The science

Where the four types come from.

Not star signs, and not something we invented: five decades of published research, briefly told.

The short history

In the 1950s and 60s, the British psychiatrist John Bowlby proposed that humans are born with an attachment system: biological wiring that monitors whether the people we depend on are close, available, and responsive. Mary Ainsworth then showed, in her famous Strange Situation studies, that this system settles into observable patterns, and that the patterns differ from person to person.

In 1987, Cindy Hazan and Phillip Shaver published the paper that changed the field: romantic love, they showed, runs on the same attachment system, and adults show the same patterns with partners that infants show with caregivers. In 1991, Kim Bartholomew and Leonard Horowitz formalized the four-category model of adult attachment that virtually every serious test, book, and course uses today, including ours.

The four types, properly named

Our type names are ours; the categories underneath are the field’s. The mapping is exact:

The Anchor is what the literature calls secure attachment. The Pursuer is anxious-preoccupied. The Fortress is dismissive-avoidant. The Storm is fearful-avoidant, sometimes called disorganized. If you read the research, or take any well-grounded test, you will meet the same four patterns under their clinical names.

The two dimensions underneath

Modern attachment science measures pattern, not pigeonholes. Since the late 1990s, the field’s standard instruments (the ECR and its revision, the ECR-R) measure two continuous dimensions:

Attachment anxiety: how sensitively your alarm responds to distance, silence, and possible rejection. Attachment avoidance: how quickly closeness starts to feel like pressure. Every person sits somewhere on both axes, and the four types are the four regions of this map. Low on both is the Anchor. High anxiety alone is the Pursuer. High avoidance alone is the Fortress. High on both is the Storm.

This is why our report treats your type as a region, not a box: two Pursuers can sit in very different corners of the same quadrant, and the report is written from your position, not your label.

How our quiz measures it

The quiz has three parts. Twelve scenario questions put you in the moments where patterns actually show themselves (the unanswered text, the “I need space” conversation), because how you act under relational load is the pattern. Ten dimensional items, answered on the seven-point agree-disagree scale the research instruments use, place you on the anxiety and avoidance axes; these items are adapted from the constructs behind the ECR-R. And three context questions tell us where you are right now, so the paid report speaks to your actual situation rather than a hypothetical one.

Honest boundaries: this is a self-discovery product, not a clinical assessment, and no online questionnaire can diagnose anything. Attachment patterns are also not life sentences; the research on “earned security” shows patterns shift with new experiences, deliberate practice, and time. That is the premise the whole product is built on.
