Potential Animal Welfare intervention: encourage the ASPCA and others to scale up their FAW budget

I’ve only recently come to appreciate how large the budgets are for the ASPCA, Humane World (formerly HSUS), and similar large, broad-based animal charities. At a quick (LLM) scan of their public filings, they appear to have a combined annual budget of ~$1Bn, most of which is focused on companion animals.

Interestingly, both the ASPCA and Humane World explicitly mention factory farming as one of their areas of concern. Yet, based on available data, it looks like <5% of spending in this category is directed toward factory-farmed animal welfare — despite factory farming accounting for the overwhelming majority of total animal suffering.

Given that factory farming is already in scope for these orgs, and that is responsible for the vast majority of animal suffering, it would seem quite reasonable for these orgs to increase their spending on FAW several-fold. I doubt their donors would object!

Should GiveWell offer Animal Welfare regrants on an opt-in basis?

The GiveWell FAQ (quoted below) suggests that GiveWell focuses exclusively on human-directed interventions primarily for reasons of specialization—i.e., avoiding duplication of work already done by Coefficient Giving and others—rather than due to a principled objection to recommending animal-focused charities. If GiveWell is willing to recommend these organizations when asked, why not reduce the friction a bit?

A major part of GiveWell’s appeal has been its role as an “index fund for charities.” While ACE and similar groups offer something comparable for animal causes, GiveWell has a much larger donor base, and donors often prefer to consolidate their giving into a single recurring contribution. An optional Animal Welfare allocation could serve those donors better while remaining consistent with GiveWell’s stated reasoning.

Why doesn't GiveWell recommend organizations focused on animal suffering?
GiveWell has not prioritized research into organizations focused on animal suffering in part because there are two organizations we know well that are investigating this question: Open Philanthropy and Animal Charity Evaluators. We have limited research capacity, and would guess that we may come to similar conclusions as those groups about which groups to recommend, although we would likely have a different research process[...]We generally point interested individuals to these two organizations when they reach out to us for recommendations in this cause area.
