Why Can Corrected Misinformation Still Shape Judgement?

Even when a report is clearly corrected and we remember the correction, the original claim can still shape how we explain what happened. Psychologists call this the continued influence effect of misinformation. It does not mean corrections are useless: research generally finds that belief falls, but the influence does not always reach zero.

In a classic experimental paradigm, participants read a sequence of reports about a warehouse fire. An early message said that paint and gas cylinders had been stored near the point of origin; this claim was later explicitly retracted. Participants could remember the retraction, yet still referred to volatile materials when answering inference questions such as why the fire had been so severe. One prominent explanation is that the misinformation had already supplied a coherent causal model. Removing it leaves a gap in the story, making the old explanation easy to retrieve again.

An effective correction should therefore identify the error clearly and, when evidence permits, offer a credible alternative explanation. If investigators establish an electrical fault, readers have material with which to rebuild the causal chain. An alternative must not be invented merely to fill the gap; when evidence is lacking, an honest “the cause remains unknown” is better than another unsupported story.

These experiments often use controlled narratives, while effects in everyday life also depend on source credibility, prior attitudes, repetition and correction timing. The finding does not simply show that people reject facts. It shows that updating memory and revising an inference are not the same step. After seeing a correction, it is worth asking whether your conclusion still depends on the claim that was withdrawn.
