The choices between putting a roof over a family in The Philippines and saving a child from malaria in Myanmar is an impossible one. Information can't solve it.
I have nothing against Give Well's approach. I think it is important. I'm just making the point that at a personal choice level, the "problem" is a lot more solvable. You only need to know about one charity, really.
It's possible that I don't understand your response, because I don't see why one only needs to know about one charity. On reflection, I don't think that it is an impossible problem either. It's making uncomfortable tradeoffs - which stopped me from considering this sort of question for a long time - but I've come to believe that these questions are too important to flinch away from.
One thought experiment to consider: suppose the homeless family themselves had to choose between a free wooden house or lifesaving medical care for their child. What would most families choose? What would you choose in their place? Is there a right answer?
