Attachment is not a destiny
Four labels circulate everywhere, drawn from a theory that stopped using them long ago. What the research actually says is more interesting, and far less definitive.
Where these words come from
Attachment theory was born from the work of the British psychiatrist John Bowlby, who observed children separated from their parents after the Second World War. His thesis, set out from 1969 onwards, is that the need for proximity is a primary need, and not a by-product of the satisfaction of hunger as the theories of his time maintained.
The psychologist Mary Ainsworth gave him an instrument of measurement at the end of the 1960s, the strange situation, which observes a one-year-old's reaction to a parent leaving and then returning to an unfamiliar room. She drew three profiles from it, published in 1978; a fourth was added in the 1980s.
The leap to adults
It is an article by Cindy Hazan and Phillip Shaver, published in 1987, that transposes these categories to adult romantic relationships. The labels circulating today descend directly from it.
That leap is also the most disputed link in the chain. One moves from direct observation of behaviour, in young children, to questionnaires in which adults describe their own way of loving. It is not the same operation, and nothing guarantees it measures the same object.
Two axes, not four boxes
Research has largely abandoned the categories in favour of two continuous dimensions: anxiety about the other's availability, and discomfort with closeness. The reference instrument, published in 1998 by Kelly Brennan, Catherine Clark and Phillip Shaver, measures these two axes.
The four popular labels then correspond to zones of a plane, not to separate types. The difference is decisive: on a continuum, nobody is purely on one side, and two people filed in the same box can be very far from each other.
What moves
Follow-up studies show moderate stability, not mechanical continuity. Positions on these two axes shift with the relationships lived through, the break-ups and the lasting bonds, and the direction of causality is not settled: functioning influences relationships, and relationships modify it.
Saying of someone that they are avoidant, as one would say they are short-sighted, therefore lends a transitory state the solidity of a characteristic. The exact phrasing would be that they currently score high on one dimension.
Use and misuse
The most common misuse consists in assigning oneself a label like a blood type. Once taken on, it serves to explain in advance what one does, and therefore to stop examining it, which cancels out exactly the benefit the theory could bring.
Its real contribution is more modest and more useful: it supplies words to distinguish needs that everyday vocabulary confuses. Needing presence, needing reassurance and needing space are not the same thing, and a named need becomes discussable, which an unformulated unease never is.
Key points
The four popular labels come from a state of the theory that research has moved past: it now reasons in two continuous dimensions.
The move from the observed child to the adult describing themselves is the most disputed link in the chain.
Positions on these dimensions shift with the relationships lived through: a style is neither a diagnosis nor a destiny.
