Im doing a science project: Can body language help you determine if a person...

...is lying? This is my conclusion so far: In conclusion, my hypothesis that body language can, indeed, be a big help in determining whether or not a person is lying was proven correct. Despite the fact that no type of body language suggests ultimate proof of lying, I did background research on body language before experimenting, only to find that during my experiment, many of the surveyed students displayed at least one of these changes when they began to lie.
When a person lies, they’ll normally feel uncomfortable about it, and their displayed gestures will conflict with the words coming out of their mouths. Some people may give away their signs of lying without even realizing it. The body language of lying varies from the ever so tiny curling of the lip to excess and unnecessary laughing.

Also, when one tries to hide their falsehood, they tend to not wish to look the opposite person in the eyes. Detectives use subtle body language like this in their profession to perceive whether a suspect is lying or not.
