UCLA professor Mark Kleiman explains the danger to the Washington Post in standing by George Will's dishonest hackery:

when you, on behalf of what used to be a respected newspaper, endorse his dishonesty, there's something seriously, seriously wrong. There are still honest and competent reporters writing for the Post, but if any article in the paper is to be believed it will now have to be on the basis of the reporter's known integrity and skill, not on the fact of its publication in a newspaper that not only publishes palpable falsehood but then justifies doing so.

That's via Matthew Yglesias, who made a similar point yesterday:

This started as a problem for Will, his direct supervisors, and the Post's ombudsman. But now that the Post as a paper is standing behind Will's deceptions, I think it's a problem for all the other people who work at the Post. Some of those people do bad work, which is too bad. And some of those people do good work. And unfortunately, that's worse. It means that when good work appears in the Post it bolsters the reputation of the Post as an institution. And the Post, as an institution, has taken a stand that says it's okay to claim that up is down. It's okay to claim that day is night. It's okay to claim that hot is cold. It's okay to claim that a consensus existed when it didn't. It's okay to claim that George Will is a better source of authority on interpreting the ACRC's scientific research than is the ACRC. Everyone who works at the Post, has, I think, a serious problem.
