I recently wrote about persuasion design on the web. In How Whole Foods “Primes” You To Shop, Martin Lindstrom gives some great examples of how grocery stores use persuasion design tactics to get people to buy more:

Ever notice that there’s ice everywhere in this store? Why? Does hummus really need to be kept so cold? What about cucumber-and-yogurt dip? No and no. This ice is another symbolic. Similarly, for years now supermarkets have been sprinkling select vegetables with regular drops of water–a trend that began in Denmark. Why? Like ice displays, those sprinkled drops serve as a symbolic, albeit a bogus one, of freshness and purity. Ironically, that same dewy mist makes the vegetables rot more quickly than they would otherwise. So much for perception versus reality.

I get it, and I understand that businesses need to make money, and this helps them do it. I don’t have to like it though, right?
