Illusory truth effect is widely used in a lot of areas.
Works involving illusory truth varies in different cognitive subject matters. For example, one would be the use of illusory truth in the the making of false memories (Polage, 2012) and another is when one reads a certain statement over and over again, it will then be perceived as true (Henkel & Mattson, 2011). Recent researches have also noted that illusory truths affect a person’s ability to easily comprehend statements. The repetition of statements make one’s understanding of it easier in comparison to new statements, which leads people to conclude that the repeated statements are more truthful (Unkelbach & Stahl,
2009).
There has also been other studies in regards to people having more knowledge to a specific topic and its relation to illusory effects. Researchers have questioned that would people with more knowledge about a particular topic show a greater or lesser illusory truth effect in that certain domain. The results of these subject matter differ from one another. Srull (1983) did a study wherein he questioned self proclaimed car experts and non experts questions about cars. The results of the study showed that car experts reflected a smaller illusory truth effect than those of the non experts. Another study on the other hand said that having expertise on a certain context increases one’s sensitivity of being influenced by the illusion (Arkes, Hackett & Boehm, 1989).
