I really think I've gotten this far in my academic career simply by knowing how to craft good sentences, not by having good ideas. But maybe those are more related than I give myself credit for.
Anyway, here comes Mohan and Lo 1985: "We suggest that if there are differences in the ability of Chinese and Western students to organize essays in English, the source of these differences does not lie in a preference for “indirectness” in the language and culture of Chinese. Rather, it lies in the emphasis of the English language instruction programs to which students are exposed."
That's what I'm sayin', bro.
