So, the post says that pop lyrics are getting stupider because the ratio of unique words to total words has went down, though both total words and unique words have gone up. I'm not very convinced. How do you know that the right metric isn't something like unique/sqrt(total)? Can we figure out the right metric from first principles?
No. The post says that this was Briggs' original claim. This post proceeds to "dig deeper" and concludes "I think it’s difficult to definitively call today’s music 'stupider'".
