Disputed The provided passage is only a bibliographic line and does not contain the quoted text; it also conflicts with reliable metadata, which tie the Science URL/title to Jon Cohen, not David Grimm, in mid-March 2026. I could corroborate the article’s existence and theme via Jon Cohen’s own post and third-party feeds, but accessible excerpts use different wording about the maps and I found no reliable source containing the submitted sentence verbatim.
