A video on YouTube's in 59 seconds channel has an interesting video which offers a quiz that tells if a person is a good liar or not.

According to research from psychologist R. Glen Hass, it's all about extroverts versus introverts.

People who draw the letter in a way that could be read by someone else facing them are more likely to be aware of how others see them. These people tend to extroverted, and thus better at lying. But people who draw the Q facing so that they themselves can read the letter are less likely to know how other people view them, and are more introverted. These people tend to be worse liars.

So before you tell your boss that you're late due to a flat tire, take five seconds to test your fibbing skills.
