It combines the four MBTI indices with the adult-attachment framework:
self-understanding content of this site's own making.
MBTI (the Myers-Briggs Type Indicator) is a personality-type instrument developed by the mother and daughter Katharine Briggs and Isabel Myers, built on the psychological typology of the Swiss psychiatrist Carl Jung.
It sorts human cognitive functions along four axes:
These four axes combine into the 16 types. The "Attachment MBTI" on this site and its free quiz are, however, original content: they are not affiliated with The Myers-Briggs Company or with any official MBTI certification body, and they do not provide an official MBTI assessment, certification or psychological test.
The British psychiatrist John Bowlby put it forward in the 1950s, and Mary Ainsworth's Strange Situation procedure gave it empirical support.
Research on adult attachment examines individual differences in anxiety and avoidance within close relationships. Childhood experience is one of the factors involved, but an attachment tendency is not a diagnosis fixed for life. It can change with the relationship, the setting, the period, and how you are when you answer.
Tends to hold basic trust in oneself and in others, and to balance closeness with independence fairly readily.
Tends to put a brake on closeness, to hold back expressions of feeling and requests for help, and to deal with things alone.
Tends to want strong assurance about the relationship, and to become sensitive to the other person's reactions and to shifts in distance.
Wanting closeness and wanting to avoid it sit side by side, and both anxiety and avoidance tend to run high.
The share of each type changes with the population, the scale and the way it is classified, so we do not present it as a universal proportion of the population. The shares on this site are published separately, as the anonymised aggregate of this site's respondents.
Two people can both be ENFP (the Campaigner) and still love in completely different ways, if their attachment styles differ.
Passionate and still able to trust the other person — freedom and bond in balance, the ideal version.
Big swings of feeling, love and anxiety arriving in turns. Gives too much, and burns out.
On its own, MBTI leaves the analysis at "you love freedom and you are creative". Combined with attachment theory, it can go as far as "why you turn out like this in love".
16 types × 4 styles = 64 types. That is Attachment MBTI, whole.
Here we call the loop in which the more anxious side's urge to check and the more avoidant side's urge to withdraw feed each other, for ease of understanding, "The attachment dance". It is a metaphor for a pattern in a relationship, not a law that holds for every anxious-avoidant couple.
Someone high in anxiety tends to seek reassurance about the relationship, and someone high in avoidance tends to withdraw when they feel pressed — so one person's approach can prompt the other's retreat, round and round. The lift that comes from an unpredictable response is sometimes mistaken for closeness itself.
The reasons people are drawn to each other, and where the relationship goes, differ from person to person. An attachment label on its own cannot settle what someone feels, whether they will cheat, whether you will get back together, or whether they are dangerous.
The avoidant one responds to the anxious one's ardent affection. Both feel they have met the one.
As it deepens, the avoidant one starts to feel hemmed in, and makes distance — replying less, filling the calendar.
The anxious one picks the change up at once and starts checking — flooding them with messages, demanding answers.
The avoidant one flees further, the anxious one chases harder. It can settle into an on-off relationship of breakups and reunions.
Consistently responsive, safe experience in a relationship can be one of the things that grows a steadier pattern with other people. That does not mean going out with a particular type will necessarily change anything: your own intention, the quality of the relationship, your circumstances, and professional support where it is needed all play a part.
Fearful-avoidant is how this site names, within its four categories, a state in which both anxiety and avoidance run high. Approach and retreat can happen at once, but the background cannot be put down to childhood trauma across the board. It is not a diagnosis either, and no cause can be identified without hearing it from the person themselves.
This quiz is a self-check of this site's own making. It is not a substitute for a validated clinical scale or for the official MBTI assessment; use the result as a way of ordering how you see yourself at the moment you answered.
Attachment MBTI is a site run by one person, with the aim of putting attachment theory and personality psychology into a form anyone can use. Every article is built on the academic literature — Bowlby and Ainsworth on attachment, the adult-attachment research that follows Hazan & Shaver, Mikulincer & Shaver's Attachment in Adulthood — with this site's own analysis of its quiz data laid over it.
Writing, data aggregation and the running of the site are done under the name Attachment MBTI editorial team, and the operator and editor in charge is Ryoya Oogane. For sources, peer-reviewed papers, academic books, public bodies and primary information come first, and what research has found is kept separate from this site's own interpretation and expectations. Where generative AI is used as an aid, the check on structure, the check on facts, the adjustment of wording before publication, and responsibility for publishing all remain with the operator and editor in charge.
Where an error, an update, or a concern about rights or privacy is confirmed, we consider correcting the passage, annotating it, or taking it down. Substantiated corrections about what an article says are welcome through the contact page. The editorial policy was last updated on 31 August 2026.
The statistical content on this site — the rarity rankings, the MBTI distribution by attachment type and so on — aggregates quiz answers as anonymised statistics. They are not stored or used linked to anything that could identify an individual. You are welcome to quote or reproduce the data and the charts, provided you credit "Attachment MBTI (mbti-svaf.com)" as the source and link to it.
This quiz and these articles are entertainment and educational content that supports psychological self-understanding; they are not a substitute for medical diagnosis or treatment. If distress — attachment difficulties, depression, anxiety — continues, please turn to a support service such as Japan's Ministry of Health, Labour and Welfare, "Mamorou yo Kokoro", or to a medical service or a professional such as a clinical psychologist.
