At the ISAHP 2009 meeting in Pittsburgh, Thomas L. Saaty offered a challenge to the attendees to explain the eigenvector solution of the pairwise comparison judgment matrix that is the basis of the Analytic Hierarchy Process so that it would be understandable to any intelligent layman. He wrote an essay himself on it during the meeting, and submitted it as his offering. A second essay on the subject, also during the meeting, was written by Stan Lipovetsky. These two papers appear in this issue of the journal.
