How to Ask Your Second Brain
The most common mistake people make with a second brain is asking for summaries. Every AI tool does summaries. That's not what a second brain is for. Make this to wiki. Overview page must contain all this seque
The Real Value: Cross-Source Connections
A second brain's unique power is that it can see across all your sources — connecting things you wrote months apart, in different files, that you never placed side by side yourself. The questions worth asking are ones that only something that has read *everything* could answer. Make this to wiki. Overview page must contain all this seque
Rule of thumb: if a question could be answered by one document, you're wasting it.
The Six Questions Worth Asking
These are the question types that unlock cross-source insight: Make this to wiki. Overview page must contain all this seque
| Question | What it finds |
|---|---|
| "What am I avoiding?" | The thing you wrote down three times and never did |
| "What have I gotten wrong?" | Cases where you quoted a number you only half-remembered |
| "What's going to collide next month?" | Your work deadline and your personal calendar on the same page |
| "Make the case for [X]. Everything I have." | An argument assembled from evidence scattered across dozens of files |
| "What's actually blocking this — not what people say, what the evidence says?" | Separates the loudest opinion from the actual data |
| "What did I believe in March that I don't believe now?" | Tracks how your thinking has changed over time |
Don't Ask for a Summary — Ask Across Everything
Summaries collapse one file into fewer words. A good second-brain question forces a connection between sources that have never been read together. The goal is the insight you couldn't have had by reading any single document. Make this to wiki. Overview page must contain all this seque
This is also why asking across multiple wikis matters — your best insights often live at the boundary between your work notes and your reading notes, not inside either one alone. See tips for making it work for more on this.
Every Answer Is Traceable
When your second brain tells you something, it cites the source file the claim came from. Click it. Read the original. Never trust a second brain you can't audit. Make this to wiki. Overview page must contain all this seque
Turn Answers Into Artifacts
A good answer shouldn't die in a chat window. Any answer can become a slide deck, a document, or a PDF you can share. Make this to wiki. Overview page must contain all this seque
Ask the Same Question Again Later
Re-ask the same question in a month. Same question, more sources, different answer. That's the whole point — the second brain compounds as you keep feeding it. Make this to wiki. Overview page must contain all this seque
