Add a second look when errors carry forward
Review is worth separating when an output will guide later work, shape a public claim, change a shared process, or become a reusable source. The reviewer needs the same task boundary, selected evidence, and intended audience as the writer.
The job remains small. Source notes enter. A content brief comes out. A different pass checks the brief against the notes, fit, scope, and stated limits. The writer then corrects the brief or records an unresolved question.
Stop when each material statement has support, every addition stays inside the task, and the final brief makes uncertainty visible.
Follow one visibly synthetic review
The initial workshop brief says, “Saturday sessions are available.” The source note confirms independent consultants, a two-hour planning session, and a requirement to use confirmed details only. It contains no schedule.
Independent review names the unsupported sentence and requests removal. The corrected brief keeps the confirmed details and leaves schedule and price undecided. The checkpoint preserves both brief versions and the finding.
This example proves only that the review method can expose a source mismatch in the sample.
Know when separation will not help
A second pass fits work where another perspective can test evidence or consequence. It does not help when the reviewer sees only the polished output, repeats the same assumptions, or lacks authority to name a problem.
For low-consequence scratch work, rereading against the source may be enough. For consequential decisions, review may also need a qualified human who understands the domain.
