Masculinity and Lying

Using a sender-receiver game, the study evaluates how markers like the second-to-fourth digit ratio (2D:4D), facial morphometric masculinity (fMM), and facial width-to-height ratio (fWHR) influence lying and deception. The findings shed light on the biological roots of strategic communication and its connection to honesty and dishonesty.

The dataset includes measurements of 2D:4D, fMM, and fWHR from 168 male participants who played a sender-receiver game. Behavioral data include lying and deception decisions, alongside demographic and physical information such as BMI & age.
