Altruism
Altruism is concern for the well-being, the life, of others, independently of personal benefit or reciprocity.
The word altruism was popularised by the French philosopher Auguste Comte in French, as altruisme,
as an antonym of egoism. He derived it from the Italian altrui, which in turn was derived from Latin alteri, meaning "other people" or "somebody else". Altruism may be considered a synonym of selflessness, the opposite of self-centeredness.
Altruism is an important moral value in many cultures, ideologies, and religions. It can expand beyond care for humans to include consideration for other sentient beings and future generations.
Altruism in biology, as observed in populations of organisms, is when an individual performs an action at a cost to itself that benefits, directly or indirectly, another individual, without the expectation of reciprocity or compensation for that action.
The theory of psychological egoism suggests that no act of sharing, helping, or sacrificing can be "truly" altruistic, as the actor may receive an intrinsic reward in the form of personal gratification. The validity of this argument depends on whether such intrinsic rewards qualify as "benefits".
The term altruism can also refer to a deontological ethical doctrine that claims that individuals are morally obliged to benefit others. Used in this sense, it is usually contrasted with deontological egoism, which claims individuals are morally obligated to serve themselves first.
Effective altruism is the use of evidence and reason to determine the most effective ways to benefit others.
The notion of altruism
The concept of altruism has a history in philosophical and ethical thought. The term was coined in the 19th century by the founding sociologist and philosopher of science Auguste Comte, and has become a major topic for psychologists, evolutionary biologists, and ethologists. Whilst ideas about altruism from one field can affect the other fields, the different methods and focuses of these fields always lead to different perspectives on altruism. In simple terms, altruism is caring about the welfare of other people and acting to help them, above oneself.Cross-cultural perspectives on altruism
Cross-cultural perspectives on altruism show that how we view and experience helping others depends heavily on where we come from. In individualistic cultures, like many Western countries, acts of altruism often bring personal joy and satisfaction, as they align with values that emphasize individual achievement and self-fulfillment. On the other hand, in collectivist cultures, common in many Eastern societies, altruism is often seen as a responsibility to the group rather than a personal choice. This difference means that people in collectivist cultures might not feel the same personal happiness from helping others, as the act is more about fulfilling social obligations. Ultimately, these variations highlight how deeply cultural norms shape the way we approach and experience altruism.Scientific viewpoints

's essay The Gift contains a passage called "Note on alms". This note describes the evolution of the notion of alms from the notion of sacrifice. In it, he writes:Evolutionary explanations
In ethology, and more generally in the study of social evolution, altruism refers to behavior by an individual that increases the fitness of another individual while decreasing the fitness of the actor. In evolutionary psychology this term may be applied to a wide range of human behaviors such as charity, emergency aid, help to coalition partners, tipping, courtship gifts, production of public goods, and environmentalism.The need for an explanation of altruistic behavior that is compatible with evolutionary origins has driven the development of new theories. Two related strands of research on altruism have emerged from traditional evolutionary analyses and evolutionary game theory: a mathematical model and analysis of behavioral strategies.
Some of the proposed mechanisms are:
- Kin selection. That animals and humans are more altruistic towards close kin than to distant kin and non-kin has been confirmed in numerous studies across many different cultures. Even subtle cues indicating kinship may unconsciously increase altruistic behavior. One kinship cue is facial resemblance. One study found that slightly altering photographs to resemble the faces of study participants more closely increased the trust the participants expressed regarding depicted persons. Another cue is having the same family name, especially if rare, which has been found to increase helpful behavior. Another study found more cooperative behavior, the greater the number of perceived kin in a group. Using kinship terms in political speeches increased audience agreement with the speaker in one study. This effect was powerful for firstborns, who are typically close to their families.
- Vested interests. People are likely to suffer if their friends, allies and those from similar social ingroups suffer or disappear. Helping such group members may, therefore, also benefit the altruist. Making ingroup membership more noticeable increases cooperativeness. Extreme self-sacrifice towards the ingroup may be adaptive if a hostile outgroup threatens the entire ingroup.
- Reciprocal altruism. See also Reciprocity.
- * Direct reciprocity. Research shows that it can be beneficial to help others if there is a chance that they will reciprocate the help. The effective tit for tat strategy is one game theoretic example. Many people seem to be following a similar strategy by cooperating if and only if others cooperate in return.
