wo men, Robert and James, applied for an engineering position. Both applicants having the same qualifications were asked to take a test by the department manager.
       
       Upon completion of the exam both men only missed one of the questions. The manager went to Robert and said, "Thank you for your interest, but we've decided to give James the job."
       
       Robert replied, "Why? We both correctly answered nine questions. I believe I should get this job, especially since I've grown up in this town and James just moved here."
       
       The manager said, "We made our decision not on the correct answers, but on the question you missed."
       
       "How could one incorrect answer be better than the other?," asked Robert.
       
       "Simple," said the manager. "James put down on question #5, 'I don't know', and you put down, 'Neither do I.'"
