There is a theory out there that positive reinforcement increases muscle strength and negative reinforcement takes it away. It does appear to actually have some foundation to it. You can experiment on a friend- have them hold their arms out and ask them to say their name. They should hold up strong. Ask them to hold their arms out and tell you a lie. Most people's arms will fall further than they did when telling the truth.
It is weird.
And I like Metallica.
