Remember that the members of the writing department have little or no formal education. Their primary qualification for landing the job they have is how "spiritual" they are.
In JW-world, being "spiritual" is exactly, 100% equal to being "obedient".
When some poor schlub with a high-school education, but with an above-average natural talent for spelling or writing coherently, is plucked from the laundry or construction crew or whatnot, they are trained in the "Bethel way" of writing.
What is the "Bethel way"?
Regarding quotes: "Is the stuff between the quotation marks accurately transcribed? Read in isolation, does it support our preferred point? Then use it!"
Of course, anyone trained as a writer in a university, or heck, anyone who has a passing knowledge of ethics, would not do so.
But remember the point made above - "spiritual" = "obedient".
The newbie writing department schlub figures, "Hey, these guys [instructing me] have way more experience, and are far more spiritual than I am - if they say it is OK, it must be OK!"
And so he learns to do that, and does so for 10 or 15 years....then it is time for him to train another newbie schlub from dishwashing or housekeeping as a "writer". And the cycle continues.
