I could see this argument going the other way. If a post is loved by 45% of people, and meh to 55% of people, then if everyone use target karma, the meh voters will downvote it to a meh position. As you say, the final karma will become people’s median opinion; and the median opinion does not highlight things that minorities love.
However, if everyone votes solely based on their opinion, 45% will upvote the comment, and 55% won’t vote at all. That means that it will end up in an overall quite favorable spot, as long as most comments are upvoted by less than half of readers.
I think both systems would have to rely on some people not always voting on everything. The nonTK system relies on there being large variability in how prone people are to voting (which I think exist; beware the typical mind fallacy… maybe another poll on how often people vote?) whereas the TK system relies on people abstaining if they’re uncertain about how valuable something is to other people.
