There is a scene in the movie ‘Right Ya Wrong’ where the lie detection test is conducted on Sunny Deol, who played a role of firebrand police officer. The test is conducted because his colleague (Irfan Khan) feels, Sunny has murdered his own wife and her boy friend. Sunny passes the test. Can anybody passes lie test as it is shown in the movie? According to Dr Nilesh Anand Bharne, Additional Commissioner of Police (Crime), who did PhD on the subject related to lie detection tests, it is not possible. “A hardcore criminal, if prepares himself, may succeed to some extent.
There are several minor things. When question is asked while conducting the test, the body gives responses. There is galvanic skin response, one sweats. Actually, it is in his/her subconscience mind so it is very difficult on their part to hide. If one has achieved meditation of high state then the person can deceive the techniques,” said Dr Bharne. The study submitted by Dr Bharne is ‘To validate Forensic Assessment interview with polygraphy technique in identifying deception/truthfulness in crime cases’. He was awarded Doctor of Philosophy by Raksha Shakti University.
The study was done under Faculty of Forensics and Behavioural Sciences. His guides were Dr Shivarathna Lalit Vaya and Dr Asha Srivastava of Institute of Research and Development, Raksha Shakti University. Dr Vaya is Director, Institute of Behavioural Sciences, Gujarat Forensic Science University. His study revealed interesting conclusions. For example: The number of percentage speaking truth is more in women while men are more deceptive, they tell lie. Secondly, the percentage of telling lie is more in economically weaker section. If one goes further deep, mostly the males in the age group of 18 years to 30 years tell lie. Dr Nilesh Bharne is the first person in India and probably in the world to have studied assessment of lie detection techniques.
What prompted Dr Bharne to choose this critical and complicated subject? A student of Psychology, he did MA, MPhil in Psychology, and also cleared NET, SET. All these lie detection tests like NARCO, FAINT, Polygraph, brain-mapping and co-relation of their results was studied by Dr Bharne. They give results to the approximation of 90 to 99%. FAINT- Forensic Investigative Interview tells accurate 86% of times, polygraph has accuracy of 98%, brain mapping is 99%. “We get confused which is to be done. Whichever technique you use it gives valid result. I got result and drawn their correlation. Their philosophy, fundamental everything I studied. All techniques are inter-correlating.
They are giving truthful and valid results. It is a psychology and we deal with humans. There are so many combinations. We can’t get 100% result. These tests can’t match DNA, blood group,” Dr Bharne made it clear. Dr Bharne did not do just for the sake. It took him 6 years. He collected 100 samples each of men and women involved in three types of crimes -- Murder, Sexual assault and Theft. Finding time out of his busy schedule, Dr Bharne, a firebrand police officer, studies socio-economic aspects also. He divided samples in lower, medium and higher. “Lower are more deceptive.
They don’t have social pressure, environment is bad, no education, poor background. About females, they have home pressure, they are more God-fearing so they speak truth. Males have more chances to lie, they are dominated. Every criminals have different questionnaire. I have made two age groups--18 to 30 and 30 to 60. Age group-wise also 18 to 30 are more deceptive while above 30 are truthful. Dr Bharne said, “Since there is lot of pressure and we have to follow guidelines of National Human Rights Commission (NHRC), I think these tests have future. Secondly, there is one more test called ‘Layered Voice Analysis’ has come. If a person tells lie while speaking he would tremble and the test would detect the same.”
