Utility function estimator

I am writing a program to estimate someone’s utility function in various common situations. My primary application is to find out how average humans actually devalue utility over time—is it hyperbolic as claimed?

However, the same program could be used to make a proxy for yourself in various situations.

Someone requested a top-level post going into more detail on how I’m working on it (if people donate money I’ll work faster), what exactly it does, and what you might use it for. I’m a slow writer and don’t really want to put the effort into a top-level article unless more than one person is interested. I thought the new discussion forum would be ideal to gauge interest.
