XIXCognitive Bias
Illusory Truth Effect
Your bias is Illusory Truth Effect. Repeated statements feel truer regardless of accuracy.
Why This Bias Happens
Fluency is mistaken for truth. Repetition lowers processing effort, and ease is falsely read as reliability.
Example 1
Seneca warns that constant public applause can deform judgment. Familiar slogans may soothe, but they do not prove.
Example 2
Experiments on repeated trivia statements found that repeated falsehoods are judged more believable over time.
