How To: Access Someone's Thoughts Using Only Their Eye Movements

Look away from this screen and try to remember the sound of your childhood hero's voice. Did you do it? Do it again, and this time pay attention to your eyes.

There's a good chance your eyes stayed centered as you decided on who your hero was, moved slightly up and to your left when you visualized them, and then moved slightly down and to your right when you imagined their voice.

I know this not because I've hacked your webcam, but because your eye movements are intimately tied to certain areas of your brain. Let's use this fact, along with our previous tips on spotting liars, to access other people's thoughts.

Practice on Yourself First

Before going into any details, test your own eyes and get an understanding of how they're connected to your thoughts. Address the following and take note of even the slightest eye movements up, down, or to the side.

1. What did your worst haircut look like?
2. What will your city look like in twenty years?
3. What's the most annoying '80s song and how does it sound?
4. Write a jingle in your head.
5. Have a short conversation with yourself.
6. Imagine the feeling of a warm bed on a cold day.

The first two questions likely sent your eyes upwards, while questions three and four moved them to the side, and the last two cast your eyes downward.

#1. Upper Left - Visual Memory

Unless the memory is immediately available, someone's eyes looking to their upper left tells you that they are accessing an image of something from the past. This is a familiar position for those who are visual learners and rely on a visual memory.

#2. Upper Right - Visual Construction

Eyes looking up and to the right indicate that the person is constructing a visual image in their mind. People who are lying will look in this direction as they fabricate mental images. Of course, Samuel L. Jackson explains it best.

#3. Lateral Left - Sound Memory

When your dad tries to remember the punchline of a terrible joke, his eyes are probably looking to his lateral right. This direction indicates that a person is trying to recall a sound from the past.

You can use this to assess whether or not someone is reciting lines when they claim to be sincere. Children often look in this direction, for example, when they're repeating the political and religious rhetoric of their parents.

#4. Lateral Right - Sound Construction

If someone is lying about a conversation they claim to have had, they'll look to their lateral left. This direction indicates the creation of sound.

#5. Lower Left - Inner Dialogue

The devil isn't really on your shoulder, he's on your left collarbone. If someone is having an internal debate, they'll likely glance to their lower left. This area indicates a person is deep in thought or questioning.

#6. Lower Right - Kinesthetic/Feeling

Remembering the feeling of something will push our eyes to our right. Don't believe me? While your eyes are closed, move them to the upper left and try to imagine the feeling of fur. The try it with your eyes to the lower right. Which one feels less awkward?

The Potential Complications

Obviously this method of prediction is not foolproof. Eyes are rarely held static in one position. Environmental stimuli like noise and light will influence the direction of eye movement, as will the pressure to maintain steady eye contact in a conversation. Instead, look for repeated "flickering" to any side.

Preferred Representational Systems

Every individual has a preferred way of representing information in their mind, which will influence the direction of their eyes. Some prefer visual images and others prefer sound.

If you ask someone to describe what they saw, for example, they will access their memory of the image (eyes to their upper left), but may also construct a description of the image in their head (eyes to the lateral right).
