Working memory holds roughly four items at once. That is not a personal limit you can train past — it is the size of the buffer. Everything above four is being held by effort, and effort is the thing ADHD does not have a steady supply of.
So the head fills. Not with thoughts you are thinking, but with thoughts you are holding in case you forget them. That holding is what makes the room feel loud at 11pm.
A brain dump empties the buffer. It works, and then most people do it once and never again, because the first dump produces a list of forty-seven items that is somehow worse than the feeling it replaced.
Why the first brain dump usually backfires
Because it stops being a dump halfway through. You write "call the dentist", and before the next item lands you are deciding when, checking whether the number is saved, and remembering the last appointment went badly. Three items later you are not emptying anything — you are running a planning meeting with yourself.
Capture and decide are two different jobs that use the same attention. Doing them at once means neither finishes. Barkley’s framing is useful here: ADHD is not a knowledge deficit, it is a performance deficit at the point of action. You know what needs doing. The breakdown happens when the doing and the deciding collide.
The four rules
1. Everything out, no sorting
One field. One list. No projects, no tags, no categories. If the tool asks you to choose a category before the thought is saved, the tool is charging you attention you came here to spend elsewhere.
2. No deciding while dumping
If a next step arrives on its own, write it as its own line and keep going. Do not chase it. The dump is the drain, not the plan. Deciding happens later, from a list, when the buffer is already empty and you have the room to think.
3. Flag what went stale
Items rot. Something written three weeks ago that you have walked past forty times is telling you something — either it is not actually yours, or it needs to be broken into a smaller first move. A stale marker makes that visible without asking you to review the whole list.
4. Close the box
This is the rule people skip and it is the one that makes the practice survivable. When the dump is done, close it. Not "review it once more" — close it. The point was to stop holding things. An open list you keep glancing at is still being held.
How often
Whenever the room gets loud. There is no correct cadence, and inventing one is how this becomes another thing to fail at. Some weeks that is daily, some weeks it is twice. A system that only works at a fixed frequency is a system that ends on the first week you miss.
The dump is the drain, not the plan. If it produces decisions, it produced them too early.
The setup
Mechanically, you need three things: a single input that opens in under two taps, somewhere the entries persist without being organised, and a stale signal that surfaces without you going looking.
- One capture field, reachable from the phone home screen
- No required properties — a thought saves with nothing but its text
- A date stamp, used only to compute staleness
- A way to close it that actually closes it
You can build that in a plain note. The reason to build it in Notion is the fourth point plus everything that comes after: at some stage you want the dump to feed a day that is planned by energy rather than by hour, and a note cannot do that.
