The Illusory Truth Effect is a phenomenon in which people tend to believe something is true simply because they have heard it multiple times. It is a cognitive bias that can lead to logical fallacies and can be seen in people of all ages, including children. For example, if an 8-year-old hears the same statement more than once, they may start to think it is true, even if it isn't.
Illusory truth effect, cognitive bias, logical fallacy, repetition bias.
