Your brain believes repeated information because it relies on mental shortcuts to process the massive amount of data it receives every single day. It prioritizes efficiency over absolute truth. This psychological phenomenon is known as the Illusory Truth Effect.
Repeated information is easier for your brain to process. The brain mistakes the physical ease of processing for truth.
In nature, familiar things are usually safe, while unfamiliar things are dangerous—the human brain has an evolutionary bias where familiarity signals security.
Also, repeating a thought strengthens the physical neural connections (synapses) between neurons. This turns the thought into an automatic habit.
Furthermore, fact-checking requires active, energy-consuming critical thinking. The brain prefers to save energy by accepting familiar data.
Because of this wiring, constant exposure to misinformation from negative self-talk gradually reshapes what you accept as fact. To counteract this, you must actively and intentionally repeat truths you want your brain to adopt.
