Abstract

This study examines how entrepreneurial personality traits influence business outcomes among underrepresented minority entrepreneurs in the United States. Specifically, it investigates the effects of entrepreneurial self-efficacy, locus of control, risk tolerance, and extraversion on entrepreneurial performance, as well as the moderating role of grit and the mediating role of business networking. Although underrepresented minority entrepreneurs contribute significantly to innovation and economic growth, they continue to face persistent barriers, including limited access to capital, mentorship, and supportive entrepreneurial ecosystems. Guided by Trait Theory of Entrepreneurship and Social Cognitive Theory, this study employed a quantitative, cross-sectional survey design with embedded open-ended questions using validated measures. Results indicate that entrepreneurial self-efficacy and extraversion are strong predictors of entrepreneurial performance, while grit strengthens the relationship between personal traits and outcomes. Business networking partially mediates the relationship between extraversion and entrepreneurial performance, underscoring the importance of persistence and relational capital. Open-ended responses provided additional context regarding how entrepreneurs demonstrate resilience and adaptability in navigating structural challenges. Overall, the findings advance understanding of the psychological and social mechanisms that support entrepreneurial performance and offer practical implications for promoting inclusive entrepreneurship.
