:::: Murray is referring to [http://www.conservapedia.com/Mystery:Young_Hollywood_Breast_Cancer_Victims this poorly researched thesis proposed by ASchlafly], Able806. No data to support the thesis was ever provided by ASchlafly. I'd invite you to take a look. [[User:StatsFan|StatsFan]] 12:40, 20 June 2008 (EDT)

::: Looking at the paper, it seems to me almost all the experimental data is shown in figure 1: the ability of the bacteria to utilize citrate as revealed by optical density measurements. Something clearly happened around generation 33000, and the OD measurements jumped fivefold (from 0.05 to 0.25) with the range of measurements over three samples being way, way less that 0.2 (the size of the jump). That seems to be it experimentally. The rest of the paper describes the methodology and discusses what could have caused the change.
::: People keep talking about raw data. Would someone who says that explain what they mean? To me, raw data is relevant when what is reported is derived data. For example, suppose you have a study of health effects of working at a facility that handles nuclear material. You report the radiation exposure over background of workers. That is derived data. The raw data are the workers' dosimeter readings and the background radiation measurements. That is what you would ask for when you wanted the raw data which supported the derived data.
::: But in the Lenski paper, as far as I can tell, the data reported is the actual measured data: they measured the optical density of the samples and reported those numbers in figure 1. Of course, I could be wrong, I am not an expert in this field, but if someone disagrees with me, please tell me what the raw data would be and how the data in figure 1 was derived from it. (Lenski said that all the data being asked for is in paper. That statement is consistent with what I am saying.)
::: As to 14 days, I do not see any problem. This is a very exciting result to people in the field and the reviewers would very likely put it on top of their to do lists. As I say, the experimental data is simple and unambiguous (something significant happened at generation 33000), the description of the methodology is clear and straightforward, and the discussion of the causes is at least consistent and believable. What is there to object to?
::: Aschlafly talks of 'concealed data'. Could you please tell me what data you believe is being concealed? Specifically, what measurements are not revealed? (I know you can say 'how could I know if they do not tell me', but can someone at least suggest what kind of information is not being revealed?) -divaricatum 10:03 June 20 2008 (PDT)
