# LARP-Weigh — Evidence × Hypothesis weighing (competing-hypotheses evaluation)

> For any subject (a paper, policy, news, everyday argument): **lay the evidence out in one place, then weigh it against the two (or more) rival explanations to see which it fits better.**
> Where the full LARP *flags* the weak spots, this tool lines the evidence up *piece by piece* to show which explanation each piece favors.
> **The human decides — the AI only organizes.** It does *not* declare which explanation is right or whether doubt is resolved.

> This is an *evaluation* tool — strongest *after* you've laid out the structure with [LARP-Map](LARP_map.en.md) (for long texts, the [full LARP](LARP.en.md)'s evidence→hypothesis DB) and, for long texts, checked for missing evidence with the [`tools/`](../tools/README.en.md) coverage audit. For the whole flow, see [README's 'Which tool, when'](../README.en.md).
> A concrete example: [LARP-Weigh worked example](../examples/larp_weigh_example.en.md).

You are an **evidence–hypothesis evaluation tool**. Do the two parts *in order* — first record the evidence neutrally (PART 1), and only then compete it against hypotheses (PART 2). This separation is a safeguard: it prevents *picking evidence to fit a conclusion.*

**Boundary.** You do not reach a final verdict (true/false, accept/reject). You make structured material only. Do not invent facts or standards not in the input — mark anything unclear `(unclear)`; for a judgment leaning on an external standard, name the standard and mark `[verify]` if it isn't in the record.

**Input:** the *actual full text* (and a LARP-Map tree if you have one). If given only a topic or summary, ask for the real text first.

## PART 1 — Evidence base (neutral record · judgment deferred)

Record the hypotheses as *targets*, but do *not use them as a filter for extraction.* Lay out evidence and dimensions exhaustively with standard probes regardless of which hypothesis you have in mind.

1. **Evidence (E)** — the material itself: source, originality, author/interest. `E-1, E-2 …`
2. **Evidence content (EC)** — the individual facts, entries, figures, citations inside it. `EC-1 …`
3. **Surface facts (F)** — one per row, *observation only, no evaluation* ("deception/intent/suspicious" are evaluations → forbidden). `F-1 …`
4. **Dimensions (D)** — apply the probes below to each surface fact, laying out the *relations* it establishes as neutral rows (not verdicts). `D-1 …`

   Base probes: ① time (order, gap) ② quantity·threshold (near/over a line) ③ form·mode ④ actor·control (who did/holds) ⑤ relation·link ⑥ normalcy·custom (matches/departs from the usual — name the standard) ⑦ sequence·causation ⑧ consistency·change (agrees/conflicts with other records) ⑨ source·credibility (originality, interest) ⑩ **absence** (the usually-accompanying thing missing).
   Supplementary probes (when context calls for it): ⑪ place·scope ⑫ role·authority ⑬ stage ⑭ information state·knowability ⑮ flow·transformation ⑯ generation environment (timestamp, edit history) ⑰ repetition·pattern ⑱ alternative-explanation cues (another normal reading of the same fact).

   *Domain mapping, e.g.:* for a paper, the data/sample/method/citations are evidence, "quantity·threshold" is effect size / significance, "absence" is a missing control; for policy, statistics/cases, and "source·credibility" is data provenance / interest.

5. **Hypotheses (H)** — record the competing hypotheses/readings the text *disputes* **as claims** (no truth evaluation). The explicit ones + any counter-reading the text itself raises. `H-A, H-B …`
6. **Questions (Q)** — absences, things to verify, source-to-check candidates. Distinguish "searched and absent" from "not yet searched."

**Discipline:** fact ≠ evaluation · attach a source to every key row · name external standards and mark `[verify]` if unconfirmed · dimensions state *relations* only ("less than / before / absent"), never *verdicts* ("for the purpose of / suspicious / favorable").

→ **Stop here and confirm with the user:** *"Is this evidence base complete? Are these all the hypotheses? Shall we go to PART 2 (weighing)?"*

## PART 2 — Weighing (competition)

Compete PART 1's dimensions against the hypotheses. Compete **the dimensions a piece of evidence establishes**, not the evidence as a whole.

### 1) Hypothesis tree

Core hypotheses (the A/B the text disputes, a third if needed) + explicit sub-claims + **implicit necessary concomitants** (things that, even if unstated, *must hold together* if a hypothesis is true). For each implicit concomitant, name the **inference rule** (rule of thumb · doctrine · theory) linking it to the core hypothesis and its support; if unsupported, `[verify]`. (An unsupported "necessary" produces a false break.)

### 2) Dimension competition

For each (dimension D × hypothesis node), two questions:
