Show the evidence
Keep the limits visible

TALLYCAT01 investigates the claims shaping public opinion. The aim is to make the evidence understandable enough for you to assess it yourself.

Start with the exact claim

What was said, by whom and when? We preserve the original wording where possible, check the surrounding context and separate claims that need different evidence. A wrong location and an allegation about who caused an event need separate checks.

Follow the source

We prioritise original statements, documents, datasets and recordings. When information comes from another outlet’s interview or reporting, we name that outlet. A source saying something is evidence of its position, but may not prove the underlying claim.

Understand our labels

By the numbers explains scale and the quality of numerical evidence. It distinguishes measured counts, estimates and gaps in the data. It makes no assumption about deception or whether a policy is justified.

Misleading framing is a specific type of misleading content. We use the orange label when the underlying facts are supported but their presentation gives a materially distorted impression. We show the missing context and explain what it changes. It is not evidence of intention.

We assess accuracy and intent separately. An error does not prove deception. An official denial does not automatically disprove an allegation. A numerical explanation can use By the numbers without assigning a truth or intent verdict.

Make numbers explainable

We identify the population, period, units and comparison behind a number. Where analysis is involved, the article should explain the result directly and provide the source data or calculation file for readers who want to inspect it. We distinguish measured counts from estimates and missing data. A figure rounded to 0.00% does not establish zero cases. A rare problem is not automatically harmless, and its rarity alone does not settle whether a policy is justified.

Leave a route you can repeat

Every investigation includes numbered steps showing what to open or download, where to look and how to compare the result. We link the original sources and provide a downloadable guide. A source we cannot reopen is marked as a limit, not treated as a completed independent check.

For data analysis, the guide should identify the dataset and version, fields, filters, exclusions, units, denominator and calculation, with the expected result. Published tables and charts do not imply access to individual responses. We provide data or workbooks only when we have them and can share them.

Try it yourself: repeat the Luton checks or rebuild the Downpatrick chronology.

Use pictures honestly

Archive photographs are labelled as archive context. They do not establish current conditions or place people at an event. We use authentic photographs with checked reuse rights, identify the photographer and link the applicable licence.

Evidence can change a finding

If you spot an error or have relevant new evidence, email TallyCat_01@hotmail.com with the article link, the point at issue and a source we can check. Substantive corrections should be explained on the affected article with the date and what changed.

AI assistance

Research and production are assisted by AI. AI output is not a source. Articles link the underlying evidence and disclose material verification limits.
