Government jobs and other security jobs require that you take a Comparison question test (QCTs) since there is so much deception that could happen in those settings. The researchers had five different research questions that they wanted to look at when it came to QCTs. Number one was based around there being differences in the scores when it came to physiological reactions between a probable or directed-lie. The second was looking at if repeating the questions affected the scores between probably or directed-lies. Third, would there be differences in the scores if a computer used an algorithm to come up with the scores versus a human doing the scores? Fourth, do the probable-lie CQT show less spontaneous scores than the directed-lie CQT? Lastly, if you added a certain measure, would this change the results in the accuracy of scoring. The measure the researchers were looking at we called peripheral vasomotor reaction (PVR).

            The researchers put an ad on Craigslist to find their participants. They had many restrictions that they had to take in consideration that led to having to get rid of a lot of choices. The total number of participants was 250. They would then be split up into groups. One group would watch a video showing that they were the innocent group meaning that they did not steal $20. The second group was the guilty group who did steal the $20. The examiners would bring each participant in and ask then 11 questions is which they had to answer with a yes or no. After the answers were recorded they would go do a comparison test in which the only thing that was different was the order of which the questions were asked. After everything was done, it was asked of the participants to answer some questions of what they thought about the research study and were later told their results.

            The results were all over the board with all of the different things that were being tested. It was hard to keep track. Some weren’t significant at all while others were very significant in different directions of the scores.

            In conclusion, it was noted that when the polygraph test is given in a lab setting that it leads to mock crime trials that are not valid and do not help when it comes to comparing it to real life events because it wouldn’t be accurate. The test is also said to not have a good chance at predicting field validity based on finding deception in a lab setting. There needs to be more research on this because the more researchers can find out about the polygraph test, the better chance it will stop being used incorrectly in any situation.
