The emerging science of positive welfare measurement provides tools for assessing whether animals are experiencing genuinely good lives, not merely the absence of suffering.
Positive welfare science represents a paradigm shift that elevates the aspiration of animal welfare from minimizing harm to enabling flourishing. This shift matters because it changes what we look for when evaluating welfare quality, what we design when building enrichment programs, and what we demand when advocating for welfare standards. A welfare assessment that only asks "is this animal suffering?" misses the question "is this animal thriving?" — and animals who are not obviously suffering may still be living impoverished, restricted, unstimulating lives that do not constitute genuine welfare. The science that measures good lives, not just the absence of bad ones, enables a higher standard for what we accept as adequate welfare.
