Versed vs. Unversed
When I decide to read a non-fiction work on a certain subject, I always look at the author's biographical information. Overall, I could care less about the small blurbs about their personal lives. No, when researching a particular subject and seeking literature on the matter, I care about pedigree. Where did they go to school? What did they study? What authority do they have to speak on the matter-at-hand? All these questions become vitally important, as I don't wish to waste my time or be misinformed or worse, misled. (For example, if I desire knowledge about the role of the United States in international relations, I am much more likely to consult Colin Powell as Ann Coulter.)
