cognitive tests confirmed that stereotype threat can lower scores for stereotyped groups, while also showing a 'stereotype lift' effect where non-stereotyped groups sometimes perform better when reminded of the stereotype [4]. For example, women reminded of the stereotype that men are better at math may underperform on a math test, while men may perform slightly better.
However, the effect is not automatic. A 2025 study of over 400 students taking the GRE found no overall race-by-condition interaction (meaning Black students didn't universally underperform when stereotype threat was activated) [1]. Instead, the key factor was working memory capacity: Black students with higher working memory capacity scored higher under stereotype threat, suggesting that mental resilience can buffer the negative effects [1].
Who is most vulnerable to stereotype threat on standardized tests?
The evidence shows that vulnerability varies by group and context. A 2025 study of students of migrant descent in Austria found that second-generation students (those born in the country to immigrant parents) performed worse on a standardized test under stereotype activation, while first-generation students (born abroad) showed no significant effect [2]. This suggests that identity and acculturation play a role—second-generation students may be more aware of negative stereotypes about their group.
Social class also matters. A 2023 field experiment in China with over 1,500 migrant students found that lower-class students (those with rural household registration) were more affected by stereotype threat on an English test, and that a brief self-affirmation exercise (writing about core values) improved their scores by reducing stereotype threat [3]. The intervention took only 15 minutes and cost almost nothing, yet it significantly boosted performance for disadvantaged students [3].
When does stereotype threat NOT affect test scores?
Stereotype threat does not always produce measurable effects. A 2024 experiment with 40 female undergraduates found no effect of gender-related stereotype threat on arithmetic scores or IQ test performance, despite 67.5% of participants failing the arithmetic test overall [5]. The authors concluded that poor math skills, not stereotype threat, were responsible for the failures [5]. This highlights that stereotype threat is not a universal explanation for performance gaps—it only applies under specific conditions, such as when the stereotype is salient and the test taker cares about the domain.
Even in studies that find effects, the size of the impact can be small or inconsistent. The 2025 meta-analysis noted that stereotype lift (the boost for non-stereotyped groups) is less commonly studied and may be smaller than the threat effect [4]. Researchers caution that replication issues and statistical power problems mean some findings may not hold up in larger, more rigorous studies [1].
