Lie Detector Affiliation Introduction A lie detector is a device used in order to determine the truth or falsehood of what one says. It uses a questioning procedure and other technology that records an individual’s physiological functions in order to detect whether their response is genuine or not. A polygraph is a device that concurrently records variations in physiological functions such as blood pressure, heartbeat, electrical resistance, and respiration. Due to technology developments, this system has grown both in its use as well in efficiency. However, one question begs as to how accurate and reliable the gadget is (Nahari, Vrij &Fisher, 2014).
Reasons for its growth
The demand for the lying detector has increased with many law enforcers adopting it in order to solve cases (Blumenthal, 2008).
Investors have contributed a lot by their need to see the system work more efficiently than ever, hence, more advancements contributed towards it
Aside from traditional methods of detecting the genuineness of one’s implications, there exists no other method of detecting lies; therefore, it is the only technology that can be used (Blumenthal, 2008).
Effects of lie detector
Positive effects include:
The largest percentage of the polygraph tests carried out produce accurate results, hence it is accurate
It is also reliable, as it enables the authorities to determine one’s authenticity of their response (Carlucci, Compo & Zimmerman, 2013).
It has enabled governments to rule out some primitive methods they used while trying to determine the truth in one’s confession (Carlucci, Compo & Zimmerman, 2013).
Negative effects include:
The system is not always accurate and, therefore, can cause a ruling to be fair or unfair based on the results (Moor & Carle, 1988).
There is also too much dependency on the system, whereby, the law enforcers completely rely on it rather than using other means of solving issues (Reinhard & Schwarz, 2012).
The society, at large, has adopted it and is using it in personal purposes like detecting family lies among others or by employers (Fischman, 1985).
In conclusion, lie detectors are good as much as they are bad. Its efficiency is both sided and the consequences can be lethal. It is, therefore, important, if there would be a way of improving its efficiency to 100 percent. This is mainly due to the fact that the basis the system use for detecting lies (blood pressure, sweat etc) can as well be as a result of other reasons like anger, and stress among others. Therefore, the system is not entirely accurate or efficient.
