Why does atomic notes fail?

The most common reason atomic notes fails: Writing notes that look atomic because they're short, but actually contain two ideas joined by 'and' or 'also.' The note 'Atomic notes improve retrieval and enable better writing' contains two distinct claims — one about findability, one about composition. Each deserves its own container because they connect to different arguments and different evidence. Length is not atomicity. A 500-word note exploring one concept in depth is more atomic than a 20-word note smuggling in two.

The fix: Open your note system and find your five most recent notes. For each one, ask: does this note contain exactly one idea I could explain in a single sentence? If a note contains two or more distinct ideas, split it. Create one note per idea, give each a clear title that states the claim, and link them back to each other. You should end with more notes than you started with — and each one should be a standalone unit you could drop into any future argument.

The underlying principle is straightforward: A note that captures exactly one idea can be understood without its original context, linked to any argument, and recombined indefinitely — a note that captures two ideas can do none of these things reliably.
