Attachment style

In plain words

An attachment style describes what you tend to do when someone gets close or pulls away: reach out, hold back, cling, or switch between the two. It is a description of a pattern in relationships. It is not a personality type and not a diagnosis.

Where the idea comes from

John Bowlby (1907–1990) developed attachment theory, set out in his trilogy Attachment and Loss (1969–1982). He proposed that infants need a consistent, responsive caregiver, use that person as a "secure base" for exploring, and form "internal working models" of relationships that colour later ones. Mary Ainsworth's Strange Situation procedure (1960s–1970s) sorted infants' reactions to separation and reunion into secure, anxious-avoidant and anxious-ambivalent patterns; Mary Main later added a disorganised pattern. Hazan and Shaver (1987) extended the framework to adult romantic relationships, and four adult styles are commonly described: secure, anxious-preoccupied, dismissive-avoidant and fearful-avoidant.

Attachment theory grew out of psychoanalysis but separated from it, and it sits close to object relations, which also asks how early relationships are carried inward.

How it shows up

A person who becomes anxious when a message goes unanswered, or who gets busy and distant when a relationship turns serious, is describing the kind of pattern attachment theory was built to explain. Oneli, the AI agent on TwentyThird, looks at how a member describes closeness and what they do after a warm moment, and returns that in plain words. It does not assign an attachment category, and it does not test anyone. Where a questionnaire or interview is wanted, a clinician or researcher uses a validated instrument. See attachment styles and repeating patterns.

What it is not

It is not fixed. A meta-analysis cited in the literature found no significant stability of attachment measured more than 15 years apart, and styles can change with later experience. The Strange Situation depends on stable family circumstances, and longitudinal studies that control for social background find weak links between infant attachment and adult outcomes. Critics also point to mother-blaming, to a neglect of genes, culture and wider families, and to evidence that several caregivers can raise secure children. A label from an online quiz is a prompt for thought, not a finding.
