The Psychology Behind Repeated Lies and Misinformation

The act of lying is as old as human interaction, but the repeated exposure of a lie can make it seem like the truth. This phenomenon, known as the 'Reiteration effect' or 'Illusory truth effect,' can significantly impact how we perceive information. Joseph Goebbels, the Nazi propagandist, eloquently encapsulated this concept with the quote: 'Repeat a lie often enough and it becomes the truth. A lie told once remains a lie but a lie told a thousand times becomes the truth.'

Understanding the Reiteration Effect

The reiteration effect, or illusory truth effect, is a cognitive bias that causes people to believe in the validity of a statement the more often they hear it, even if it is false. Despite the rationality of the mind, familiarity can overpower rationality. In this article, we will explore the psychological underpinnings of repeated lies and how they become entrenched in our belief systems.

Why Lies Become Beliefs

When a lie is repeated, it plows a path in our belief systems, making it easier for us to accept it as the truth over time. The more exposure we have to a statement, the more likely we are to believe it, regardless of its veracity. Even a small piece of knowledge, coupled with repeated exposure, can solidify a lie in our minds.

Examples of Repeated Lies

A notable example occurred during the COVID-19 pandemic. False information regarding the virus would circulate on social media platforms, often via groups like 'Whatsapp University.' Despite these sources being unverified, people shared these messages repeatedly, believing them to be true. This method effectively repeated the lie until it seemed like the truth to many individuals.

Personal Misinformation Example

Repetition can also distort our reality in more subtle ways. Consider this: I know that it snows in Canada during the winter. Given that Vancouver is in Canada, I confidently assert that 'It snows in Vancouver.' However, my friend Kabir informs me that this is not true. I consult various geographically inclined sources, and despite being told that it doesn’t snow in Vancouver, the constant repetition of the lie convinces me of its truth, even though I never checked any credible source to verify the claim.

Rationality vs. Familiarity

Rationality often takes a backseat to familiarity. When we are bombarded with information, even if we know it is false, the repeated exposure can override our rational judgments. For instance, when presented with conflicting information, such as being told that it snows in Vancouver versus it doesn't, repeated lies can lead to confusion and a dismissal of rational analysis in favor of the more familiar.

The reiteration effect often works on a subconscious level, making it difficult to differentiate between truth and falsehood, especially when the information is repeatedly presented as factual.

Implications of the Reiteration Effect

The implications of the reiteration effect are profound. In places like politics and journalism, repeated lies can shape public opinion and perception. Understanding the psychology behind it is crucial for individuals and organizations to counteract misinformation. Education about critical thinking and the importance of verifying sources can help mitigate the impact of the reiteration effect.

Conclusion

The reiteration effect or illusory truth effect is a powerful cognitive bias that can lead to the acceptance of falsehoods as truths. By understanding this phenomenon, we can better defend ourselves against the spread of misinformation. It is important to verify information through credible sources and to question the information we absorb, especially when it is repeatedly presented to us.
