Identify and solve problems in experimental designs.

Among these methodological problems are biases that lead to the overestimation of the effect under study and underestimation of experimental noise, poor research protocols and study design, and inappropriate use and interpretation of statistics.

Update: Six French scientific academies issued a statement on 19 October, saying the Séralini study could not reverse previous conclusions that this and other GM crops are safe, because of problems with the experimental design, statistical analysis and animals used, and inadequate data.

«We solved multiple problems simultaneously by changing out the electrode, improving the electrolyte and creating good contact and communication between the two materials,» said Haile, who led the development of the concept, guided the experimental design, and supervised the research.

ACE thinks that some of HLL's early studies were not conducted as well as they could have been, and that there were problems in some of the write - ups of those studies.262 For example, HLL conducted five studies with the same participant pool, which might have caused the results of some of those studies to be influenced by earlier experimental manipulations.263 Some studies also did not include appropriate control groups, and many studies did not control for desirability bias.264 We think these early studies helped influence animal advocates to see research into animal advocacy methods as possible and desirable, but that their utility is otherwise limited by some of their design flaws.

Every good science «debate» have ever seen took an hour or so to mull over a tiny question, led immediately to a couple new testable hypotheses and experimental designs — each of which required a few months of independent bench work, though in some fields a week of computer time might be a more appropriate tool — and then ended up in a second, reconvened session in which evidence was presented and another aspect of the problem was discussed.

I did so, and in so doing pointed out a number of problems in the M&N paper (comparing the ensemble mean of the GCM simulations with a single realisation from the real world, and ignoring the fact that the single GCM realisations showed very similar levels of «contamination», misunderstandings of the relationships between model versions, continued use of a flawed experimental design etc.).
