To add, I also have issues with ACE's methodology & transparency. I don't have a background in stats or anything, but when I tried to independently verify ACE's evaluation of charity efficacy, I found several figures that seem (to me) not well-sourced. e.g., the 'source' column is mostly empty for ACE's AWO spreadsheet: https://docs.google.com/spreadsheets/d/1CAcmf4dXPk9tNWit25C7A7GJqEGNtnN-unXKZoyzvx4/edit
Compare with GiveWell's analysis: https://www.givewell.org/international/technical/programs/seasonal-malaria-chemoprevention#Sources
I'm still allocating my donations based on ACE's recommendations, but I'm really worried about how effective I'm being.
Yes, this!
