Resumen
We study how the ratio between the length of the second and fourth digit (2D:4D) correlates with choices in risk and social preferences elicitation tasks by building a large dataset from six experimental projects with more than 900 subjects. We find that social preferences are weakly significantly lower when 2D:4D is above the median value and, in addition, we find that they vary significantly with cognitive ability. When we look at risk preferences, we find that a high 2D:4D is not significantly associated with the frequency of subjects’ risky choices. Finally, when we look at personality traits, we find no significant association, except for some significant association with individual questions used to obtain personality proxies.
