Matthew Jockers has analyzed a corpus of 19th century American and British novels (Macroanalysis 2013). Using standard techniques from natural language processing (NLP) Jockers created a 600-dimensional design space for a corpus of 3300 novels. There is no temporal information in that space, but when the novels are grouped according to close similarity that grouping generates a diagonal through the space that, upon inspection, is aligned with the direction of time. That implies that the process that created those novels is a directional one. Certain (kinds of) novels are necessarily earlier than others because that is how the causal mechanism (whatever they are) work. This result has implications for our understanding of cultural evolution in general and of the relationship between cultural evolution and biological evolution.
