Kinship is a strong predictor of altruism. However, chronic pain is a homeostatic threat to survival that creates a social in-group which we predicted would result in increased altruism over and above kinship, because it is driven by shared empathy. Participants included 139 individuals that were divided into a chronic pain or control group. Participants completed six Prisoner’s Dilemma scenarios with a sibling or chronic pain accomplice. Pain altruism and sibling altruism scores were calculated based on decisions to cooperate with or defect on an accomplice. A mixed ANOVA revealed that there were no significant differences between groups. The marginal difference between the groups suggests that chronic pain may create an in-group altruism that is just as strong as kinship.
