Thanks--could you elaborate on what was fixed? I am a newbie here. Was it something I could have seen from the preview page? If so, I will be more careful to avoid creating unnecessary work for mods.
Scott Alexander's "Meditations on Moloch" presents several examples of PD-type scenarios in which honor/conscience-style mechanisms fail. Generally, honor and conscience simply provide additive terms to the entry of the payoff matrix. These mechanisms can shift the N.E. to a different location, but don't guarantee that the resulting N.E. will not produce negative effects of other types. This post was mainly meant to provide a (hopefully) intuitive explanation of N.E.
