Rigorously evaluating the welfare impact of interventions is essential for directing resources to approaches that genuinely improve animal lives.
Welfare impact evaluation is a scientific and methodological challenge that the movement has not fully met. Without rigorous evaluation, resources may flow to interventions that feel impactful but have modest welfare effects while genuinely effective approaches remain underfunded. Building evaluation into welfare intervention design from the start creates the evidence base needed for strategic resource allocation and continuous improvement.
