Could this actually be accurate with such a simple test? Apparently you just need to hold up your first finger from your dominant hand.

You then go ahead and draw the letter “Q” on your forehead. Depending on which way you decide to tail off the bottom of the “Q” can tell you whether or not you are likely to be a good liar.

Before you pass it of as being totally sully, watch the video. It does sound pretty convincing. I have tried it out an am still not too sure.
