I just discovered Jonah Lehrer’s neuroscience blog, The Frontal Cortex. He has an interesting post on Grocery Shopping, in response to Mark Bittman’s recent New York Times article, Faster Slow Food.
Lehrer and Bittman explore the role of online technology in facilitating good food buying decisions. They’re a great follow up to my earlier post on Ezekiel Emanuel’s thoughts about the challenges of changing the culture of how we eat, and its impact on health and health care.
Bittman writes about the potential of online grocery shopping to make it easier to eat healthier, with less environmental impact: This is my fantasy about virtual grocery shopping: that you could ask and be told the provenance and ingredients of any product you look at in your Web browser.
You could specify, for example, “wild, never-frozen seafood” or “organic, local broccoli.” You could also immortalize your preferences (“Never show me anything whose carbon footprint is bigger than that of my car”; “Show me no animals raised in cages”; “Don’t show me vegetables grown more than a thousand miles from my home”), along with any and all of your cooking quirks (“When I buy chicken, ask me if I want rosemary”). You would receive, if you wanted, an e-mail message when shipments of your favorite foods arrived at the store or went on sale; you could get recipe ideas, serving suggestions, shopping lists, nutritional information and cooking videos. If poor-quality food arrived — yellowing broccoli, stinky fish, whatever — you would receive store credit without any hassle.
Lehrer adds another benefit: I think the most important improvement triggered by online supermarket shopping would be a reduction in impulse purchases.
Summarizing Walter Mischel’s research on self-control in young children, he writes: ...there was one simple way to dramatically enhance the self-control of four-year olds: Instead of giving them an actual marshmallow, show them a picture of a marshmallow. Although the practical consequences were the same – if they picked up the picture, they could get a tasty treat right away – the presence of the photograph was much less alluring, a much “cooler” stimulus. The end result is that most kids didn’t have trouble resisting the reward.
When we shop in a supermarket in person, we are confronted with an endless supply of “hot” stimuli, the shelves full of temptations. Maybe it’s Haagan-Dazs ice cream, or all those different kinds of potato chips. Perhaps our weakness is dark chocolate or Snickers or sour gummy bears. The point is that everyone has a favorite food, and seeing that food right in front of us makes it much harder to delay gratification.
Like those four-year olds, however, we can ignore that pint of Haagen-Dazs Dulce de Leche when we’re only looking at a picture of it. The stimulus has been cooled off by the online shopping experience – it’s an abstraction, a mere image – which allows us to make more responsible shopping decisions. The same logic also applies to non-food impulse purchases, from cashmere sweaters to electronics. (This suggests that whenever we feel our self-control slipping away we should leave the store immediately and go shopping online. If we still want to buy the sweater on our computer, then maybe it really is a good deal.)
So here’s a research proposal: someone should do a carefully controlled study looking at how our online supermarket decisions differ from our in person supermarket decisions. I’d bet that we make healthier choices when those tasty snacks are just photographs, shrunken to fit our computer screen.
Provenance (aka the story behind the food), practical information (cooking, nutrition, reviews), convenience, economic impact (personal and community) and personalization. Both articles address some of the core thinking behind Local Orbit and I highly recommend them.
