Why does a player ever sacrifice their own score? Darwin's special difficulty.
Play It
Characterization
Altruism — genuine, costly behaviour that benefits another at a net cost to oneself — presents what Darwin called a "special difficulty" for the theory of natural selection. If evolution selects for individual fitness, why does any organism sacrifice its own reproductive success for another? W. D. Hamilton's theory of kin selection (1964) provided a partial answer: an organism can increase the frequency of its genes by helping relatives, in proportion to their genetic relatedness (Hamilton's rule: rB > C). Robert Trivers's theory of reciprocal altruism (1971) extended the explanation to non-kin: I help you now because you will help me later. Multi-level selection theory, championed by David Sloan Wilson and E. O. Wilson, argues that groups of altruists outcompete groups of selfish individuals. Each framework explains some forms of altruism, but none accounts for the full range of human prosocial behaviour — in particular, costly altruism toward strangers whom one will never meet again, with no audience to observe the act. Anonymous blood donation, disaster relief for distant populations, anonymous charitable giving — these exceed what kin selection, reciprocity, or group selection can predict. The Academy hosts the Origin of Altruism in the Heart School because it is the deepest question about the moral architecture of play: in every cooperative game, the possibility of genuine sacrifice exists, and no evolutionary theory fully explains why anyone takes it.

Quests
The Magus
Propose a novel explanatory framework — or a creative synthesis of existing ones — that could account for anonymous, costly altruism toward strangers who will never reciprocate. Your framework should engage with the limitations of kin selection, reciprocal altruism, and group selection, and explain what they leave unexplained. You may draw on cultural evolution, moral psychology, or any other discipline.
The Adventurer
Perform a genuinely costly act of kindness for a stranger — one that requires real sacrifice of time, money, or comfort, with no expectation of return or recognition. Afterward, write a candid introspective report: What motivated you? Did it feel selfless, or could you detect self-interested motives (warm glow, social signaling, guilt avoidance)? Connect your self-examination to the psychological egoism vs. altruism debate as studied by C. Daniel Batson.
The Sage
Trace the scientific history of altruism as a problem, from Darwin's acknowledgment that self-sacrifice posed a "special difficulty" for natural selection, through Hamilton's kin selection (1964), Trivers's reciprocal altruism (1971), the group selection controversy (D.S. Wilson, E.O. Wilson), to the effective altruism movement. Explain why each theory advanced the conversation and what residual puzzle it left for the next generation.
