You got it-- a perfectly rational voter ("rational" meaning "optimizing according to game theory") will use only 0 or 10 scores (assuming simplifying assumptions, of course).

lot of the kids aren't really that technical, so deep subjects (like P vs NP etc) are probably a bit of a waste on them.
I didn't get into P vs NP until my second year of college.
Thanks for the reply. I'd point out that other countries with plurality-elections have managed to acquire more than two dominant (well, prominent) political parties. See Canada, for example.
Canada is a parliamentary system. Turns out to behave differently.
As for alternatives to plurality, approval voting might be better. Instant-runoff ranking might be even better still, but would require some changes to existing voting processes, and education of the electorate. Arrow's Impossibility Theorem shows that no voting method can be perfectly fair in all situations. However, I recall that runoffs are the best compromise.
Arrow's theorem doesn't actually cover approval voting, since it doesn't quite fit the requirements (short answer, Arrow's theorem has a built-in assumption that the choice function is deterministic based on individual voters' ordered preferences, while approval voting adds an additional voter preference that is not deterministic, the cut-off between "like" and "dislike". You can model this as an additional parameter, but all the ways I know of to modify Arrow's theorem in this way have problems.) Nevertheless, the basic point of Arrow's theorem is important: don't try to find a system that's perfect in every possible case, just look for one that works better in real-world cases.
Run-off voting is, indeed, much better than plurality-takes-all. I will argue that it may be better, but still has problems (e.g., a centrist candidate who would beat either of two opposite wing candidates on a one-on-one election could be eliminated in the first round). But, possibly more important, approval voting completely utterly simple.
Another system that is straightforward is simple numerical scoring: everybody scores all the candidates from zero to 10, and you add up all the scores, highest number wins. That is also trivial to explain. Fast to count votes (only one pass, consisting of addition) but can't be done without modifying existing equipment. (Oddly, this is mathematically identical to approval voting if voters are perfectly rational. But voters aren't, of course.)
You can buy a whole actual phone for the price of that ugly-ass bag.
The US is a two party system.
I know what you mean, but strictly speaking, it's not a "system."
It is the net result of Duverger's law, which is a consequence of the voting system where the plurality takes all; which tends to suppress third parties.
If you want to see more than a binary choice, advocate for a system that does not squeeze out third parties. My choice would approval voting, a system which has the advantage of not needing any change whatsoever in the existing voting process, only requiring removing the current constraint that if a person votes for more than one candidate, their vote is discarded.
EU here... Housing in the city is so expensive that minorities can't find a home there. Hope that helps.
So they end up living in slums. Cities have slums we just don't like to think about them. Occasionally right wing media will talk about them because there's a lot of Filth and crime like you would expect when everybody is dirt poor and being abused. Although honestly they don't even really bother with that anymore because they found they can just make shit up about actual nice cities and right-wing idiots will believe literally anything.
I mean they had a guy on Fox News pretending to be antifa who literally is the same guy who was pretending to be a violent black lives matter protester a few years ago. That is the level we are at people.
The hilarious thing is that the suburbs aren't sustainable. Even though people in the inner city make very little money and get treated like shit there's a lot of them because of how well, population density works and so the poor people in the inner cities subsidize the well-to-do people in the suburbs. Without the subsidies the suburbs can't pay for their roads in schools and cops.
It's basically an elaborate way to keep some form of slavery going even though we're not technically allowed to do that anymore. But again it's not sustainable because we are gradually breaking down the economy so much that there just isn't enough money to go around anymore. Capitalism is being dismantled in favor of a weird feudal system that benefits the very very top 10,000 or so people on the planet
Yeah, but you see, from marketing perspective what sounds better? The Line or the Dot or the Pimple?
They had these 3 choices, they made the more sensible one even though it has nothing to do with a good or sensible city outline.
