If you want to find out the truth, hand your potential liar some crayons. A study in Psychology Today says liars have a harder time drawing a scenario than telling a lie.
The best way to tell if the picture is not true is the angle in which it is drawn. Liars tend to draw a situation from an overhead view while people telling the truth have a shoulder-camera perspective . Liars also tend to draw simple pictures; it’s a lot easier to make up details verbally.
The drawing test identified 80 percent of truth-tellers and 87 percent of liars.
