During spring of 2020, environmental ethics students at a medium sized metropolitan university in the Southeastern United States were asked to read and comment on classic essays from Robert Heilbroner and Garrett Hardin, essays regarding our responsibilities towards future generations. In general, students seemed to hold more with Heilbroner’s stance, which left room for compassion, while condemning Hardin’s harshness. Students were then asked to provide written responses stating whether they would personally sacrifice their eventual retirement in order to stop COVID-19 (...) and the reasons for their views. Responses were analyzed and categorized to detect inconsistencies between students’ described views and their willingness to personally sacrifice for the sake of others. Almost 72% of respondents asserted that they would be willing to intervene to stop the novel coronavirus by sacrificing their retirement. A fair number of respondents that stated they would sacrifice said that they would do so because they would benefit personally from the avoidance of guilt and/or from the opportunity to feel good about themselves, suggesting that even seemingly selfless behaviors are sometimes driven by egoistic motivations. Forty percent of all respondents held inconsistent views. Most notably, a number of students condemned Hardin for his lack of compassion, yet were not willing to act compassionately themselves.

Numerous studies show that humans tend to be more cooperative than expected given the assumption that they are rational maximizers of personal gain. As a result, theoreticians have proposed elaborated formal representations of human decision-making, in which utility functions including “altruistic” or “moral” preferences replace the purely self-oriented "Homo economicus" function. Here we review mathematical approaches that provide insights into the mathematical stability of alternative ways of representing human decision-making in social contexts. Candidate utility functions may be evaluated with help (...) of game theory, classical modeling of social evolution that focuses on behavioral strategies, and modeling of social evolution that focuses directly on utility functions. We present the advantages of the latter form of investigation and discuss one surprisingly precise result: “Homo economicus” as well as “altruistic” utility functions are less stable than a function containing a preference for the golden rule or for the common welfare that is only expressed in social contexts composed of individuals with similar preferences. We discuss the contribution of mathematical models to our understanding of human other-oriented behavior, with a focus on the classical debate over psychological altruism. We conclude that human can be psychologically altruistic, but that psychological altruism evolved because it was generally expressed towards individuals that contributed to the actor’s fitness, such as own children, romantic partners and long term reciprocators.
