Idea
Good intentions leave a choice unresolved
Two programs can both help while producing very different benefits from the same budget. Choosing between them requires asking what would happen without the intervention, how strong the evidence is, and whether more funding would still produce additional benefit. A persuasive story about one beneficiary cannot answer all those questions.
Effective altruism extends this comparative approach to donations and other choices. Charity evaluation makes one application concrete: examine outcomes rather than treating low administrative spending or an appealing mission statement as sufficient proof. The comparison concerns consequences, not just the donor's sincerity.
A generous choice still has an alternative.
Compare the additional good your next contribution could make.
Where it breaks down
Numbers do not remove ethical disagreement. Different people may value outcomes differently, and easily measured benefits can crowd out important but uncertain ones. Estimated impact also does not excuse deception or other harmful means. A ranking is an argument with assumptions, not a moral permission slip.
How it connects
Opportunity cost explains why doing some good does not settle where to help.
This idea appeared in The comparison inside a good intention, the Involves connection for October 16, 2026, which asked: How should helping change when the same resources could help more elsewhere?

What can an impact estimate not settle by itself?
Every disagreement about values, evidence, and acceptable means. Exactly. Quantification informs judgment without replacing ethical reasoning.
What the sources establish
Comparative evaluation involves outcomes and alternatives rather than intention alone.
