Jung and Mellers (2016) Look at US Attitudes Towards Nudges

Janice Y. Jung and Barbara A. Mellers, “American Attitudes toward Nudges.” Judgment and Decision Making 11(1): 62-74, January 2016.

• System 1 nudges are those that take advantage of our relatively automatic, unthinking mechanism for making decisions – canny default settings are an example of a System 1 nudge.

• System 2 nudges enhance our cognitive abilities, perhaps by providing more information – calorie counts on food items are an example of a System 2 nudge. 

• Study 1 conducted by Jung and Mellers looks at nine System 1 nudges and four System 2 nudges, in an internet-based survey (n=250). Subjects are asked if they are for or against nudges, and then rate the intensity of their feelings on the subject. (If you are unsure, you will be asked to explain why!) Subjects also rate nudges on various scales, such as whether they are a threat to autonomy. 

• Jung and Meller's Study 2 manipulates the “framing” of the nudges, sometimes emphasizing individual effects, sometimes social effects; sometimes highlighting the benefits, sometimes highlighting the avoidance of costs. Attitudes also are collected about companies that institute nudges. 

• System 2 nudges receive more support than System 1 nudges – but one System 2 nudge, where government provides a website that tracks people’s expenditures on food, energy, and so on, is disliked in a System 1-like manner. 

• Also disliked are opt-out organ donation lists, those misleading white lines on Lake Shore Drive, one-click charitable donation opportunities at store check-outs, and credit card online payment mechanisms that default to fully paying off the debt. 

• Empathic folks tend to support System 1 and System 2 nudges; conservatives and individualists tend to oppose both types of nudges. (“Reactant” people oppose System 1 nudges.) System 2 nudges are viewed as more effective, though evidence generally supports the superior effectiveness of System 1 nudges. 

• Framing doesn’t matter much on average, but does matter with some sub-groups; for instance, “reactant” people oppose nudges more strongly when the frame points out the individual costs of not going along. Feelings about companies that nudge basically track the feelings about the nudges the companies implement.
