The lie detector is used not only for interviewing criminals and witnesses. When a person arranges for serious work, connected with a certain level of secrecy and requiring compliance with internal security rules, he is satisfied with a polygraph test. What is the principle of the device, and is it really showing the right information?
What is a polygraph
A lie detector is a device that captures the change of several physiological parameters at a time when the subject is asked different questions. How to pass a polygraph well? You need to know that the technical tool registers the pulse rate, respiration, blood pressure, electrocutaneous activity. A modern device is a mobile personal computer equipped with sensors and sensor blocks. In the course of the research, polygrams are written, which are deciphered by a polygraph specialist.
Polygraph offers to pass some participants of the crime and witnesses. The expert makes his conclusion on the results of the polygram, but it is not an irrefutable proof of guilt. The second branch of the lie detector application is a survey of candidates for certain positions in private business, in closed structures( police, Interior Ministry, FSB and other special services).So experts learn about the moral and psychological qualities of the applicant and conduct routine checks. For the auditee, this procedure is free, and the client-customer pays a rather high price for testing.
How is the testing on the
polygraph? On average, testing takes about 2 hours, but in some cases the procedure takes more time - up to 4 hours. The passage of the polygraph lasts longer if the subject is experiencing inadequate reactions, or it becomes necessary to ask a few more leading questions to add up the whole picture. Before you learn how to pass a polygraph, you need to familiarize yourself with the steps of the procedure:
- Preparatory. Includes data collection on a potential or current employee.
- Pre-test conversation. The person must explain the purpose of the check, list his rights. The specialist should indicate that the procedure is voluntary, ask about the state of health of the candidate. This allows you to further adjust the results or move the test to another time. The polygraph examiner refines the data collected at the previous stage.
- Test on polygraph. The researcher is asked a number of questions, combined into blocks. The specialist applies in practice one of the existing techniques developed for different cases.
- Finishing. The person is offered to say something on the merits of the check, if there is such a need. When physiological responses differ from the norm, the applicant is asked to explain the reasons for this.
What questions are asked when hiring a job
Those who are for the first time to go through a lie detector, there are certain unrest. Polygraph when employed is used today more often than before( especially in Moscow and other large cities), so it's worth being mentally prepared for the testing procedure. At the same time, the employer does not violate the law. What questions are asked on the polygraph in this case? Tests are divided into three types: actual, tuning, corrective. The questions can be answered "yes" or "no".
How to successfully pass a polygraph? Be prepared for the fact that on-line( when you are connected to the device) you will be asked about theft, use of drugs, alcohol, smoking, game addiction. Often the topic of conversation is the availability of loans and arrears, criminal history, relatives with a criminal record. You will need to give an answer if you have any malicious intentions towards the company.
Is it possible to fool a polygraph

The less you see the difference in reactions when answering usual and especially tricky questions, the more useful it is for you. Counteraction to this device is possible. How to deceive the lie detector is known to pathological liars, professional actors and social psychopaths( because they do not always adequately perceive social norms).However, a simple person can pass the test under the force.
