Attachment theory

Attachment theory is a framework, first developed by psychiatrist John Bowlby and developmental psychologist Mary Ainsworth, about how people form and depend on close emotional bonds. It started as a theory of infants and their caregivers. In the 1980s researchers began applying it to adult romantic relationships.

The longer explanation

Bowlby argued that seeking closeness to a trusted person when you're scared or stressed is a built-in survival system, not a weakness. Ainsworth's "Strange Situation" studies watched how babies reacted when a caregiver left and came back, and grouped those reactions into patterns. Hazan and Shaver (1987) proposed that adult romantic love runs on a similar system: we look to partners for comfort, protest when they're unavailable, and settle when they come back.

Adult attachment research mostly measures two things: how much someone worries about rejection or abandonment (attachment anxiety) and how uncomfortable they are with closeness and depending on others (attachment avoidance). Most people sit somewhere on both scales. They aren't neatly one type or another.

Example

You notice that when your partner goes quiet you feel an urge to reach out more, while they seem to want more space. Attachment theory offers one way to describe that mismatch. It describes two nervous systems doing different things under stress. It doesn't name a villain.

What it is not

It isn't a personality test, a diagnosis, or a verdict on whether a relationship can work. It also doesn't say your attachment pattern is fixed for life.

Online use vs research use

Online, attachment theory is often reduced to four labels and a cast of characters (the anxious victim, the avoidant villain). Researchers describe continuous dimensions that can shift with relationships and life events. They also caution against "armchair diagnosing" a partner from short-form videos (Irish Times, 2023).
