Title: The Polygraph
Thesis: To inform my audience about polygraphs, the polygraph tests, and the controversy of them.
Introduction
I. Attention Getter: For more than 15 years, Robert Hanssen had led a double life. In one life he was a 25-year veteran with the FBI who had access to some of the nation’s most-classified information. In his other life, he was a spy for the Russian government. Hannssen’s deception was finally discovered, and in February 2001 he was arrested, and then took a polygraph test which forced him to plead guilty to 15 espionage-related charges.
II. Thesis Statement: Today, I am here to talk to you about Polygraphs, the polygraph tests, and the controversy of them.
III. Credibility: My brother-in-law had to take a polygraph test for his job. And he was forced to prepare for it a year in advance, ever since I saw his preparation for this one test; I have forever been fascinated by this invention
IV. Preview: First of all I will give you a bit of background information on polygraphs, and then I will talk about the actual test you take. Finally, I will discuss the controversy behind a polygraph test.
(Transition: How did the Polygraph test come about?)

I. Background information
A. John A. Larson, a medical student at the University of California, was the inventor of the polygraph.
B. John invented this machine based on the theory that when a person tells a lie, he/she will have a fear of bein...
One of the last types of ways investigators are coached to detect deception is in the behavioral attitudes of a person being interviewed such as being unconcerned or over anxious (Kassin, 2005). The success rate of looking for these cues are very successful in telling if an individual is being deceitful and has surpassed any laboratory tests conducted on the subject. The laboratory test however did reveal some interesting facts. The research showed that people who had training and experience did not score better than the control group who received no training. In fact all individuals scored at the chance level with the people who had training scored just above chance or at the chance level. To check if special training in the detection of deception was more accurate a study ...
“Why College is Still Worth It Even Though It Cost Too Much.” Money.com (2015): N.PAG. MasterFILE Complete. Web. 11 Oct. 2016 The author of this paper address that a lot of college students feel like the time, money, and effort is not worth it; However, studies show that it does pay off by receiving higher pay, better work hours, and better benefits, such as insurance plans. A poll was done using college alumni to see if they thought that college paid off, and of the 30,000 that were in the poll a majority of them agreed that it did. Also, the writer includes several other polls conducted to show the life-long impacts of a college education, which includes better career and friendship
Leonhardt believes it is a smart decision to go to college because it increases the amount of money a person will earn if they earn a college degree. However, Matthews is discouraging readers that college is not really a smart decision because of the loans they have to make up. He also argues that college graduates don’t make more money than a high school graduate. Getting a college degree is important for teenagers and adults in order to have a greater success, more money he or she will earn, and most importatntly, more knowledge he or she will
In my opinion, Chris Matthews did not present a compelling argument. Addressing the possibility is not enough at all to convince someone at any time to either think that going to college or not is a good choice. Telling someone that 25% of people who get their bachelor degrees will get paid less than the median of a high school graduates is not convincing at all. It’s like saying that teens who are 16-19 years old should not be driving at all since 60 percent of deaths among passenger vehicle occupants ages 16-19 were drivers,According to the Insurance Institute for Highway Safety in
Could someone trust the results of a lie detector test? It is not hard to control the responses that someone is looking for. It is hard to distinguish between nerves from the test or nerves from lying. Many people can respond differently to lying, there is no set reaction to deception. Can we really trust the results of a lie detector test, or is it something we have created to be able to put the blame on someone. Lie detector tests do not determine truthful statements.
In both cultures honesty and trustworthiness is important when giving expert witness accounts especially when under oath in courts or tribunals. It is important that one not make false or misleading statements. It is important to take reasonable steps to insure that the information being presented is correct and pertinent information is not intentionally left out. (Annals of Family Medicine.
So, are you interested in buying a new car, or at least a new used car? Well don’t let the problems of car buying deter you. Although buying a car can be an intricate and tedious process, there are certain guidelines even professional car buyers follow. With a few points of information on how to find the right car, the tedious car-buying process can be made easy.
Employment and interpretations of the polygraph poses as the greatest threat to the testing subject. It is generally agreed upon psychophysiologist's that there is no specific lie response. Basically, no specific action has been identified and allocated as an irrepressible deceptive cue. This seems to be very contradicting to the whole purpose of the polygraph test. The fact that the polygraph is wide open to interpretation crates invalidity from the start.
The polygraph is a very controversial topic when comes to the introduction of the techniques into court. The polygraph technique has not changed since first developed in 1895. What the polygraph does is measures the blood pressure fluctuation, pulse rate and respiratory rate changes. The rate of the blood pressure, pulse and respiratory rate not only changes due to the body being stressed because the person is lying, but it also changes due to anxiety, anger and medical conditions. This will affect the accuracy on the technique and give inconsistent readings within the results (Gailus, C., 2008, November

In today’s society, the idea of receiving a college education has been pondered quite a bit as to whether or not it is actually worth it. According to Michelle Adam, many people “…today believe that getting a good education is key to success in our society, this revealed surprising issues that challenge the notion of higher education being worth its price tag” (59). Naturally, many high school graduates apply for college right before or after graduation. Others decide to go into the work force, armed forces, or simply remain unemployed. The question that many people debate about is, is a college education worth it in the long run? Though some people believe a college education will benefit ones’ career, others believe it will cause a mass of debt and loans for college students and graduates, and postpone life events.
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.
Researching the Hierarchy of needs pyramid this is was done because he wanted to understand what motivates people. What was believed was that people take a set of motivation system unrelated to rewards and unconscious desires. Maslow stated that people are motivated to achieve certain needs. When one need is met a person seeks to fulfill the next one and so on. http://www.simplypsychology.org, 2007-2014 . With the Maslow hierarchy of needs it starts at the bottom and work its way up to the top. One must fulfill lower lever basic needs before
There are a lot of decisions being made when looking for a vehicle. In order to make the right ones you have to understand what you want but mainly what you can afford. There are many ways you can purchase a car, whether you buy it from a car dealership or a private seller, the process is normally the same. The first thing you should do is set a budget that suits your needs. This will save you from having financial problems later. You don't want to receive repossession letters months ahead for not paying your car on time. Next you want to decide on whether you prefer a new or used vehicle. Pre-owned vehicles require more attention because unlike new vehicles, they've had...
(Baran, 2016) Polygraphs don’t actually measure lies, they measure the differences between how truthful suspected criminals react to relevant questions. (Sterbenz, 2015) Polygraphs are only considered from scientific and legal committees. (Baran, 2016) The Polygraph test is not trulley accurate, and suspected criminals can cheat on the test. To get a lie detector off course, suspected criminals will do indiscriminate things. For example, When a polygraph tester asks a question such as, “have you ever lied in your life?” The suspected criminal will answer truthfully. But to get the polygraph tester off course, the suspected criminal will thrust their foot down on a thumbtack. (Wolchover, 2011) When a suspected criminal assaults their foot down on a thumbtack, this motives the suspected criminal to sweat, and causes the suspected criminal’s blood pressure to accelerate. (Wolchover, 2011) The suspected criminals sweat and change in blood pressure will cause the needles to rise. (Wolchover, 2011) Now, a questions graph the suspected criminal told the truth about; looks the same as a questions graph they lied about. (Wolchover, 2011) To pass a polygraph test suspected criminals make sure they stay calm, maintain their breathing, answer questions without hesitation, make sure they do not think about the topic too much, and answer with yes or no, making sure they don’t do much explaining. (Wolchover,
