We also seem to crave more variety at the point of decision than we will actually desire down the road. When I was young, for example, I was obsessed by the Kellogg’s variety packs of cereal. Wooed by the sight of the Apple Jacks and Frosted Flakes jostling up against each other, I would clamor for my parents to buy the largest package on offer, a towering block of shrink-wrapped goodness. Having raced through my favorites, however, I would find my liking gradually diminishing, from dizzy Applejacks heights to the sad denouement of a few sparse clusters of Special K and All-Bran, which often went unconsumed, dying a slow death in a shroud of plastic. My parents would, of course have been better off simply buying a few boxes of my favorites, which I would reliably eat every day.
