The Illusion of Truth Effect is a cognitive bias where repetition increases the perceived credibility of a statement, regardless of its accuracy. In online communities, this bias can lead to the spread of misinformation as frequently repeated claims gain trust over lesser-known facts. This can skew discussions and make fact-checking more challenging.
Community managers can address this bias by promoting critical thinking and ensuring access to credible sources. Highlighting verified information and questioning frequently repeated but unsubstantiated claims fosters a more informed community.
In a health forum, a repeatedly shared myth about a treatment might gain unwarranted trust. Moderators can intervene by sharing scientific evidence and redirecting discussions to accurate information.
