Idea Compass
A four-direction questioning frame for developing one note in a Zettelkasten-style vault. For any idea, ask what lies in each direction: North = where it came from, South = what it leads to, West = what resembles or supports it, East = what competes with, opposes, or could supercharge it. From Vicky Zhao & Fei-Ling Chang’s “Compass of Zettelkasten” (Linking Your Thinking conference); walkthrough by Zsolt in the ExcaliBrain video (full transcript captured as
clippings/7rnsULzez-g-transcript.md).
The four directions
| Direction | Question | What you hunt for |
|---|---|---|
| North (up) | Where did this come from? | Origins; parent domains and bigger categories “an order of magnitude higher”; the beliefs it supports |
| South (down) | What does this lead to? | Ideas this one nurtures; child domains; instances and examples |
| West (left) | What is similar? | Other disciplines the same concept applies to; others who expressed a similar thought; references |
| East (right) | What competes? | Opposition; what’s missing from the idea; disadvantages — and transformation: what could supercharge it |
The East quadrant is the part worth internalizing: competition isn’t only opposition — it’s also “transformation and supercharging” — items that combine with the idea to make something stronger. Zsolt grounds it in Sönke Ahrens’s How to Take Smart Notes: “the construction of oppositions is the most effective approach for generating new ideas.”
Why it beats a plain link pile
Directions are typed relations. A vault of undifferentiated wikilinks says “related”; the compass says how — upstream/downstream/kin/rival. That’s the same move as the map-of-content convention’s curated indexes and the understand toolfamily’s typed knowledge graphs: structure is what makes the vault queryable by both human and agent. Zsolt’s demo (ExcaliBrain pane in Obsidian) is literally the compass rendered as a graph view: parent categories north, examples south, similar ideas west, superchargers east — and the video’s best moment is the method working live: mid-explanation he realizes de Bono’s Six Thinking Hats belongs in the West of his compass note, and adds it.
Vault practice
- This garden already does North/South implicitly (hub notes’ sections move up/down abstraction); the compass makes it a checkable pass when a seed graduates
- East is the quadrant this vault underuses — most notes link kin (West) and origin (North) but rarely name what the idea loses to or what would supercharge it
- Kin: Concepts visualization (K-Plex/ExcaliBrain = the instruments), the map-of-content convention (MoC = curated index; compass = per-note relation discipline), Agent knowledge systems (typed relations are what make vaults agent-legible)
