Reproducible studies are certainly better than nonreproducible, but this bill limits our ability to study the environmental impacts of one-time shocks, such as the impact of Hurricane Katrina on the erosion of the Louisiana coastline or the impact of the BP oil spill on fisheries or coastal tourism, which would be important data for Mississippi businesses. There are other statistical methods that can be used in these situations to explore causal links. Removing the flexibility of the EPA to conduct research is problematic and seems designed to eliminate their ability to conduct research while simultaneously seeming like you are promoting "better" research. If you want to stop the EPA from conducting research, then pass that bill and own your decisions. If not, the agency needs the flexibility to use nonreproducible causal methods to understand and interpret data.
