There are lots of mathematicians, and statisticians and the like, who become interested in literary analysis. They may even go on to publish articles and books with their findings, applying mathematical or computational techniques to the study of literature. The problem is, they're usually only interested in their own insights, and shy away from the existing conversation that surrounds a given work of literature. These researchers seem to be unaware that literary scholars have been thinking about their same problems for years. Their bibliographies often contain hardly a single work of literary criticism. You wouldn't try to write a book about physics, or mathematics, without consulting a physicist or a mathematician, but somehow these scholars think that you can write a book about literature without being in dialogue with literary scholarship.
