We can only test FACTS that the Subject has a reasonable expectation of knowledge and recall. Maryland polygraphs and EyeDetect tests cannot test intangibles such as feelings, thoughts, fantasies, or future intentions. Lie detector tests can’t ask hypothetical questions or ask about how their actions could effect someone else’s feelings. It’s important to understand that most people don’t remember minor details such as every website they’ve been to, every person they’ve flirted with or every lie they’ve ever told. A polygraph or EyeDetect lie detector test in MD cannot clarify every minor detail but they can give you a solid “yes/no” or “true/false” answer to one large overall issue. All lie detector tests are limited on the amount of questions they can ask. Therefore, it’s very important to focus on the largest, most important issue only.
