One source at full depth per week beats ten at surface…

Process one information source at full depth (notes, connections, could-explain-to-others) per week rather than ten sources at surface level to build signal detection capacity in your critical domains.

When This Fires

  • During weekly reading/learning time allocation
  • When choosing between scanning many sources and studying one deeply
  • After noticing that large reading volumes aren't producing proportional insight
  • When building expertise in a core domain

Common Failure Mode

Processing at surface level and calling it "deep" because you spent 30 minutes on it. Full depth means: you took notes in your own words, you connected the ideas to 3+ existing notes in your system, and you could explain the key ideas to someone with zero context without looking at the source. If any of these criteria aren't met, you processed at medium depth — useful but not deep.

The Protocol

Weekly: (1) Choose one source from your Tier 1 or Tier 2 list (Tier your information sources) that warrants deep processing. (2) Read/watch/listen with active note-taking — in your own words, not quotes. (3) After consuming: write connections to existing knowledge. What does this relate to? What does it contradict? What does it extend? (4) Test: could you explain the key ideas to someone unfamiliar without looking at the source? If yes → fully processed. If no → continue processing until you can. (5) One source at this depth per week. Surface-scan remaining sources during a separate, shorter browsing session.
