Cooperation

Lore & Background

Cooperation takes place when a group of organisms works or acts together for a collective benefit to the group, as opposed to working in competition for selfish individual benefit. In biology, many animal and plant species cooperate both with other members of their own species and with members of other species with whom they have symbiotic or mutualistic relationships. Among humans, cooperation occurs for reasons including immediate benefit, genetic relatedness, reciprocity, honesty signaling, cultural group selection, and cultural evolution. Language allows humans to cooperate on a very large scale.

Studies have suggested that fairness affects human cooperation; individuals are willing to punish at their own cost (altruistic punishment) if they believe they are being treated unfairly. An experiment using MRI while playing an ultimatum game found that responders refused unfair offers from human partners at a significantly higher rate than those from a computer partner, and that altruistic punishment is associated with negative emotions generated in unfair situations by the anterior insula of the brain. Image scoring, where a participant learns of a counterpart's prior behavior or reputation, promotes cooperative behavior in situations where direct reciprocity is unlikely. Many organisms other than apes, such as fish, birds, and insects, exhibit cooperative behavior including teaching, helping, and self-sacrifice, and can coordinate to solve problems.

The author Nichola Raihani argues that Earth is a history of teamwork, collective action, and cooperation, and that working together yields success, especially within families. Democracy was created because of three key traits: social comparison, engagement with collaboration, and wanting to be someone who shares, stemming from the desire to not monopolize resources. When clients observe a current interaction reacting badly, others may stop watching or go elsewhere, leading to better service when clients can be made aware of cooperative ability. This has been observed in generosity tournaments among people and among cleaner fish.

Every human achievement relies on cooperation efforts created by others. Humans are biologically geared to ensuring survival by social instincts; early humans hunted or gathered food cooperatively, and raising children required essential food. Kin selection or inclusive fitness theory is defined as a reproductive strategy that favors the success of an organism's relatives, even when not in the organism's own best interest, and is highly relevant to human social behavior. In Alfred Adler's individual psychology, social instinct is an innate drive for cooperation that leads individuals to inculcate social interest and the common good.

Reader's Guide

Cooperation is a central concept across biology, psychology, and sociology, describing how organisms work together for collective benefit. Kin selection is a specific form where animals help rear relatives' offspring to enhance their own fitness, supported by theories such as 'pay-to-stay' and 'territory inheritance,' both valid in cichlid fish. Studies on red wolves show that delayed dispersal and helping others rear offspring can extend male wolves' life spans, indicating both short-term and long-term benefits. Kin discrimination, where species provide more help to closer relatives, has been documented in species like the Western bluebird, Pied kingfisher, Australian magpie, and Dwarf Mongoose.

Cooperative systems as processes where components work together to achieve global properties, leading to emergence—a greater-than-the-sum-of-its-parts outcome. Examples include cells in an organism, neurons creating thought, organisms forming ecosystems, and people forming families and nations. Understanding the mechanisms that create cooperating agents is noted as one of the most important and least well understood phenomena. The article preserves uncertainty about the complexity of cooperation, noting that some researchers assert helpers may receive more direct gains than commonly reported and that cooperation may be part of broader population unification.
