The publisher analyzed citation chain depth across 20 domains

We used LiquiChart's claim extraction pipeline to identify every monitorable claim in each post, statistical, comparative, source-citation, and temporal. Numbers, ratios, percentages, and dated assertions all qualified, since a "2024 survey" reference is as falsifiable as a "67%" reference. From there, we traced each chain from the citing post to its terminal node. The process was mechanical: follow the citation link, determine whether the cited page contains the asserted value or date, and if it does, check whether that page cites a deeper source.
