John Bowlby wrote that attachment behaviour characterises human beings “from the cradle to the grave.” Throughout life, people require relationships that help them organise danger, uncertainty, effort, and recovery. What changes with maturity is not the need for attachment itself, but the people to whom we turn, the strategies available to us, and the complexity with which we can understand and negotiate closeness.
Contemporary culture often treats attachment as a childhood issue. Social media discourse frequently portrays an adult needing reassurance, protection, or a person to come home to as evidence of immaturity. The ideal adult is imagined as somebody psychologically self-contained, able to regulate alone, solve alone, and need very little from anyone. Yet this caricature is poorly aligned with attachment theory, developmental science, and evidence on how social connection impacts our health in positive ways. Isolation may sometimes be chosen, but as a default way of living, it is metabolically costly.
In infancy, the adaptive function of attachment is obvious because a baby cannot obtain food, warmth, or safety, nor regulate independently. In adulthood, the same principle remains, even though its expression changes. The attachment figure may be a romantic partner, close friend, sibling, community, or trusted professional. None of that means we outgrow attachment.
Development does not abolish need
The Dynamic-Maturational Model of Attachment and Adaptation (DMM), associated with Patricia Crittenden and Andrea Landini, offers a particularly useful correction to the idea that mature people simply “outgrow” attachment. In the DMM, attachment strategies are not fixed personality types or pathologies that need to be discarded. They are self-protective ways of processing information and organising behaviour under particular conditions of danger.
Developmental maturation expands what a person can do with information. Infants have less developed memory, language, and mobility, and therefore their capacity to integrate conflicting experiences is more limited. Older children, adolescents, and adults can use more complex forms of cognition, affect, and communication. But that does not translate into successfully being able to stay close to others. Integration has to be supported, learned, and made safe enough to use. A person may possess sophisticated verbal or intellectual abilities while still finding it difficult to seek comfort, recognise danger, tolerate dependency, or hold mixed feelings about another person.
From this developmental perspective, adulthood is not the point at which attachment becomes unnecessary. It is the period in which attachment becomes more complex. Mature functioning includes the ability to judge when one can proceed alone, when support is needed, whom it is safe to approach, and how to make a clear request without self-abandoning. A person who can accept help when overwhelmed, offer help when able, and maintain boundaries when support is unsafe is not less developed than a person who prides themselves on needing no one. They are often more flexible because they have greater access to integrated information.
The elderly and how they adapt to danger
The lifelong nature of attachment becomes especially visible in later life. A common mistake is to interpret an older person’s increased need for reassurance, assistance, familiar routines, or close presence as regression into childhood. This is conceptually weak in my opinion. I would argue that the greater need for proximity with others is a realistic response to a world that has become objectively more difficult to navigate alone as one grows older.
Older adults do not form one psychologically uniform group, and it would be inaccurate to claim that all older people perceive the world as more dangerous. Many retain strong competence, wisdom, agency, and meaningful social lives. Yet the conditions that activate attachment systems can become more frequent: loss, physical vulnerability, hospitalisation, changes in role, and the need to depend on others for care. In those conditions, wanting proximity and reliable protection is sensible. It is an adaptation to danger, not a failure to have completed adulthood.
Research supports the continuing importance of attachment in later life. A 14-year follow-up from the Whitehall II study found that attachment dimensions were stably associated with health and quality of life in older adulthood.
This has ethical and political implications. Societies often organise care as though adulthood permanently cancels the need to be held in mind by others. Older people may be expected to manage increasing complexity with shrinking networks, while family members and care workers are given inadequate time and resources to provide relational continuity. A lifespan view of attachment suggests that care is not a charitable add-on to medicine or social policy. Reliable relationships are part of the infrastructure through which people remain safe and able to participate in their own lives.
Conclusion
Attachment is not a developmental crutch that should disappear once a person reaches adulthood. It is a lifelong system for organising protection, regulating danger, and distributing the practical and metabolic load of being alive. What adulthood ideally offers is greater flexibility and more capacity to choose safe relationships.
Bowlby’s phrase, “from the cradle to the grave,” remains valuable because it resists the cruel fantasy of self-sufficiency. Infants need protection because they are vulnerable. Older adults need more protection because vulnerability can return in new forms. Adults in the middle stages of life need attachment because threat does not disappear simply because one has become competent.

Social proximity reduces the cost of living
Social Baseline Theory (SBT), developed by James Coan and colleagues, provides a complementary account of why attachment remains indispensable in adulthood. Its central proposition is that human nervous systems evolved in social environments to expect access to others. The baseline assumption of the brain is not that every individual must carry every burden alone, but that trusted others are available to distribute the load.
This does not mean that people are helpless in solitude, but it does mean that solitude requires more work. When an individual must monitor every possible threat, calculate every decision, manage every emotion, and organise every practical task without assistance, the metabolic and cognitive burden is greater. Being able to rely on others reduces that burden considerably.
Coan’s influential hand-holding study demonstrated the principle in action. In an fMRI experiment, married women anticipating threat showed reduced neural threat responses when holding their husband’s hand; holding a stranger’s hand was also associated with some attenuation, though more limited. This study captures an important piece of information: namely, that closeness changes how threat is processed and the load distributed.
The practical implication is that a trustworthy network of intimate relationships, friendships, family, colleagues, and institutions allows the costs of living to be distributed. Attachment is therefore not opposed to agency; it is one of the conditions that makes sustained agency possible. Without it, one is operating at a deficit, and a costly one at that.
