I [Nathan] think that shrimp QALYs and human QALYs have some exchange rate, we just don’t have a good handle on it yet.
I think being able to compare the welfare of shrimps and humans is far enough. I do not know about any interventions which robustly increase welfare in expectation due to dominant uncertain effects on soil animals. I would be curious to know your thoughts on these.
Oh, this [the point from Nathan quoted above] is nice to read as I agree that we might be able to get some reasonable enough answers about Shrimp Welfare Project vs AMF (e.g. RP’s moral weights project).
I believe there is a very long way to robust results from Rethink Priorities’ (RP’s) moral weight project, and Bob Fischer’s book about comparing welfare across species, which contains what RP stands behind now. For example, the estimate in Bob’s book for the welfare range of shrimps is 8.0 % that of humans, but I would say it would be quite reasonable for someone to have a best guess of 10^-6, the ratio between the number of neurons of shrimps and humans.
Hi Elliot and Nathan.
