Several countermeasures designed to pass polygraph tests have been described. Asked how he passed the polygraph test, Aldrich Ames explained that he sought advice from his Soviet handler and received the simple instruction to: "Get a good night's sleep, and rest, and go into the test rested and relaxed. Be nice to the polygraph examiner, develop a rapport, and be cooperative and try to maintain your calm".  Additionally, Ames explained, "There's no special magic....Confidence is what does it. Confidence and a friendly relationship with the examiner...rapport, where you smile and you make him think that you like him".
