Our estimate uses Saulius’s years/$ estimates. To convert to DALYs/$, we weighted by the amount of pain experienced by chickens per year. The details can be found in Laura Dufffy’s report here. The key bit:
I estimated the DALY equivalent of a year spent in each type of pain assessed by the Welfare Footprint Project by looking at the descriptions of and disability weights assigned to various conditions assessed by the Global Burden of Disease Study in 2019 and comparing these to the descriptions of each type of pain tracked by the Welfare Footprint Project.
These intensity-to-DALY conversion factors are:
1 year of annoying pain = 0.01 to 0.02 DALYs
1 year of hurtful pain = 0.1 to 0.25 DALYs
1 year of disabling pain = 2 to 10 DALYs
1 year of excruciating pain = 60 to 150 DALYs
Depending on the allocation method you use, you can still have high credence in expected total hedonistic utilitarianism and get allocations that give some funding to GHD projects. For example, in this parliament, I assigned 50% to total utilitarianism, 37% to total welfarist consequentialism, and 12% to common sense (these were picked semi-randomly for illustration). I set diminishing returns to 0 to make things even less likely to diversify. Some allocation methods (e.g. maximin) give everything to GHD, some diversify (e.g. bargaining, approval), and some (e.g. MEC) give everything to animals.
With respect to your second question, it wouldn’t follow that we should give money to causes that benefit the already well-off. Lots of worldviews that favor GHD will also favor projects to benefit the worst off (for various reasons). What’s your reason for thinking that they mustn’t? For what it’s worth, this comes out in our parliament tool as well. It’s really hard to get any parliament to favor projects that don’t target suffering (like Artists Without Borders).
