# notes function as cognitive anchors that stabilize attention during complex reasoning by externalizing reference points that survive working memory degradation

Working memory holds roughly four items simultaneously (Cowan). A multi-part argument exceeds this almost immediately. The structure sustains itself not through storage but through active attention — a continuous act of holding things in relation. When attention shifts, the relations dissolve, leaving fragments that can be reconstructed but not seamlessly continued.

Notes function as cognitive anchors that externalize pieces of the mental model into fixed reference points persisting regardless of attention state. The critical distinction is between reconstruction and rebuilding. Reconstruction from anchors reloads a known structure. Rebuilding from degraded memory attempts to regenerate a structure that may have already changed in the regeneration — you get a structure back, but it may not be the same structure.

For LLM agents, this is architectural rather than metaphorical. The context window is a gradient — early tokens receive sharp, focused attention while later tokens compete with everything preceding them. The first approximately 40% of the context window functions as a "smart zone" where reasoning is sharpest. Notes loaded early in this zone become stable reference points that the attention mechanism returns to even as overall attention quality declines. Loading order is therefore an engineering decision: the first notes loaded create the strongest anchors.

Maps of Content exploit this by compressing an entire topic's state into a single high-priority anchor loaded at session start. Sophie Leroy's research found that context switching can take 23 minutes to recover from — 23 minutes of cognitive drag while fragments of the previous task compete for attention. A well-designed MOC compresses that recovery toward zero by presenting the arrangement immediately.

There is an irreducible floor to switching cost. Research on micro-interruptions found that disruptions as brief as 2.8 seconds can double error rates on the primary task. This suggests a minimum attention quantum — a fixed switching cost that no design optimization can eliminate. Anchoring reduces the variable cost of reconstruction within a topic, but the fixed cost of redirecting attention between anchored states has a floor. The design implication: reduce switching frequency rather than switching cost.

## Challenges

The "smart zone" at ~40% of context is Cornelius's observation from practice, not a finding from controlled experimentation across models. Different model architectures may exhibit different attention gradients. The 2.8-second micro-interruption finding and the 23-minute attention residue finding are cited without specific study names or DOIs — primary sources have not been independently verified through the intermediary. The claim that MOCs compress recovery "toward zero" may overstate the effect — some re-orientation cost likely persists even with well-designed navigation aids.

Relevant Notes:
- [[long context is not memory because memory requires incremental knowledge accumulation and stateful change not stateless input processing]] — context capacity is the substrate on which anchoring operates; anchoring is the mechanism for making that substrate cognitively effective
- [[cognitive anchors that stabilize attention too firmly prevent the productive instability that precedes genuine insight because anchoring suppresses the signal that would indicate the anchor needs updating]] — the shadow side of this mechanism: the same stabilization that enables complex reasoning can prevent necessary model revision
- [[knowledge between notes is generated by traversal not stored in any individual note because curated link paths produce emergent understanding that embedding similarity cannot replicate]] — wiki links strengthen anchoring by connecting reference points into a navigable structure; touching one anchor spreads activation to its neighborhood
