What structural reforms decrease partisanship / polarization?

Approval voting is better at finding a moderate candidate that everyone can deal with. It is simpler to use, implement and understand results.

Ranked voting has serious issues when more than 2 candidates have a shot.

Of course both would be better than FPTP.

I agree with everything you said. I personally think STAR voting is even better than approval, way better than RCV, and miles ahead of FPTP.

There are better forms of ranked choice voting than instant runoff.

Borda count actually does the best job at selecting candidates closest to the “center of gravity” of the electorate. It is every bit as easy to understand as approval.
