Err if you think that quote debunks the study you've just claimed to debunk the entire area of opinion polling.
Exactly.
article said:
This stunning toll was more than 10 times the number of deaths estimated by the Iraqi or U.S. governments, or by any human-rights group.
That's not unusual for warzones. [eta: I'm assuming that, by Human rights group, they mean Iraq Body Count -- who have not conducted a survey, they just read news reports]
Under-reporting of deaths happens in warzones. The more violent the warzone, the bigger the discrepancy. Surveys give more accurate figures. That has been the experience of past warzones.

a memo by the MoD's Chief Scientific Adviser, Sir Roy Anderson, on 13 October, states: "The study design is robust and employs methods that are regarded as close to "best practice" in this area, given the difficulties of data collection and verification in the present circumstances in Iraq."
Les Roberts, one of the co-authors, has conducted many surveys. He says deaths are often under-counted in war-zones, and by a large degree.
He also gives a method whereby his data can be easily refuted. Lancet-2 recorded 547 post-war deaths, about 300 of them violent. (Amongst 12,801 people in the survey). So more than half died a violent death.
What percentage of people die in the categories of old age, sickness, accident or violence? If the violent deaths don't account for quite a few, then Lancet-2 is wrong. Isn't it about time we had a few jounalists visit a few morgues? Last time I checked, I couldn't find such data.

Before the war this morgue located at Bab al-Mu'atham near the city centre received only about 200 to 300 bodies a month, Dr Kais Hassan who has worked at the morgue said.
[...] "Most of those brought dead here have been tortured by beating, electricity, acid, drills, and by other horrible ways," said an Iraqi who refused to give his name. "When any Iraqi is arrested by police now it means we will find his dead body in Baghdad's streets after some days. Because of all this killing, this morgue is not enough."
[...] "A week earlier they brought more than 100 bodies in one day from al-Taji north of Baghdad, and another day they brought just 20 bodies. There is an average of 50 to 60 bodies everyday."
But that morgue might specialise in violent deaths, so the proportion given may not be meaningful. And other morgues may have closed, so the numbers given might not indicate an increase in death rates. But I can't find jounalism on morgues in Iraq that give the answers needed.
Here's the old thread from the science forum,
