you don't have to have perfect information spread throughout a population to make good collective decisions amongst it. it's ok if much of the electorate is somewhat ignorant or poorly informed, as long as that's relatively uncorrelated (i.e., there's no systemic coercion of choice). but that's exactly what parties are designed to subvert to their advantage. so then, what we need to do is to do everything we can to move away from party politics, including better voting mechanisms and removing the outsized influence of money in politics.
