The Illusory Truth Effect in Defamation: The Importance of Prompt Action

Perth Lawyer Richard Graham

In defamation, clients must be ready to act quickly and not dawdle.

Winston Churchill once observed: "A lie gets halfway around the world before the truth has a chance to get its pants on."

This statement holds particular relevance in the context of defamation cases, where the illusory truth effect can contribute to the rapid spread and entrenchment of falsehoods.

What is the Illusory Truth Effect?

The illusory truth effect is the feeling when we hear information that we believe it to be true, because we've heard it before.

The illusory truth effect is a cognitive bias that causes individuals to perceive false statements as true after being repeatedly exposed to them.

This psychological phenomenon underscores the power of repetition in shaping our beliefs and perceptions, making it a significant challenge in defamation cases where false information can become deeply ingrained in public perception.

First observed in a study by Hasher, Goldstein, and Toppino (1977), this psychological phenomenon highlights the power of repetition in shaping our beliefs and perceptions.

Several factors contribute to the illusory truth effect

  1. Cognitive fluency: Repeated exposure to information makes it easier for our brains to process that information, leading to an increased sense of familiarity and truthfulness.

  2. Confirmation bias: People have a natural tendency to favour information that aligns with their existing beliefs, making it more likely that they will accept repeated false statements as true.

  3. Source amnesia: Over time, people may forget the origin of the information they have encountered, making it difficult to discern whether the source was credible or not.

Implications for Defamation Cases

In defamation cases, the illusory truth effect highlights the importance of acting promptly when defamed.

The longer false information is allowed to circulate, the more deeply it becomes entrenched in public perception, making it increasingly difficult to restore reputations and refute claims.

The widespread use of social media and digital platforms can further amplify the effect, enabling false information to be shared and repeated on a global scale.

Strategies for Addressing the Illusory Truth Effect in Defamation Cases

  1. Acting quickly: When faced with defamatory statements, it is essential to take immediate action to mitigate the spread of misinformation. By responding promptly, legal professionals can limit the extent of reputational damage and challenge falsehoods before they become deeply ingrained.

  2. Fact-checking and providing accurate information: Thoroughly investigating claims and presenting accurate information can help counteract the impact of false statements. Demonstrating the inaccuracy of defamatory statements can help to discredit the falsehoods and restore the reputations of those affected.

  3. Educating the public and the court about the illusory truth effect: Raising awareness of this cognitive bias can help create a more discerning audience that is less susceptible to the influence of misinformation. This can be achieved through expert evidence, articles, and presentations.

  4. Emphasizing the credibility of sources: When presenting information in court, defamation lawyers should emphasize the credibility of their sources to counteract the influence of the illusory truth effect. Establishing the reliability of the information being presented can help challenge false beliefs and promote a more accurate understanding of the facts.

  5. Engaging in effective communication: Legal professionals should strive to communicate complex information in a clear, concise, and compelling manner. This can help ensure that the truth is more easily understood and retained by the audience, reducing the impact of the illusory truth effect.
