Record available
In the research rounds of 28 and 29 September 2026, which steps of Lighthouse's research and review workflow changed what its pieces and records say, what kind of change did each make, at what cost, and what reached release uncaught?
The question
Which research and review steps changed Lighthouse’s claims, at what cost, and what passed through to release?
What the record says
Across six rounds, 66 of 125 recorded changes altered what readers would believe: evidence review most often changed figures or certainty, while changes to meaning came mostly from reader review and outside review relayed after release, a grouping made after the counts. Eight of ten public-claim changes at recheck corrected text just written to resolve an earlier review.
