A childhood belief about lies

My mom liked watching a lot of Maury Povich and judicial shows when I was young and these shows always featured segments where lie detectors were used.

Consequently, I grew up thinking that lie detectors were so commonplace that every school, store, and police officer used them all the time. Because of this, I practically never lied as a child because I was scared someone would hook me up to a lie detector and prove that I was lying. As an adult, now I know better but even still, I find it very difficult to tell lies.
