In movies it is shown that through polygraph test it can be found whether a person is lying or not. But we all know that it is not correct. What I am asking can the polygraph test be modified, more data collected so that it becomes more accurate ? Also is there any alternative to polygraph machine to find whether a person is lying ?
I think you can pass it if you ate chipotle right before the test, and the urge to go to the bathroom will normalize all the lies you tell
