This chapter builds a case for experimentation as the best method to test the empathy-altruism hypothesis against its egoistic alternatives. It also considers limitations of this method. First, cases of heroic helping are offered, and reasons are given why such cases do not provide persuasive evidence for the existence of altruism. The logic of experimentation is then summarized, and the role of experiments in Galilean versus Aristotelian science discussed. Implications of the Aristotelian-Galilean distinction for research on altruism are drawn. Two examples of experiments designed to test the nature of the motivation to help produced by empathic concern are then described. Finally, limitations of experimental research are considered, including the open-set problem, the use of undergraduate samples, research problems for which experiments are not appropriate, and ethical issues.

Empirical Approaches to Altruism
Many philosophers have maintained that altruism is a crucial component of morality, and that people often do behave altruistically. Other philosophers, along with many biologists and social scientists, have claimed that facts about human psychology, or about the evolutionary processes that have shaped human psychology, indicate that no human behavior is genuinely altruistic. Part of this disagreement can be traced to the fact that both philosophers and scientists use the term “altruism” with many quite different meanings. Sections 2, 3 and 4, set out a number of widely used accounts of altruism. One of these, “the standard account”, has been the focus of most of the debate in philosophy over the existence of altruism. Sections 5 and 6, review some of the most important empirical work aimed at determining whether humans can indeed behave altruistically, on the standard account.
1. Some Philosophical Background
2. defining “egoism” and “altruism”—the standard account, 3. altruism and evolution, 4. altruism in the social sciences, 5.1 the social punishment hypothesis, 5.2 the aversive-arousal reduction hypothesis, 5.3 the challenge posed by “self-other merging”, 5.4 have batson’s studies made a convincing case for the existence of altruism in humans, 6. beyond egoism vs. altruism, 7. the bottom line, other internet resources, related entries.
People often behave in ways that benefit others, and they sometimes do this knowing that it will be costly, unpleasant or dangerous. But at least since Plato’s classic discussion in the second Book of the Republic , debate has raged over why people behave in this way. Are their motives really altruistic, or is their behavior ultimately motivated by self-interest? Famously, Hobbes gave this answer:
No man giveth but with intention of good to himself, because gift is voluntary; and of all voluntary acts, the object is to every man his own good; of which, if men see they shall be frustrated, there will be no beginning of benevolence or trust, nor consequently of mutual help. (1651 [1981]: Ch. 15)
Views like Hobbes’ have come to be called egoism , [ 1 ] and this rather depressing conception of human motivation has apparently been favored, in one form or another, by a number of eminent philosophical advocates, including Bentham, J.S. Mill and Nietzsche. [ 2 ] Egoism was also arguably the dominant view about human motivation in the social sciences for much of the twentieth century (Piliavin & Charng 1990: 28; Grant 1997). Dissenting voices, though perhaps fewer in number, have been no less eminent. Butler, Hume, Rousseau, and Adam Smith have all argued that, sometimes at least, human motivation is genuinely altruistic.
Though the issue dividing egoistic and altruistic accounts of human motivation is largely empirical, it is easy to see why philosophers have thought that the competing answers will have important consequences for moral theory. For example, Kant famously argued that a person should act “not from inclination but from duty, and by this would his conduct first acquire true moral worth” (1785 [1949]: Sec. 1, parag. 12). But egoism maintains that all human motivation is ultimately self-interested, and thus people can’t act “from duty” in the way that Kant urged. Thus if egoism is true, Kant’s account would entail that no conduct has “true moral worth”. Additionally, if egoism is true, it would appear to impose a strong constraint on how a moral theory can answer the venerable question “Why should I be moral?” since, as Hobbes clearly saw, the answer will have to ground the motivation to be moral in the agent’s self-interest.
There are related implications for political philosophy. If the egoists are right, then the only way to motivate prosocial behavior is to give people a selfish reason for engaging in such behavior, and this constrains the design of political institutions intended to encourage civic-minded behavior. John Stuart Mill, who was both a utilitarian and an egoist, advocated a variety of manipulative social interventions to engender conformity with utilitarian moral standards from egoistic moral agents. [ 3 ]
It is easy to find philosophers suggesting that altruism is required for morality or that egoism is incompatible with morality—and easier still to find philosophers who claim that other philosophers think this. Here are a few examples culled from a standard reference work that happened to be close at hand:
Moral behavior is, at the most general level, altruistic behavior, motivated by the desire to promote not only our own welfare but the welfare of others. (Rachels 2000: 81) [O]ne central assumption motivating ethical theory in the Analytic tradition is that the function of ethics is to combat the inherent egoism or selfishness of individuals. Indeed, many thinkers define the basic goal of morality as “selflessness” or “altruism”. (W. Schroeder 2000: 396) Philosophers since Socrates worried that humans might be capable of acting only to promote their own self-interest. But if that is all we can do, then it seems morality is impossible. (LaFollette 2000a: 5) [ 4 ]
While the egoism/altruism debate has historically been of great philosophical interest, the issue centrally concerns psychological questions about the nature of human motivation, so it’s no surprise that psychologists have done a great deal of empirical research aimed at determining which view is correct. The psychological literature will be center-stage in section 5 , the longest section in this entry, and in section 6 . But before considering the empirical literature, it is important to be clear on what the debate is about.
