Rational agents have evolutionary and game-theoretic incentives to act morally.

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that rational agents have evolutionary and game-theoretic incentives to act morally?

Yes. Evolutionary game theory and contractualist models demonstrate that rational agents often have clear incentives to develop moral and cooperative behaviors.

The analysis

The retrieved literature consistently supports the claim that evolutionary and game-theoretic mechanisms (such as assortative matching, direct reciprocity, institutional incentives, and contractualist decision-making) can favor the emergence and stability of moral and cooperative behavior among rational agents. Multiple papers provide formal modeling and empirical support showing how cooperation and fairness evolve rather than merely being altruistic anomalies.
