Frequently asked questions
What are the Big Five personality traits of successful entrepreneurs?
Decades of research consistently show that founders score higher than the general population on openness to experience and conscientiousness, and lower on agreeableness. Extraversion and emotional stability matter but are less reliably predictive of long-term startup success. The most replicated finding, across more than 100 studies, is that conscientiousness is the single strongest Big Five predictor of business performance.
Which Big Five trait best predicts startup success?
Conscientiousness. Meta-analyses spanning over 100 studies (Zhao & Seibert 2006; Zhao, Seibert & Lumpkin 2010) consistently find conscientiousness is the strongest Big Five predictor of both entrepreneurial intention and venture performance. It captures goal-directed behavior, planning, organization, and follow-through, all of which compound over the years required to build a successful company.
Are founders more or less agreeable than the general population?
Less agreeable, on average. Successful entrepreneurs tend to score lower on agreeableness than non-entrepreneurs. Low agreeableness correlates with the willingness to make tough decisions, negotiate hard, push back against investor pressure, and resist the social pull toward consensus. This is one of the most counter-intuitive findings in personality and entrepreneurship research.
Is Big Five more reliable than MBTI for assessing founders?
Yes. The Big Five model is the most scientifically validated personality framework in existence, with over 50 years of peer-reviewed research establishing its reliability and predictive validity. MBTI sorts people into 16 discrete boxes and has lower test-retest reliability. The Big Five measures traits on continuous scales, producing a more accurate picture of personality. Many MBTI dimensions correlate with Big Five dimensions (E/I with extraversion, N/S with openness, T/F with agreeableness, J/P with conscientiousness), so the two can be used together.
