[Question] What is the right number of EA-aligned donation advisors?

November 2023 update:

Sjir Hoeijmakers and colleagues at Giving What We Can have addressed this question very nicely in two posts: Overview of effective giving organisations and GWWC’s evaluations of evaluators.

Original post:

We’ve got

And probably others (not to mention groups like Rethink Priorities, OpenPhil, The Effective Altruism Foundation, and Good Ventures who fund these projects but also play a somewhat overlapping role).

  • Is this too many? Too few?

  • Has there been a side-by-side comparison to establish overlaps and differences between them?

  • Has there been meta-evaluator work to establish which of the evaluators/​advisors qualifies as an effective charity?

I did some cursory research this morning and didn’t find anything so I figured I’d ask. Apologies if I overlooked something obvious.

Thanks in advance,
