Statistical forensics engine

Impossible numbers,
proven in seconds.

Statlint reads the statistics in any research paper and mathematically proves which reported results cannot be real — seven peer-reviewed forensic methods, unified into a single report.

The problem

Science has a numbers problem.

Papers report means no dataset could produce, standard deviations that break algebra, and p-values that contradict their own test statistics. Almost none of it gets checked — reviewers and editors have neither the time nor the tooling.

How it works

Paper in. Verdict out.

01 / INPUT

Drop in a paper

Paste a results paragraph or upload a PDF, JSON, or CSV. Processed in memory, never stored.

02 / ANALYZE

Run the battery

Seven forensic checks recompute and cross-examine every number the paper reports.

03 / REPORT

Read the evidence

Proven impossibilities first, heuristic flags separated, each explained in plain English.

The battery

Seven methods, one verdict.

Five return mathematical proofs of impossibility. Two return heuristic flags. Statlint never conflates the two.

The discipline

Proof, never accusation.

Statlint draws a hard line between a mathematical impossibility — proven, the numbers cannot all be right — and a statistical suspicion, a flag worth a second look that proves nothing on its own. The engine is validated against thousands of real datasets to guarantee it never flags genuine data. Every finding is a question to put to the authors, not a verdict on them.

Impossibility mathematically proven
Suspicion heuristic, unproven
Coverage

Every field that reports statistics.

The methods are field-agnostic by construction — if a paper reports means, SDs, p-values, or test statistics, Statlint can check it.
