The Eyes Lie...
So a common misconception that a lot of people have about reading body language is the eyes. The belief is that if someone doesn't look directly at you they're lying. If they look off to the right, they're lying. If they look up, they're lying. That's all incorrect!
First of all, your eyes do tell a very interesting story about what may be going on in your head but to accurately interpret eye movement you must know a little bit about the person.
As you think and speak, your eyes move and we call this movement your eye-scanning patterns. Through years of research, it's been agreed that the eye-scanning patterns are symptomatic of the brain's attempt to access internally stored or internally generated information. All of this information sitting in your head is "encoded" through one or more of the "VAK representational systems."
So what's happening when your eyes move?
What's going on when they flicker and begin to scan?
When a person “goes inside” to retrieve a memory or to create a new thought, they exhibit certain behaviors indicative of the representational system they are accessing at that moment. Keep in mind that these are generalizations based on casual observation only. Many eye movements happen too fast or almost too fast to track.
Most people (an estimated 90%, based on non-scientific observation over the years) are organized according to the following chart. The rest are organized in some other fashion, commonly the direct left/right reversal of the chart. No one knows why this is the case.
These cues help demonstrate which sensory representation system the person is currently accessing: visual, auditory or kinesthetic (including gustatory and olfactory).
VR – Visual Remembered: When people look up to their left, they are generally accessing pictures they have actually seen before; e.g., the color of their first car
AR – Auditory Remembered: When people look sideways to their left, they are generally hearing something they have heard before; e.g., a piece of music they may have heard, or their mother’s voice.
AD - Auditory Digital: When people look down to their left, they are generally talking to themselves in their own voice.
VC – Visual Constructed: When people look up to their right, they are generally constructing images they have not actually seen before; e.g., an orange with purple spots.
AC – Auditory Constructed: When people look sideways to their right, they are generally hearing something they have not heard before; e.g., a piece of music they are creating for the first time, the sound of a glass bell.
K – Kinesthetic: When people look down to their right, they are generally accessing emotions or bodily sensations.
So what does all of this mean?
It means that even though they may not look at you, they may look around, they may be doing something completely strange with their eyes, it is not a 100% way to catch them in a lie. When someone access construct, it doesn't necessarily mean they are lying. For instance, if I asked you to describe a pink elephant, you will immediately go to visual construct, not because you are lying, but because you've never seen a pink elephant. Now if you go to visual recall, at some point, you've seen a pink elephant and you are bringing back the image to describe to me.
In short, in order to understand if they are lying or not, you'll need to learn a little more about the person before you make snap decisions
