The Connection Between Pro-social Behaviour and Altruism

Most of us have helped someone without thinking twice – held a door open, donated to a cause, or comforted a friend in distress. These are all examples of pro-social behaviour: actions that benefit others. But here’s a question worth sitting with – does doing good always mean being selfless? Not necessarily. That’s where the concept of altruism comes in, and understanding the difference between the two is one of the most debated topics in social psychology.

What is pro-social behaviour? 🔗

Pro-social behaviour refers to intentional actions aimed at benefiting others, encompassing activities such as donating, cooperating, assisting, and volunteering. The person carrying out the action may or may not be entirely selfless – what matters is that the outcome benefits someone else. This broad definition includes everything from a neighbour helping with groceries to a corporation funding disaster relief. As researchers Pfattheicher, Nielsen, and Thielmann (2022) note, nearly all definitions of pro-social behaviour share one common thread: an emphasis on promoting the welfare of someone other than the actor.

Importantly, pro-social behaviours can be motivated by a wide range of factors – empathy, concern for others’ rights, social norms, one’s reputation, the expectation of reciprocity, or altruism. This diversity of motivations is precisely why pro-social behaviour and altruism, though closely related, are not the same thing.

The origin of “altruism” as a concept 🔗

The word altruism was not always part of our vocabulary. It was coined in the 19th century by Auguste Comte, the French philosopher and founder of Positivism, as a convenient antithesis to egoism. Derived from the Italian word altrui, meaning “to others” or “of others,” the term was introduced to refer to the totality of other-regarding instincts in humans. Comte believed that an ideal society would be built not on self-interest but on genuine care for others. He introduced the term formally in his System of Positive Polity (1851-1854), where altruism became the central moral ideal of his positivist philosophy.

What makes this origin significant is the moral weight Comte attached to the word. Like the word “sociology” itself, “altruism” was coined by Comte, and he saw it as a scientific and ethical cornerstone – the idea that truly civilised humans are capable of acting for others without self-serving motives.

How researchers define altruism today 🔗

Modern psychology has refined Comte’s broad idea considerably. According to Batson, altruism is motivation to increase another person’s welfare, contrasted with egoism, which is the motivation to increase one’s own welfare. This is not merely a philosophical position – it is a psychological one. The focus is on motivation, not just behaviour. What drives you to act matters as much as the act itself.

Researchers like Pfattheicher et al. (2022) distinguish four types of altruism: psychological (intentionalist) altruism, reproductive (evolutionary) altruism, behavioral (consequentialist) altruism, and preference altruism. This multiplicity reveals why defining altruism precisely is so important – researchers using the term loosely often end up drawing very different conclusions from the same data.

Smith and Mackie (2000) similarly highlight that altruism represents a specific form of motivation to benefit others – one that is genuinely free from self-interest. The key word is specific. Altruism is not just any helpful act; it is a motivated state in which improving someone else’s welfare is the ultimate goal, not a means to something else.

Pro-social behaviour and altruism: related but not the same 🔗

One of the most important insights from social psychology is that there is no one-to-one correspondence between pro-social behaviour and altruism – pro-social behaviour need not be motivated by altruism, and altruistic motivation need not always produce pro-social behaviour. This distinction is crucial.

Consider a simple example: making a charitable donation to reduce your tax liability. The outcome benefits others – a charity receives funds – so it is technically pro-social. But the primary motivation is financial self-interest. Altruistic behaviour is defined by selfless motivation – when there are egoistic motives, however remote, the behaviour is more accurately described as pro-social rather than altruistic. Tax-motivated donations are a clear case: helpful in effect, self-serving in intent.

Similarly, a business executive who makes high-profile donations to improve their public image is engaging in pro-social behaviour – but not altruism. Social recognition and the desire for a positive image can drive helping behaviour, even when it appears generous on the surface. As the research makes clear, the appearance of generosity and genuine altruistic motivation are not always the same thing.

The role of empathy in producing true altruism 🔗

So if not all pro-social behaviour is altruistic, what conditions lead to genuine altruism? A large body of research points to empathy as the key mechanism. Batson’s empathy-altruism hypothesis proposes that feelings of empathy lead to altruistic actions – that humans are more likely to act altruistically when they genuinely empathise with the person in need.

According to Batson’s hypothesis, if someone feels empathy towards another person, they will help them regardless of what they can gain from it. This directly challenges the assumption underlying social exchange theory – the idea that all helpful behaviour is ultimately self-serving. Batson’s experimental research, conducted across dozens of studies from 1978 to 2008, consistently found that participants high in empathic concern helped others even when they had an easy opportunity to walk away without social consequence.

Batson defines altruism as a motivational state with the ultimate goal of increasing another’s welfare – and crucially, both altruistic and egoistic motivations can coexist in the same person in the same moment. This is a key nuance: genuine altruism is possible, but it may be mixed with other motivations, making it difficult to identify cleanly in any given act.

Theories competing with the altruism hypothesis 🔗

Not all researchers are convinced that pure altruism exists. Several alternative explanations account for what looks like selfless behaviour through a self-interested lens.

Social exchange theory 🔗

Social exchange theory argues that seemingly altruistic behaviour benefits the altruist and outweighs the cost they bear – making it, at its core, self-interested. From this view, helping a friend who is struggling is rational because it maintains a relationship that has future value to you. Volunteering builds social capital. Donating enhances your reputation. Every helpful act, under this framework, has a hidden return.

Evolutionary perspectives 🔗

Evolutionary theories such as kin selection and reciprocal altruism propose that altruistic behaviour is ultimately self-serving, as it enhances survival and reproductive success. Helping relatives passes on shared genes; helping others who may later reciprocate improves long-term survival. On this account, what we call “altruism” is biology in disguise.

Negative-state relief 🔗

Another egoistic explanation suggests that people help others primarily to reduce their own distress at witnessing suffering. If seeing someone in pain makes you uncomfortable, helping them relieves your negative emotional state – not just theirs. Batson’s experimental designs specifically aimed to rule this out, using conditions where participants could easily escape the discomforting situation without helping. Even when given easy escape, participants with high empathy continued to help at consistently high rates – which Batson took as evidence that their motivation was genuinely other-directed, not self-relieving.

Why the distinction matters 🔗

Understanding the difference between pro-social behaviour and altruism has real-world implications. If policymakers want to encourage charitable giving, community volunteering, or cooperative behaviour, knowing what motivates people – genuine concern for others versus social reward, reputation, or tax benefits – shapes how those incentives are designed. Both individual characteristics such as educational background and emotional temperament, and situational elements, influence how and why people engage in pro-social behaviour.

There is also a deeper philosophical point. The claim that true altruism does not exist – that people’s motives are never entirely forgetful of self – is difficult to settle empirically, partly because the same behaviour can be interpreted through both altruistic and egoistic frameworks. This is not simply an academic debate. It touches on what we believe about human nature itself: are we fundamentally self-seeking, or are we capable of caring about others as an end in itself?

The weight of evidence from Batson’s research, and from developmental psychology and neuroscience, suggests that empathy-driven altruism is real – even if it is rare, and even if it is sometimes mixed with less noble motives. As Pfattheicher et al. (2022) argue, acknowledging the diversity of pro-social behaviour – rather than collapsing it all under one label – is essential for both good science and a more accurate understanding of why people help each other.

What do you think? When you help someone, do you believe you can ever be entirely free of self-interest – or do you think some egoistic motive always lingers, however small? And does the presence of a mixed motive make a generous act any less meaningful?
