Pinocchio Had It Backwards: When You Lie, Your Nose Shrinks

November 12, 2018

So I guess "Pinocchio" wasn't a documentary, because it got its facts TOTALLY wrong. According to a new study out of Spain, when someone lies, the blood drains out of their nose, which makes it about two degrees colder so it contracts. That's right, "Pinocchio" had it backwards your nose slightly SHRINKS when you lie.

So where does that blood go? Your forehead gets about three degrees hotter, which means it gets bigger when you lie. Which might be why I always think Christian Slater is lying.
