I’ve noticed something about the kindest people I know. Almost none of them had it easy growing up.
That might sound counterintuitive. You’d think kindness would be a product of warmth, stability, and plenty of love during the formative years. And sometimes it is. But some of the most genuinely compassionate people I’ve encountered didn’t learn kindness because it was modelled for them. They learned it because they knew, with absolute clarity, what its absence felt like.
And that knowledge changed them. Not as a conscious choice, but as something closer to reflex.
Psychology has started catching up with what many of us have observed for years. The idea that suffering only produces damage is being challenged by a growing body of research showing that adversity can also produce something unexpected: deep, enduring empathy.
When suffering sharpens instead of hardens
The default narrative around childhood trauma is overwhelmingly negative. And for good reason. Adverse childhood experiences are linked to a long list of difficulties in adult life, from depression to relationship struggles. Nobody is arguing that a tough childhood is somehow a gift.
But the full picture is more complicated than the headlines suggest.
A study published in PLOS ONE by researchers at the City University of New York and the University of Cambridge examined whether childhood trauma was linked to heightened empathy in adulthood. Across multiple samples and measures, they found that adults who had experienced traumatic events during childhood showed elevated levels of empathy compared to those who had not. The more severe the trauma, the stronger the correlation with empathic concern for others.
The researchers suggested that empathy may be what they called an “end-product” of posttraumatic growth, something that develops as a person processes and integrates difficult early experiences over time.
I grew up working-class outside Manchester. It wasn’t a traumatic childhood by any serious measure, but it wasn’t soft either. My dad worked in a factory and got involved in the union. My mum worked in retail. What I absorbed from both of them wasn’t so much a lesson in kindness as a lesson in paying attention to people. My mum, in particular, had this way of noticing when someone was struggling before they’d said a word. She didn’t need a psychology degree to read a room. She’d lived enough to recognise discomfort when she saw it.
The science of compassion after adversity
The idea that suffering can produce kindness has a formal name in psychology: “altruism born of suffering.” The concept was introduced by researchers Ervin Staub and Johanna Vollhardt and published in the American Journal of Orthopsychiatry. They proposed that victimisation and hardship can lead to a strengthened sense of personal responsibility for others’ welfare, increased empathy, and a more positive orientation toward people.
This challenges the conventional wisdom that pain only breeds more pain. Staub and Vollhardt found evidence that people who had suffered, whether through family violence, natural disasters, or political persecution, often became more attuned to others’ distress rather than less.
Building on this, psychologists Daniel Lim and David DeSteno published findings in the journal Emotion showing that the severity of past adversity predicted increased trait empathy, which in turn was linked to a stable tendency to feel compassion for others in need. In a laboratory experiment, participants who had endured more hardship were more willing to step in and help a stranger who was struggling. The compassion wasn’t performed. It was automatic.
That word matters. Automatic. Because the people I’m describing, the ones who turned out kind despite everything, aren’t making a calculated decision to be generous. They’re responding from a place that was shaped long before they had any say in the shaping.
The difference between taught kindness and absorbed kindness
There’s a distinction worth drawing here, and I think the title of this piece captures it.
Some people are kind because they were taught to be. They grew up with attentive parents, good role models, and consistent reinforcement of empathic behaviour. That’s a real and valid path to compassion.
But there’s another kind of kindness. The kind that comes from having experienced its opposite so completely that withholding it from someone else feels impossible. Not because of a moral principle, but because the body remembers what it was like to need it and not receive it.
I’ve mentioned this before but I think one of the most important things therapy taught me, after my divorce, was the gap between knowing something intellectually and actually living it. I’d understood, in theory, that people need to feel heard. But it wasn’t until I went through a period of not feeling heard myself that the understanding became something I could truly act on. Smaller scale than childhood trauma, sure. But the mechanism felt familiar. You don’t just learn what absence means. You carry it.
Why this kind of kindness looks different
People who developed empathy through hardship tend to show it in particular ways. They’re often the first to notice when someone in a group is being left out. They’re attuned to what’s not being said. They tend to be better at sitting with someone’s pain without rushing to fix it or redirect the conversation.
This tracks with what the research shows. The Greenberg et al. study highlighted in Psychology Today found that childhood trauma was particularly linked to elevated affective empathy, which is the capacity to feel what others feel, rather than just understand it cognitively. These individuals don’t just recognise that someone is in pain. They feel the weight of it.
My sister is a nurse. She has this quality. She can walk into a room and immediately sense what’s going on beneath the surface. I used to think that was just her personality. But looking back, I think it was shaped by the same things that shaped all of us. Growing up in a house where money was tight, where you learned early to read the temperature of a room, where you knew when your dad had had a hard day before he’d taken off his coat. That kind of vigilance, when it’s processed well, turns into something valuable. It becomes a radar for other people’s pain.
Growth doesn’t erase the wound
It’s worth saying clearly: none of this romanticises a difficult childhood. The research on posttraumatic growth, as outlined in a review published in the Journal of Personality, is careful to note that growth and suffering can coexist. A person can develop extraordinary compassion and still carry the scars of what happened to them. The empathy that comes from adversity isn’t free. It often arrives alongside anxiety, hypervigilance, and a deep fear of letting people down.
I lost my dad a few years ago. In the time since, I’ve thought a lot about what kind of person I actually want to be, separate from what I do for work or what I think about the news. And one of the things I keep coming back to is that the people who mattered most during that period weren’t the ones with the best advice. They were the ones who’d been through something themselves and could simply be present without performing comfort.
That kind of presence doesn’t come from a self-help book. It comes from having once needed it desperately and knowing exactly what it’s worth.
The bottom line
Kindness that emerges from a tough childhood is a particular kind of kindness. It’s quieter. It’s more instinctive. And it’s often invisible to the people who haven’t experienced the same thing.
The research tells us what many of us have sensed for a long time: that adversity doesn’t only damage. In the right conditions, it can produce people who are more attuned to suffering, more willing to help, and more capable of the kind of empathy that actually makes a difference.
If you recognise yourself in this, know that the thing you carry isn’t just a burden. It’s also, quietly, a gift you give to everyone around you.
