Height in women predicts maternal tendencies and career orientation
Denis K. Deady and Miriam J. Law Smithb
Previous research has shown that variation in sex-specific personality traits in women can be predicted by measures of physical masculinisation (second to fourth digit ratio and circulating testosterone). This study aimed to test the hypothesis that certain sex-specific traits in women (maternal tendencies and career orientation) could be predicted by one index of masculinisation, height. Data was collected via online questionnaires. In pre-reproductive women (aged 20–29, n = 679), increasing height related to decreasing maternal personality (lower importance of having children, lower maternal/broodiness) and decreasing reproductive ambition (fewer ideal number of children, older ideal own age to have first child). Increasing height also related to increasing career orientation (higher importance of having a career, and higher career competitiveness). In post-reproductive women (aged over 45, n = 541), increasing height related to decreased reproductive events (fewer children, had first child at older age) and increased career orientation. Results provide further support for previous studies that show physical masculinisation is associated with psychological masculinisation.
