We just start with a random utility distribution, then turn that into preferences by mangling it with an “ignorance factor”
The ignorance factor represents a disparity between the actual utility impact a candidate will have on a voter, and the assumed utility impact which forms the basis for her vote. Even with lots of ignorance, there’s still a significant difference in performance from one voting method to another.
In addition, I believe a lot of our ignorance comes from “tribal” thinking. If we have two parties (tribes), and each party must pick one side of any issue (abortion, guns, health care, etc.). Thus voters will tend to retroactively justify their beliefs about a given issue based on how it comports with their stated party affiliation. Note that this forced binary thinking is so powerful that we even have a party divide over the objective reality of climate change!
With a system like approval voting, candidates can easily run outside of the party system and still be viable. Thus they can take any arbitrary position on any issue, giving voters the freedom to move freely through the issue axes. A new offshoot of the GOP could form that is generally socially conservative and pro gun rights, but totally committed to addressing climate change. With 3-5 viable parties able to constantly adjust to changing realities, this is expected to reduce the amount of voter ignorance considerably, by allowing voters to consider issues which were once taken as given as part and parcel of their party affiliation.
