A native English speaking writer will only be as good as the materials he uses for research when writing the paper.
That's equally true for both ENL and ESL writers. That makes it what mathematicians refer to as a
constant; and it should be treated exactly the way mathematicians treat constants.
If the ENL is a fantastic researcher, then he will turn in a good, if not impressive paper, that will benefit the person who hired him.
Negative. Being a good researcher has nothing to do with whether or not someone happens (also) to be a good writer. Likewise, both being a good researcher
and being a good writer (in any language) have little to do with one another and nothing to do with how well someone writes in English if English isn't his native language. Is it possible for someone to become a good writer (in English) despite learning English as a second language? Definitely: both my father and my 10th-Grade English teacher were perfect examples. Do the vast majority of ESL writers write in English as well as ENL writers? Definitely not.
If his research is bad, then the paper will also be bad and not help the client.
This is true. However, this is also a
constant, precisely because it is equally true of both ESL and ENL writers. Aside from being a constant, research skills and English writing skills have nothing to do with one another: someone could be a great researcher and a horrible writer and
vice-versa, because those two skills are almost completely unrelated.
The better writing doesn't come only from the writer's ability to write in fluent English. It also comes from his ability to analyze and explain topics and evidence in written form.
Again, the ability to analyze issues and express ideas well in writing is another
constant, and one that differs tremendously among different people, even
within any given language, and that ability exists and varies irrespective of the language. If someone's writing is obviously ESL, it doesn't do an American or British or Australian client much good that the underlying research and/or strength of substantive argument might be good. There's no shortage of legitimate peer-reviewed journals published on other continents that illustrate the proposition that there are plenty of great researchers whose English writing is either bad or obviously recognizable as ESL writing (despite perhaps being pretty good otherwise). Writing well in English that doesn't exhibit any of the obvious indicators of (even pretty good) ESL writing is totally unrelated to how good or bad a researcher a writer might be.
The better writing doesn't come only from the writer's ability to write in fluent English. It also comes from his ability to analyze and explain topics and evidence in written form.
Both skills are critical, but (again), they're unrelated. Each of those skills is something that lawyers and logicians would refer to as "necessary but insufficient conditions" for the quality of work in this this industry, at least as pertains to ENL clients. Neither skill is worth much without the other.
What I am saying is that any writer, ENL or otherwise, given the same materials, and with equal English writing abilities, should be able to produce a usable paper for the student.@ Cite
Nobody would disagree with that. However, that's the crux of the issue: If ESL and ENL writers all had "equal English writing abilities," this wouldn't be a topic worth discussing at all. The issue is, precisely, that the vast majority of ESL writers do not exhibit "English writing abilities" that are anywhere even remotely close to being "equal" to ENL writers, leaving aside any and all
other issues and constants that ordinarily dictate the quality of academic writing.