Providing definitions for “egoism” and “altruism” is a contentious matter, since these terms have been understood in radically different ways both in philosophy and in the biological and social sciences. In this entry the focus will be on the most widespread interpretation of “egoism” and “altruism”, understood as descriptive claims about human psychology, within philosophy. We’ll call it “the standard account”, versions of which have been offered by numerous authors including Broad (1950), Feinberg (1965 [1999]), Sober and Wilson (1998: Chs. 6 & 7), Rachels (2003: Ch. 6), Joyce (2006: Ch. 1), Kitcher (2010, 2011: Ch. 1), May (2011a), and many others. Not surprisingly, there are minor differences among the accounts provided by these authors, and those differences occasionally provoke disagreement in the literature. But all of them bear a strong family resemblance to the one we’re about to sketch. [ 5 ]
At the end of this section, a different account of altruism proposed in philosophy is briefly discussed. Biological accounts of altruism will be considered in section 3 , and accounts proposed by social scientists will be discussed in section 4 . But our present focus is the standard philosophical account.
As already intimated, while advocates of altruism and of egoism agree that people often help others, they disagree about why they do this. On the standard account, defenders of altruism insist that, sometimes at least, people are motivated by an ultimate desire for the well-being of another person, while defenders of egoism maintain that all ultimate desires are self-interested. This formulation invites questions about (1) what it is for a behavior to be motivated by an ultimate desire , and (2) the distinction between desires that are self-interested and desires for the well-being of others .
The first question, regarding ultimate desires, can be usefully explicated with the help of a familiar account of practical reasoning . [ 6 ] On this account, practical reasoning is a causal process via which a desire and a belief give rise to or sustain another desire. For example, a desire to drink an espresso and a belief that the best place to get an espresso is at the espresso bar on Main Street may cause a desire to go to the espresso bar on Main Street. This desire can then join forces with another belief to generate a third desire, and so on. Sometimes this process will lead to a desire to perform a relatively simple or “basic” action, and that desire, in turn, will cause the agent to perform the basic action without the intervention of any further desires. Desires produced or sustained by this process of practical reasoning are instrumental desires—the agent has them because she thinks that satisfying them will lead to something else that she desires. But not all desires can be instrumental desires. If we are to avoid circularity or an infinite regress there must be some desires that are not produced because the agent thinks that satisfying them will facilitate satisfying some other desire. These desires that are not produced or sustained by practical reasoning are the agent’s ultimate desires, and the objects of ultimate desires—the states of affairs desired—are often said to be desired “for their own sake”. A behavior is motivated by a specific ultimate desire when that desire is part of the practical reasoning process that leads to the behavior.
Although the second question, about the distinction between self-interested desires and desires for the well-being of others, would require an extended discussion in any comprehensive treatment of the debate between egoists and altruists, some rough and ready examples of the distinction will suffice here. [ 7 ] The desires that another person’s life be saved, that another person’s suffering be alleviated, or that another person be happy are paradigm cases of desires for the well-being of others, while desires to experience pleasure, get rich, and become famous are typical examples of self-interested desires. The self-interested desires to experience pleasure and to avoid pain have played an especially prominent role in the debate, since one version of egoism, often called hedonism , maintains that these are our only ultimate desires. Stich et al. (2010) maintain that some desires, like the desire that I myself be the one to alleviate my friend’s suffering, are hard to classify, and conclude that both egoism and altruism are best viewed as somewhat vague. [ 8 ]
Whether or not this is correct, it is clear that there are many desires that are neither self-interested nor desires for the well-being of others. One of the earliest examples was provided by Bishop Joseph Butler (1726 [1887]) who noted that revenge often engenders malevolent desires, like the desire that another person be harmed, which are obviously not desires for the well-being of the that person, and are not self-interested either. [ 9 ] Other examples include the desire that great works of art be preserved and the desire that space exploration be pursued. More interesting for moral theory are the desire to do one’s moral duty, and the desire to obey God’s commandments. If people have ultimate desires like these, then egoism is false. But, of course, the existence of ultimate desires like these would not show that altruism is true. The take-away from such cases is that on the standard account, egoism and altruism might both be mistaken.
