Psychologist and author Richard Wiseman has developed a simple test to determine whether people are good or bad liars: a concept called the “Q” test.
The “Q” test is one of many segments in Wiseman’s book “59 Seconds: Change Your Life in Under a Minute”.
To begin the test, you point the index finger of your dominant hand and draw a capital letter Q on your forehead. Depending on which side of your head you draw the tail on determines whether you’re a good or bad liar.
If you drew the tail on the left side of your forehead so that it would be legible to others, then you’re aware of how others perceive you and are good at lying.
If you drew the tail on the right side of your forehead so that you could read it from your perspective, you are an introvert and a bad liar.
Since publishing his book, Wiseman has made a series of Youtube videos demonstrating the concepts he wrote about, including How to Lose Weight Without Trying and How to Never Lose Your Wallet Again. How to Tell if Someone is a Good Liar is his most recent.
