My fellow US citizens can't even seem to wrap their minds around something as simple as ranked-choice voting, where instead of selecting the candidate you like best, you instead order the candidates based on how much you like them. It's an incredibly simple, intuitive change that has the potential to increase overall happiness with the results and disincentivize extremism. Yet it has been an uphill battle to get ranked-choice voting adopted, and some states and municipalities have even had to revert back to first-past-the-post voting after an outcry from voters. If voters can't wrap their heads around that, I hardly think they would be able to follow along with the mathematical principles outlined in the Quanta article.
