Reciprocal Score Voting: Difference between revisions
→Analysis
Line 118:
Since the incentive for betrayal is eliminated, but the rewards for collaborating are preserved, Reciprocal Score Voting minimizes concerns with Chicken Dilemma scenarios. Thus in any sufficiently large mutual majority scenario, the likelihood of either A or B winning will be very large (although not guaranteed due to the non-ranked nature of the system).
=== Reverse spoiler effect ===
RSV suffers from a "reverse spoiler effect" in which a large faction may lose by not supporting a smaller faction. This can be a major problem when the smaller faction is a group with fringe or too radical beliefs compared to the main faction.
Since such fringe groups would likely be universally hated by every other faction, one way to partially address this is to additionally adjust the reciprocity ratios to include the total ratings given to each faction, that is, if a fringe faction gets an overall low mean score, then that low mean score is used to lower the penalty of not reciprocating with that faction. This way, sufficiently fringe factions largely give asymmetric support towards more mainstream factions. Between similar mainstream factions, which would receive similar overall mean scores, the effect cancels out and RSV proceeds as normal.
