What if, instead of Astrology, we had pseudo scientific personality matrices based on more "hard math" principles?
"What your favourite platonic solid says about you?"
"I'm a cosine, he's a cotangent - how can we make it work?"
"Never trust a 19! The top 5 primes under 100 to avoid!"
Well first I'm gonna need the coefficient to the 2nd order integral of your ideal hyperbola ; p
Yeah, it comes up in some manga/anime, as well as a few Japanese developed video games. Of note, I believe the original Resident Evil made special mention of the major characters' blood types for that reason.
