However, we think there are some limitations to these measures, and give weight to other factors. I expect that GiveWell would find interventions that have benefits beyond subjective well-being more cost-effective than HLI would.
It’s not easy to respond to this—it’s not stated what the limitations and other factors are.
More generally, there’s no reason to think in the abstract that, if you’re pluralist rather than monist about value, this changes the relative cost-effectiveness ranking of different actions. You’d need to provide a specific argument about what the different values are, how each intervention relatively does on this, and how the units of value are commensurate.
For example, imagine a scenario where intervention X provides 15 units of happiness/$ but does nothing for autonomy and intervention Y provides 10 units of happiness/$ and 10 units of autonomy/$. If we take one unit of happiness as being as valuable as one unit of autonomy, then Y is better than X. However, someone who only valued happiness would think X is better.
