Pathological Demand Avoidance and the Parts That Learned to Protect It
An Internal Family Systems reading of what demand avoidance is protecting.
Posted May 21, 2026 | Reviewed by Michelle Quirk
Pathological demand avoidance (PDA) is not an official diagnosis , yet it is gaining traction as a way of capturing a phenotype that isn't simply about finding demands difficult. It describes a relationship to the world in which a threat to autonomy is not merely annoying but registers as a primal, embodied threat to existence itself.
The term was coined in the 1980s by developmental psychologist Elizabeth Newson, describing children who reminded their referrers of autism but did not fit the picture as it was then drawn. She proposed PDA as a subgroup within what we now call the autism spectrum, and in the United Kingdom, it is most often described that way—though neither its place within autism (probably not autism-specific) nor its standing as a distinct construct is settled. Much of the most useful writing has come not from clinicians but from autistic writers—Sally Cat, Harry Thompson, Tomlin Wilding, Kristy Forbes—many of whom prefer "pervasive" or "persistent drive for autonomy," finding "pathological" tells the story from the outside, through the eyes of those being refused rather than the person doing the refusing.
Wiring Organized for Equity, Agency, and Freedom
However it is placed, PDA isn't—or shouldn't be—about behavioural problems. The moment we think that way, we are back in the world of compliance, and PDAers, like autistic people in general, have long been misrecognised as oppositional on the presumption that the problem must lie with us for not fitting in. Better understood, it is an autonomy-driven neurotype, one in which demands of every kind—internal expectations, social pressure, time, sequencing, even bodily needs—can land as threats. Crucially, this is not a wiring set against authority, but one organised for equity, agency, and freedom. As Tomlin Wilding puts it, the same drive that makes PDAers struggle to live under other people's rules also makes us natural activists and revolutionaries.
But affirming the wiring does not dissolve the suffering that often comes with it, and this is where I have been finding Internal Family Systems (IFS) useful. IFS views the mind as naturally multiple rather than unitary: not one fixed self but a system of parts, each with its own concerns and ways of trying to protect us, gathered around an undamaged core it calls the Self. From this perspective, PDA is not a problem to be sorted, nor something to be managed by borrowing the therapist's frontal lobe for advice or co-regulation—an arrangement that carries a power imbalance, and the imbalance itself tends to trigger the very inequity PDA cannot abide. Instead, the agent of healing is located within the person seeking help, a fact that in itself can soothe a PDA system.
Managers, Firefighters, and Exiles
IFS sorts parts into three broad kinds: managers, who work in advance to keep life controlled enough that pain never arrives; firefighters, who act in the moment once distress breaks through; and exiles, the younger wounded parts the other two are protecting. In a PDA system, the managers are often the most intelligent strategists in the room: the strategist, scanning ahead for hidden obligations and mapping the exits before entering a room; the negotiator, recalibrating language so that no one—not even one's own body—ends up positioned above or below; the charmer, deploying warmth and wit as social camouflage; the autonomy guard, alert to any incoming expectation, however small—or whatever managers a client finds and names for themselves.
It looks like this from the inside. An email arrives asking for something simple—a date, a yes, a form. Nothing about it is especially threatening, and part of the system genuinely wants to reply. But before anything is decided, the strategist is reading for the hidden ask behind the obvious one, and the autonomy guard has quietly closed the door. The reply does not get sent. Three weeks later, it still isn't, and now there is shame on top of the demand, which only makes the door heavier. This is what Sally Cat's writing on internalised PDA captures so well: the hyper-compliant child who becomes the adult agreeing to everything and then able to do none of it.
This is where a lot can go wrong in therapy . Therapists who do not understand PDA sometimes mistake these managers—the charmer, the autonomy guard—for the PDA itself. But to do that is to read PDA as psychogenic, something generated by the parts, rather than as a neurotype the parts have organised themselves around. A neuroaffirmative reading holds the order the other way: the neurotype comes first, and the parts grow up in response to it, and to a world that meets it badly.
Beneath the managers are the exiles, carrying the cost of having grown up where autonomy was misread as defiance: the misread child, told they were difficult or too much when they were in fact in autonomic distress; the lonely one, who learned early that no one quite saw what was happening inside; the shamed self, holding the belief that there is something wrong with how one is wired; the exhausted one, for whom masking has gone on so long that depletion has become baseline.
When the load on these exiles becomes unbearable, the firefighters arrive—fast, because the threat is felt as immediate. Sometimes that is shutdown—the body going quiet, so often misread as defiance when it is in fact collapse. Sometimes it is flight into fantasy , a creative refuge that lets the body rest from demand, or the more familiar reaches for substances, screens, food, or spending. And sometimes it is the rebel, the refuser—the sudden, shocking "no" to a person, a plan, a previously-wanted thing—protecting autonomy at the moment the system feels cornered.
The work of IFS is not to override any of this, but to help the Self come alongside the parts: to witness the managers and firefighters that have worked so hard, and to reach the exiles they have been guarding. As that happens, the internal environment grows less anxious . And in a less anxious system, a demand can sometimes be experienced as arriving from a more equal place—somewhere it can be genuinely weighed, chosen, or declined, rather than refused in that split-second moment when a demand threatens to tip the whole system over.
None of this rewires the terrain. The autonomy drive does not go anywhere; nor would we want it to. But when the parts no longer have to hold the line quite so fiercely, something begins to ease—and space opens up for play, for agency, for moving through the world on one's own terms. The thing once desperately wanted becomes, sometimes, possible again, and the world that had been quietly shrinking can begin, just as quietly, to widen back out.
