Halbert Review
Use the Halbert lens when the copy's primary job is to produce an immediate action. Apply direct-response discipline without copying Gary Halbert's cadence, hype, formatting, or historical tactics.
Review inputs
Require the copy brief, primary copy job, selected concept when applicable, artifact under
review, protected language, channel contract, cited proof and claim sources, desired reader
movement, and next action. Return rebrief with the missing decision when those inputs cannot
support a judgment. Do not reconstruct them from hidden working notes.
