Science says that the temperature of our nose increases when we lie – known as the Pinocchio effect!
Remember the very famous Pinocchio whose nose grew with every lie he said? That tale that scared us as kids that we would meet the same fate if we lied to our parents about anything! Well, that is partially true.
The nose knows when you are lying! But you can breathe a sigh of relief as the noes doesn’t really grow but it does grow warmer, according to a study conducted by researchers at the University of Granada’s Department Of Experimental Psychology. These researchers, Gomez Milan and Elvira Salazar Lopez are pioneers in the application of thermography to the field of psychology.
The orbital muscle that is placed in the inner corner of the eye increases in temperature, along with the temperature near the nose. This is known as the ‘Pinocchio effect’. This is because when we lie, a brain element called ‘insula’ is activated – it is only activated when we experience real feelings.
Not only lying, anxiety attacks, sexual desires and other emotional responses bring about temperature changes in different parts of the human body – the effects being same in men and women.
The researches have use the technique of thermal imaging which is popular in various fields in life. This research which was first published around 2012, can find applications in the field of investigation, helping during interrogations, some what similar to the polygraph test! However, it would need further research and experimentation.
P.S. : Don’t go on playing detective and touch people’s noses when they answer a question you want to know the answer to. There might be other reasons for increase in the nose’s temperature and there are other conclusive methods like reading the body language to ascertain whether the person is lying.