- *:One consequence is that people are more cooperative with one another if they are more likely to interact again in the future. People tend to be less cooperative if they perceive that the frequency of helpers in the population is lower. They tend to help less if they see non-cooperativeness by others, and this effect tends to be stronger than the opposite effect of seeing cooperative behaviors. Simply changing the cooperative framing of a proposal may increase cooperativeness, such as calling it a "Community Game" instead of a "Wall Street Game".
- *:A tendency towards reciprocity implies that people feel obligated to respond if someone helps them. This has been used by charities that give small gifts to potential donors hoping to induce reciprocity. Another method is to announce publicly that someone has given a large donation. The tendency to reciprocate can even generalize, so people become more helpful toward others after being helped. On the other hand, people will avoid or even retaliate against those perceived not to be cooperating. People sometimes mistakenly fail to help when they intended to, or their helping may not be noticed, which may cause unintended conflicts. As such, it may be an optimal strategy to be slightly forgiving of and have a slightly generous interpretation of non-cooperation.
- *:People are more likely to cooperate on a task if they can communicate with one another first. This may be due to better cooperativeness assessments or promises exchange. They are more cooperative if they can gradually build trust instead of being asked to give extensive help immediately. Direct reciprocity and cooperation in a group can be increased by changing the focus and incentives from intra-group competition to larger-scale competitions, such as between groups or against the general population. Thus, giving grades and promotions based only on an individual's performance relative to a small local group, as is common, may reduce cooperative behaviors in the group.
- * Indirect reciprocity. Because people avoid poor reciprocators and cheaters, a person's reputation is important. A person esteemed for their reciprocity is more likely to receive assistance, even from individuals they have not directly interacted with before.
- * Strong reciprocity. This form of reciprocity is expressed by people who invest more resources in cooperation and punishment than what is deemed optimal based on established theories of altruism.
- * Pseudo-reciprocity. An organism behaves altruistically and the recipient does not reciprocate but has an increased chance of acting in a way that is selfish but also as a byproduct benefits the altruist.
- Costly signaling and the handicap principle. Altruism, by diverting resources from the altruist, can act as an "honest signal" of available resources and the skills to acquire them. This may signal to others that the altruist is a valuable potential partner. It may also signal interactive and cooperative intentions, since someone who does not expect to interact further in the future gains nothing from such costly signaling. While it's uncertain if costly signaling can predict long-term cooperative traits, people tend to trust helpers more. Costly signaling loses its value when everyone shares identical traits, resources, and cooperative intentions, but it gains significance as population variability in these aspects increases.
- Group selection. It has controversially been argued by some evolutionary scientists such as David Sloan Wilson that natural selection can act at the level of non-kin groups to produce adaptations that benefit a non-kin group, even if these adaptations are detrimental at the individual level. Thus, while altruistic persons may under some circumstances be outcompeted by less altruistic persons at the individual level, according to group selection theory, the opposite may occur at the group level where groups consisting of the more altruistic persons may outcompete groups consisting of the less altruistic persons. Such altruism may only extend to ingroup members while directing prejudice and antagonism against outgroup members. Many other evolutionary scientists have criticized group selection theory.
The benefits for the altruist may be increased, and the costs reduced by being more altruistic towards certain groups. Research has found that people are more altruistic to kin than to no-kin, to friends than strangers, to those attractive than to those unattractive, to non-competitors than competitors, and to members in-groups than to members of out-groups.
The study of altruism was the initial impetus behind George R. Price's development of the Price equation, a mathematical equation used to study genetic evolution. An interesting example of altruism is found in the cellular slime moulds, such as Dictyostelium mucoroides. These protists live as individual amoebae until starved, at which point they aggregate and form a multicellular fruiting body in which some cells sacrifice themselves to promote the survival of other cells in the fruiting body.
Selective investment theory proposes that close social bonds, and associated emotional, cognitive, and neurohormonal mechanisms, evolved to facilitate long-term, high-cost altruism between those closely depending on one another for survival and reproductive success.
Such cooperative behaviors have sometimes been seen as arguments for left-wing politics, for example, by the Russian zoologist and anarchist Peter Kropotkin in his 1902 book Mutual Aid: A Factor of Evolution and moral philosopher Peter Singer in his book A Darwinian Left.
