He asserts there is "little scientific testing, refinement and changing budgets to reinforce demonstrated success.
There is renewed emphasis on continuing applications of the 3Rs – replacement (of animals with alternative methods), reduction (in the numbers of animals used to achieve scientific objectives) and refinement (in experimental design, techniques and husbandry to minimise adverse effects and improve welfare).
In 1959, Russell and Burch published The Principles of Humane Experimental Technique in which they stated that all animal experiments should incorporate, as far as possible, the 3Rs: replacement (of animals with alternative methods), reduction (in the numbers of animals used to achieve scientific objectives) and refinement (of methods to minimise animal suffering) (Russell and Burch, 1959).
At one time it was believed that errors of measurement could eventually be eliminated through the refinement of scientific principles and equipment.
Others have made it clear that their structural realism is a purely epistemological refinement of scientific realism.
Results for test soils and standard reference materials (SRMs) suggest that concerted use of in vivo and in vitro methods combined with physicochemical characterization of soils provides a stronger scientific basis for the refinement of risk assessments for As-contaminated soils.
Models are scientific hypotheses subject to confirmation, refinement and refutation.
With AIDS, investigators soon recognized that injection-drug users, hemophiliacs and other demographic groups were also at risk, and the case definition evolved over time to incorporate lab evidence of immune dysfunction and other refinements based on scientific advances.
Therefore, the ARRIVE guidelines are a useful refinement tool, but the scientific community has to foster refinement and reduction on its own.
According to this Regulation, it is mandatory to perform a 90-day rodent feeding study for single transformation events, whereas "the Commission shall monitor the application of this Regulation, the developments in scientific knowledge on replacement, reduction and refinement of animal use in scientific procedures and the publication of new guidance from EFSA.
