A method for enhanced graphological detection of deception is disclosed, including collecting handwritten answers to control questions and test questions from a subject. In certain embodiments of the invention, the collection of answers is accomplished with a handwriting tablet that can provide digital output. Next, the control input is analyzed so as to generate control handwriting feature data, and the test input is analyzed so as to generate test handwriting feature data. Next, test handwriting feature data resembling control handwriting feature data is designated to be non-deception-related, and test handwriting feature data not resembling control handwriting feature data is designated to be potentially deception-related. Finally, potentially deception- related test handwriting feature data is analyzed using graphological analysis, thereby identifying deception-related test handwriting data, and deception data is generated therefrom. A system for executing the method is also disclosed, which in some embodiments is a computer system.
