Individual religiosity relates to prosocial attitudes, behavioral intentions, and behaviors of minimal (no/low cost; limited to in‐group members) prosociality in hypothetical situations. Yet evidence on religious prosociality through other‐oriented, costly helping behavior in real life is still to be documented. Similarly, religiosity relates to cognitive, emotional, and attitudinal components of prejudice toward moral out‐groups. Evidence on real behavior of prejudice is nevertheless still needed. In two experiments using the same measure of religiosity and samples from the same population, religiosity predicted helping, in a real‐life context, of an in‐group member in need (Experiment 1) as well as overt and direct aggression by means of allocating hot sauce to a gay, but not to a neutral, target (Experiment 2). Religious prosociality and aggression are real, concern distinct kinds of targets, and are at the heart of personal religiosity.
