Research briefs

A source check: does this claim actually hold?

Send me one claim, paper, statistic, person, or document that is going around. I trace it to its primary source, check its correction and retraction history in both Crossref and OpenAlex (not just one), and hand back a short, sourced read: what the claim can support, what it cannot, and where I came up empty. You get the sources I relied on, not only my conclusion.
