I will be specifically talking about this demo https://www.economist.com/interactive/2021/12/18/quadratic-voting https://www.economist.com/interactive/2021/12/18/quadratic-v... I don't think that quadratic voting is relevant for the case of "Many people need to answer a few shared questions" as it happens it elections. I believe it is for the case "one person needs to answer many questions" as it happens in polling. Of course it can be used in elections as a sort of preference voting, but its effect is to punish extreme opinions (you might be extremely opposed to Statement A but might also want to keep some credits to express your milder opinion about B, C, and D. (of course this also opens more venues for manipulating polling by adding duplicated similar questions...)

That UI is excellent, but it doesn't explain why it should be quadratic and not linear. At first glance, it seems actively bad, as I'm penalised for focusing on just a few issues! Unfortunately the linked article is paywalled. The motivating example in the QV papers I've just skimmed is more about people voting on a sequence of yes-or-no questions, buying some number of votes and being compensated afterwards each time. That's totally different from this one-shot, multiple-questions, fixed-budget example.
