Stereotype threat, the concern about being judged in light of negative stereotypes, causes underperformance in evaluative situations. However, less is known about how coping with stereotypes can aggravate underperformance over time. We propose a model in which ongoing stereotype threat experiences threaten a person’s sense of self-integrity, which in turn prompts defensive avoidance of stereotype-relevant situations, impeding growth, achievement, and well-being. We test this model in an important but understudied population: the physically disabled. In Study 1, blind adults reporting higher levels of stereotype threat reported lower self-integrity and well-being and were more likely to be unemployed and to report avoiding stereotype-threatening situations. In Study 2’s field experiment, blind students in a compensatory skill-training program made more progress if they had completed a values-affirmation, an exercise that bolsters self-integrity. The findings suggest that stereotype threat poses a chronic threat to self-integrity and undermines life outcomes for people with disabilities.
