Some people asked about where the inference in the previous post came from. The two most recent instances I’ve encountered were in conversation with another student and in the comments on another student’s blog. I’m not sure where (whether?) I’ve seen it in an article or book. However, I have asked my roommate, another grad student, who says he has encountered similar ideas before; it sounded like it was in conversation with other people. I will be tickled pink if I find something like it mentioned in print. If that happens I will straight away put up a citation.
