The screen turns an abstract warning about bias into a visible design decision: preserve the sound relevant to the task while withholding an irrelevant cue. That concrete procedure gives the final generalization an image the reader can retain.
The ending gives the discipline argument a visible action under deliberately arranged information and timing conditions. Its last image recalls the protected routine established at the start of the chapter, so the financial milestone is followed by a concrete enactment of the narrator’s principle.
Reviewed examples have a source-linked editorial interpretation. Detected candidates are exact passages or structures retrieved by an explicit rule and still need interpretation. Neither label establishes a cause of bestseller longevity. No missing text is counted as a negative example.
