The term ‘moral weight’ is occasionally used in philosophy (David DeGrazia uses it from time to time, for instance) but not super often. There are a number of closely related but conceptually distinct issues that often get lumped together under the heading moral weight:
Capacity for welfare, which is how well or poorly a given animal’s life can go
Average realized welfare, which is how well or poorly the life of a typical member of a given species actually goes
Moral status, which is how much the welfare of a given animal matters morally
Differences in any of those three things might generate differences in how we prioritize interventions that target different species.
Rethink Priorities is going to release a report on this subject in a couple of weeks. Stay tuned for more details!
Thanks, that’s really helpful! I’d been thinking there’s an important distinction between that “capacity for welfare” idea and that “moral status” idea, so it’s handy to know the standard terms for that.

Looking forward to reading that!
