Handwriting analysis could be new lie detection method

Jerusalem: Israeli scientist have found a
new way to catch liars -- by analysing their handwriting.

Researchers at Haifa University said that physical
properties of handwriting can tell whether he is dishonest.

"Handwriting analysis could eventually complement other
lie detection methods and would add a new dimension because,
unlike almost all other techniques, it doesn`t rely on verbal
communication," said lead author Gil Luria.

"This study adds writing with large strokes and applying
high pressure on paper to the list of telltale signs that
someone might be lying," Luria added.

The researchers could tell whether or not students were
writing the truth by analysing these physical properties of
their handwriting, the Scientific American reported.

"Lying requires more cognitive resources than being
truthful. You need to invent a story, make sure not to
contradict yourself," Luria added.

"Any task done simultaneously, therefore, becomes less
automatic. Tabletop pressure sensors showed this effect in the
students` handwriting, which became more belaboured when they
fibbed", she said.
