Another downside is that while it does prevent spoilers, RCV doesn’t prevent other forms of vote splitting. It keeps an unlikely outlier candidate from tanking the consensus candidate, but it doesn't prevent splits between three or more viable candidates. This is especially problematic because one most important supposed qualities of RCV, according to its advocates, is that it makes more candidates more viable.

It also gets rid of people who are too dumb to understand RCV. Hee hee. Intellectual filter on the voting population. :)

I very much want dumb people to have representation.

No, you don't want dumb people to have representation, because idiots will spread misinformation (everything from climate change being fake to masks being unnecessary) and adopt corrupt practices to garner their votes. Smart people are less vulnerable to misinformation.

You want people who believe science, have a sense of foresight for several years, understand international politics, and how resources and economics work to decide the future of the country.
