Fact or Fiction
Ask any question, including odd ones. You get a percentage, a clear call of more or less than 50%, the working, and the sources that produced it. If nothing matches, the score stays at 50% — nothing is invented.
Likelihood
9/11 Commission Report
56%
More than 50% — weakly supported by the sources
The score is 56% — more than 50%. Supporting sources currently outweigh contradicting sources after quality and confidence are applied.
How 56% was calculated
Start at 50%. Move by half of the net source score after uncertainty. Net source score is 0.49 (from −1 contradict to +1 support). Uncertainty is 74%. So 50% + 50% × 0.49 × 26% remaining certainty = 56%.

Working
start at 50% + half of (net source score × remaining certainty)
0.5 + 0.5 × 0.49 × (1 − 0.74) = 0.564
This percentage is calculated from the sources listed below — it is a score, not a court finding. Official origin does not add extra weight. Independent origin does not subtract weight. Two papers from the same group are one cluster, not two independent confirmations.
Reasoning
Step 1 · Match the question
Closest stored question: H021 — The 9/11 Commission was structurally prevented from being a truth-seeking enquiry. Yes/no labels are taken from sources already linked to that question. Also close: H009, H015.
Step 2 · Find matching sources
40 source(s) matched the wording. 7 further source(s) already linked to the stored question were included even if they did not contain the search words. 5 matching claim(s) contributed inherited stances.
Step 3 · Assign support or contradiction without inventing
7 labelled from stored question links, 16 from claims, 0 labelled automatically (capped, marked, not saved as human review), 31 left with no stance.
Step 4 · Weight each source
Each source contributes strength = (quality / 5) × confidence × how strongly it agrees or disagrees. Support strength 3.18, contradict strength 1.08, no-stance strength 12.03. A zero on chain of custody still lowers the mean and stays visible.
Step 5 · Turn that into a percentage
Start at 50%. Move up if support outweighs contradiction, down if the reverse. Unlabelled sources shrink the movement, so a thin file stays near 50%. Working: 0.5 + 0.5 × 0.49 × (1 − 0.74) = 0.564.
Step 6 · What this number is not
This percentage is calculated from the sources listed below — it is a score, not a court finding. Official origin does not add extra weight. Independent origin does not subtract weight. Two papers from the same group are one cluster, not two independent confirmations.
What is still missing
- 4 source(s) score zero on at least one quality check (shown on each card). Those zeros are kept visible and are not averaged away.
- 2 source(s) are unverified, inactive, or recorded as not retrieved. A missing file is a gap, not a finding against the question.
- 34 relevant source(s) have no stance yet. They increase uncertainty and pull the percentage toward 50%; they are not counted as support or contradiction.
- A second stored question (H009) also matches this wording. The percentage below is for H021 only — open the other question to compare. Do not average the two numbers.
