I was trying to use the lower and upper estimates of 5*10^-5 and 10, guessed for the moral weight of chickens relative to humans, as the 10th and 90th percentiles of a lognormal distribution. This resulted in a mean moral weight of 1000 to 2000 (the result is not stable), which seems too high, and a median of 0.02.

1- Do you have any suggestions for a more reasonable distribution?

2- Do you have any tips for stabilising the results for the mean?

I think I understand the problems of taking expectations over moral weights (E(X) is not equal to 1/E(1/X)), but believe that it might still be possible to determine a reasonable distribution for the moral weight.

Thanks for the post!

With a loguniform distribution, the mean moral weight is stable and roughly equal to 2.
