When is an animal model unethical as well as invalid?
If an animal model cannot deliver the knowledge that is supposed to justify the harm, using it fails scientifically and morally — 3Rs are not enough.

What they did
The authors link the harm–benefit justification of animal research to validity. They take activity-based anorexia (ABA) as the leading rodent model of anorexia nervosa, show it models a symptom (excessive exercise under food restriction) rather than the whole disorder, and name a standardisation–translation paradox. They urge reversed translation from the clinic and treat ethics as more than harm reduction.
What they found
Invalid models are uninformative and morally unjustified. Uncertainty is especially high in neuropsychiatry. ABA is not a model of AN as a whole. Ethics cannot be reduced to the 3Rs; research quality benefits from ethical reflection.
The limits
What it doesn't show
This is not a new ABA experiment and does not quantify how often ABA findings fail in humans. EU 2010 is cited as legal background, not analysed as a full statute.
Key terms
- 3Rs
- Replacement, reduction, refinement — standard harm-minimisation principles in animal research.
- ABA
- Activity-based anorexia: restricted feeding plus running-wheel access producing excessive exercise and weight loss.
- Standardisation–translation paradox
- Tight experimental control can make a model less like messy patients, hurting translation.
- Reversed translation
- Start from a clinical question, then design the animal experiment.

Common questions
Why is validity an ethical issue?
Harm is justified only by knowledge; an invalid model does not deliver that knowledge.
Is ABA ‘the’ AN model?
It is often called the most promising, but it captures a symptom, not the whole disorder.
Are the 3Rs enough?
Necessary but not sufficient, on this argument.
