TLDR
Messages that check facts can reduce false beliefs, even when people strongly believe those errors. Their apparent success does not depend on one particular way of measuring beliefs.

1 Study Aim
The authors examine whether fact-checking messages (messages that evaluate claims and identify false information) reduce confidently held false beliefs. They also test whether conclusions change when researchers measure beliefs or analyze results in different ways. The study focuses on beliefs about immigration. The study asks whether corrections can change false beliefs, including strongly held ones.
2 Study Design
The research uses a two-wave, nationally representative online experiment involving beliefs about immigration. Participants received fact-checking messages, and the researchers examined belief changes across two survey waves. The authors used several theoretically motivated methods to measure inaccurate beliefs. They also accounted for belief certainty and compared different analytical approaches. The provided source does not report the sample size or specific message wording. The researchers tested corrections over time using several ways to measure and analyze people’s beliefs.
3 Findings
The study finds that fact-checking messages improve belief accuracy across different measurement methods and analytical approaches. The effects remain after accounting for how certain people feel about their beliefs. Corrections also affect participants who initially held inaccurate beliefs with high confidence. The authors conclude that researchers can have greater confidence in fact-checking effects despite measurement debates. They recommend that future correction studies examine measurement choices and belief certainty. The findings also support continued practical use of fact-checking efforts. Fact-checking can reduce even strongly held false beliefs, so researchers and practitioners should continue using and carefully evaluating corrections.
