We are lazy beings. When we find a pattern that suits us, we make a convention and stick to it. It becomes our law, our religion. Anything is wither within or without. And we judge.
Personally, I strive for 100%, I believe in n=1, and if a method is not described it does not mean the results are negligible. I believe inventions are just good observations, and plagiarism of the portion of the universe that we are able to perceive is the only chance we have to be creative.
