Does misinformation continue to influence political attitudes even after it has been effectively corrected? According to some influential studies, the answer is yes: while corrections may eliminate belief in false claims, they often fail to erase their attitudinal impact – a phenomenon known as “belief echoes.” To evaluate this claim, we conducted a preregistered, high-powered replication of two out of three experiments from a widely cited study which introduced the phenomenon, using the same treatment materials and a much larger, more representative sample. In the first experiment, the correction did not fully dispel belief in the misinformation, making it impossible to isolate a belief echo from the direct effects of continued belief. In the second, where the correction was demonstrably effective, we find no evidence of a lingering attitudinal effect.
