Main idea

The fixed workstation imposes a condition of access: you have to be at the screen, available, in a state where you are ready to organize your thinking. The condition looks innocuous because it describes the moment you work.

But many ideas don't arrive in that state. They arrive when the body is doing something else — walking, on public transport, coming out of a call, in the evening when the subject keeps turning. A tool that requires the working posture doesn't miss a few ideas at random: it systematically misses a whole class of ideas, those whose appearance is correlated with the absence of a desk.

Why it matters

The bias is invisible from inside the tool. It produces neither error nor alert: it simply produces a corpus that never contains what it could not receive. You then attribute the gap to yourself — "I didn't have any ideas" — rather than to the condition of access.

This is also what distinguishes mobility as comfort from mobility as coverage. Being able to work elsewhere is pleasant; being able to capture elsewhere changes what enters the system.

Nuances and limits

Permanent availability has its downside: a tool available at any moment also makes it possible to work at any moment, which is not the same thing as capturing at any moment.

And some tasks genuinely require the working posture. The criticism bears on capture, not on drafting.

Open questions

• Is there a way to check what a tool has missed, or is the absence unobservable by nature?
