- More attention must be paid to the multidimensional nature of competitiveness to better understand how competitiveness relates to personality and gender. We focus on three dimensions: Desire to Win (DW), Personal Development competitiveness (PD), and Enjoyment of Competition (EC). Our empirical exploratory analysis is based on a large sample of 1520 individuals. We control for interdimensional correlations, correct for multiple testing, and use conservative thresholds to provide robust evidence on dimension-specific associations of competitiveness with personality, operationalized via the HEXACO framework, and gender. Independent of the respectively other competitiveness dimensions, DW relates to less honesty-humility and less agreeableness, PD to more emotionality, and EC to more extraversion and less emotionality. EC is the sole source of gender differences among the correlated competitiveness dimensions.
