Lying is a natural human trick.

It lets you manipulate the way you want others to see you.

There are certain signs you can look for if you think someone might be lying to you.

Eye movement.

When right-handed people are lying, they look up the right, left-handed people look up to the left.

Other signs of lying are: if they don't blink, close their eyes very slowly or contrastingly blink a lot or break eye contact.

Hiding body parts.

They hide their mouth, eyes or throat with their hands.

Grooming.

They may also adjust their hair or clothes.

Hand movement.

Anxiety can cause itching or chilliness in the face, causing a liar to bite or lick their lips or play with their ears.

Head movement.

They move their head around quickly before they answer the question.

Audible cues.

They clear their throat or swallow before answering the question and their vocal pitch rises.

Yeah.

No ...