Though interpretations of “altruism” in the standard account family predominate in the philosophical literature, some philosophers use the term in a very different way. A paper by Thomas Schramme (2017) provides a clear example.
[A]ltruism need not be reduced to its opposition to egoism. In this chapter, altruism is discussed as a psychological basis for moral conduct more generally, not just in terms of motivations to benefit others. Here altruism stands for the capacity to take the moral point of view and be disposed to act accordingly…. Seen in this way, altruism is a short word for the psychological phenomenon of the internalized pull of morality… (2017: 203–204). Altruism is then basically identical with taking the moral point of view, i.e., an individual appreciation of the normative force of morality. (2017: 209). [ 10 ]
Schramme is, of course, aware that many authors reject “such a close connection of general moral motivation and altruistic motivation” but he maintains that this account of altruism “can certainly be found in the philosophical debate” (2017: 209). Much the same claim is made by Badhwar (1993: 90):
In the moral philosophy of the last two centuries, altruism of one kind or another has typically been regarded as identical with moral concern.
Schramme is surely right that
[t]he fact that we can understand altruism both as referring to moral behavior quite generally and as restricted to a more specific set of helping behaviors may lead to confusion. (2017: 204)
Though some philosophers may believe there is a substantive dispute about which account of altruism is correct, others think that the issue is purely terminological. As noted earlier, the primary concern in this entry is with what this entry dubs the “standard account” of altruism. But in the next two sections a number of accounts are considered that differ both from the standard account and from the account discussed by Schramme and Badhwar.
Readers familiar with some of the popular literature on the evolution of morality that has appeared in the last few decades might suspect that recent work in evolutionary biology has resolved the debate between egoists and altruists. For some readers—and some writers—seem to interpret evolutionary theory as showing that altruism is biologically impossible. If altruistic organisms were somehow to emerge, this literature sometimes suggests, they would lose the competition for survival and reproduction to their selfish conspecifics, and they would quickly become extinct. On this view, any appearance of altruism is simply an illusion. In the memorable words of biologist Michael Ghiselin (1974: 247) “Scratch an ‘altruist’ and watch a ‘hypocrite’ bleed”.
But as Sober and Wilson (1998) have argued with great clarity, there is no simple connection between evolutionary theory and the philosophical debate between egoism and altruism. This is because the concept of altruism that is important in evolutionary theory is quite different from the standard concept of altruism invoked in the philosophical debate. For biologists, an organism behaves altruistically if and only if the behavior in question reduces its own fitness while increasing the fitness of one or more other organisms. Roughly speaking, an organism’s fitness is a measure of how many descendants it will have. [ 11 ] As Sober and Wilson note, on this evolutionary account of altruism, an organism can be altruistic even if it does not have a mind capable of having beliefs and desires. Thus there can be no easy inference from biological altruism to psychological altruism. Nor does the inference go in the opposite direction. To make the point, Sober and Wilson (Ch. 10) note that natural selection might well equip humans or other psychologically sophisticated organisms with ultimate desires to foster the welfare of their offspring under certain circumstances. Organisms with these ultimate desires would be psychological altruists, though the behavior that the desires gave rise to would typically not be evolutionarily altruistic, since by helping their offspring organisms typically are increasing their own fitness. So, contrary to the presumption that evolutionary biology has resolved the debate between egoists and altruists in favor of egoism, it appears that evolutionary theory little to offer that will support that conclusion. [ 12 ]
In recent decades there has been an enormous amount of discussion of altruism in psychology, sociology, economics, anthropology and primatology. Much of the work in psychology, including all of the work recounted in section 5 , has adopted the “standard account” of altruism. But some psychologists, and many researchers in other disciplines, have something very different in mind. In a useful review of recent discussions of altruism, Clavien and Chapuisat lament the fact that
[t]he notion of altruism has become so plastic that it is often hard to understand what is really meant by the authors using the term, and even harder to evaluate the degree to which results from one research field—e.g., experimental economics—may facilitate the resolution of debates in another research field—e.g., evolutionary biology or philosophy. (2013: 134)
One of the notions that Clavien and Chapuisat find playing a role in evolutionary anthropology, evolutionary game theory and experimental economics is what they call “preference altruism”. “An action is altruistic”, in this sense, “if it results from preferences for improving others’ interests and welfare at some cost to oneself” (2013: 131). Though the agent’s psychology is relevant, on this account of altruism, there is no mention of the agent’s ultimate desires. Thus an action can be preference altruistic even if the agent’s preference for improving someone else’s welfare is an instrumental preference engendered by the belief that improving the recipient’s welfare will contribute to the agent’s own pleasure or treasure.
