M'kay i don't know how to break this to you but when you go in the light or dark your pupil size changes and has nothing to do with you lieing
this doesn't work
Not necessarily. When people lie the body reacts different ways because of naturaly being nervous. I know when my cat gets all jumpy, skiddish and/or nervous when it's stormy out or I startle her her pupils get big and dialated.
Blood pressure may rise, heart rate my increase- it's been tested and proven things like this happen in the body when people lie.
Although it may or may not be true in all cases, just because something is caused by one thing doesn't mean it can't also be caused by another thing, too.
