Offloading Your Working Memory: The "Capture First, Sort Later" Method
ADHD working memory overloads fast. The capture-first method keeps ideas alive without requiring filing decisions in the moment — here's how.
You are in the middle of a task when a completely different thought appears: "I need to call the dentist." You try to hold it in mind while finishing the current sentence. By the time you look up, it is gone. Not suppressed — actually gone, evaporated from working memory.
Or: you hold the dentist thought, but now you have lost the thread of the current task. You are mid-sentence and cannot remember where you were going. Trying to hold one thing lost you something else.
This is ADHD working memory in action — not broken, just different in capacity and behaviour. The fix is to stop trying to hold things in mind at all, and instead create a fast, reliable capture system that makes holding unnecessary.
TL;DR
- ADHD working memory has reduced capacity for holding multiple things simultaneously.
- "Capture first, sort later" treats every note as an inbox item — captured immediately, without categorisation decisions.
- The capture step is sacred: it must be faster than the thought can be lost.
- Sorting can happen later, in batches, when you have time and cognitive bandwidth.
How ADHD working memory differs
Working memory is the mental workspace where you hold and manipulate information actively. Research consistently shows that people with ADHD have reduced working memory capacity — not necessarily in all domains, but particularly in the phonological loop (verbal information) and the visuospatial sketchpad (visual/spatial information).
A meta-analysis published in Neuropsychology Review found working memory deficits in ADHD across multiple measurement approaches, with the most consistent deficits in tasks requiring holding and manipulating information simultaneously.
The practical result: when you are working on Task A and a Task B thought appears, holding both simultaneously depletes working memory faster than for most people. One or both things will be lost unless one is externalised immediately.
The capture-first principle
The capture-first principle: get it out of your head before your working memory loses it, and do not make any decisions about where it goes until later.
No category. No tag. No project assignment. Just: captured.
The sorting step — deciding what goes where, what needs action, what can be archived — happens in a separate session with separate cognitive resources. The capture step happens in under 10 seconds.
This separation is important because capture and sorting require different types of thinking. Capture requires speed and immediate execution. Sorting requires evaluation, categorisation, and decision-making. Trying to do both at once is the reason most capture habits fail — you open the note app, realise you need to decide where to file it, hesitate, and lose the thought during the hesitation.
Building a capture system that keeps up with ADHD
The single inbox rule: One place. Everything. No exceptions. This is not where you file things — it is where you throw things before you decide what to do with them. Its only job is to not lose things.
Candidates:
- Apple Notes "Quick Note" shortcut (iOS) — opens a note immediately from lock screen
- Android Quick Notes widget — one tap, immediate capture
- Siri / Google Assistant — "Hey Siri, note [thing]" while doing something else
- A physical notebook on your desk for analogue capture
Voice capture: For thoughts that arrive while your hands are busy (driving, cooking, walking), voice is often faster and more reliable than text. The key is a frictionless trigger — a single-button shortcut that starts recording without unlocking your phone.
iOS Shortcuts can create this. Android has built-in voice memo shortcuts. Otter.ai (otter.ai) transcribes voice automatically so the note is searchable.
Physical capture: A small notebook (Field Notes size works well) in your pocket or bag provides a capture option that works without battery, signal, or unlocking. Many ADHD adults find physical capture less distracting than phone capture because it does not open a device full of other potential stimuli.
Let your capture system catch everything so your brain can focus on the current thing. Herding Chickens captures tasks and context automatically — no manual inbox required. Join the early access list.
The sorting session
Sort your inbox once a day or once every two days — not continuously.
The 10-minute sorting session:
- Open inbox
- For each item: read it and ask "does this need an action?"
- If yes: move to active tasks list
- If no: archive it (notes stay searchable; filing is not necessary)
- If unclear: archive it anyway — unsearchable unclear items are not useful whether filed or not
The session has a time limit. 10 minutes. If the inbox is larger than 10 minutes of sorting, that is fine — sort the newest items first (most likely to be still relevant) and leave the rest for tomorrow.
What not to capture
Not everything is worth capturing. The system works because it is fast and low-friction — loading it with everything that passes through your mind would make the sorting session unmanageable.
Good candidates for capture:
- Tasks you need to do (not now, but within the next week)
- Ideas you are excited about
- Reference information you will need later
- Commitments made to other people
Poor candidates:
- Thoughts you know you will remember naturally
- Interesting facts with no connection to anything you are working on
- Content you want to watch/read "someday" (use a separate read-later app like Pocket)
- Venting / emotional processing (use a separate journal or voice note)