A second, quite different, concept of altruism invoked in these disciplines is what Clavien and Chapuisat call “behavioral altruism”. On this interpretation of altruism, an agent’s psychology plays no role in determining whether her action is altruistic.
A behavior is altruistic if it brings any kind of benefit to other individuals at some cost for the agent, and if there is no foreseeable way for the agent to reap compensatory benefits from her behavior. (2013: 131)
Ramsey (2016) makes a plausible case that some eminent primatologists and psychologists (including de Waal (2008) and Warneken and Tomasello (2008)) invoke an even less demanding account of altruism, one that requires that the recipient benefit but drops the requirement that altruistic behavior must involve some cost to the agent. Ramsey labels this notion “helping altruism”.
Combining accounts from philosophy, biology and the social sciences, Piccinini and Schulz (2019) offer a multidimensional taxonomy for different accounts of altruism, and argue that the distinctions they draw are essential for assessing the moral status of different kinds of altruism.
In reviewing the many different ways in which the term “altruism” has been used in the empirical and philosophical literature, it is hard to resist allusions to the biblical Tower of Babel. But for the remainder of this entry, these interpretations of “altruism” will be left behind. From here on, the focus will be on altruism as it is understood in the standard account.
5. The Egoism vs. Altruism Debate in Psychology
The psychological literature relevant to the egoism vs. altruism debate is vast; [ 13 ] in the interests of a tolerable brevity, the entry will focus on the work of Daniel Batson and his associates, who have done some of the most influential and philosophically sophisticated work in this area.
Batson, along with many other researchers, begins by borrowing an idea that has deep roots in philosophical discussions of altruism. Though the details and the terminology differ significantly from author to author, the core idea is that altruism is often the product of an emotional response to the distress of another person. Aquinas (1270 [1917]: II–II, 30, 3), for example, maintains that
mercy is the heartfelt sympathy for another’s distress, impelling us to succour him if we can.
And Adam Smith (1759 [1853]: I, I, 1. 1) tells us that
pity or compassion [is] the emotion we feel for the misery of others, when we either see it, or are made to conceive it in a very lively manner
and these emotions
interest [man] in the fortunes of others, and render their happiness necessary to him, though he derives nothing from it except the pleasure of seeing it.
Batson (1991: 58) labels this response “empathy” which he characterizes as “an other-oriented emotional reaction to seeing someone suffer”, and calls the traditional idea that empathy leads to altruism the empathy-altruism hypothesis. On Batson’s account (1991: 86), empathy
includes feeling sympathetic, compassionate, warm, softhearted, tender, and the like, and according to the empathy-altruism hypothesis, it evokes altruistic motivation
though that motivation does not always lead to behavior. Batson (1991: 117) contrasts empathy with a cluster of affective responses he calls “personal distress” which is “made up of more self-oriented feelings such as upset, alarm, anxiety, and distress”. [ 14 ]
If the philosophical tradition that suggests the empathy-altruism hypothesis is on the right track, and Batson believes it is, one would predict that when people feel empathy they will desire to help those who evoke the emotion, and thus be more inclined to engage in helping behavior than people who do not feel empathy. This does not mean that people will always engage in helping behavior when they feel empathy, since people may often have conflicting desires, and not all conflicts are resolved in favor of empathy’s urgings. Nor does it mean that when people feel little or no empathy they will not engage in helping behavior, since the desire to help can also be produced by a variety of processes in which empathy plays no role. But we should expect that typically people feeling empathy will be more likely to help than people who aren’t feeling empathy, and the stronger their feelings of empathy the more likely it is that they will engage in helping behavior.
In order to put this claim to empirical test, it is important to have ways of inducing empathy in the laboratory, and there is a substantial body of literature suggesting how this can be done. For example, Stotland (1969) showed that subjects who were instructed to imagine how a specified person (often called “the target”) felt when undergoing what subjects believed to be a painful medical procedure reported stronger feelings of empathy and showed greater physiological arousal than subjects who were instructed to watch the target person’s movements. [ 15 ] Relatedly, Krebs (1975) demonstrated that subjects who observe someone similar to themselves undergo painful experiences show more physiological arousal, report identifying with the target more strongly, and report feeling worse while waiting for the painful stimulus to begin than do subjects who observe the same painful experiences administered to someone who is not similar to themselves. Krebs also showed that subjects are more willing to help at some personal cost when the sufferer is similar to themselves. Batson (1991: 82–87) interprets these findings as indicating that people are more inclined to feel empathy for those they believe to be similar to themselves, and thus that empathy can often be induced by providing a person with evidence that she and a target person are similar.
