Perhaps one way to improve the measurement would be to structure the question in terms of preference rather than direct measurement

This is a really cool idea. But even preference has issues. For example, I like contra dance (a kind of social dancing) a lot, and have a good time when I go. The feel in the moment is one of my favorite things. If you asked me, "would you rather be contra dancing" I would usually say yes. But if you look at my behavior, I don't actually go that often anymore, even when I do have free time. How do you tell the difference between me irrationally underconsuming something I enjoy vs me overestimating how much I enjoy it in posed comparisions?
