명확한 기중: 선과 악의 기중은 시대에 따라 멠른다
Game Theory and the Shifting Standards of Good and Evil
Our previous essay examined the Jekyll-Hyde duality inherent in human nature. Yet we must dig deeper into a fundamental question: Why do our standards of good and evil shift across time? What determines whether an action is considered virtuous or corrupt?
The answer lies not in abstract philosophy, but in game theory. Standards of good and evil are not unchanging moral absolutes. Rather, they are equilibrium concepts embedded within institutional frameworks. When institutions are strong and functioning well, cooperation and ethical behavior yield the best outcomes. When institutions weaken, selfishness and deception become advantageous.
Nash Equilibrium and the Rules of Morality
Mathematician John Nash revolutionized our understanding of rational behavior through his equilibrium concept. A Nash equilibrium is a situation where no player can improve their outcome by unilaterally changing their strategy, given the strategies of all other players.
Most importantly: Nash equilibrium explains why moral behavior exists without requiring police surveillance. When everyone follows traffic rules at intersections, no individual benefits from breaking them. The system is self-reinforcing. The rule “do not steal” creates a Nash equilibrium when most follow it – everyone benefits from secure property rights.
This insight is profound: Morality is not primarily about virtue. It is about equilibrium stability. Good behavior is “good” because it produces better collective outcomes. Evil behavior is “evil” because it destabilizes the system.
The Prisoner’s Dilemma: Why Evil Has an Advantage
But here lies the dark truth game theory reveals: In the short term, within a stable system, evil often has an advantage.
The Prisoner’s Dilemma demonstrates this perfectly. Two prisoners can either confess or stay silent. Rational analysis shows each should confess regardless of what the other does. Yet if both follow this logic, both suffer worse outcomes than if both had remained silent.
Translated to morality: The person willing to cheat the furthest often gains the most in the short run. A businessman who violates regulations gains competitive advantage over ethical competitors. A politician who ignores norms consolidates power faster than one bound by tradition. The cheater accumulates wealth and influence while the honest person follows unprofitable rules.
This is why moral societies are fragile. They depend on most people restraining themselves from cheating despite having incentive to do so. The system works only through collective commitment to rules that each individual might benefit from violating.
The Balance Point: Where Good and Evil Equilibrate
Societies exist at a precarious balance. There is an equilibrium point where:
- Enough people follow moral rules to maintain the system
- Enough people violate those rules to gain personal advantage
- Institutions remain strong enough to punish egregious violations
- But weak enough that powerful violators can face little consequence
This balance depends on:
- Institutional strength: Can the system punish defection?
- Information clarity: Do people see violations occurring?
- Leadership credibility: Do leaders follow the rules they impose?
- Trust levels: Do citizens believe others will cooperate?
When any of these weakens significantly, the equilibrium shifts dangerously. Defection becomes more attractive. Others observe successful rule-breaking and emulate it. The system unravels.
The Trump Equilibrium: A Test Case
Donald Trump’s political career provides a fascinating test of game theory predictions. Trump’s strategy has been simple: Violate the norms that constrain other politicians. Openly ignore ethics rules. Attack institutions. Enrich family members through political power. Deceive without shame.
Initially, this worked precisely as game theory predicts. By defecting from the moral equilibrium while others remained cooperative, Trump gained massive advantage. He consolidated power, enriched his family, and attracted a political movement.
But what happens as more players observe his success and adopt his strategy? Game theory predicts the equilibrium collapses. When defection becomes widespread, the entire system degrades. Everyone ends up worse off.
The critical question: Are American institutions strong enough to prevent Trump’s defection strategy from becoming contagious? Or has institutional erosion already reached the point where the system cannot contain him?
If institutions hold firm, the Trump equilibrium will be constrained, norms will reassert themselves, and violations will be punished. If institutions have weakened too much, America transitions to a new equilibrium where defection is normalized and ethics are hollowed out.
Conclusion: Morality as Game Theory
Good and evil are not cosmic forces. They are outcomes of game theory operating within institutions. When institutions reward cooperation, cooperation flourishes and we call it “good.” When institutions fail to punish defection, selfishness spreads and we call it “evil.”
The standards of good and evil shift because the game’s payoff matrix shifts when institutions change. What worked as moral equilibrium under strong institutions becomes disadvantageous when those institutions weaken.
America faces a critical choice: Strengthen the institutional guardrails that maintain the cooperative equilibrium, or watch as the system transitions to a defection equilibrium where the rules of the game are rewritten and morality itself is redefined.
The answer will determine not just Trump’s fate, but America’s future.
