A bizarre trick shown by the celebrity psychologist Richard Wiseman that explains a technique to find whether your partner is a good liar of not.
He explained the trick in video by saying “extent the first finger of your dominant hand and taking just five seconds, trace a capital Q on your forehead”.
He then said that if the tail of traced capital Q is in left side of forehead then your friend is a good liar.
But if the tale of traced Q stays on right side of forehead then your friend is not so good in lying.
Of course, Richard Wiseman could just be lying about the whole thing…
