How do you find out if someone is lying?

Maury

idk? ..i guess you just feel it deep down.

Start by asking them. If that doesn't help, investigate circumstances to see if the lie aligns with factual events and truth.

You ask them and if they say they're not you know you have them, but If they say they are then they're lying and telling the truth. Hope that helps.

Body language, and how the person chooses their words.

Intuition...👁

Check the facts

Hmmm I did research

Polygraph.

If it is a guy..mhis lips are moving.

Water board them

Dont assume.. you would just actually feel it. The best thing is gather evidence then ask. You would not know if you dont ask

Ask them the same question multiple times in different ways and see if the and pay close attention.

I can see it in their faces.

Fall in love with them give them your heart and it'll soon become apparent

Tickle them with a feather
