A delivery company tested a new routing system in its central district. During the trial, late deliveries there became less frequent. The first summary described the result as an improvement throughout the city. A reviewer initially accepted the sentence because the company's name appeared on every delivery vehicle. On rereading the methods section, she noticed that outer districts had not participated. She changed her judgment and narrowed the summary to the area actually studied. Another reviewer suggested claiming that the system would work equally well outside the center. She declined: outer districts had longer routes and fewer collection points, and no trial results were available for them. The company kept the positive central result while arranging a separate outer-district trial. Correcting the summary did not erase the observed improvement. It removed an unsupported extension and made the next research question explicit.
