Should you encourage a rape victim to take a polygraph?

• A. No. please don't
• B. Yes, go ahead
• C. Sometimes, if the victim agrees
• D. It depends on jurisdiction

Answer: (A)

The main idea here is that you should not pressure a rape victim to take a polygraph. In practice, the focus with trauma survivors is on voluntary, trauma-informed support and investigation, not on using tools that can cause additional harm. Polygraphs measure physiological responses that can be influenced by fear, anxiety, pain, medications, and the stress of recounting a traumatic incident, not simply truthfulness. Their reliability is limited, and in many jurisdictions they are not admissible as evidence in court. Because a polygraph can be misleading and its results can unfairly influence a victim’s sense of legitimacy or culpability, encouraging a victim to undergo one can retraumatize them and undermine trust in the investigative process. Therefore, the best approach is to avoid encouraging the victim to take a polygraph and instead offer supportive resources, explain that participation is voluntary, and let the victim decide based on what is most comfortable for them. The investigation should prioritize documenting the survivor’s account, safety, and access to services, while using evidence collection and interviewing methods that are respectful and trauma-informed.
