If You Want to Catch a Liar, Make Him Draw

A man accused of a crime is brought into a police interrogation room and sits down at an empty table.  There’s no polygraph equipment in sight, and the typical two-cop questioning team isn’t in the room either.  Instead, one officer enters the room with a piece of paper and a pencil in his hands. He sets them in front of the suspect, steps back, and calmly says, “draw.” Read More

Dear David,

Thanks for the informative research on drawing and forensics. Having worked as an art therapist in the forensic arena with child abuse cases, what you said makes a lot of sense. Several years ago I worked with a couple of high profile homicide cases and drawing added the necessary confirmation of crimes committed.

While projective drawing tests continue to be suspect, we are learning that the process of drawing has other aspects that are noteworthy from a neuroscience perspective. Thanks for bringing this to light.

Kudos

Good article! Very practical and makes a lot of sense. Thanks!

Subjects

What subjects were included in the sample of the study?

I am unable to access the article, and it's not available through any of the databases to which I am subscribed.

The phrase you are looking

The phrase you are looking for is "by and large," not "by in large."

Good catch

Thanks

Unwilling suspects and results at group level

Since it's already hard to get people to talk during interrogation, it seems unlikely police officers are able to get a suspect to make a drawing.....

Besides, even if there is a significant difference between liars and truth-tellers, that doesn't help when it comes to the individual suspect. Still, you cannot be sure whether you are lied to or not!

Just wondering...an additional application

There was so much spinning and misconstrual during this election season. (TGIO) I wonder if getting people to map out their causality maps (say, when some expert proclaims that health care will wreck the economy) would make them more honest, too. Omissions and gross assumptions may become more apparent.

Thanks for your article.
