If I try this again next year I plan to use the exact same text and values on both sides, which hopefully will clear up most of that kind of issue. It doesn’t really fix marginal value, but I’m not sure that’s fatal to this kind of analysis- I can quote a reasonable price for an apple even though my marginal value of apples drops very fast by the time I hit three digits of apples. I could try and fix this by picking things I think people value vaguely the same but then we miss out on catching scope insensitivity.
