A correction is claimed to strengthen the false belief it targets.
Nyhan and Reifler reported it in 2010, and it was widely repeated. Later work, including their own, has largely failed to reproduce it — corrections usually help. A rare case of a bias entering common usage before failing replication.
In practice
- A manager corrects a rumour in an all-hands and watches it circulate for another month, though the more common outcome is that the correction quietly works.
- Treat the effect as unproven: the evidence now suggests correcting a colleague's mistaken figure usually helps, and the fear of backfiring is itself the more common error.
- Possible explanations
- The proposed explanation was motivated reasoning: a correction threatens an identity-relevant belief, so the recipient counter-argues and ends more convinced.
- In its favour
- The mechanism it proposed is real in other settings, since people do counter-argue threatening information, and the original studies were a serious attempt to test it.
- Against it
- It is rare in replication, including in the original authors' later work: corrections usually move belief in the right direction, so the strong version is unsupported and now serves mainly as a caution about how fast a striking finding spreads.
- Standing
- Rare in replication; corrections usually help, so the strong claim has not been supported.
