The outline method is the one nearly everyone already uses without naming it: main points at the left margin, supporting details indented beneath them, sub-details indented further. It mirrors how structured information is organised, so it's fast to write and easy to scan later.
How it works
Topic
- Main point
- Supporting detail
- Supporting detail
- Main point
- Detail
Each indent level is a claim about relationship: this idea belongs under that one. That's the method's whole value — the hierarchy is the meaning.
Why it works
Because you decide structure as you go, an outline forces light real-time thinking: is this a new point or a detail of the last one? That question keeps you engaged instead of transcribing, which is the first principle of useful notes. And the finished outline is genuinely skimmable — the shape tells you where things are.
Where it shines
Anything already hierarchical and verbal: meetings, how-to talks, book chapters, planning sessions. It pairs especially well with our meeting-notes method — decisions and actions as top-level points, context indented under them.
Where it struggles
Outlines assume the material has a clean hierarchy. Fast, non-linear input (a brainstorm, a rambling discussion, connections that cross branches) breaks the indent model — a mind map or loose capture handles that better. Outlines also don't help you link ideas across notes; for that you want atomic notes and a Zettelkasten.
Doing it digitally
Outlining is where digital beats paper cleanly: bullets indent with a tap, collapse to hide detail, and rearrange by dragging. The risk is the opposite of paper's — endless nesting. If an outline grows five levels deep, that's usually a sign two or three points want to become their own atomic notes instead.
