Take the example of the Caine myth in Vampire, which is literally described as one of the possible explanations for the Kindred condition, but has become incontrovertible fact in the game world, even to the point of having systems support it (Generation).

Specific instances turn into universal standards and become ossified, often to the game's detriment.
It's why i think the Anarchs fail, like "anarchs can be anything, from a baron to republic to a cult" while only really showing how to run barons will lead STs to only running barons and all.
The problem here isn't that players latched into one example, it's that WW didn't invest in developing diverse examples.
