Pinocchio Effect

What if liars were easily noticeable? What if they had to wear something certain or act a specific way if they were living with a lie? Or what if they had a distinct feature to themselves like Pinocchio did? The world would truly be a better place. Everyone could spot a liar. And the liars would be ashamed because they are known. Liars would be put on the spot. Everyone would want to know why they lied and what they lied about. The exposure of liars could possibly create a stereotype suggesting that certain groups of people lie. If the exposure of being a liar is cruel towards someone and they feel ashamed and betrayed, maybe that feeling would influence them to lie less or even not lie at all. By having the ability to recognize a liar, people could know that someone is lying the second that it happens. Exposing liars could be a hazardous thing but could also be very beneficial to society.
