Summary

Debunks the viral "only 0.2% of Tennessee welfare applicants tested positive for drugs" story: the "drug test" was a written question asking whether you use drugs, so all it really shows is that ~0.2% are too impaired to tick "no" - while real data show poor people use drugs as much as or more than average. Florida's earlier urine program looked similarly damning only because applicants paid up front and were reimbursed if clean, which selected drug users out. The broader lesson: fudging numbers even for a good cause makes the truth your enemy forever.

Why this score

Quality 68 · Strong. A satisfying media-debunk with a real methodological core (selection effects; the "written test") and a sound anti-fudging principle, but topical and narrow. Strong.

Claude’s paradigm shift 25 · Slight. A sharp application of selection-effect reasoning plus a restated principle; no new concept. Slight.

Real-world impact 2 · Minor. A topical media-debunk of the welfare-drug-testing statistic with a real selection-effects core; corrects the discourse but produces no policy or material-world change → RWI 2.
