so in many cases there this thingy where people have found relationship between Fibonacci numbers and petals of various flowers... ok that seems to be countable and there exists similar occurrences in various fields however enneagram relies on something like there is enneagram and everything is supposed to be one type through something... maybe I should say discretization method [as traits are multidimensional and from quite unimaginable blob and in the end that is projected onto two dimensional plane with nice regularly placed points, I find this quite funny] that seems to be quite undocumented, lol. Not that socionics is hugely better...
