# Stuart_Armstrong comments on The Very Repugnant Conclusion

• Something like or or in general (for decreasing, continuous ) could work, I think.

• won’t converge as more people (with good lives or not) are added, so it doesn’t avoid the Repugnant Conclusion or Very Repugnant Conclusion and it will allow dust specks to outweigh torture.

Normalizing by the sum of weights will give less weight to the worst off as more people are added. If the weighted average is already negative, then adding people with negative but better than average lives will improve the average. And it will still allow dust specks to outweigh torture (the population has a fixed size in the two outcomes, so normalization makes no difference).

In fact, anything of the form for increasing will allow dust specks to outweigh torture for a large enough population, and if , will also lead to the Repugnant Conclusion and Very Repugnant Conclusion (and if , it will lead to the Sadistic Conclusion, and if , then it’s good to add lives not worth living, all else equal). If we only allow to depend on the population size, , as by multiplying by some factor which depends only on , then (regardless of the value of ), it will still choose torture over dust specks, with enough dust specks, because that trade-off is for a fixed population size, anyway. EDIT: If depends on in some more complicated way, I’m not sure that it would necessarily lead to torture over dust specks.

I had in mind something like weighting by where is the minimum utility (so it gives weight 1 to the worst off individual), but it still leads to the Repugnant Conclusion and at some point choosing torture over dust specks.

What I might like is to weight by something like for , where the utilities are labelled in increasing (nondecreasing) order, but if are close (and far from all other weights, either in an absolute sense or in a relative sense), they should each receive weight close to . Similarly, if there are clustered utilities, they should each receive weight close to the average of the weights we’d give them in the original Moderate Trade-off Theory.

• The utility of the universe should not depend on the order that we assign to the population. We could say that there is a space of lives one could live, and each person covers some portion of that space, and identical people are either completely redundant or only reinforce coverage of their region, and our aim should be to cover some swath of this space.
