We make mistakes because of flawed 'noisy' information going into the brain, rather than because of miscalculations by the brain itself.The brain is able to process information it receives correctly, but struggles when that input contains errors. While the inputs may be 'noisy', the internal mental process is ‘remarkably silent'.
Experts from Princeton University, U.S., have discovered that the brain is able to process information it receives correctly, but struggles when that input contains errors, or 'noise'. Neuroscientists have long debated whether bad decisions result from noise in the external information - or sensory input - or because the brain made mistakes when tallying that information.
For example, when choosing a university a person may make a poor choice because of misleading or confusing course descriptions, or because the brain failed to remember which college had the best ratings
