There is a related statement in the field of software engineering, and specifically in open source software, which is another highly collaborative area (and an area where I have some experience in). It's called Linus's Law: which is the assertion that "given enough eyeballs, all bugs are shallow".
It means the same thing. Given enough people collaborating on a project, all errors ("software bugs" in the case of open source software) become shallow. In other words, "you eliminate a lot of the dumb errors".
This seems to be a general principle of collaboration.
I would be interested in knowing more about this newspaper article and when it was published.
