In some ways, I think Matt is giving Tom Friedman too much credit when he says that, "in order to reach a pox on both houses conclusion [Friedman] finds himself ignoring the very strong similarity between auctioned permit plans and carbon tax plans." I wouldn't, in this case, chalk up to ideology what I can attribute to incompetence. Instead, I'd bet that Friedman simply doesn't understand that auctioned permit plans are essentially equivalent to carbon tax plans.
This could've been caught, of course. Any expert would have noticed the misunderstanding at the heart of Friedman's argument. But no expert saw the piece before publication. So far as structural problems go in journalism, the way we do fact checking is actually a big one. Friedman's column probably went to some mid-level fact checker at The New York Times, who looked on the web sites of the various candidates, marked down that they had nothing called a "carbon tax" in their plan, and put a big checkmark on the day's Tom Friedman column. Same with Kit Seelye's piece, which went to some intern, who checked her quote and the googleability of the facts, and okayed the article. For the sort of errors Seelye and Friedman are making to be caught, their copy would actually have to be evaluated by someone who understands the relevant policy issues. Anyone familiar with climate policy could have identified the problem with Friedman's argument, anyone with an interest in health policy, or basic statistics, could have seen the glaring methodological screw-up at the heart of Seelye's piece. But no such individuals were asked to weigh in on their pieces. Instead, the rough drafts went to the "fact checkers," who do something different and altogether less relevant.
