I'd like to think he actually read a book on it! Wild. The 42 Entertainment people, at least, went out of the way to include a lot of technical and scientific jargon in the Add Violence artwork, which indicates a slightly more nuanced understanding than the typical dorm-room lecture on YouTube (not throwing shade here, just saying TR is well-read and probably put lots of thought and research into the 'concept' before throwing it out at the last hurdle, which is very reminiscent of Bleedthrough).
