The Hellinga Retractions (part 1): when replication fails, what should happen next?

Because Abi asked me to, I’m going to discuss the fascinating case of the Hellinga retractions. Since this is another case where there is a lot to talk about, I’m going to take it in two parts. In the first part, working from the Chemical & Engineering News article by Celia Henry Arnaud (May 5, 2008) [1], I’ll focus on the common scientific activity of trying to build on a piece of published work. What happens when the real results seem not to fit with the published results? What should happen?

In part 2, drawing from the Nature news feature by Erika Check Hayden (May 15, 2008) [2], I’ll consider this case in the context of scientific collaborations — both within research groups and between research groups. In light of the differentials in experience and power (especially between graduate students and principal investigators), who is making the crucial scientific decisions, and on the basis of what information?
But let’s start with the papers [3,4] that came out of the research group of Homme W. Hellinga, professor of biochemistry at Duke University.

Science and belief.

Given that in my last post I identified myself as playing for Team Science, this seems to be as good a time as any to note that not everyone on the team agrees about every little thing. Indeed, there are some big disagreements — but I don’t think these undermine our shared commitment to scientific methodology as a really good way of understanding our world.
I’m jumping into the fray of one of the big disagreements with this repost of an essay I wrote for the dear departed WAAGNFNP blog.
There’s a rumor afoot that serious scientists must abandon what, in the common parlance, is referred to as “faith”, that “rational” habits of mind and “magical thinking” cannot coexist in the same skull without leading to a violent collision.
We are not talking about worries that one cannot sensibly reconcile one’s activities in a science which relies on isotopic dating of fossils with one’s belief, based on a literal reading of one’s sacred texts, that the world and everything on it is orders of magnitude younger than isotopic dating would lead us to conclude. We are talking about the view that any intellectually honest scientist who is not an atheist is living a lie.
I have no interest in convincing anyone to abandon his or her atheism. However, I would like to make the case that there is not a forced choice between being an intellectually honest scientist and being a person of faith.

How committed are paleontologists to objectivity (in questions of ethical conduct)?

There’s another development in Aetogate, which you’ll recall saw paleontologists William Parker, Jerzy Dzik, and Jeff Martz alleging that Spencer Lucas and his colleagues at the New Mexico Museum of Natural History and Science (NMMNHS) were making use of their work or fossil resources without giving them proper credit. Since I last posted on the situation, NMMNHS decided to convene an ethics panel to consider the allegations. This ought to be good news, right?
It probably depends on what one means by “consider”.

Are imaginary friends a prima facie disqualification for a judge?

Via Ed Cone I found one of those stories that makes me love the Wall Street Journal: “In the Philippines, Ex-Judge Consults Three Wee Friends”:

As a trial-court judge, Florentino V. Floro Jr. acknowledged that he regularly sought the counsel of three elves only he could see. The Supreme Court deemed him unfit to serve and fired him last year. …
Helping him, he says, are his three invisible companions. “Angel” is the neutral force, he says. “Armand” is a benign influence. “Luis,” whom Mr. Floro describes as the “king of kings,” is an avenger.

Oh my.

Studying the ubiquitous (a puzzle about experimental design).

One of the strengths of science is its systematic approach to getting reliable information about the world by comparing outcomes of experiments where one parameter is varied while the others are held constant. This experimental approach comes satisfyingly close to letting us compare different ways the world could be — at least on many occasions.
There are some questions, though, where good experimental design requires more cunning.
