I'm trying to find out how to find out if a person is lying.

There are many different ways of doing this, but one way is to look for signs of stress or deception in the person's voice and body language. For example, when someone is telling a lie they may be more likely to have an increased heart rate and their face may show signs of discomfort. Additionally, certain words like "um" and "like" can also indicate that a person is not being truthful.
