These values that we included in the CCM for these interventions should probably be treated as approximate and only accurate to roughly an order of magnitude. These actual numbers may be a bit dated and probably don’t fully reflect current thinking about the marginal value of GHD interventions. I’ll talk with the team about whether they should be updated, but note that this wasn’t a deliberate re-evaluation of past work.
That said, it important to keep in mind that there are disagreements about what different kinds of effects are worth, such as Open Philanthropy’s reassessment of cash transfers (to which both they and GiveWell pin their effectiveness evaluations). We can’t directly compare OP’s self-professed bar with GiveWell’s self-professed bar as if the units are interchangeable. This is a complexity that is not well represented in the CCM. The Worldview Investigations team has not tried to adjudicate such disagreements over GHD interventions.
I appreciate your attention to these details!
