Some people think that you should go all-in on particular giving opportunities. Some people think that you should diversify your giving portfolio. What assumptions and circumstances favor going all-in? What assumptions and circumstances favor diversification? And either way, what should your resources support?

Rethink Priorities’ Charitable Resource Allocation Frameworks and Tools Sequence (the CRAFT Sequence) addresses these questions via two tools: a risk-based portfolio builder, where the key uncertainties concern cost curves and decision theories, and a moral-parliament-based portfolio builder, which allows for the modeling of both normative and metanormative uncertainty. The Sequence’s primary goal is to take some first steps toward more principled and transparent ways of constructing giving portfolios. Our tools make debates about worldviews more tractable by illustrating how assumptions about cost curves, attitudes toward risk, and credences in moral theories can influence allocation decisions.
