Pinochio lie detector... WHY????
I have done the "Pinochio lie detector tests". Analyzing my conclusions i have noticed that when a person is lieing the arm is not as resistant as when the person is telling the truth. And if anybody could answer me, WHY????? it would seriously be a great help. Thank you !!!!

Hello,
First of all, congratulations on choosing this project, it is a great and fascinating one.
As to whether the arm is not as resistant when the person is lying can be simply explained by the fact that it has been shown that a person lying has its brain working much harder that a person telling the truth. Holding up one's arm is also a task controlled by the brain. So if someone is lying, its brain will be less focused on the arm and more and lying.
You can find a more detailed explanation on the page of the science buddies project, as well as references:

I hope this helps, let me know if you need anything else!
