It often obscures more than it clarifies, and ought to be avoided
In a letter urging US News & World Report to alter the formula it uses to rank law schools, The State Bar of California offers this argument:
There is a broad consensus among law school deans and professors that diversity greatly enhances the educational experiences of law students. Exposure to and an understanding of diversity better prepares students to practice in an increasingly diverse setting and to respond to the needs of the global economy, making it even more important that diversity be included as a factor in the rankings.
Set aside your stance on this issue. Is anyone else put off by the excerpted argument's slipperiness?
It's as if the author is trying hide something. Were the word "diversity" struck from the paragraph, he would be forced think hard about his precise claims and how to back them up. (Try a re-write yourself.) As drafted, however, he can't even commit to a single meaning for the word: it shape-shifts several times in the space of two sentences. A bit farther along, we're told that "among the challenges we face as a nation is the impact of our increasingly diverse population."
What does that even mean?
