In the twenty-first century, cultural notions of gender continue to impact the representation and performance of women in the United States Armed Forces. Though the predominant literature does claim that stereotypes and bias may slow the progress of women, the suggestion that stereotype threat may be undermining women's performance has never been made. I hypothesize that when gendered stereotypes are reinforced within the military setting, increased vigilance and a hampered sense of belonging often result for women. Increased vigilance results because women become ultra-sensitive to the stereotypes they might confirm and are subsequently preoccupied with disconfirming that stereotype. A hampered sense of belonging to the military culture women elect to join may result from perceiving that they are not taken seriously and are thought less capable than others by members of their community. The central question of this investigation seeks to understand whether or not stereotype threat undermines the job performance of United States servicewomen. Because gendered stereotypes are often negative and ubiquitous in the military, the employment of these stereotypes can have detrimental effects on the performance of individuals for whom those stereotypes may be relevant. This paper will discuss Claude Steele's Stereotype Threat theory, it's application to women in the United States military, an experimental proposal, and the implications of such research. If the underperformance of women stems from stereotype threat in the military context, steps needed to overcome stereotype threat and enhance performance can be taken.
