A system configured for: (A) identifying a first party of a plurality of parties as one of an excluded group of parties; (B) identifying a candidate group that includes each of the plurality of parties other than the excluded group of parties; (C) receiving, from the first party, a first-party utility value that the first party would associate with at least one of a plurality of different outcomes; (D) receiving, from a second party, a second-party utility value that the second party would associate with at least one of the plurality of different outcomes, the second party being part of the candidate group; and (E) determining which particular one of the plurality of outcomes should be selected based primarily on a set of utility values that comprises the second-party utility value. Step (E) may be made without substantially considering the first-party utility value, and Step (B) may be made without substantially considering the first-party utility value.
