Persistent Demand for Autonomy

I had an epiphany right before the holidays about PDA, which (depending on the opinion of the person you’re talking to) stands either for “Pathological Demand Avoidance” or “Persistent Demand for Autonomy”. 

By now, you probably know which side of that equation I stand :) 

The topic came up while discussing the situation of an ND friend-of-a-friend who’d had some life arrangements made for her without her consent or input. These were trivial-but-obnoxious, the sort of interference an overbearing-but-well-meaning relative might do, and she’d been troubled by them to the extent that our mutual friend was questioning the wholesomeness of the situation. 

Our mutual friend is NT, and her concern was about respect and boundaries. But there’s another aspect to this, an important one, which I would like to explore in this article.

When you have a limitation that prevents you from accomplishing things the usual way, you develop workarounds. And those workarounds affect every decision that touches your limitations. 

Most of these workarounds are not even conscious, because they manage common activities, and must be subconsciously processed, because subconscious processing is very fast and easy. As I explain in this article you need the speed and economy of subconscious thought for most of what you do, or the doing would take so long you wouldn’t be able to do it. This is true for both neurodiverse and neurotypical people. 

But neurotypical people are more likely to do everything in the usual way, and (if they can’t) have an easier time identifying and negotiating for exceptions. Partly because they have fewer workarounds (and therefore more practice with each one) and partly because the accommodation is more likely to be familiar to whoever they have to explain it to. After all, everyone has limitations, and most of us have familiar ones.  

Neurodiverse people are much less likely to do things in the usual way. And - since “the usual way” is usual because it’s the easiest - their process is generally more difficult, and complicated. Which means more workarounds. And workarounds for those workarounds.

This can rapidly snowball into intricate, complicated coping systems with multiple interdependencies. All of which (remember) is being processed subconsciously at lightning speed. 

Systems with multiple interdependencies are fragile: even a small interruption can “cascade” into disastrous consequence. Complicated interdependent coping systems aren't necessarily a pathology, but they’re complicated. They are a lot of work. They’re also difficult to keep track of, because they’re mostly subconscious. 

Often, the only clue an ND person has about a potential disaster is a vague sense of unease: the problems created by the additional work only become apparent as the situation unfolds. This can be difficult (or awkward, or embarrassing) to explain. So they’re rarely known. 

And just as someone who’s never lived in a wheelchair normally won’t realize a step or a narrow passageway creates an impassible barrier for someone in a wheelchair, neurotypical people normally won’t realize that what to (to them) is an easy and reasonable course of action might seriously disrupt the ND’s delicate system of interdependent coping mechanisms. Therefore any decision not made by the ND person that affects them is a potential crisis. 

Everyone has limitations. Sometimes you know what they are, and sometimes you don’t. Even in ordinary (neurotypical) situations, decisions without consulting the person affected can inconvenience them, which is why it’s considered polite to first ask. But for anyone with a serious handicap, a decision made without taking their limitations into account can have very serious consequences. 

For example: I once visited a friend who didn’t understand my physical condition, and a few (seemingly minor) moves like this on her part ruined my trip, my health, and our relationship. We’d made plans together that were well within my capacities and therefore safe. Had the day unfolded as expected everything would have been fine.

But the last time I’d visited her was before my injury, and while she knew I had “lingering issues”, she didn’t realize the scope of my problems. So she made many changes to the plan as the day unfolded that were unexpected. And since these decisions were unplanned and unpredictable, they didn’t include the necessary reflection and negotiations I required to remain within safe limits. 

I got seriously hurt. So much so that I had to cancel my trip, spend hundreds of dollars (disabilities are expensive), and devote two painful weeks to physical therapy before I regained the function I’d lost by attempting that visit. 

It also seriously damaged the relationship: I was furious at her for her callousness, and her own limitations made it impossible to have the kind of frank discussion that builds reconciliation. We are still estranged.

I’ve used this example of physical disability and injury because it’s easy to understand. It should also be obvious that had I maintained absolute control of that situation - if I hadn’t needed my friend's cooperation to remain unhurt - nothing bad would have happened. If I had said NO to any deviation from our proposed course of action, everything (including my friendship) would have been fine. 

But polite behavior requires gracefully accommodating a host’s requests, unless the guest has a good reason not to. I hadn’t yet learned the necessity of saying NO to anything I hadn’t had the chance to fully think through and take precautions for. 

Furthermore, explaining yourself (over and over and over again) is tiresome. If your audience doesn’t already know, they probably won’t get it. Many people I know who are “different” - transexual, disabled, parent of a child lost to an accident (or worse) - have told me they were bothered by the burden of repeatedly explaining more than their actual difference. Add painful emotions to that difference (the grieving parent, for example) and that burden gets heavier.  

Persistent Demand for Autonomy is not about control for its own sake.

It is about risk management in a world that does not see your constraints.

PDA—however you interpret it—is neither pathological nor oppositional. It is not avoidance, and it is not defiance. It is the rational insistence on autonomy by someone who knows, often through painful experience, that decisions made on their behalf carry real and sometimes catastrophic risk. What looks from the outside like rigidity, overreaction, or knee-jerk refusal is often the visible edge of an internal risk calculation happening too fast—and with too many variables—to be consciously articulated in the moment.

When a person's functioning depends on fragile, largely invisible systems of accommodation and workaround, consent is not a courtesy—it is a safety requirement. Respecting that autonomy is not indulgence. It is the minimum condition for trust, safety, and sustainable relationships. The person experiencing PDA understands their own limits better than anyone else ever could, because they are the only one living inside the full complexity of those constraints. That insistence on control is not a behavior to be corrected or softened. It is vital information about what they need to remain safe and functional in a world that does not see their constraints.
