This is a five-second test that can tell you whether you're a GOOD LIAR or not.  It's called the "Q" test.

Take your index finger and draw a capital letter "Q" on your forehead.

If you drew the "Q" with the bottom tail pointing left . . . so someone looking at your forehead would read it normally . . . that means you're aware of how other people perceive you, and you're a GOOD LIAR.

If you drew the "Q" with the bottom tail on the right side . . . so it would be backwards to someone looking at your forehead . . . that means you're more of an introvert and you're BAD AT LYING.
