The sequence makes the distinction do work on an already familiar problem. The return also complicates the first obvious explanation that the price was simply too low.

“Try to tell the difference…”
The reader receives both visible inputs and intermediate reasons. The invitation to guess is supported by an explanation of what to look for; it is not an unprepared puzzle followed only by the researchers’ authority.

“some non-cheaters were needed as a control group…”
This makes the choice of comparison intelligible. The reader can see why a decrease in one group alone would leave an alternative open and why the controls matter to the inference.

“different incentives…”
The apparent contradiction becomes a consequence of interacting positions. The explanation advances beyond the opening wage puzzle to account for conflict inside the hierarchy.

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.
