Anonimity, cooperation and facial symmetry

<p>The project investigates how visible morphological features, such as facial fluctuating asymmetry, facial masculinity, and digit ratio (2D:4D), influence cooperation in social dilemmas. Using a series of Prisoner’s Dilemma games under anonymous and non-anonymous conditions, the study evaluates the relationship between these physiological traits and cooperative decisions.</p> <p>The dataset includes measurements of facial fluctuating asymmetry, facial masculinity, and 2D:4D digit ratios from 176 male participants aged 18-28. Data also capture behavioral outcomes from nine stages of Prisoner’s Dilemma games, including anonymous and non-anonymous interactions, alongside participant demographics.</p>
