The primary purpose of polygraph testing in security clearance is to identify individuals who pose a serious threat to national security. To put it in diagnostic test language, the goal is to minimize the number of cases of false negative results (serious safety hazards that pass the diagnostic test).
What are the benefits of a lie detector test?
A lie detector test can help find out the truth in many situations. They are incredibly helpful and accurate, with an average success rate of 90% or more. The test is painless and both affordable and accessible. Read on for some cases where a test like this can be used.
What does the lie detector really detect?

How accurate is the lie detector test?
There have been several reviews of the accuracy of lie detectors. They suggest that polygraphs are accurate between 80% and 90% of the time. This means that polygraphs are far from foolproof, but they are better than the average person’s ability to spot lies, which research shows is possible about 55% of the time.

How many times can polygraph results detect lies?

What are the pros and cons of the lie detector test?
