Fun Fact Friday!

Good afternoon to everybody. I hope that everyone has had a safe holiday season so far, and are excited for the snow to come! And with the snow, comes Christmas, and with Christmas comes Santa Claus. We all know that Santa can tell who's been naughty or nice, but how do we tell when someone has been lying, if we're not Jolly Ol' Saint Nick? We rely on a little invented called the polygraph test, also known as the lie detector test. Now there is some debate as to how legitimate the polygraph is; some swear by it, yet it's rarely used as significant evidence in the legal system, no matter how perfect it works on CSI. It makes it's readings by measuring the perp's blood pressure, pulse, respiration, and galvanic skin response(I have no idea what that last one is). This system was created by Dr.'s John A. Larson and Leonard Keeler in the 1920's. However, the lie detector concept was made popular in WWI when Dr. William Marston was hired to use his blood-pressure based tests, to see if prisoners were telling the truth when being interrogated. For all of you comic book lovers, yes, it is the same William Marston who created the character Wonder Woman.

Enjoy the holidays, and PROUST.
