Donating a kidney to a stranger is a rare act of extraordinary altruism that appears to reflect a moral commitment to helping others. Yet little is known about patterns of moral cognition associated with extraordinary altruism. In this preregistered study, we compared the moral foundations, values, and patterns of utilitarian moral judgments in altruistic kidney donors (n = 61) and demographically matched controls (n = 58). Altruists expressed more concern only about the moral foundation of harm, but no other moral foundations. Consistent with this, altruists endorsed utilitarian concerns related to impartial beneficence, but not instrumental harm. Contrary to our predictions, we did not find group differences between altruists and controls in basic values. Extraordinary altruism generally reflected opposite patterns of moral cognition as those seen in individuals with psychopathy, a personality construct characterized by callousness and insensitivity to harm and suffering. Results link real-world, costly, impartial altruism primarily to moral cognitions related to alleviating harm and suffering in others rather than to basic values, fairness concerns, or strict utilitarian decision-making.

Does reading fiction improve our ability to understand one another? Correlational data suggest that lifetime fiction exposure is positively associated with social outcomes. The latest experimental data suggest that fiction reading may slightly improve social ability, although this conclusion is tenuous. Here, we test fiction’s putative causal impact on social outcomes by conducting a randomized controlled study in which adult participants (N=210) were randomly assigned to engage in no reading for pleasure, or to read fiction or nonfiction for 45 min/day, five days/week, for four weeks. At the end of the study, participants were assessed on three classes of social outcomes: theory of mind (ToM), empathy, and social functioning. Contrary to other experimental work, fiction readers did not outperform nonfiction readers or participants who abstained from pleasure reading on any social outcome. Nonfiction readers outperformed those who abstained from pleasure reading on empathy measures. For fiction readers, narrative transportation was positively associated with empathy post-reading, and intrinsic motivation was positively associated with empathy and ToM post-reading. Contrary to other correlational work, we did not observe associations between lifetime fiction exposure and social outcomes. These data are consistent with the following possibilities regarding fiction’s positive impact on social outcomes: such findings may reflect a priming effect, may occur only after prolonged exposure to fiction, and/or may occur for readers who exhibit a particular kind of engagement with the reading.
Most people are much less generous toward strangers than close others, a bias termed social discounting. But people who engage in extraordinary real-world altruism, like altruistic kidney donors, show dramatically reduced social discounting. Why they do so is unclear. Some prior research suggests reduced social discounting requires effortfully overcoming selfishness via recruitment of temporoparietal junction. Alternatively, reduced social discounting may reflect genuinely valuing strangers’ welfare more due to how the subjective value of their outcomes is encoded in regions such as rostral anterior cingulate cortex (ACC) and amygdala. We tested both hypotheses in this pre-registered study. We also tested the hypothesis that a loving-kindness meditation (LKM) training intervention would cause typical adults’ neural and behavioral patterns to resemble altruists. Altruists and matched controls (N=77) completed a social discounting task during fMRI; 25 controls were randomized to complete LKM training. Neither behavioral nor imaging analyses supported the hypothesis that altruists’ reduced social discounting reflects effortfully overcoming selfishness. Instead, group differences emerged in social value encoding regions, including rostral ACC and amygdala. Activation in these regions corresponded to the subjective valuation of others’ welfare predicted by the social discounting model. LKM training did not result in more generous behavioral or neural patterns, but only greater perceived difficulty during social discounting. Our results indicate extraordinary altruists’ generosity results from the way regions involved in social decision-making encode the subjective value of others’ welfare. Interventions aimed at promoting generosity may thus succeed to the degree they can increase the subjective valuation of others’ welfare.
