The Columbia Journalism Review has more about Stephen Moore’s fact-challenged attempt to demonstrate the virtues of tax cuts, which I wrote about the other day. We learn a bit more about the story — the piece was published because Moore demanded the opportunity to reply to my column about Kansas — which makes it even funnier and more remarkable that he couldn’t be bothered to get the numbers right. Also, my favorite line from the piece:

The original version published in Investor’s Business Daily remains uncorrected as of this writing. (IBD, which identifies Moore as part of its “brain trust,” did not respond to a request for comment.)

There’s more: Moore evidently did not admit error gracefully, instead engaging in a “snippy” exchange in which he protested a column highlighting his errors. And when he did sort of correct what he wrote, he did so not by presenting data over the period he originally claimed to be covering, but by shifting from five-year comparisons to comparisons of job growth since 1990, which (surprise!) do show higher growth in low-tax states.

What strikes me here, again, is the laziness and sloppiness. State job numbers aren’t hard to look up, but apparently that was too much work. Beyond that, it’s obvious that Moore simply doesn’t expect anyone ever to check his facts.

For what it’s worth, I know that there are lots of people gunning for me, and I also work for a publication that takes corrections very seriously — they have to appear in print, in a subsequent column, as well as being appended to the original online. So I supply fact-checking material with every article; these days most of that material is at the links you can see in the online version.

Let me also say that the people who published the piece appear to have been extremely naive. Again, from CJR:

Of course, both Pepper and Brownlee were republishing a piece that had appeared elsewhere first—it was in IBD before the Star—and therefore should have been factchecked already. “You assume Heritage has edited these pieces too,” Pepper says. “But, lesson learned. There will be no future Heritage pieces published that don’t get thorough factchecking.”

Heritage, factchecking? That is really, really funny.
