We often see polygraph test being used on people in order to get to the truth of something. But how accurate are polygraph tests? We see polygraph tests on some of our favorite television shows; from Law and Order Special Victims Unit to Dr. Phil, etc. but how accurate can they be? Polygraph tests have always been something I was skeptical about because how accurate can a lie detector test be since sometimes our body can give a different answer. With that being said, can one really go off from a polygraph exam to determine the fate of a person? The polygraph test is conducted by using a polygraph machine. Polygraph exams can exhibit false results, in those scenarios, how can one determine these exams to be accurate? We assume that when we use polygraph tests we will …show more content…

How can one determine these exams to be accurate in truth-telling? The scientific method is there to help you follow/guide you to conduct a successful research study. The scientific method is used in many professional fields including chemistry, physics, biology and psychology. Landrum (2017) mentions how psychologists traditionally use the scientific method for use in research articles that can range from laboratory results, student research papers and formal manuscripts submitted for publication to peer-reviewed journals. Everyday psychologists, chemist, biologists, and other professionals use the scientific method to guide us through the research being conducted. In this case, I would use the scientific method to help guide me in running a successful research study to help determine the accuracy of a polygraph exam when knowing the exam can exhibit false results. Professionals would make observations, gather information, form theories, test predictions and interpret results all which is the standardized way of the scientific

  • The Effect Of Negative Body Talk On An Diverse Sample Of College Students

    739 Words  | 2 Pages

    The scientific method is how psychologists gain knowledge about the mind and behavior. It is used by all scientists. The experimental method is the one way to engage the scientific method, and the only way to find a cause and effect in relationships. It is summarized in five steps, observing some phenomenon in the world, forming a hypothesis which is an educated prediction about relationships between two or more variables, examining the gathered information by using empirical research, determining what the results are and drawing them, and evaluating the results whether it will support the hypothesis or not. Researchers, at the end, submit their work for publication for all to see and read (King, 2016). There are three types of psychological research in the scientific method, descriptive research, correlation, and experimental research (King, 2016). The article The Effects of Negative Body Talk in an Ethnically Diverse Sample of College Students (Katrevich, Register, & Aruguete, 2014) is an example of the experimental method.

The polygraph was first used in 1895 and later on modified to modern technology and computerize around 1992. Polygraph has been around for centuries but is still an inconsistent technique and grounds for errors at court. The polygraph can cause the case in court to be grounds for dismissal and well as a mistrial.

  • Forensic Evidence Essay

    1204 Words  | 3 Pages

    Whereas the real picture of forensic evidence is unlike what is represented in movies and television shows where a fingerprint or a trace of hair is found, then it’s game over for the criminal. Reality is not as straightforward. As more people are exposed to the unreal forensic world through television and media the likeliness for a wrong conviction increases with juries assuming the evidence involves more science than what it really does, this is known as the CSI Effect. Further education and training is needed for the people of the court, the forensic specialists, and so called experts. The people in courts do not question any of the ‘professionals’ and just trust in their expertise. The court could overcome this perception by requiring explanation of error rates in a forensic field. To do this, testing examiner error rates will be necessary which means further research. Forensic science has such a large effect on the prosecution of suspects, experts have been known to provide questionable and at times incorrect evidence. When a false conviction occurs the true perpetrator is set free. Once realized, the public doubts the justice system and the reliability of the forensic evidence even more. At this point in time, forensic is an inexact

    Psychology is the scientific study of the mind, brain, and behavior. In psychology, and all of the other sciences, relying on opinions is abandoned in order to find out which explanations best fit the evidence or data given. Science continually forces us to question our findings and conclusions. Over time, psychology has advanced greatly and a main reason for such progressiveness is because of the change in the research model used.

  • Reliability of Polygraph Testing

    1315 Words  | 3 Pages

    A popular way on many crime dramas to determine if a suspect is lying or telling the truth is by hooking them up to a polygraph machine. In a matter of a minute the police are able to determine if the suspect is lying and guilty or, on the rare occasion, telling the truth and innocent. But, one has to wonder, is it really that simple? Polygraphs measure four main factors that are thought to change when a lie is told and more importantly, it is assumed that these changes indicate deception. The four main factors are blood pressure, heart beat, perspiration, and breathing and these are recorded by using simple devices. It is important to note from the beginning that those who question the reliability of polygraphs do not doubt the reliability of the measurements, but the ability of the measurements to indicate and/or prove deception. Even though doubt exists as to the reliability, polygraphs are used not only in law enforcement settings, but also in intelligence agencies, in the maintaining security of industry, and for public safety and service around the world. Despite its prevalence, there are many groups that call into question the effectiveness, reliability, and fairness of polygraph testing. This paper will explore this question by first looking into the history of polygraphs including court rulings and how polygraph tests are done, then current use, and finally looking at sources of bias and error in the test and the process.
