Study Notes
Kin Selection and Altruism
- Kin selection favors relatives to increase inclusive fitness, the passing of genes through relatives.
- Altruistic behavior examples include alarm calls in monkeys, where the individual is at risk but benefits relatives, and suicidal bees/ants sacrificing for the colony.
- Hamilton's Rule states that genes for altruism are favored if the benefit to relatives surpasses the cost to self.
- Inclusive fitness, a concept by Richard Dawkins in The Selfish Gene, focuses on gene survival, not only individual survival.
Inclusive Fitness and Kin Detection
- Vervet monkeys use different alarm calls for varied predators, showcasing kin-based social behaviors.
- Modern nepotism, like inheritance and favoritism in law and business, mirrors inclusive fitness by favoring family members.
- Humans use proxies for kinship during childhood: co-residence and maternal association.
- Inbreeding depression occurs in small, isolated groups, leading to harmful genetic effects.
- The Westermarck Effect, prevalent in Kibbutzim, suggests people raised together are less likely to marry.
Reciprocal Altruism and Social Exchange
- Reciprocal altruism involves helping others with the expectation of future reciprocation.
- Examples include reciprocal grooming in animals, blood-sharing among vampire bats, and cooperation in humans.
- Requirements for reciprocal altruism are recognizing partners, maintaining interaction records, and motivation for reciprocation.
- Foragers share resources, especially those with high variance, to uphold social norms.
- Free-rider problems exist, where individuals benefit without contributing.
Human Generosity and Economic Games
- Humans engage in non-reciprocal helping behaviors like tipping and giving directions.
- Situational factors often outweigh personality traits in influencing helping behavior.
- The Dictator Game involves one player dividing a sum with another who has no say. Results show players often offer a portion, reflecting fairness over solely self-interest.
- In the Ultimatum Game, one player proposes a division, with the second player having the power to accept or reject. Offers around 30-70% are frequently accepted, while lower offers are often rejected.
Theories of Generosity: Punishment vs. Mutualistic
- The punishment interpretation suggests that altruistic norms are upheld through punishment, strengthening group cohesion.
- The mutualistic interpretation argues that people choose cooperative partners, leading to genetic selection for fairness as cooperation becomes more beneficial.
Cooperation, Punishment, and Mutualism
- The Prisoner's Dilemma, Dictator Game, and Third-Party Punishment (TPP) demonstrate people often punish defectors, even at personal cost.
- TPP is rare outside modern contexts where it's inexpensive (e.g., calling the police) and raises questions about altruism due to the lack of direct costs to the punisher.
- Economic games have limitations due to unrealistic structures and differences in motivation.
Reputation and Partner-Choice
- Reputation cues, like images of eyes, increase prosocial behavior, suggesting people act more altruistically when observed.
- The Image Management Hypothesis proposes that altruistic behavior is driven by reputation concerns rather than pure altruism.
- Biological Markets involve individuals "choosing" partners who maximize mutual benefit, for example, in cleaner fish relationships.
Dilemmas of Cooperation
- Cooperation presents challenges like limiting personal utility and dealing with free-riders.
- Time-discounting can limit long-term cooperation as future rewards become less valuable.
Economics of Moral Feelings
- Moral feelings can counter time-discounting by serving as immediate rewards.
- Feelings like guilt and loyalty act as commitment devices to sustain cooperation.
- Commitment devices, like engagement rings, public commitments, or bonded businesses, represent costly signals that reduce exploitation.
Friendship and Commitment
- Love stabilizes relationships through public signals, expensive displays, and irrational devotion, making commitment costly to fake.
- Friendship differs from rational exchange; acts are small, incremental, culturally universal, and can fail if one partner exploits the other.
Evolution and Morality
- Morality's non-material nature poses a challenge to evolutionary frameworks.
- Cooperation models explain moral behavior through punishment or self-interest, but the moral imperative itself is less clear.
Moral Psychology
- Intuitions, like feeling something is wrong, often guide moral judgments rather than explicit rules.
- Moral rule vs. convention: Moral rules are seen as universal and inherent, while conventions are situational and variable.
Moral Models
- The consequentialist model suggests actions are moral if they increase overall utility.
- The deontological model emphasizes that actions are moral if they follow specific principles, regardless of outcomes.
- Trolley problems expose the differences in moral intuitions.
Empathy and Social Contract
- Empathy-based morality involves taking the perspectives of others.
- Social contract theory posits that moral behaviors maintain a mutually beneficial social order.
Mutualist Models of Morality
- Mutualist morality promotes fairness as an evolved mechanism, emphasizing just distribution and proportionate punishment.
- This model proposes that morality supports genetic selection by fostering fairness and cooperative behavior.
Moral Foundations
- Haidt's moral foundations include care-harm, fairness, loyalty, authority, and sanctity-purity.
- They explain diverse moral judgments beyond harm and fairness.
Moral Foundations and Politics
- Different moral emphases lead to polarized political views, with certain domains (e.g., sanctity) holding more importance for specific groups.
