Thanks for saying what I’m sure a bunch of people were thinking! Strong disagree with this take :-), but I understand why you believe it!
First a point of clarification—I’m confident you think the 10% personal giving is less effective, but it’s not 100% clear to me which 45% of my giving budget you consider to be reduced in effectiveness… I assume you mean the high risk, high return bucket? That’s not how I view it; this is my budget for hits based giving, which in my view has very high expected value, comparable to the higher confidence, lower upside giving budget but with a different theory of change.
At core, I think one crux of our disagreement might be this: is it overall more impactful to optimize the expected value of individual donation decisions sequentially, or is it more impactful to optimize the expected value of all of your donation decisions collectively (i.e. your full portfolio).
I accept that giving opportunities are power-law distributed. But I’m relatively skeptical in my (anyones) ability to accurately assess where any one giving opportunity sits on that power-law distribution with high levels of precision beyond a certain threshold. I feel fairly confident I can identify and exclude bottom 50th percentile giving opportunities, but distinguishing between 75th and 95th percentile giving opportunities I’m less confident in.
That’s true even when discounting for uncertainty… in practice there are so many assumptions built into a robust cost-effectiveness estimate, that reasonable people can defensibly land in assessments that are several orders of magnitude different from each other. That doesn’t mean we shouldn’t try! But it does mean we should have high levels of humility in our conclusions.
I make the decision to optimize my portfolio as a whole (with diverse theories of change, diverse risk profiles, diverse world views), which I think makes the expected value of my portfolio higher than if I viewed every donation decision in an isolated manner. Simply because there’s less risk I put all my giving eggs in a basket that ended up being wrong because of a reasonable but minor assumption.
