Modern animal welfare science has shifted from focusing only on preventing suffering to also promoting positive experiences and flourishing.
The evolution from Five Freedoms to Five Domains represents a philosophical shift in animal welfare science. The original Five Freedoms focused on preventing negative states — hunger, pain, fear. The Five Domains adds a positive dimension: animals should not merely be free from suffering but should have opportunities to thrive. This shift asks not just whether animals are surviving but whether they are flourishing. Measuring and improving positive welfare outcomes is the frontier of applied animal welfare science.
