29 Mar Scientific study reveals the handwriting of a liar

A recent study published in Applied Cognitive Psychology by researchers, Gil Luria and Sara Rosenblum at the University of Haifa, with the aid of a system called ComPET (Computerized Penmanship Evaluation Tool) which is a piece of paper on a computer tablet with a pressure-sensitive wireless pen, discovered that people who are writing lies press harder on the paper and produce taller letters than those who tell the truth.
The participants were asked to write two paragraphs on the ComPET; one paragraph describing a real event and in the second paragraph, a false text. The results were not easily visible to the naked eye but the program detected differences in the two samples.
Graphology goes as far back as Aristotle when he said:
“Speech is the expression of ideas, thoughts or desires. Handwriting is the visible form of speech. Somewhere in handwriting is an expression of the emotions underlying the writer’s thoughts, ideas, or desires.”
The first published reference of handwriting analysis was in the 17th century with Camilo Baldi’s treatise called De Signis ex Epistolis (1622). Later in 1904, the psychologist Alfred Binet (France) affirmed the reliability of handwriting analysis in a published study and later developed the first standardized IQ test.
In New York, Edgar Allan Poe also analyzed handwriting and published some of his analyses. He used the word “autography” to describe his research which was published in 1926 as a book by Dial Press of New York. Later in 1955, Klara Roman and George Staemphli developed a checklist that organized certain factors and plotted them on a chart called a graphological psychogram. This system of handwriting analysis was developed by Klara G. Roman, during her tenure at the New School for Social Research in New York City and was later refined by Daniel S. Anthony .
It’s interesting to note that Graphology books moved from the occult category and were accepted into the classification of the U. S. Department of Labor in psychological and personnel categories of
Dewey Decimal Classification at the Library of Congress in 1979.
Though the results of the Haifa University study were not visible, there are visible handwriting clues that indicate someone is prone to lying.

In any case, the ComPET program is probably a lot cleaner but maybe not as clever as this ancient Chinese lie detector:
“Dried rice was placed in the mouth of suspects, and when they spit the rice out, they were considered guilty if they still had rice sticking to their tongue. This approach has some scientific validity: Persons under stress tend to have a dry mouth and can’t produce enough saliva to spit out all the rice and a guilty person would presumably be under more stress in such a situation than an innocent.” Schafer, Elizabeth D. (2008). Ancient science and forensics (Wikipedia)
