The mechanism · Pervasive drive for autonomy
Why Can't I Do the Things I Actually Want to Do? PDA in Adults
You cleared Saturday morning for the one thing you have been looking forward to all week. You made the coffee. You sat down. And then you cleaned the oven instead.
Demand avoidance is a nervous system responding to a requirement as a threat to autonomy. It does not check who issued the requirement, so your own plans trigger it too. The moment something you wanted becomes something you must do, the wanting stops being enough to move you.
You cleared Saturday morning. The one thing you have been looking forward to all week, and you finally have three uninterrupted hours for it.
You made the coffee. You sat down.
And then you cleaned the oven.
Not because the oven needed doing. Because at some point between wanting it on Wednesday and having it on Saturday, the thing you were looking forward to turned into a thing you were supposed to be doing, and something in you put the shutters down.
What Is Actually Happening
There is a demand-avoidant response, and the thing worth understanding about it is that it does not check who issued the demand.
It reads a shape rather than a chain of command. Something has become required, and required is the trigger, and required is exactly what happens to a plan the moment you commit to it. You wrote it down. You told someone. You promised yourself two o’clock. Each of those is an ordinary, sensible act of organising your life, and each of them quietly converts a want into an obligation.
So the enjoyment does not protect you. It is closer to the opposite, because the things you want most are the ones you plan hardest, and planning is what builds the demand.
You are left standing in a kitchen at ten past nine on a Saturday, scrubbing an oven you do not care about, unable to explain why the good thing has become impossible.
Where It Comes From
The pattern has a name, and the name is having an argument with itself, which is worth knowing before you go looking it up.
It was described in the autism literature as pathological demand avoidance, PDA. A lot of autistic adults now use pervasive drive for autonomy instead, a reframe credited to the neurodivergent educator Emily Wilding and carried by organisations like Reframing Autism and AANE. Their objection is that the original names the behaviour and misses the need underneath it, and that calling a nervous system pathological for defending its own autonomy is both inaccurate and a rough thing to hand someone. There is no full agreement. Some people keep the original because it describes how total it feels.
I use the autonomy framing here, because it is the one that survives contact with what it actually feels like. You are not malfunctioning when this happens. A part of you is protecting your right to choose, and it is doing it clumsily, at enormous cost, against a threat that is not there.
Here is the gap I want to name. Almost everything written about this is written about children, and written for the adults managing them. Schools, parents, strategies, classrooms. Very little of it is written to a grown woman, and almost none of it deals with the specific problem of demands that are hers. That is the version that actually runs her week, and it is the one nobody covers.
What It Looks Like in a Dynamic
This is where it stops being an inconvenience and starts costing you something.
You will have noticed already that structure helps you enormously and structure ruins you, sometimes in the same week, and that nobody can explain why. It goes like this. Handing the demands to somebody else is genuine relief, because a requirement you did not issue does not sit on your autonomy the same way. That is real, and it is why so many people with this wiring end up wanting exactly this kind of relationship.
Then the structure beds in. The rules become yours by adoption. You have agreed to them, so now they are your commitments, and the same shutters come down on them that came down on Saturday morning. Week one it is a relief. Week three it is a wall. Nobody changed anything, and the whole thing quietly stops working.
Keep this separate from the command flinch, because they look the same and they are not. That one is about an instruction from him landing wrong because it arrived as a demand rather than a request, and the fix there is his delivery. This one fires with nobody in the room. Same shutters, no instruction, no one to adjust.
And keep it separate from the transition wall as well. That is the cost of stopping one thing and starting another, and it makes the first step expensive. This makes the first step forbidden, which is a different problem with a different answer.
What it usually costs you, if nobody names it, is a story about yourself. That you are lazy about the things that matter. That you sabotage your own good days. That you cannot be trusted to want something and then do it. None of that survives five minutes of understanding what is actually happening, but it takes up years first.
What To Do About It
The instinct is to add pressure. More discipline, a firmer deadline, a promise to someone else so you cannot back out. Every one of those raises the requirement, and the requirement is the problem, so every one of them makes it worse.
The move is to take the demand back out.
- Leave it started and unfinished. A book already open at the right page and a coffee already made is not a demand, it is a room you can wander back into. Set the thing up the night before and do not schedule it.
- Give yourself three real options rather than one plan. Autonomy survives a choice. Any one of three is doable in a way that the only one is not.
- Stop announcing it. Telling somebody you are going to do the thing is one of the fastest ways to convert it into an obligation you can no longer meet.
- Where somebody else holds the structure, let them hold it loosely and out loud. “That is on the list, we will see how you are on the day” keeps the shape and drops the requirement, and the difference between that and “you said you would” is the whole thing.
- When it fires anyway, name it in the moment and move on. Saying “the shutters are down on this one” out loud does more than an hour of trying to force it, and it stops you spending the afternoon building a case against your own character. That is the same self-prosecution that runs the held face, pointed inward instead of outward.
None of this is willpower. You have plenty of that, which you know, because you have been spending it on the oven.
Wanting something has never been what moves you. Being free to choose it is. Give yourself the choice back and the wanting works again.
Common questions
Why can't I do things I actually want to do?
Because wanting it and being required to do it are two different signals, and the second one can cancel the first. Once a plan becomes an obligation, even one you set yourself, a demand-avoidant nervous system treats it as a threat to autonomy and shuts the route down.
Can you have demand avoidance about your own plans?
Yes, and it is the part almost nobody explains. The response does not check where the demand came from. Writing it on a list, telling someone, or promising yourself you will do it at two o'clock can each be enough to turn a want into a requirement and stall it.
What does PDA stand for?
It was named pathological demand avoidance. Many autistic adults use pervasive or persistent drive for autonomy instead, a reframe credited to educator Emily Wilding, on the grounds that the original is stigmatising and describes the behaviour rather than the need underneath it.
Is demand avoidance the same as procrastination?
No. Procrastination puts off things you would rather not do. This fires hardest on things you genuinely want, which is why it is so confusing from the inside and so easy for other people to read as you not really wanting it.
How do I get moving when this happens?
Take the requirement out rather than adding pressure. Leave the task started and unfinished, give yourself several real options instead of one plan, or let someone else hold the structure so the demand is not yours to obey. Deadlines and discipline make it worse.
