Effective altruism frameworks applied to animal welfare focus on identifying where intervention produces the greatest benefit per unit of resource. Scale, neglectedness and tractability analysis suggests some causes are far more impactful than others.
Applying rigorous cost-effectiveness analysis to animal welfare giving reveals striking differences between causes. Campaigns that shift institutional purchasing (restaurant chains, supermarkets, university dining) affect millions of animals per dollar spent; individual consumer outreach is often hundreds of times less efficient. Neglectedness analysis reveals that fish welfare and insect welfare are dramatically underfunded relative to the number of animals affected. Effective altruism frameworks push beyond intuitive giving toward rigorous impact assessment - sometimes producing counterintuitive conclusions that challenge default charitable preferences.
