Psychological claim: Polygraph Test is an Accurate Means of Detecting Lies.Research question: Is the polygraph test an accurate way of detecting lies? The objective of this research is to evaluate the use of scientific methods to verify the effectiveness of the use of polygraphs to detect lies as compared to the other methods. Critically, the polygraph test, known as the lie detector manipulates the individual’s physiological response to questions inquired by testing experts to determine whether they are saying the truth or lies. From the results recorded by the test machine, the machine can plot the physiological activities of the person, like the skin conductance, blood pressure as well as respiration on a continuous chart (Honts, & Reavy, 2015).

Nevertheless, there is much difference among individuals across the levels of physiological activity. For instance, an honest examinee may mistakenly prove to be deceptive when they sweat a lot during the test. Likewise, examinees that sweat very little may be mistakenly taken as truthful. Most part of this research can be categorized as theoretical. As such, the field does not require much research on various variables and mechanisms related when examining what is scientifically valid in psychology research, scientists must take into account many factors. In order to confirm the validity of psychological findings, experiments are required to confirm consistent, repeatable results.

The necessary components in an experiment include theories, hypotheses, and exact procedures so the experiment can be replicated. While researching a theory or hypothesis, psychological researchers need to consider the “pragmatic usefulness of an idea” (Shermer, 2011, para. 6). Astrology continues to fall into the realm of pseudoscience. According to Shermer (2011), astrology could not be considered a science because there is no “research that produces useful knowledge reflected in presentations, publications, and especially new lines of inquiry and research” (Shermer, 2011, para. 7).
