comparing the configuration of privacy settings on social network sites based on different Default Options
Hawaii International Conference on System Sciences, 2015Co-Authors: Markus TschersichAbstract:Current privacy research in the context of social network sites is based on the assumption that all entered personal information is public available by Default. Literature from the fields of Default settings and sharing behavior in social network sites lacks empirical insights how restrictive privacy Default settings, that do not share personal information without the explicit decision of the users, influence their behavior. To gain empirical insight, a social network site privacy interface prototype with 14 different privacy settings was built to investigate in an experimental setting the influence of the preselected Option on (1) the configuration behavior of the privacy settings, (2) the deviation from the Default Option, and (3) the size of deviation from the Default Option. In general, the results of our test show that users having restrictive privacy Options as the preselected Option significantly differ from users having permissive Default privacy Options because they are more influenced by the status quo bias and anchoring effect.

are experienced people affected by a pre set Default Option results from a field experiment
Journal of Environmental Economics and Management, 2012Co-Authors: Åsa Löfgren, Peter Martinsson, Magnus Hennlock, Thomas SternerAbstract:The objective of the present paper is to investigate the robustness of the well-known result that pre-set Default Options determine people's choices. We do so by conducting a field experiment among environmental economists attending a large international conference on environmental economics. The participants were, at the time of registration, randomly allocated to different treatments related to carbon offsetting. What differs from earlier Default studies is that our subjects have good knowledge about the good at hand. We investigate whether the choices of these experienced individuals are affected by a pre-set Default Option, and we also study the effect of a treatment with no pre-set Default Option. Our results, together with previous findings, indicate that the effect of a Default Option attenuates with experience.

Does experience eliminate the effect of a Default Option? - A field experiment on CO2-offsetting for air transport. New title (when published): Are experienced people affected by a pre-set Default Option - Results from a field experiment
2009Co-Authors: Åsa Löfgren, Peter Martinsson, Magnus Hennlock, Thomas SternerAbstract:Earlier research has shown that using a Default Option has a decisive effect on individuals’ choices. In many cases, however, the low proportion of subjects who switch from the pre-set Default Option might partly explained by inexperience with the goods or services offered, and high transaction costs for switching. By conducting a natural field experiment when environmental economists registered on the web to a conference, the Default Option to offset CO2 emissions was randomly pre-set. Either the participants had to opt-in to offset, opt-out to offset or there was no Default Option, i.e. an active choice had to be made with no implicit “guidance” from the Default. We used experienced subjects and had low transaction costs of switching. Our findings show that the Default has no significant effect on the decision to offset.

comparison of three nudge interventions priming Default Option and perceived variety to promote vegetable consumption in a self service buffet setting
PLOS ONE, 2017Co-Authors: Rasmus Friis, Annemarie Olsen, Heather Hartwell, Laurence Depezay, Caterina Dinnella, Laure Saulais, Erminio Monteleone, Laurits Rohden Skov, K M Appleton, Agnès GiboreauAbstract:Background: Dietary choices in out-of-home eating are key for individual as well as for public health. These dietary choices are caused by a wide array of determinants, one of which is automatic decision-making. Nudging is attracting considerable interest due to its understanding and application of heuristic biases among consumers. The aim of this study is to test and compare three nudges in promoting vegetable consumption among test persons in a food lab-based experiment. Methods: The initial sample consisted of 88 participants recruited in Copenhagen, Denmark. Each study participant was randomly assigned to one of the three experiments: priming, Default and perceived variety. The priming arm of the experiment consisted of creating a leafy environment with green plants and an odour of herbs. In the Default arm of the experiment, the salad was pre-portioned into a bowl containing 200g of vegetables. The third experiment divided the pre-mixed salad into each of its components, to increase the visual variety of vegetables, yet not providing an actual increase in items. Each individual was partaking twice thus serving as her/his own control, randomly assigned to start with control or experimental setting. Results: The Default experiment successfully increased the energy intake from vegetables among the study participants (124 kcal vs. 90 kcal in control, p<0.01). Both the priming condition and perceived variety reduced the total energy intake among the study participants (169 kcal, p<0.01 and 124 kcal, p<0.01, respectively), mainly through a decrease in the meat-based meal component. Conclusions: Considerable progress has been made with regard to understanding the use of nudging in promoting a healthier meal composition, including increasing vegetable intake. This study suggests that the nature of a nudge-based intervention can have different effects, whether it is increasing intake of healthy components, or limiting intake of unhealthy meal components. This work has demonstrated that consumer behaviour can be influenced without restricting or providing incentives for behaviour change. The present findings have promising application to the foodservice sector.
