Pity the Rich Genius

I’m not quite sure how one quantifies it, but Crain’s Chicago Business has decided that writers given half-million-dollar MacArthur “genius” grants become fat, slovenly pigs. Actually, the publication has found a correlation between getting one of these awards and a significant decline in the quality and quantity of an author’s output. There’s even a handy, authoritative chart! Is there a cause-and-effect relationship here, or is the MacArthur Foundation simply an excellent judge of when writers are past their primes? (Via Salon.)
