- The first sign is the eyes.
When the brain is creating
a mental picture the eyes
instinctively move up and
to their right (your left),
signifying access to the
right hemisphere (creation)
and visual cortex (pictures).
This usually means they
are constructing a picture
in their head. If someone is
recalling a picture (remem-
bering something that they
actually saw) then they
would look up and to their
left (your right). - The eyebrows rising
towards the centre of the
forehead (where the arrow
lands in the picture) is a
sign of fear. This sign can
occur during or immediate-
ly after a lie, because they
are scared that you will see through it. - Another sign of fear is the sides of the lips turning down. The muscles that control this action are
very specific and it is almost impossible to consciously activate them without activating any other lip-
related muscles. - This is my favourite sign, when someone touches their nose or lips, covers their mouth or in some
way touches their face during the telling of a lie. It is very common and is the expression of an urge to
conceal themselves or look casual while misdirecting your attention.
Other Signs That Someone May Be Lying
The four signals above are not 100% accurate - it is possible for a good liar to prevent any of these
signs occurring while they tell a lie. Sometimes, a liar is so talented that they can actually convince
themselves that they are telling the truth, therefore a lie may appear entirely genuine. But it requires
great effort in the brain to convince yourself you’re telling the truth, and those cranial efforts have
footprints.
