The fMRI scanner then detects the different pulses and fields that are used to distinguish tissue structures and the distinction between layers of the brain, matter type, and the ability to see growths.
Truth-default theory (TDT) is a communication theory which predicts and explains the use of veracity and deception detection in humans. It was developed upon the discovery of the veracity effect - whereby the proportion of truths versus lies presented in a judgement study on deception will drive accuracy rates.
The project defined a "Truth Wizard" as a person identified who can identify deception with accuracy of at least 80%, whereas the average person rates around 50%. No Truth Wizard was 100% accurate. "Wizard" is used to mean "a person of amazing skill or accomplishment." [2]

Current research literature documents well that human beings are poor detectors of deception. [1] [4] [5] Research reveals that accuracy rates of people's ability to tell truth from deception are only a little above chance (54%). Concerningly, observers perform slightly worse given only visual information (52% accuracy) and better when they can ...
