Do your shifty eyes really say you're lying? Not according to the latest theory - they merely reveal that you're thinking hard and accessing your long-term memory.
Rapidly moving eyes have long been thought to show we're either disinterested or telling a porky.
Researchers behind the latest theory, have been studying eye movements since the 1970s and say fast eyelid twitches disengage a person's focus of vision, so that it often moves down and away from the questioner.
Animals in the wild continually survey the surrounding landscape for food or danger and when they find what they are looking for, they focus on it, adds the leading scientist.
Although our eyes aren't required for searching our internal memory, they operate in the same way they would in the physical environment by 'going along for the ride'.
If the answer to a question is simple, we don't have to disengage our visual focus and our eyes won't be 'shifty'.
It's a theory that'll have me watching the eyes of interviewees on the TV even more carefully!
