They care about effectiveness in the sense of if you asked if they cared about effectiveness they'd say yes. They don't care about effectiveness in the sense that they are doing the math on how effective different outreach is, comparing that against other uses of the money, and sharing that with their donors. I've been to 9-10 charity events and none of them talked about effectiveness in a dollar and cents way like the way givewell does. It's a real change from the status quo.
