Frame the claim
One narrow, testable proposition—not a mood, label, or bundle of allegations.
Use a relevant base rate or documented prior knowledge when possible. Avoid 0% and 100%: both make updating impossible.
Build a falsifiable hypothesis, audit the source chain, record evidence on both sides, and update confidence without pretending uncertainty has disappeared.

Ownership and incentives inform reliability; they do not settle whether a specific claim is true.
No source audit yet. Record the publisher, ownership, funding, relevant interests, and the original source behind the item.
Add evidence that supports, challenges, or fails to discriminate between H and not-H.
The ledger is empty. Search for evidence that could prove you wrong—not merely material that resembles your theory.
Separate established facts, inference, plausible risk, and unknowns.
The object is not perfect certainty. It is a working model whose confidence matches the available evidence.
Strip away the music, adjectives, montage, moral framing, and implied conclusion. Rewrite the material as small propositions that can each be checked.
Before investing in the page, leave it. Learn what independent sources say about the publisher, author, funder, owner, and cited evidence.
Ten articles may reduce to one press release, anonymous briefing, wire story, preprint, or clipped video. Count independent origins—not URLs.
A fact does not strongly support H when several ordinary explanations predict the same fact. Write the strongest alternative before scoring evidence.
Search deliberately for disconfirming evidence. Steelman the opposing explanation instead of attacking its weakest version.
The stopping rule is not “I feel vindicated.” It is “I can state the probability, the uncertainty, and what would change my mind.”
Evidence Ledger principle
Evidence can move confidence up, down, or barely at all. Strong claims need evidence that is much more expected if the claim is true than if it is false.
You may need only moderate confidence to investigate or add safeguards, but much higher confidence to accuse, publish, punish, or act irreversibly.
The workbench converts qualitative judgments into an auditable update. The number is a disciplined estimate—not a machine that manufactures truth.
Bayesian reasoning begins with a prior probability and updates it when new evidence arrives. The evidentiary question is comparative: how expected would this observation be if the hypothesis were true, and how expected would it be if the alternative were true?
A likelihood ratio above 1 supports H; below 1 challenges H; exactly 1 does not discriminate. The app asks for qualitative likelihoods, then discounts the update according to your rating of source reliability and independence.
Real-world evidence is rarely clean. Reports repeat one another, witnesses share information, and uncertainty in the evidence itself can be substantial. The app therefore applies a transparent heuristic: it shrinks the log-likelihood update when reliability is low or the item is derivative.
This adjustment is not canonical Bayes. It is a safeguard against false precision. If you have validated likelihood ratios from a technical field, use a proper statistical model instead.
It cannot repair fabricated inputs, determine whether your hypotheses are exhaustive, detect hidden dependence, or replace domain expertise. The ledger is most useful because it exposes your assumptions and makes revisions visible.
Report facts and inference separately. A good endpoint may read: “The mechanism is technically plausible and opportunity is established, but public evidence does not establish action or intent. Confidence remains moderate, and these findings would change it.”
