guilty knowledge test

The guilty knowledge test is a forensic method used to determine whether someone has specific knowledge related to a crime. It works by presenting the person with multiple choices, including the correct details only the perpetrator would know. If the person responds in a way that indicates familiarity with the real details—such as showing recognition or physiological responses—the test suggests they may be involved. This approach relies on distinguishing responses to known versus unfamiliar information, making it useful for identifying guilty parties when direct evidence is limited.
