Kahneman makes a clear error

In his chapter called "Two Selves," Kahneman deems it an error for people to judge and experience by their memory of it, rather than their experience of it. They should, per Kahneman, evaluate a painful experience by the integral of experienced pain, and not by their memory, which is likely to evaluate the end of the experience as more significant than the experience as a whole. I say Kahneman is simply using the wrong integral: The experience lasted 10 minutes, but the memory of it will last for my entire lifetime. Why shouldn't I count the latter as more important than the former?

(Anyone interested in co-authoring a paper on this?)

UPDATE: Hmm, not sure if this is a retraction: "Life satisfaction is not a flawed measure of their experienced well-being, as I thought some years ago. It is something else entirely." p. 397