To make the case that empathy leads to helping behavior, Batson relies in part on work by others, including the just-cited Krebs (1975) study and a study by Dovidio et al. (1990). In that latter study, Stotland’s technique for manipulating empathy by instructing subjects to take the perspective of the person in distress was used to induce empathy for a young woman. Subjects focused on one of two quite different problems that the young woman faced. When given an opportunity to help the young woman, subjects in whom empathy had been evoked were more likely to help than subjects in a low empathy condition, and the increase in helping was specific to the problem that had evoked the empathy.
Many of Batson’s own experiments, some of which are described below, also support the contention that both spontaneously evoked empathy and empathy engendering experimental manipulations increase the likelihood of helping behavior. Another important source of support for the link between empathy and helping behavior is a meta-analysis of a large body of experimental literature by Eisenberg and Miller (1987) which found positive correlations between empathy and prosocial behavior in studies using a variety of techniques to assess empathy. On the basis of these and other findings, Batson (1991: 95) argues that
there is indeed an empathy-helping relationship; feeling empathy for a person in need increases the likelihood of helping to relieve that need.
It might be thought that establishing a causal link between empathy and helping behavior would be bad news for egoism. But, as Batson makes clear, the fact that empathy leads to helping behavior does not resolve the dispute between egoism and altruism, since it does not address the nature of the motivation for the helping behavior that empathy evokes. One possibility is that empathy does indeed cause a genuinely altruistic desire to help—an ultimate desire for the well-being of the sufferer. But there are also a variety of egoistic routes by which empathy might lead to helping behavior. Perhaps the most obvious of these is that empathy might simply be (or cause) an unpleasant experience, and that people are motivated to help because they believe this is the best way to stop the unpleasant experience that is caused by someone else’s distress.
Quite a different family of egoistic possibilities focus on the rewards to be expected for helping and/or the punishments to be expected for withholding assistance. If people believe that others will reward or sanction them for helping or failing to help in certain circumstances, and that the feeling of empathy marks those cases in which social sanctions or rewards are most likely, then we would expect people to be more helpful when they feel empathy, even if their ultimate motivation is purely egoistic. A variation on this theme focuses on rewards or punishments that are self-administered. If people believe that helping may make them feel good, or that failing to help may make them feel bad, and that these feelings will be most likely to occur in cases where they feel empathy, then once again we would expect people who empathize to be more helpful, though their motives may be not at all altruistic.
During the last four decades, Batson and his collaborators have systematically explored these egoistic hypotheses and many others. Their strategy is to design experiments in which the altruistic explanation of the link between empathy and helping can be compared to one or another specific egoistic explanation. Reviewing all of these experiments would require a far longer entry. [ 16 ] Instead the focus will be on two clusters of experiments that illustrate the potential philosophical rewards of designing and interpreting experiments in this area, as well as some difficulties with the project.
One of the more popular egoist alternatives to the empathy-altruism hypothesis is the idea that people engage in helping behavior because they fear that other people will punish them if they do not. If I don’t help, the actor is supposed to worry, people will be angry or they will think badly of me, and this may have negative effects on how they treat me in the future. As it stands, this egoist hypothesis can’t explain the fact that empathy increases the likelihood of helping, but a more sophisticated version is easy to construct by adding the assumption that people think social sanctions for not helping are more likely when the target engenders empathy.
To test this hypothesis—which Batson calls the socially administered empathy-specific punishment hypothesis —against the empathy-altruism hypothesis, Batson and his associates (Fultz et al. 1986) designed an experiment in which they manipulated both the level of empathy that subjects felt for the target and the likelihood that anyone would know whether or not the subject had opted to help a person in need. Others can form a negative evaluation of your decision not to help only if they know the choice you are facing and the decision you have made; if your decision is secret, you need have no fear of social sanctions. Thus the socially administered empathy-specific punishment hypothesis predicts that subjects who exhibit high empathy on a given occasion will be more likely to help when they believe others will know if they fail to do so. On the empathy-altruism hypothesis, by contrast, high empathy subjects are motivated by an ultimate desire to help, and thus their helping levels should be high whether or not others would know if they decided not to help. In the low empathy condition, both hypotheses predict that levels of helping will be low. These predictions are summarized in Tables 1 and 2.

Altruism as a phenomenon is located at the intersection of several disciplines. It is a topic of inquiry by philosophers and theologians, and it is an object of investigation by social, behavioral, and biological scientists. Neuroscience, psychology, sociology, ethnography, and anthropology have altruism in their sights.
