Sets of Ethical Principles
Set Principles Citation
3Rs Replacement - with other species or non-animal methods Russell and Burch, 1959
Reduction - fewest animals necessary
Refinement - use the most refined approach



3Ss Good Science - reduce variation using effective techniques and fewest subjects Carol Newton (Smith and Hawkins, 2016)
Good Sense - the correct animal used for the correct reason (valid and translatable model)
Good Sensibilities - reduce likelihood of the animal experiencing “contingent suffering"



3Vs (Validities) Construct Validity - is the animal valid for the scientific objective? Eggel and Würbel, 2021; Würbel, 2017
Internal Validity - is the approach and protocol appropriately designed?
External Validity - will the work generalize to other animals or humans based on its purpose?



4Fs (Fundamental principles) 1. Biomedical research principle - statement on the need for biomedical research Tannenbaum, 2017
2. Animal research principle - statement on the requirement for the animal research
3. Medical research with human subjects - statement on the limitations of human research
4. Animal research aims - minimize pain or distress to the animals



6Ps (Principles) Principle 1 - no alternative method Beauchamp and DeGrazia, 2019
Principle 2 - expected net benefit
Principle 3 - sufficient value to justify harm
Principle 4 - no unnecessary harm
