In his final column for the New York Times, departing Public Editor Arthur S. Brisbane discussed a number of issues he saw with the paper, but the one that's getting the most attention suggests the paper as a whole is biased towards progressive causes:

I also noted two years ago that I had taken up the public editor duties believing “there is no conspiracy” and that The Times’s output was too vast and complex to be dictated by any Wizard of Oz-like individual or cabal. I still believe that, but also see that the hive on Eighth Avenue is powerfully shaped by a culture of like minds — a phenomenon, I believe, that is more easily recognized from without than from within.

When The Times covers a national presidential campaign, I have found that the lead editors and reporters are disciplined about enforcing fairness and balance, and usually succeed in doing so. Across the paper’s many departments, though, so many share a kind of political and cultural progressivism — for lack of a better term — that this worldview virtually bleeds through the fabric of The Times.

As a result, developments like the Occupy movement and gay marriage seem almost to erupt in The Times, overloved and undermanaged, more like causes than news subjects.

Jill Abramson, the editor of the paper, disagrees with this assessment. ”In our newsroom we are always conscious that the way we view an issue in New York is not necessarily the way it is viewed in the rest of the country or world. I disagree with Mr. Brisbane’s sweeping conclusions,” she told Politico.
