The shrimp welfare project
Efforts by effective altruists to reduce suffering in farmed shrimp—such as promoting electrical stunning before freezing—are provoking sharp reactions over how we value non-human life. Supporters argue that if shrimp are even minimally sentient, cheap interventions that prevent mass, intense pain could be among the most impactful uses of charity. Critics counter that the underlying “moral math” is speculative, anthropocentric suffering is not meaningfully quantifiable across species, and pushing such arguments risks both moral absurdity and further alienating people from the effective altruism movement.
Overall reactions
- Split between people who find the argument persuasive enough to donate and those who see it as absurd, satirical, or even dangerous.
- Some describe the piece as unsettling but thought‑provoking; others think it exemplifies what they dislike about Effective Altruism (EA) and “rationalist math.”
Moral tradeoffs: humans vs animals
- Many commenters insist they would always prioritize one human over any number of shrimp; some extend this to millions of animals vs one human.
- Others use edge cases (kittens, rabbits, pets, partners) to show how partiality and emotional attachment distort abstract “lives saved” reasoning.
- A minority explicitly argue that large amounts of animal suffering can, in principle, morally outweigh a single human’s suffering.
Can suffering be quantified and compared?
- Heavy debate over treating “suffering” as a scalar that can be added, compared, and expressed as percentages.
- Objections:
- Intensity vs duration vs number of individuals may not combine linearly.
- Functions could be non‑linear or bounded; there may be no number of headaches worse than torture.
- The “billion dust specks vs one tortured person” style thought experiments feel morally wrong even if mathematically tidy.
- Defenders argue that refusing to quantify just pushes people back to vague “vibes,” which is worse for decision‑making.
Do shrimp (and similar animals) suffer?
- Supporters point to work on nociception, behavioral avoidance of noxious stimuli, and welfare‑range estimates; emphasize uncertainty but argue even a small chance of intense shrimp pain justifies cheap harm reduction.
- Skeptics question:
- Whether “3% of human suffering” for shrimp is meaningful.
- Using lifespan or neuron counts as proxies.
- Whether arthropod nervous systems support anything like human‑style experience.
- A hard‑line minority deny that “suffering” is a coherent or measurable phenomenon at all, especially for non‑verbal animals.
Utilitarian / EA framing and backlash
- Some embrace shrimp welfare as a high‑leverage EA cause; others see it as grotesque “ghoulish math” that implicitly devalues human‑focused aid.
- Critics argue EA’s quantitative style is pseudo‑rigorous, built on stacked, weak estimates and “common sense” appeals.
- Several worry such arguments harm EA’s public image and widen the gap between elite rationalist ethics and ordinary moral intuitions.
Practical responses and alternatives
- Supportive commenters frame donations as marginal harm‑reduction given existing demand for shrimp, not an endorsement of eating them.
- Others argue the morally obvious answer is to stop eating shrimp (or most animals) rather than optimize killing procedures.
- Suggestions include:
- Lobbying for regulatory standards instead of just buying stunners.
- Funding alternative proteins and “low‑suffering” diets.
- Prioritizing larger animals with more calories per death if one insists on eating meat.
Meta: rationalism vs moral intuition
- One thread argues that many people reject this style of argument not because they are “irrational,” but because they don’t accept morality as a computable optimization problem.
- Tension highlighted between:
- Those who want to systematically extend empathy and utility calculations across species.
- Those who see such calculus as disrespecting deep, local, community‑based moral intuitions and leading to alienating conclusions (e.g., shrimp over humans).
