Descriptors of an auditor

I just finished Freakonomics. It was an easy read and interesting. It would be a good text for a beginning class on auditing. At the end of the book is some "bonus material." Included is the original NY times article about Steven Levitt written by Stephen Dubner, the co-authors of Freakonmics. Mr. Dubner describes Mr. Levitt as a detective, an intuitionist, and an accidental provocateur. I think these are also descriptors of performance auditors.
