This study explores how the strength of misinformation encoding and subsequent corrections (retractions) influence the persistence of misinformation effects on memory and reasoning. Participants read an event report containing misinformation and a correction, with encoding strength manipulated through repetition or cognitive load in two separate experiments. The findings indicate that while strong corrections can mitigate the influence of well-encoded misinformation, they are less effective against the lingering effects of weakly encoded misinformation, suggesting that the continued influence of misinformation is resilient to corrective efforts.
