Do lie detectors have a future?
The aim of this paper is to present the analysis of lie detectors in the future that whether there is a future of lie detectors or not.
According to the science fiction novel which was published in the year 1996, a device was invented by scientists in it detecting lies with accuracy and perfection. The aim of this detector was to remove crime, changing the world and save generally humanity to get destroyed by itself. If our current technology is seen then the machine can never be a reality. The presences of polygraph for over a century along with wire offenders as well as needles which are twitching become an essence of investigating crime. But the evidence is not solid that all the signs which is looks into such as heart rates being fast, breaths being shallow as well as skin which is moist are actually evidences which are indicating towards a lie being told. The lie detection device unlikely has got any better and the theory pinned under it is fluffy as well as the evidence base being lacking and weak as there is no proper evidence towards any thought mentioned and any result which has been depicted (Hakun 2009).
The future from this perspective, is being understood by various scientists and from various approaches. The polygraph being abandoned the thought process towards designing the future of lie detectors has turned towards brain scanners. The field has been dominated by two technologies. The first one is that in which sensors which are electronic are used measuring the signal which is electrical in nature and other one is called the brain wave also known as the P300 appearing when something has been recognized. When this signal is looked for, it can be told potentially that whether knowledge is hidden over something that has been familiarized like a weapon for murder. The creates usefulness but is a way which is still far from being called as the method of lie detection which is complete with all the purposes as well as all the field figures. There have been consistent arguments about how effective the method can be throughout various years (Rowell 2002).
Another way is the fMRI or the functional magnetic resonance imaging known affectively as the blobology because of the pictures with various colors produced by it. The location is shown for neuron firing in a manner which is indirect tracking the flow of blood supplying nutrients along with oxygen in a suffice manner. There are various studies showing fMRI as...
