Myth Buster: Attachment Style Is Not Permanent

Myth Buster — Attachment Style is Permanent

Your Attachment Style Is Not Set in Stone

Have you ever taken an online attachment style quiz and been told you're "anxiously attached" or "avoidantly attached"? If so, you may have come away believing that this label will define your relationships for the rest of your life. Fortunately, that isn't what attachment research shows.

Your Attachment Style Can Change

One of the biggest misconceptions about attachment theory is that people develop a single attachment style in childhood that never changes. While our earliest relationships certainly influence how we approach closeness, trust, and intimacy, decades of research have shown that attachment styles are not permanent personality traits. Instead, they are relatively stable patterns that can change as people gain new experiences, build healthy relationships, and develop greater emotional security. In fact, one of the most hopeful findings in modern psychology is that people can develop what researchers call earned secure attachment—a secure style that develops later in life, even after an insecure childhood.

What Is Attachment Theory?

Attachment theory was first developed by British psychiatrist John Bowlby during the 1950s. Bowlby proposed that infants are biologically wired to seek closeness with caregivers because doing so improves their chances of survival. When caregivers are consistently responsive and supportive, children tend to develop a sense that the world is safe and that other people can be trusted.

Psychologist Mary Ainsworth later expanded Bowlby's work through her famous "Strange Situation" experiments, identifying patterns of attachment that eventually became known as secure, anxious, avoidant, and disorganized attachment. These early relationships create what Bowlby called internal working models—mental expectations about ourselves, other people, and relationships.

Importantly, Bowlby never argued that these internal working models were unchangeable. He described them as working models because they are continuously updated as we gain new experiences throughout life.

Why People Think Attachment Never Changes

The myth that attachment styles are fixed comes from an important observation: attachment patterns often show continuity over time.

Children who develop secure attachments are somewhat more likely to become securely attached adults, and those with insecure attachment histories often carry some of those patterns into later relationships. Because of this stability, many people mistakenly assume that attachment styles are permanent. However, stability does not mean permanence.

Think of attachment like physical fitness. Someone who exercises regularly is likely to remain fit over time, but that does not mean their fitness can never improve or decline. Similarly, attachment styles are influenced by experience, and experiences continue throughout life.

Relationships Continue to Shape Us

Modern attachment researchers emphasize that our relationships never stop influencing us. Supportive romantic partners, close friendships, healthy family relationships, mentors, and even therapists can gradually reshape our expectations about trust and intimacy. Conversely, traumatic experiences such as abuse, betrayal, or repeated rejection can move even securely attached individuals toward greater insecurity.

A major review by Fraley and Roisman concluded that although attachment has roots in early caregiving, early experiences do not determine adult outcomes. Instead, attachment continues to evolve throughout childhood, adolescence, and adulthood as people encounter new relationships and life experiences.

The Science of Attachment Change

Researchers have now followed thousands of people across many years to examine whether attachment styles remain stable.

The evidence consistently shows both stability and change.

A recent comprehensive review concluded that attachment security changes throughout life in response to meaningful relationships, stressful life events, and developmental experiences. While many people remain relatively consistent over time, others become more secure or more insecure depending on what they experience. Rather than viewing attachment as fixed, researchers increasingly describe it as a dynamic process that balances continuity with adaptation.

This flexibility makes sense from an evolutionary perspective. If relationships help us survive, it would be adaptive for our expectations about relationships to update when the people around us change.

Earned Secure Attachment

Perhaps the most encouraging concept in attachment research is earned secure attachment. Earned security refers to adults who may have experienced inconsistent, neglectful, or difficult caregiving during childhood but later develop healthy, secure relationship patterns. They learn that not every relationship resembles those early experiences.

This change rarely happens overnight. Instead, it often develops gradually through repeated experiences of trust, reliability, emotional support, and healthy communication. Every positive interaction provides new evidence that challenges old assumptions about relationships. Rather than asking, "Will people always leave me?" a person may slowly begin thinking, "Some people really are dependable."

Therapy Can Help

One reason psychotherapy is often effective is that it provides a consistent, supportive relationship in which new attachment experiences can occur. A systematic review examining attachment during psychotherapy found that many clients showed increases in attachment security and decreases in attachment anxiety following treatment. Although researchers continue studying exactly how these changes occur, the overall evidence suggests that therapy can help people develop healthier relationship patterns over time.

Researchers have also explored security priming, an intervention that repeatedly activates feelings of safety and support. Early studies suggest that repeated experiences of psychological security may gradually strengthen more secure attachment patterns, although additional research is still underway.

Attachment Is More Flexible Than Social Media Suggests

Social media often portrays attachment styles as fixed identities:

"I'm anxious attached."

"He's avoidant."

"She's fearful avoidant."

Although these labels can help people recognize relationship patterns, they are descriptions, not diagnoses. They are not permanent categories, nor do they fully define a person's relationships. In fact, many researchers now recognize that attachment can vary across relationships. Someone may feel highly secure with one partner but anxious with another, depending on the quality of the relationship, the partner's behavior, and the surrounding circumstances. Our attachment system responds to the people around us—it is not simply a personality label we carry unchanged throughout life.

Growth Is Part of Human Development

The idea that attachment can change fits with a broader principle found throughout psychology: people continue developing across the lifespan. Just as personalities mature, coping skills improve, and emotional regulation strengthens with experience, attachment patterns can also evolve. Healthy relationships teach us new ways of thinking about ourselves and others. Every experience of reliability, empathy, and trust has the potential to update our internal working models.

This does not mean change is easy. Attachment patterns often develop over many years, so meaningful change usually requires time, repeated positive experiences, and sometimes professional support. But the evidence is clear that change is possible.

The Bottom Line

One of the most hopeful discoveries in modern attachment research is that your childhood does not permanently determine your future relationships. Early experiences matter, but they do not write the final chapter. Attachment styles are best understood as learned patterns, not life sentences. Healthy relationships, supportive friendships, psychotherapy, and intentional personal growth can all help people develop greater security over time. Rather than being trapped by the past, our brains continue updating their expectations as we encounter new evidence about ourselves and the people we love.

In other words, your attachment style is not who you are. It is simply the way your mind has learned to navigate relationships—and like many things we learn, it can also be relearned.
