Our topic for Chattering Class this week: Psychology's infamous Rorschach test. And our teacher is author Damion Searls. His new book, "The Inkblots," is all about Hermann Rorschach, an artistically-inclined Swiss psychiatrist who in the 1910s learned he could diagnose patients just by asking them to describe what they saw in abstract blots on paper. He talks with Rico about Hermann's history and what made the Rorschach's blots so effective and unique.
