2D:4D Ratios and Gender Differences in Individual Preferences and Behavior

with Katharina Reitsamer

This study examines the relationship between 2D:4D finger digit ratios and economic preferences and behaviors in a large-scale dataset of over 1000 individuals from the Sub-Saharan country Ghana. Despite previous research suggesting links between digit ratios and various traits and behaviors, including those related to economics, our study does not find significant associations. We build upon recent research, employing incentivized measures of economic preferences and behavior and a substantial sample size. Our findings contribute to the ongoing debate surrounding the validity and predictive power of digit ratios in measuring prenatal hormone exposure and their association with human behavior.
