In economic games, groups where members can punish others for not contributing to the collective good quickly establish strong cooperative norms and thrive. In contrast, groups without a punishment mechanism collapse as individuals act in their own self-interest, causing members to ultimately migrate to the more successful, punishing society.

Focusing on individual performance metrics can be counterproductive. As seen in the "super chicken" experiment, top individual performers often succeed by suppressing others. This lowers team collaboration and harms long-term group output, which can be up to 160% more productive than a group of siloed high-achievers.

Humans evolved to cooperate via reciprocity—sharing resources expecting future return. To prevent exploitation, we also evolved a strong instinct to identify and punish "freeloaders." This creates a fundamental tension with social welfare systems that can be perceived as enabling non-contribution.

In variations of Stanley Milgram's obedience experiments, the presence of nonconformists, or "principled deviants," dramatically reduced the group's willingness to inflict harm. These outsiders model ethical behavior, reining in the cruelty of others and guiding the group toward a better moral outcome.

Our primary aversion is not to inequality itself, but to the perception of unfairness—specifically, when someone is rewarded without contributing their fair share. This "freeloader alert" is a deeply ingrained evolutionary mechanism for enforcing cooperation in social groups.

Love is a powerful motivator within families and small groups. However, at a societal scale, it fails. A society that expects love to scale, like communism, inevitably resorts to force when that expectation is not met. Money, via markets, is the only scalable, non-coercive alternative.

Human intelligence evolved not just for Machiavellian competition but for collaboration. When groups compete—whether ancient tribes, sports teams, or companies—the one that fosters internal kindness, trust, and information sharing will consistently outperform groups of self-interested individuals.

Human societies are not innately egalitarian; they are innately hierarchical. Egalitarianism emerged as a social technology in hunter-gatherer groups, using tools like gossip and ostracism to collectively suppress dominant 'alpha' individuals who threatened group cohesion.

Status-seeking is often a zero-sum game rooted in signaling dominance. True wealth creation is a non-zero-sum, cooperative process. Communities that prioritize cooperation build lasting wealth, while those focused on status signals often remain less prosperous.

Generosity towards employees and customers is more than just good ethics; it's a strategic move in the iterated game of business. It signals your intent to cooperate, which encourages reciprocal cooperation from others. This builds trust and leads to superior long-term outcomes versus a defect-first approach.

Society functions because humans cooperate based on shared beliefs like values or religion. These systems act as a shorthand for trust and alignment, allowing cooperation between strangers. This makes the erosion of a common value set the most significant threat to societal cohesion.
