Method

We judge claims of expertise by evidence that can be traced, not by reputation. Every result carries a verdict, a confidence level, and the limits of what it does not prove.

Five steps

1. Record the claim. Quote it, and where and when it was made.
2. Check the credentials. Ask the issuer (university, institution) and check the official databases available.
3. Gather evidence. Each item is written up with what it shows and what it does not prove.
4. Give a verdict. One of the four below, with a confidence level.
5. Open the right of reply. The expert named can respond; replies are published as received.

The four verdicts

• Confirmed: the credential issuer or a primary source supports the claim.
• Partly: part of the claim is supported, part is not or differs from what was stated.
• Not supported: the sources that should exist were sought and do not support the claim. This is not a statement that the claim is certainly false.
• Cannot yet be verified: no source could yet be reached or found; we are waiting for confirmation.

Confidence

Low: few sources or only indirect ones. Medium: several sources that agree. High: primary sources and direct confirmation.

Limits

What this site publishes is the author's opinion and notes, not a court ruling. Everyone has the presumption of innocence and the right of reply.
