Types of Questions a Polygraph Examiner Will Ask

During a polygraph examination, the examiner will ask various questions to determine if the person is telling the truth or lying. These questions fall into three categories: relevant, irrelevant, and control.

Relevant questions are directly related to the issue being investigated. For example, in a criminal investigation, relevant questions may focus on whether the suspect committed the crime or has any knowledge about it.

Irrelevant questions are unrelated to the issue but help establish a baseline response for each individual. These questions aim to determine how someone responds when they tell the truth versus when they lie.

Control questions involve asking about behaviors that most people would have likely engaged in at some point. For example, “Have you ever lied to get out of trouble?” This type of question helps establish an individual’s physiological response when lying because many people may feel guilty or nervous answering such personal and potentially embarrassing inquiries.

Understanding what types of questions a polygraph examiner will ask can help prepare individuals for their examination and ensure accurate results are obtained.
