What does it mean that capture context not just content?

Example: You read an article about decision fatigue and highlight: 'Judges granted parole at a 65% rate after meals and near 0% before.' Powerful stat. You drop it into your notes. Four months later you find it while writing something about team management. You stare at the highlight. Was it about judicial bias? Nutrition and cognition? Decision timing? Willpower depletion? You highlighted it because your team had just shipped a critical decision at 5pm on a Friday and you suspected fatigue drove the outcome — but the note says none of that. The content survived. The context — the reason you captured it, the connection you saw, the problem you were solving — evaporated the moment you closed the article. Now imagine the same capture with three extra lines: 'Source: Danziger et al. 2011 via Kahneman Thinking Fast and Slow ch. 3. Spark: Our Friday 5pm launch decision — were we the hungry judges? Connection: context belongs with the atom, also relates to batch processing timing.' Thirty seconds of context. The difference between a dead highlight and a living building block.

Try this: Pick five notes you captured in the last two weeks — quick highlights, bookmarks, meeting jottings, anything. For each one, add three context fields right now: (1) Source — where exactly this came from, (2) Spark — what problem or question made you capture it, (3) Forward link — one other note or project it connects to. Time yourself. If it takes more than two minutes per note, you are over-engineering. The goal is minimum viable context, not a research dossier. After all five are done, read each note as if you have never seen it before. Notice how the three context fields change your comprehension speed.
