First:polygraphs are unscientific.
Second:the woman just might be mentally ill and,as a result,truly believes that something that didn't happen did happen.(It can happen)
Third:it's my understanding that polygraphs can easily be "fooled" if the person being tested knows that they're in no danger.If this woman's lying she doesn't get money.End of story.
