The animal advocacy movement has increasingly adopted rigorous effectiveness analysis to identify which interventions produce the most welfare improvement per dollar and activist effort invested.
The application of impact analysis to animal advocacy has produced important insights about where effort and resources produce the most welfare improvement. The finding that corporate campaigns securing welfare commitments from food companies affect welfare practices for millions of animals simultaneously has directed significant advocacy effort toward this high-leverage approach. At the same time, honest uncertainty about which advocacy strategies are most effective in different contexts argues for portfolio investment across multiple approaches. The movement has benefited from a culture of evidence-seeking and willingness to update strategy based on outcomes that is relatively unusual in advocacy contexts.
