Rationale: Stereotype threat refers to being at risk of confirming, as one's own individual characteristic, a negative stereotype about one's group (for example, that women aren't good in math or Blacks aren't good academically).¹ Stereotype threat can have an impact on performance. For example, when a test of mental rotation was introduced as linked to success with regard to in-flight and carrier-based navigation engineering, nuclear propulsion engineering, etc., there was a large gender gap favoring males. When it was introduced as linked to clothing/dress design and interior decoration, the gender difference favoring males was small.² When women and underrepresented men were told that the math test they would be taking did not show differences by gender and/or race, they scored better than they did when they were told the test found gender/race differences.³ Similar results have been found with men in terms of verbal skills and with White men in terms of athletic skills.⁴
