10 predictions · 2 assertions · 10 opinions · 26 insights · 7 disclosures · 1 what if · every statement was checked. The predictions and assertions are the 12 claims: statements the public record can support or contradict. 1 is resolved, 1 is not yet assessed, and 10 name no date, number or outcome precise enough to check. Everything else (opinions, insights, what ifs, disclosures) can never be settled by the record, so it carries no assessment.
