Secure attachment can be learned: what the research says about earned security in adulthood

“If all of this came from childhood, then that’s that, isn’t it? I can’t swap my childhood.”

A man in his forties said this to me after telling me a great deal about his family and very little about himself. His conclusion is logical and I understand why he reached it. But it is wrong — not because it would be nicer if it were, but because this is one of the few areas in psychology where we have twenty years of data on the same people, and where things turned out to move.

The term for that movement is earned security. It interests me mainly because it is used far too cheerfully. In this piece I will say what it means precisely, what the research actually shows, where the concept is seriously criticised, and what shifts quickly in practice as against what stays slow. I have written separately about how patterns repeat.

What earned security actually means

The term comes from how attachment is assessed in adults. Not with a questionnaire, but with an hour-long interview transcribed verbatim and then rated. The key point sounds strange: the rater is not interested in how lovely or how grim the childhood was. They are interested in how the person talks about it.

Whether the account holds together. Whether general statements match specific memories. Whether the person stays with the topic or gets carried off. Whether they can say something was hard without being squeezed mid-sentence into defence or into blame.

The earned-secure are those who describe a difficult early experience while their account is nonetheless connected and considered. So: not people without wounds. People whose wounds are no longer scattered around the room.

To my mind this is the most useful definition of security I know. It promises no peaceful life. It promises access to one’s own story.

What changes and what does not

People often expect therapy to change what they feel when they remember. That happens more rarely than we think, and it is not the main criterion. What changes is something else.

What changes is whether a person can reach their own experience at all without being flooded by it or having to deny it. What changes is whether they can hold two things at once: that their mother was in distress and that they missed her. Before, those two truths excluded each other and one had to be chosen. The capacity for both to stand together is, in fact, the whole thing.

And what changes is what a person does when something grips them. Not that it stops gripping them. But that afterwards it does not take three days before they come back into contact.

What the long-term studies show

There is not much data following the same people across decades, because it is expensive and slow. What exists says two things.

First: there is some stability. In a well-known study that assessed the same people as infants and again at around twenty, roughly seven in ten stayed in the same broad group, secure or insecure. That is not nothing.

Second, and more important here: the remaining third moved, and the movement was not random. It was linked to serious life events — the loss of a parent, severe illness in the family, divorce, events that were not small. Other studies have found lower stability than this. Meta-analyses pooling the data show stability that is moderate: large enough that the pattern is not chance, small enough that it is not fate.

From which follows something I like to say plainly: attachment does move, and it moves above all when life changes strongly enough that the old rules stop working. Therapy is one way of making that happen deliberately, and not the only one.

Where the concept is fairly criticised

Now the section that argues against my own thesis, and I think it is the most honest part of the piece.

Earned security was for a long time established retrospectively: a person described a hard childhood in the interview and had a coherent account, so we inferred that security had been earned. When a research group tested this in a sample where they also had prospective data on the actual care received in childhood, it turned out that adults classified as earned-secure had not received worse care in childhood than other secure adults. So part of what we took as evidence of change may be nothing more than a difference in how people narrate the past.

The same group found something else: the earned-secure reported more depressive symptoms than those secure throughout. Which makes sense. Someone who has genuinely walked the road knows a weight that others do not.

What does this mean for a reader? That the road is real, and the measurement is poorer than we would like. And that the distinction is worth keeping: we have evidence that an account can change. Evidence that this rewrites a childhood we do not have, and will not get.

What helps in practice

If I take from the research only what survives translation into daily life, four things remain.

A relationship in which contact returns after an argument. This is the strongest ingredient and also the least conspicuous. It is not a relationship without conflict, but one in which someone comes back after conflict. If a person has one such bond — with a partner, a friend, a therapist — it shows in the data.

Work on the account. In practice this means telling the same story repeatedly and each time slightly differently, until it connects. It is established that in therapies which do this systematically, narrative coherence and the capacity to think about inner states increase measurably.

Someone who was different back then. Many people had at least one adult in childhood who was predictable — a neighbour, a coach, an aunt. That experience often sits to one side and is not counted into the story, because “that wasn’t family”. In the work it is worth bringing back to the centre.

And self-compassion, which here is less soft than it sounds. In people with an insecure pattern the inner voice is as a rule sharp, and a changed account does not hold without softening that voice. I have written about this in the posts on self-compassion and the inner critic.

Why this can change at all

The question I am asked almost every time childhood comes up is whether it is too late. If something was imprinted in the first years, isn’t it set in concrete?

The short answer is that a pattern is imprinted not as a picture but as a prediction. Every time you find yourself in a situation resembling an old one, your nervous system forecasts what will happen and prepares the body for that forecast. A forecast is not a memory. It is a conclusion, and it updates when experience contradicts it often enough.

Which is also why explaining to someone that they are mistaken is not enough. The belief “if I show how I feel, this person will leave” does not shift by argument, because it did not arise from an argument. It shifts when a person shows it and nobody leaves — and when that happens often enough for the forecast to be rewritten. This is exactly why every route to earned security runs through a relationship, and exactly why they are slow. I have written about what neuroscience says about changing well-worn paths, and where those explanations reach their limits, in the post on neuroplasticity and therapy.

I would add one practical consequence. Because the forecast updates through experience, small frequent events matter more than grand revelations. Ten brief moments of saying you are struggling and getting a calm response do more than one shattering conversation at two in the morning. Therapy that happens once a week at the same hour is built that way for a reason.

What is fast and what is slow

Honestly: understanding is fast. Within a few weeks a person sees their pattern and can name it. That is the pleasant part, and people often think at that point that the job is done.

Everything else is slow. The first response in the body does not change with insight. A year or two after knowing exactly what is happening to them, a person’s alarm will still fire at a partner’s silence. What changes sooner is the time to repair and what they do while in that state. The alarm stays, the behaviour shifts. In time the alarm often quietens too, but that comes last, not first.

I am also careful with the word “processed”. People sometimes come wanting to close childhood once and for all. The more realistic aim is that the old story speaks up less often and does not take the wheel when it does. I have written about how movement is recognised at all in the post on signs that therapy is working. And if you are thinking of starting, the post on preparing for a first session may be useful.

Where the promise would be overstated

Some things I have to say even if they weaken the effect of this piece.

Security cannot be reached alone. At least in the data there is no route that is purely internal. Every route described runs through another person, and for people with an avoidant pattern that is the hardest part of the message.

Security is also not even. The same person can be secure in a friendship and insecure in a love relationship, because the old system only fires where most is at stake. Progress in one relationship does not transfer automatically to another.

And earned security is no protection from pain. Someone who has earned it suffers the same at a loss. The difference is whether they stay in contact with people while they do. That is a small difference on paper and an enormous one in a life.

Finally: if someone feels they have been trying for years and nothing is moving, there is a serious possibility that the problem is not an attachment pattern. Unrecognised depression, burnout, chronic pain or circumstances that cannot be changed often hide behind an explanation via childhood. Then the answer lies elsewhere.

What to remember

Earned security does not mean you have repaired the past, but that you have gained access to it. It is measured by whether the account of hard things holds together, not by how lovely things were. Long-term data show moderate stability and shifts tied to real events — so, not fate. The concept itself has a serious methodological weakness and that is worth knowing. The routes to it all run through relationship: through a bond that survives an argument, through therapy, through someone who was once different. And the most honest measure of progress is not that nothing grips you any more, but how long it takes you to come back.
