Polygraph testing is used by people who want greater clarity about a specific event when conversations, documents, or other available information have not resolved the issue. In the UK, private lie detector tests may be considered in relationship disputes, workplace investigations, theft allegations, business conflicts, and other situations where one clearly defined factual question needs to be examined.<\/p>\n
A professional polygraph test is much more structured than the dramatic \u201clie detector\u201d scenes often shown on television. The examiner does not simply connect a person to a machine and decide whether every answer is true or false. A large part of the process takes place before the recording begins, including a detailed interview, discussion of the issue, and careful preparation of the questions.<\/p>\n
