Claim-routed reading may beat reading-first for synthesis notes

Type: kb/types/note.md

Status: conjecture. Motivated by one practitioner account (Learning By Writing); untested in this KB. Treat it as a hypothesis with a named test, not a finding.

The default multistage path reads the sources, then synthesizes: gather everything relevant, then find the claim. Karnofsky's inversion is to write a provisional bottom-line claim first — before being "qualified" — and let that claim decide what to read next: identify the subquestion most likely to change the claim, read narrowly toward it, revise, repeat. Reading is in service of writing, not the reverse.

The conjecture is that, for a note synthesizing several sources, claim-routed reading produces a better-warranted note at lower context cost than read-then-synthesize.

Mechanism: the claim is a selection pressure

A written claim names what would overturn it. That turns an open-ended "read the sources" into a targeted search: read the passage that could move the claim, skip the passages that could not. Warranted reader update is the objective, and a committed provisional claim supplies the selection pressure that an open gathering pass lacks — a bare writing prompt does not determine the contribution, but a provisional claim does, provisionally.

Two benefits are hypothesized. First, context economy: comprehensively reading every source spends bounded context on material that never bears on the claim, while routing reads only what could change it — relevant where context is the scarce resource. Second, warrant: a note built by surviving a sequence of claim-changing challenges retains the reasoning that selected it, rather than a pile of gathered facts whose relevance to the claim was never tested.

Failure mode: anchoring

The same claim that routes reading can bias it. If the provisional claim only ever selects confirming passages, the loop launders a first guess into a fake conclusion. Karnofsky's countermeasure is to route toward the disconfirming subquestion on purpose, and to periodically flip the hypothesis and argue the other side even when unconvinced. Without that, claim-routing is worse than reading-first, not better: it is passive assent dressed as inquiry. So the conjecture holds only for a routing loop that spends its selection budget on what could break the claim.

Scope

The claim is about multi-source synthesis notes — the ingest-and-multistage register where a note's value is the selected relation among sources. It does not apply to single-source capture, faithful transcription, or a note whose contribution is already determined before any reading.

How this could be wrong

The discriminating test is a comparison, not an intuition: build the same synthesis note both ways — claim-routed and read-then-synthesize — and compare the warranted update and the context cost. If routed reading yields the same note, it bought only a feeling of focus. If it yields an anchored note that never seriously read against its first claim, the failure mode dominates and reading-first is safer. The conjecture is that a disconfirmation-routed loop beats reading-first on warrant per unit of context; anything less refutes it.

Open questions

  • Can an agent reliably pick "the subquestion most likely to change the claim," or does that judgment need the comprehensive read the routing is trying to avoid?
  • Does routing belong as a replacement for the multistage workflow's reading stage, or only as a heuristic inside it?
