Without criteria for pooling experiments into a meta-analysis, the court docket simply cannot identify whether the exclusion of scientific tests prone to disprove EPA's a priori speculation was coincidence or intentional. Second, EPA's excluding virtually 50 % from the obtainable experiments directly conflicts with EPA's purported reason for analyzing the epidemiological experiments and conflicts with EPA's Possibility Evaluation Tips.
