that person is STRATEGIC VOTERS, who are about 90% of the electorate. even if you want to vote honestly, you're still subject to the whims of other voters.
indeed, practically the only thing that matters in a voting method is the aggregate affect of what it achieves in light of other voters. YOUR vote will almost never make a difference. you could upgrade voting methods in exchange for giving up your right to vote, and you'd still be drastically better off.
That comes across as weirdly aggressive when you're referring to earlier in the same post. Like I'm dumb for not somehow seeing that before I finished my own post.
Also what's the definition of honesty for approval voting? Where am I supposed to draw the line?
The chart is pretty but I'm not trusting that chart without a lot more info.
it doesn't really matter how you define "honest". what matters is how people actually vote. the only really crucial distinction for "honest" versus "strategic" is that "honest" can't consider viability. in the simulations, we just use "approve everyone you like more than average". optimal strategy is to approve everyone you like more than the expected utility of the winner.

with FPTP, strategic voting means NOT voting for your favorite. so at the very least, you'd "vote for the person you'd normally support under FPTP, _plus_ everyone you like better".
but in real life, a lot of people will use intermediate scores.
