How many questions are asked of someone during a polygraph examination?
Typically an polygraph examiner can cover three (3) specific issue questions during a single examination, as long as these questions are related to one another (see above). These three specific issue questions will take approx. 90 to 180 minutes to cover effectively due to the extensive polygraph examination process required. If more questions must be asked, another polygraph examination must be designed and conducted following the first one. This usually adds to the time and cost involved. Finally, a healthy individual can only produce readable polygraph charts for a limited period of time. After this time has expired, it is impossible to generate a conclusive polygraph examination and any further examinations must be scheduled for a different day.
