Religious individuals are often associated with moral values closely related to prosociality, such as charity and selflessness. In this paper, I focused on the influence of religion on prosociality in economic decision-making. The goal was to test if religiosity is related to increased overall giving. Further, I predicted that religiosity is inversely associated with ingroup bias due to the religious participants’ increased prosociality. To test this assumption, I used an economic game in which participants had to divide money between an in- and outgroup recipient. While there was a significant effect of ingroup bias in the sample overall, religiosity did not relate to ingroup bias. Religious participants did not give more money to recipients regardless of their in- or outgroup status than non-religious ones overall, nor did they show reduced ingroup bias. Perhaps the sample size or the study’s setup was not appropriate to detect significant results for the effect of religiosity. Alternatively, religiosity is genuinely not associated with reduced ingroup bias nor increased overall giving because religious people might not be more prosocial than non-religious ones. Finally, it could also be that religiosity only matters in the context of ingroup bias when the in- and outgroups are related to religious identities (e.g., Christian ingroup and Muslim outgroup).Show less
