THE POLYGRAPH INSTITUTE
One of the professional departments in Gil Investigations is the polygraph lab.
The polygraph is an old device which has been converted to work through a computer, as part of the global computerization process.
The polygraph investigations are conducted in our company by Yohai Kitron, who was once head of a polygraph lab in the Israel Security Agency. The polygraph inspector's professional level is a sure indicator of the test's success. The device is an inchoate object operated by an inspector, whose skills can be shown in absolute results.
When our company co-operates with other leading companies, the use of polygraph is very developed and the test is conducted in two phases:
Phase A – Preparing the tested person and familiarizing him with the polygraph device in order to lower his sensitivity and tension threshold.
Phase B – Connecting the tested person to the device and conducting a demonstration of banal questions such as name and address, while sharing the results with the tested individual.
After the completion of the preliminary test, the list of questions is asked. It should be stated that the number of questions has to be limited, and they should be accurately worded.
Every tested person must be tested in his mother tongue, in order to prevent errors. We guarantee results which are parallel with the truth.
