The lie detector is a really interesting device, with the help of which specialists have been able to repeatedly reveal these or other frauds or crimes. However, the modern type of lie detector does not already include a polygraph, as before, but a functional MRI machine, which makes device deception even more difficult - but not in the opinion of researchers from the University of Plymouth in the USA. Today, a team of researchers presented their test results, during which she tried to deceive the modern type of lie detector - and not without some success in this regard. As it turned out, the main role here is played by two interesting techniques of deception.
The operation of a functional magnetic resonance tomogram is based on the analysis of the condition and blood flow to those brain areas that are responsible for trying to hide the release of information about the question or object being asked - on this basis, researchers may indicate that a person is most likely lying about the question asked . However, as for the two new techniques of deception of a lie detector, they generally relate to deception of the so-called “superficial judgment”, in which a person interrogated on a lie detector can concentrate on something completely foreign, as suggested by the first deception technique , or on something superficial, but related to the subject matter, as evidenced by the second technique of deception.
Thus, even if a person gives out a certain part of truthful information about the question being asked, he can still hide a lot of details, replacing one object with another in his thinking - although this requires some cognitive practice, scientists say that in this way deceive the detector lies are even possible.
This was confirmed by their own research into checking a lie detector with the help of both techniques - however, they still note the fact that it is most likely to withstand both techniques if the functionality of an MRI machine inside almost any modern lie detector is enhanced.
