The behavior graphs seem to use a linear "happiness" metric to judge the quality of outcome. I question this choice. It is not intuitive to me that some unit of happiness should cancel out a unit of misery when it comes to determining election outcomes.

There are arguments that need to be made before we can start comparing the quality of outcomes between voting methods.
