Factors which contribute to the effectiveness of a corrective message are an individual's mental model, an individuals worldview beliefs, repetition of the misinformation, time-lag between misinformation and correction, credibility of the source and relative coherency of the misinformation and corrective message. Corrective messages will be more effective when they are coherent and/or consistent with the target audience's worldview beliefs. They will be less effective when misinformation is believed to come from a credible source, is repeated prior to correction (even if the repetition occurs in the process of debunking), and/or when there is a time-lag between the misinformation exposure and corrective message Additionally, corrective messages delivered by the original source of the misinformation will be more effective.
