A neighborhood library tested reminder messages for two weeks. During the trial, books linked to reminders were returned earlier on average than books in the comparison group. The staff described an association, but they did not claim that reminders caused every early return. Weather, school schedules, and the kinds of books borrowed were not controlled. A local newsletter summarized the result as “The library proved that every reader should receive daily reminders.” That sentence kept the topic of reminders but changed the report in three ways. It turned an observed association into proof of cause, expanded a two-week pattern to every reader, and converted a description into a recommendation. The library corrected the summary to preserve the original verb, time range, and degree of certainty.
