What are the three phases of polygraph examination?

A polygraph examination consists of three distinct phases: 1) Pre-Test Phase (Information Collection); 2) In-Test Phase / Polygraph Examination (Chart Collection);

What are the objectives of a polygraph examination?

The primary purpose of the polygraph test in security screening is to identify individuals who present serious threats to national security. To put this in the language of diagnostic testing, the goal is to reduce to a minimum the number of false negative cases (serious security risks who pass the diagnostic screen).

Can a normal person able to beat the polygraph result?

Defeating a polygraph against novice students is possible, but defeating an experienced examiner is harder. According to Goodson, some people who are telling the truth can fail polygraph tests by trying too hard to control their body’s responses.

Are polygraphs 100 accurate?

Typically, when someone is lying, a well-trained polygraph examiner can tell. It is not 100% accurate though. They estimate the accuracy of the polygraph to be 87%. That is, in 87 out of 100 cases, the polygraph can accurately determine if someone is lying or telling the truth.
