Attachment styles — what the research actually shows

Attachment theory started with Bowlby’s observations of infants separated from caregivers, decades before it became a way for adults to describe their dating patterns.

From infants to adults

Ainsworth’s “Strange Situation” experiments sorted infant reactions to a caregiver’s return into patterns: secure, anxious, and avoidant. Hazan and Shaver later extended the same three-way framework to adult romantic relationships, arguing that early bonds shape expectations about closeness and reliability later in life.

Where online quizzes overreach

Attachment style predicts tendencies, not fixed traits. Studies tracking the same people over years find real movement between categories, especially after a relationship that behaves differently from what someone expected. A style is a starting pattern, not a diagnosis.

What holds up

• Style correlates, on average, with how someone responds to a partner’s absence or distance.
• A consistently responsive partner can shift someone’s behaviour toward more secure patterns over time.
• Self-report questionnaires measure how people describe themselves, not a direct read of infant attachment history — the correlation between the two is real but modest.
