Return of the dumb

Megan, Iraq, blargh.

1. The disparity between the Lancet figures and the new count is higher than people are assuming; the Lancet study is more than a year older than the NEJM one. Since the violence was trending upwards, if the new study is correct, the Lancet figures were wildly, wildly, wildly off.
2. The new version is more likely to be correct; it covers a longer time period, uses a bigger sample, and employs more than one method of counting.
3. It is not that likely to be correct, in the sense of giving us a good, descriptive number. Iraq is a war zone, and it is very hard to collect good data. Beware of false precision, particularly if it validates your priors.
4. One would obviously wish that the Iraqi government were not involved.
5. Attempting to salvage the Lancet study by distinguishing between violent and non-violent deaths are silly. Virtually all the violent deaths in the Lancet study were excess, and virtually all the excess deaths were violent.
6. 150,000 deaths is a figure that should make any supporter of the war swallow hard.
7. There are good reasons to conduct public debates about these sorts of things with courtesy and humility.
Let's reorder those points.

1. "150,000 deaths is a figure that should make any supporter of the war swallow hard."

2. There is no second fucking point. Reread the first, and realize that according to the original Washington Post article, the true estimate was a range of 103-223k.

3. "It is not that likely to be correct, in the sense of giving us a good, descriptive number. Iraq is a war zone, and it is very hard to collect good data. Beware of false precision, particularly if it validates your priors."

Unless we're talking about the Lancet study.

Precisely, it was an infuriating post. Like how in the hell is she a statistics expert, if she fails to acknowledge that we (the US) have never counted Iraqi dead, no matter who they were. We just don't count them. So she is celebrating a report that has a very conservative estimate. Big whoop.

Hey, Brad, check out dsquared's post at Crooked Timber if you haven't already. His comments to McArdle's post are good too.
