Illusory truth effect
What is the illusory truth effect?
The illusory truth effect is a cognitive bias in which repeated exposure to an assertion increases the likelihood that it will be perceived as true, regardless of whether the assertion is actually true. This effect occurs because repetition makes the information more familiar, and people tend to view familiar information as more reliable.
How does the illusory truth effect work?
The effect works because repetition creates a sense of familiarity, leading to the belief that the information is true. This happens even when the person knows the assertion is false. Our brains interpret the frequency of repetition as an indication of reliability, making us more likely to accept the assertion.
An example of this effect
In the media, a false claim that is repeated often, such as in news reports or advertisements, may over time be seen as true by the public. For example, if a certain diet is repeatedly promoted as "the best way to lose weight," people may begin to believe it is true even if there is no scientific evidence for it.
