چکیده

The article by Coates et al. (1) adds interesting evidence that a low 2D:4D ratio in men predicts success, not only in sports (2, 3) or music (4), but also in job performance. According to the authors, low-2D:4D traders perform better (i.e., they earn more) because of basic characteristics: rapid visuomotor scanning and physical reflexes. However, they overlook another frugal explanation for their findings. Recently, it has been shown that low-2D:4D men react much more strongly on performance feedback than high-2D:4D men, irrespective of the performance itself (5). When men with a low 2D:4D ratio find themselves in a subordinate status position (e.g., when they lose a game), they might react strongly, e.g., by acting impulsively, or perhaps even abandoning the activity if possible (5). Following this rationale, my hypothesis is that low2D:4D men want to excel and therefore will look for a specific domain (in both hobbies and jobs) where they have the abilities to excel. This idea might help to explain why a low 2D:4D ratio in men is related to better performance in completely different domains such as sports (2, 3) and music (4).The same mechanism might also lead to a better performance in trading in the financial world but needs not be limited to this type of job. I expect low-2D:4D people to outperform high-2D:4D people in all kind of competitive jobs, sports, and other activities, not because of specific physical characteristics, but because of one specific psychological characteristic: a higher need for achievement.
