Eyes are not just a mirror of the soul, but can aslo reflect what we think in some situations. If you want to know what your interlocutor thinks, do not follow the position of the body, but the position of the eyes … By observing eyes you can discover how a person feels, how sincere is he and what he thinks. Scientists have discovered that the position of the eyes can reveal what a person thinks. Throughout the experiment, participants were asked to imagine the number, and scientists were suppose to decipher what number was on their mind. Tracking of the eyes allowed them to in many cases guess which number were they thinking about. Watching to the left shows that people think of a smaller number, while watching to the right shows that this is a big number.
Of course a lot more analysis needs to be made to deciphered complex thought, but scientists believe it is possible.
