Designing an Optimum Nudge

Tornado Exhibit at the Exploratorium

I’m sitting by a window looking out at a rainy Paris street, thinking of cultural differences between Paris and San Francisco, taking advantage of bad weather to do some writing. Over two decades ago, I did some ethnographic research a Exploratorium, looking at how different visitors interacted with the museum’s hands-on exhibits. I was looking for ways to improve the visitors’ experience, raise understanding of the phenomena they were observing. What I saw was different ways in which visitors experienced failure: p-prims that got in a way; folksy wisdom that caused confusion; lack of affordances that led to bottlenecks; permission giving that set up strange expectations; etc. The results of this study turned into a Master Thesis for UC Berkeley. Now, I would like to explore some of the ideas that surfaced during my Exploratorium research and apply them to design of nudging — carefully crafted affordances and perceptual cues that manipulated users into acting a certain way while maintaining the illusion of freedom of action. Let me start with a bit of history — a quick summary of some of the results of Exploratorium study. Permission Giving Two decades ago, “hands-on” exhibits were still novel in the museum world.…

Cheating by Design

The Road to Hell is Paved with Good Intentions. This year, the Metropolitan Transpiration Commission introduced the new Clipper Smart Card. Public transit riders all over the Bay Area can now use a convent piece of plastic to pay for their BART trains, buses, MUNIs, etc. Just swipe the Clipper Card past one of the little readers, and the gates open to let you in and out of the station or pay for the bus. The cards could be purchased in stores and vending machines all over the area—$2 cards are the minimum value cards. More money can be easily added to these cards at all BART train stations. The designers of Clipper Card envisioned happy riders and happy transpiration authority. “We’ll make it easy,” the designers said. “Easy to use, easy to fill up. And if the passengers accidently run out of money on their cards, we’ll allow them some small negative balance so they can leave the train station and pay for their rides later.” In the Bay Area, the cost of public transportation is pretty high and it’s highly dependent on how far you want to go: travel from City Hall to Airport, pay $8.10 for a…
