You might think you're a great judge of character, but despite that, when you are confronted with a practiced liar it is impossible to tell from looking at them, body language or eye movements, whether they or not they are telling the truth. Don't trust your instincts. Don’t take a chance. Trust Cincinnati Polygraph Associates: we offer a full range of lie detector testing services and we can administer them in our office or at your location (subject to suitable facilities being available).
