When the culture follows the normal distribution, the optimal decision rule for utilitarianism is not Borda but a scoring rule where the differences in the values given performance of scoring rules for the case of utilitarianism and for cultures following The γUT -index: Evaluating Decision Rules in terms of the Probability of Not Choosing the Worst Alternative. the β-index in the following sense: take a society {Uli}i∈N,l∈K, and let l be an alternative giving the highest utilitarian value. Theorem 4.1 does not assume any particular probability distribution over the individual utility values, or any society size. Note that implosion is not the maximum γMX-optimal decision rule since, in societies where the two individuals share the same ranking over the alternatives, implosion ./cache/work_ln56cwsp7ffppl4wxeq7osqfuu.pdf ./txt/work_ln56cwsp7ffppl4wxeq7osqfuu.txt
