The anchoring effect is very interesting. Unfortunately, Mcardle's article is riddled with inaccuracies. Please see the following post, which notes the many flaws in the article: http://scienceblogs.com/deltoid/2008/03/framing_iraqi_deaths.php

In other words, the Lancet study has not actually been discredited.

Dr X replies: Thanks for the link. My interest in the Mcardle piece was, indeed, the idea that anchoring effects bias our estimates. Although I didn't say so in the post, I was skeptical of Mcardle's position. She does seem, at times, to be on a mission to vindicate her support for the war. That should be, of course, a separate matter from any criticism of the Lancet study.

For the record, I do not feel especially confident that Mcardle is an objective critic of the Lancet study or that she is well-versed in research methodologies. It is interesting, nonetheless, to consider how anchoring effects might influence public perception of world events.
