A lot of what Daniel Kahneman says here is written about in Daniel Gilbert’s book (Stumbling On Happiness) that I’ve been reading. If you remember, I posted another talk from Kahneman before about why moving to California won’t make you happy, and now he talks here about how actual experience and memory are often not linked directly. Our memory of an experience can overcome the entire experience altogether, and if the memory is marred by a bad event at the very end, it really doesn’t matter how good the rest of it was — we will think it was a bad experience.
