A new study adds “writing with large strokes and applying high pressure on paper” to the list of telltale signs that someone might be lying.

Lying requires more cognitive resources than being truthful, says lead author Gil Luria. “You need to invent a story, make sure not to contradict yourself, et cetera.” Any task done simultaneously, therefore, becomes less automatic. Tabletop pressure sensors showed this effect in the students’ handwriting, which became more belabored when they fibbed.
