“Maximising expected choiceworthiness involves diversification because the cost-effectiveness of each intervention decreases with spending. Going “all in” on the option with the highest marginal cost-effectiveness would only make sense for a very limited budget”
I’d argue almost all decision makers in the EA space operate in the linear regime where cost effectiveness does not meaningfully decrease.
Hi Simon. In that case, how do you explain that impact-focussed grantmakers support many interventions, even within a single area (see, for example, the Animal Welfare Fund)? If the cost-effectiveness of each did not meaningfully decrease with spending, one would expect them to focus on much fewer grants?
