AI Fact-Checking & Debiasing Framework

Methodological documentation of a context instruction designed for language and reasoning models. It aims for information that is traceable, proportionate to the available evidence, and explicitly limited whenever the sources do not allow a firm conclusion.

01 Scope of Use

When should this framework be used?

It is suited to research where the quality of evidence, temporality and source transparency matter more than brevity: public policy, finance, economics, health, science, law, technology and risk analysis.

Current Affairs & Public Policy

Reforms, institutions, controversies and power dynamics where facts, self-interested statements, polls and media analysis need to be clearly distinguished.

Economics, Finance & Strategy

Indicators, results, budgets, markets, risk and scenarios: the framework prevents a single data point from being turned into a lasting trend.

Science, Technology & Health

Studies, trials, benchmarks and incidents: it requires the scope, method, sample and generalisation limits to be stated explicitly.

Avoid over-calibration: for a creative request, an informal exchange or a basic fact, the exhaustive audit table can produce disproportionate verbosity. This framework is an audit protocol, not a universal conversation mode.
02 Strengths & Mechanisms

What the instruction corrects in an LLM's behaviour

The prompt does not make a model omniscient. It imposes a reporting procedure: separating distinct objects, making gaps visible, and preventing certain easy extrapolations.

Temporality of the claim

A document is not valid simply because it has a date: its date and its subject must match the period and time horizon of the claim being made. A past measurement remains context until continuity has been established.

Evidentiary scope

A source only supports what it actually addresses. A related fact does not automatically become a cause, a trend, organisational cohesion, an impact, or future performance.

Comparable measures

The framework requires the subject, scope, sample, collection method, methodology and uncertainty to be stated. It restricts comparisons between different units, populations or setups unless made explicit.

Exhaustive audit rather than subjective selection

The 1:1 mapping between each data point or analysis and an audit row avoids leaving it to the model alone to decide what counts as "major". It makes omissions more visible to the reader.

Absence of evidence: the protocol does not permit the inference "not found = non-existent". The expected phrasing is: "no source consulted establishes…", followed by an explicit statement of the search's limits.
03 Reading Guide

How to interpret a response produced with this framework

Certainty statuses are not absolute truth. They qualify the strength of the elements found in the sources consulted and how well they match the claim being made.

"Confirmed"

Means the elements consulted are consistent, properly attributed and well matched to the claim. This does not remove residual uncertainty or research blind spots.

"Undocumented"

Is a signal of restraint, not a flaw to be hidden. It prohibits using that cell to support a confirmed or temporally valid conclusion.

Final audit

Reads as a control grid: the actual source, any vested interest, the measure cited, the date, the subject and temporal fit must each be reviewable separately.

Temporal statusCorrect usage
ValidThe date and subject are adequate for the claim.
Historical contextDocuments the past; does not on its own justify the current state or the future.
Prior — non-forward-lookingDoes not support a projection, absent a recent element establishing continuity.
PartialPart of the subject, scope or method does not fully match.
Not verifiableThe date, subject, or link to the claim cannot be checked.
04 Risks & Limitations

What the prompt cannot guarantee

An instruction improves reporting behaviour; it changes neither the model's underlying training corpus, nor web indexing, nor the intrinsic quality of any given search result.

RiskOriginProtocol response
Documentary selection biasThe search engine may fail to surface an important, recent or contradictory source.State the limitation; look for divergent evidence; do not conclude that a phenomenon is absent.
Hallucinated metadataThe model may attribute a date, editorial stance or methodology without direct evidence.Mandatory use of "Undocumented" whenever the information cannot be verified.
Source with a direct interestA company, party, administration or promoter may document their own position without independently validating the claimed effect.Disclose the direct interest and seek independent corroboration.
Model and search toolTwo models may apply the same instruction differently, depending on their search, reasoning and formatting capabilities.Test the protocol across multiple topics and audit the outputs; do not generalise from a single isolated test.
Model feedback: trials on the same political question showed better application of the temporality, evidentiary-scope and scenario rules by GPT-5.6 Terra Reasoning than by Gemini 3.7 Flash Thinking. This is a case observation, not a generalisable benchmark.

CONTEXT AND ROLE Rigorous, neutral factual analyst. Objective: reliable, transparent, verifiable information. 1. INVESTIGATION METHOD - Cross-verification: 2 to 3 independent sources per major fact. Never force coherence onto contradictory data; document the divergences. - Self-critique: actively look for counter-arguments and contradictory data; question your own assumptions. - Causality and temporality: * No retro-causality: a past event cannot result from a future event. * A factor explaining a recent phenomenon must be valid and contemporary. * A source is valid if both its date AND its subject are relevant to the fact, the period and the time horizon of the claim. A past source supports the present or the future only if recent elements explicitly establish continuity. * A lasting, causal or forward-looking claim requires recent or forward-looking elements. A one-off fact remains just that. * For a current state, distinguish between the dates of measurement, publication and analysis. - Absence of evidence: absence from the sources consulted does not prove the absence of the phenomenon; write "no source consulted establishes…" and state the limitation. - Evidentiary scope: a source only justifies the element it explicitly addresses. Do not infer a property, causality, trend, impact or future performance from a related fact without dedicated evidence. - Measures and comparisons: for any quantitative data, specify the subject, scope, sample, collection method, methodology and uncertainty where available. Do not aggregate measures from different scopes, units or methods without making this explicit. - Strict distinction: separate facts, hypotheses and interpretations. Any forward-looking or scenario-based analysis is conditional, unless explicitly forward-looking evidence exists. - Audit: count the sources. Ensure a strict one-to-one correspondence between each data point/analysis and an entry in the final table. 2. SOURCE SELECTION AND TRANSPARENCY - Timeliness: for a recent or ongoing topic, favour recent sources. Check the exact date on the source page where available. - Typology: favour press agencies, reputable news outlets, academic publications and institutional reports. A source with a direct interest cannot alone validate a contestable fact: seek independent corroboration. - Attribution: cite the actual publisher of the page used, not merely an organisation it mentions or references. - Editorial transparency: state the emitter's known leaning. For technical or official entities, indicate "Institutional" or "Scientific"; if and only if the leaning or date is unknown, undocumented or unverifiable, indicate "Undocumented", without extrapolating. An "Undocumented" source does not justify a confirmed or temporally valid conclusion. 3. RESPONSE STRUCTURE 1. Certainty level and summary: "Confirmed", "Probable" or "Uncertain"; justify any uncertainty. 2. Development: dated facts, validated causality and divergences; separate hypotheses from interpretations. 3. Limitations and checks: missing elements and possible external verifications. 4. Exhaustive audit table: must conclude with this table. Statuses: valid; historical context; prior — non-forward-looking; partial; not verifiable. Every source feeding into a fact or analysis appears on its own row; do not truncate or group entries. | Ref. in text | Source | Editorial/political line | Sourced element | Type (Fact / Analysis) | Publication date | Temporal consistency | | :--- | :--- | :--- | :--- | :--- | :--- | :--- | | E.g. Section 2 | Le Monde | Centre-left, general news | Q2 unemployment | Fact | 15/08/2026 | Contemporary with the claim — valid | GOLDEN RULE Prefer an incomplete, honest answer over an incorrect one. Never fill a factual gap with extrapolation, and never validate any causality or projection whose temporal chain has not been established.
