How a score is built

The inputs, the weights and what a score can and cannot tell you.

A score in 7Analytica is an estimate of how well the evidence stands. It is not a verdict. It is printed with the inputs that produced it so you can disagree with the weighting and still use the record.

The inputs

• Source reliability: the source's measured record, with its sample size and last review date.
• Corroboration: the number of independent origins, not the number of outlets.
• Recency: how recent the reporting is relative to the event.
• Primary documents: whether a document you can open supports the claim directly.
• Framing neutrality: how far the wording departs from how other reports describe the event.

What the number means

A higher number means the evidence behind the claim is stronger on these inputs. A lower number means it is weaker or thinner. A low score on a true claim is possible: it means the evidence we hold is thin, not that the claim is false.

When a score moves

New evidence changes a score. The entry that moved it is listed with its time and the earlier value is kept. A sealed record does not change; later movement appears as a new entry.
