Lie Detector Test Results and Interpretation
When a polygraph test is administered, the results are not just a simple yes or no answer. Instead, the test yields a complex set of data that requires sophisticated interpretation techniques to arrive at a conclusion. In this section, we will delve into the methods used to interpret polygraph test results, including graphical and numerical analysis, and discuss the various scoring systems used to evaluate polygraph test outcomes.
Methods of Interpretation
Lie detector tests are designed to measure a range of physiological responses, including heart rate, blood pressure, skin conductance, and respiration rate. These responses are then analyzed using various techniques, including graphical and numerical analysis.
-
Graphical Analysis: This method involves creating a visual representation of the physiological responses measured during the test. A skilled interpreter will examine the graphical output to identify patterns or anomalies that may suggest deception. Graphical analysis can be particularly useful for detecting subtle changes in physiological responses.
-
Numerical Analysis: In this method, numerical values are assigned to each physiological response based on their magnitude and duration. These values are then evaluated to determine the likelihood of deception. Numerical analysis can provide a more objective measurement of physiological responses than graphical analysis.
Scoring Systems
Most lie detector tests employ a scoring system to evaluate the results and determine the likelihood of deception. These scoring systems may include the following:
-
Dots per Minute (d.p.m.): This is a popular scoring system used in polygraph testing. The d.p.m. score is calculated by comparing the number of times the test subject’s heart rate deviates from the baseline rate during the test. A higher d.p.m. score indicates a greater likelihood of deception.
-
Physiological Response Index (PRI): This scoring system measures the magnitude and duration of each physiological response during the test. A higher PRI score indicates a greater likelihood of deception.
Verifying and Corroborating Results
Once the lie detector test results have been interpreted and a conclusion has been reached, it is essential to verify and corroborate the findings with other forms of evidence. This may include:
-
Witness Statements: If other witnesses or individuals have information about the alleged infraction, their statements can be used to corroborate the results of the lie detector test.
-
Physical Evidence: Any physical evidence related to the alleged infraction, such as security footage or forensic evidence, can be used to corroborate the results of the lie detector test.
Remember that polygraph test results should never be taken as the sole evidence of guilt or innocence. A comprehensive investigation and corroboration of findings are crucial to arrive at an accurate conclusion.
