I feel this in the realm of larp game design
In New England, we have all reached these conclusions about how to run a game. These conclusions were developed through 15-20 years of mistakes. There is this shared model of "how larps work" and people get real defensive about it.
Every so often a newcomer steps onto the stage and has some crazy new idea.
The veterans go "No, that will never work, we tried it, it sucked"
but you know...
sometimes it actually does work
There's something about the newcomer mindset, the person who lifts up a rock with no expectation of what they'll see.
There's something about "Outsider Art" - art not inspired by the artistic tradition, but coming from some novice whose never taken Art History. It's often clumsy and naieve and makes predictable mistakes, but also, it seems like the only way to escape the paradigm.
You can never enter the same river twice, and hail eris for that.
