Let me tell you something uncomfortable: the most generous person you know — the one who volunteers every weekend, donates quietly, never asks for anything in return — is probably getting something out of it. Not money. Maybe not even recognition. But something. A feeling. A status. A story they tell themselves at 11pm before sleep. And that is not an insult. It is just biology.

Welcome to the science of selfishness — the most honest conversation we are probably too polite to have.

Start Here: What the Research Actually Says

Evolutionary biology has a term for it: inclusive fitness. First articulated by biologist W.D. Hamilton in 1964, the theory suggests that organisms — including humans — are wired to act in ways that maximise the survival of their own genes. Not necessarily themselves as individuals, but their genetic interests. Which is why you would run into a burning building for your child before you would for a neighbour’s child. It is not cruelty. It is code.

Psychologist Abraham Maslow built an entire framework around this truth. His hierarchy of needs, published in 1943, begins — and must begin — with self. Physiological needs. Safety. Before love, before community, before purpose. You cannot share oxygen you do not have.

A 2012 study published in the journal Psychological Science found that self-interest is the single strongest predictor of human decision-making — stronger than ideology, social pressure, or even moral conviction. In other words: when it is abstract, we are idealists. When it is personal, we are strategists.

A Gallup study found that only about 3% of the global population gives 10% or more of their income to charity consistently. Three percent. Even among the generous, full selflessness is statistically rare.

“Man is not, by nature, deserving of all that he wants. When we think that we are automatically entitled to something, that is when we start walking all over others to get it.”

What Does God Have to Do With It?

Here is where it gets theologically spicy.

The Bible does not pretend that humans are naturally good. In Jeremiah 17:9, it says, “The heart is deceitful above all things, and desperately sick; who can understand it?” That is not pastoral comfort — that is a clinical observation. The very architecture of the Fall in Genesis 3 is a story of self-interest: Eve wanted wisdom for herself, Adam followed suit, and when God came looking, they both pointed fingers. Sound familiar?

And yet, the same scripture commands in Matthew 22:39: “Love your neighbour as yourself.” Not instead of yourself. As yourself. Which means the self-love is assumed — it is the baseline, the benchmark. You are not commanded to deny your self-interest entirely; you are invited to extend it outward.

So was man created selfish? Perhaps the more honest answer is: man was created with self-preservation instincts, in a fallen world, and selfishness is what happens when those instincts go unchecked. The Bible does not celebrate selfishness — but it acknowledges it with a honesty that modern motivational culture rarely does.

The “Selfless” People — A Closer Look

Let us talk about altruism, because it deserves honest scrutiny.

In 1975, sociobiologist E.O. Wilson argued in Sociobiology: The New Synthesis that truly selfless acts are evolutionary anomalies. What we call altruism, he suggested, is almost always reciprocal — we give because we expect return, even if unconsciously. Scientists call it reciprocal altruism. The street calls it “keeping score.”

Consider the Lagos philanthropist who funds a community borehole. Noble? Absolutely. But notice: there is usually a plaque. His name on it. His photo at the commissioning. There is a kind of social currency — reputation capital — that generosity buys. Neuroscience confirms it: MRI studies show that charitable giving activates the brain’s reward centres — the same ones triggered by food, sex, and money. Virtue, it turns out, feels good. Which means we might be pursuing it partly because of how it feels.

That does not make generosity fake. It makes it human. But it does complicate the halo we place on “selfless” people. Their motivations may become clearer only in time — when the relationship sours, when the recognition disappears, when the plaque gets repainted.

So Why Do We Have Laws?

Because without them, your neighbour would help himself to your generator. Probably at 2am.

The entire architecture of law and governance is built on a frank admission: left unchecked, self-interest produces chaos. Thomas Hobbes, writing in Leviathan in 1651, described the natural state of man — without social contracts — as “solitary, poor, nasty, brutish, and short.” Three hundred and seventy years later, watch five minutes of Lagos traffic without enforceable lane discipline and you will understand exactly what Hobbes meant.

Laws do not change human nature. They manage it. Speed limits exist because, unregulated, people drive as fast as they feel comfortable. Tax law exists because, unregulated, very few people would voluntarily fund public infrastructure. Employment contracts exist because goodwill has a shelf life. The rule of law is society’s polite acknowledgment that we are all, at some level, negotiating self-interest — and we need referees.

“The first duty of a man is to think for himself.”
— José Martí

What This Means for the Family

The family is the first community — and selfishness is the first crisis it faces.

Ask any marriage counsellor what kills relationships. They will not say different love languages or incompatible schedules. They will say: unmanaged self-interest. He wants peace; she wants to be heard. He wants to save; she wants to experience. He wants to be appreciated; she wants to be understood. Both legitimate. Both, at their worst, weaponised.

Children are the most honest humans alive precisely because they have not yet learned to disguise their self-interest. A toddler who grabs a toy without apology is not a bad child — he is a very transparent adult-in-training. Parenting, at its core, is the long, loving project of teaching a selfish creature to share. And yet we grow up, put on suits, and pretend the project is complete.

A family that does not acknowledge the self-interest of each member does not become selfless — it becomes dishonest. The most functional families are those that create structures — roles, conversations, traditions, expectations — that channel individual self-interest toward collective wellbeing. Daddy still wants to be respected. Mummy still needs to feel seen. The children still want autonomy. Good families negotiate all of this without pretending it does not exist.

What This Means for the Community

Zoom out from the family, and the math gets harder.

A community of hundreds or thousands of self-interested people requires more than goodwill — it requires systems. Community development does not happen because everyone woke up selfless one morning. It happens because incentives were aligned. The market trader keeps the front of his shop clean not primarily for beautification but because a dirty front drives away customers. The politician builds roads before elections. The landlord fixes the roof when vacancy looms.

This is not cynicism — it is design. The best communities are not those populated by saints but those that build systems smart enough to make self-interest serve the collective. Lagos’s most functional estates are those with functioning residents’ associations — not because the residents became altruistic, but because the association made individual compliance individually beneficial.

How Do We Navigate This? Practical Steps

1. Name your self-interest honestly.

Before you say “I am doing this for the team,” pause. Ask yourself what you are also getting from it. There is no shame in the answer — only clarity. Self-awareness is the beginning of emotional intelligence.

2. Build structures, not just goodwill.

Whether in your business, your marriage, or your community, do not rely on people’s good intentions as your primary risk management strategy. Create agreements. Roles. Accountability. Good systems are what goodwill looks like when it grows up.

3. Look for the overlap.

The most effective leaders, parents, and community builders are not those who suppress self-interest — they are those who find where individual interests naturally converge. If the community winning also means you win, you will not need a sermon. You will need a strategy.

4. Cultivate the practice of delayed self-interest.

The most sophisticated form of self-interest is long-term. The parent who sacrifices now invests in a child who will carry them later. The leader who builds others’ capacity earns loyalty that outlasts authority. Generosity with a long time horizon is still self-interest — but it is the kind that builds civilisations.

5. Choose your community deliberately.

Because self-interest is contagious. Surround yourself with people whose self-interest happens to align with yours — and with your growth. A room full of people investing in their own development will pull you forward. A room full of people protecting their own mediocrity will pull you back. Both are just self-interest at work.

Here is the final uncomfortable truth: selfishness is not the enemy of community — unexamined selfishness is. The goal has never been to eradicate the self. The invitation — from science, from scripture, from every functioning society we can point to — is to understand it deeply enough to direct it wisely.

We were wired for me. The work is learning how to make “me” make room for “we.”

And honestly? That is the most human thing of all.
