Fig. 6: Variability in opportunity costs for others relates to empathy and utilitarianism.
From: Humans are more prosocial in poor foraging environments
a Individual factor loadings for the subscales of the questionnaires administered (n = 508). Our factor analysis revealed three dimensions of behaviour related to psychiatric traits, empathy and emotional motivation, and utilitarianism. Note: the loadings displayed here are absolute values; coloured bars represent loadings > 0.30. b The factors ‘Empathy and emotional motivation’ and ‘Utilitarianism’ are related to opportunity costs when deciding for others in both rich and poor foraging environments. Those who are more empathetic and emotionally motivated, or with stronger utilitarian beliefs, may find helping others less costly and may be more willing to interrupt their behaviour to help others. Error bands represent the standard error of the mean; r values represent Pearson’s correlation coefficient; p-values are two-sided and FDR-adjusted.
