For several decades, one of the primary goals of those who run American newsrooms has been (and justifiably so, from my point of view) increasing the number of mainstream journalists who are African-American, Latino, Asian, Native Americans and part of other minority groups, defined by race.

At the same time, there have been less publicized debates -- mostly behind the scenes -- about the need to bring more intellectual and cultural diversity into our newsrooms. As one journalist friend of mine once put it, what's the use of bringing in more African-Americans, Latinos, etc., if they all basically went to the same schools as everyone else and have the same set of beliefs between their ears?

You can see these two issues collide in William McGowan's the much-debated 2003 book, "Coloring the News: How Political Correctness Has Corrupted American Journalism." He argues that years of diversity training in American newsrooms has actually made them more elitist and narrow, purging many professionals who come from blue-collar and non-urban backgrounds.

Before you write that theory off as conservative whining, what was that statement near the end of the famous New York Times self-study entitled "Preserving Our Readers' Trust (.pdf)"?

Our paper’s commitment to a diversity of gender, race and ethnicity is nonnegotiable. We should pursue the same diversity in other dimensions of life, and for the same reason -- to ensure that a broad range of viewpoints is at the table when we decide what to write about and how to present it.

The executive editor should assign this goal to everyone who has a hand in recruiting.

We should take pains to create a climate in which staff members feel free to propose or criticize coverage from vantage points that lie outside the perceived newsroom consensus (liberal/conservative, religious/secular, urban/suburban/rural, elitist/white collar/blue collar).
