A study found that people evaluate others' non-cooperative behavior more based on their personal experience, even if the person has a bad reputation. In contrast, cooperative behavior is generally evaluated positively regardless of reputation or personal experience. The study suggests that people use a combination of reputation and per...
A five-year panel study in Japan found that vaccine-related conspiracy beliefs are associated with media skepticism and distrust of institutions. Common forms of conspiracy thinking involve persistent distrust of social institutions and mainstream media.
Researchers found plastics in 7 of 10 green sea turtles, with macroplastics dominating the diet, and estimated origin of ingested plastics to extend beyond the turtles' migratory range. This study provides evidence for transboundary marine plastic pollution affecting sea turtles.
A new model proposes a tolerant integrated reciprocity strategy that incorporates both personal experience and social reputation to maintain high levels of cooperation even in noisy environments. The study's results demonstrate the effectiveness of this approach in improving cooperation outcomes.
Researchers discovered that gradual, nuanced updates of reputations sustain cooperation through indirect reciprocity. The ternary system allows for justified defection against individuals with bad reputations, rather than degrading the defector's reputation.
A study found people accept AI's judgments on moral decisions when AI judges positive actions and humans judge negative ones. This suggests individuals perceive AI's judgment as more objective, especially when human judgments might be biased.
Researchers identify two robust social norms that protect cooperative behavior from defector invasions and reputation costs. These norms shield justified defection, allowing cooperation to persist, while others negatively evaluate unjustified cooperation, excluding free-riders.
A groundbreaking study found that individuals tend to cooperate even after being defected in social situations, contradicting traditional game theory models. The research suggests that humans are more forgiving and cooperative than previously thought, inspiring a need for revised models of game theory.
A recent study challenges previous theoretical predictions on justified defection, a mechanism that ensures benefits are returned to cooperative individuals. Researchers found that people have a neutral attitude toward justified defection, unlike cooperation with a bad person, which is viewed as good.
A new strategy promotes mutual cooperation by introducing a 'escape interaction' that can deter defection. The study suggests cooperative societies can be maintained without revenge, expanding the field of cooperation research.
A team of researchers analyzed how diverse social norms impact cooperation using game theoretical methods. They found that adopting 'dividualism' leads to the extinction of a norm assessing helpful behavior towards bad individuals, contradicting previous research based on individualism.
Researchers found that non-cooperative norms initially dominate, followed by a norm allowing complex judgment of good and bad behavior. Cooperation then spreads as multiple cooperative norms coexist.
