Does buffet choice architecture affect intake? The effect of relocating butter at a breakfast buffet on food intake

The aim of this study was to investigate if a changed default reduces the intake of butter among students at a breakfast buffet. Students were divided into two groups and served themselves from a breakfast buffet. The control group was offered a buffet where the butter was easily accessible, whereas the intervention group was offered a buffet where a request had to be made for butter. Single packed portions of butter taken from each part of the buffet, the number of students, and the number of habitual users in each group were recorded. At the regular buffet, 67 of 115 students were habitual butter users and 81 packs of butter were taken. At the buffet with the changed default, 16 of the 56 students were habitual butter users. Seventeen packs of butter were taken from the buffet. Slightly displacing butter at a breakfast buffet and forcing students to ask for that option significantly reduced uptake.     

If It Works,I like It: Consumer Acceptance of Food-Related Nudging

Abstract

The aim of the current study is to investigate factors that influence consumer acceptance of food-related nudging. Previous studies indicate that perceived effectiveness may positively influence acceptance of nudging, while limited freedom of choice may reduce acceptance. On this basis, acceptance, perceived effectiveness and perceived limited freedom of choice were measured for 11 different food-related nudges in a national representative sample of 455 adults. Five of the nudges were variations of placement alteration, while six were variations of informational labeling. Perceived effectiveness was identified as a significant positive predictor for acceptance of all of the investigated nudges (p?<?0.001), while perceived limited freedom of choice decreased acceptance of all investigated nudges (p?≤?0.02). Perceived effectiveness was the strongest predictor for acceptance of all types of nudges (β-values from 0.55 to 0.75), yet perceived limited freedom of choice was also a significant factor (β-values from ?0.07 to ?0.23).     

Nudging using the ‘dish of the day’ strategy does not work for plant‐based meals in a Danish sample of adolescent and older people

Adequate nutrition is an important factor for health and well‐being in adolescents and later years. Fruits and vegetables are part of a healthy diet as important source of nutrients, but their intakes are lower than the recommendations in European countries. This study aimed to compare the choices made by adolescents and older people between three similar dishes, one based on meat, one on fish and one on vegetables, in two different conditions: a neutral (control) situation and an intervention situation in which the vegetable‐based meal was designated ‘dish of the day’. The comparisons of choices will be made within the same age group (adolescents in the control group vs. adolescents in the intervention group; older people in the control group vs. older people in the intervention group). A quasi‐randomised field trial design was used with a sample of 94 adolescents (aged 10–19 years) and 97 older people (aged ≥65 years), who were randomly allocated to intervention or control groups. In the control situation participants were asked to choose between three similar meals, one meat, one fish and one the VeggiEat dish. In the intervention, the VeggiEat dish was labelled the ‘Dish of the day’. All dishes were provided free of charge, displayed side by side in the same order and served in same portions. The dish choices showed no differences between the control and intervention groups in both age groups, and no differences were found among the other variables analysed. This nudging strategy, ‘dish of the day’, seems not to work for the Danish sample of adolescents and older people. Future nudging studies with these populations are needed in order to find the best strategy to move adolescents' and older people's food habits toward a healthier pattern.     

Aisles of life: outline of a customer-centric approach to retail space management

The article argues that well-established principles of urban design are highly relevant for retail management and applicable in regards to a much needed customer-centric turn in space management within retailing management. In particular, supermarkets, hypermarkets and larger retail chains are governed by a space management tradition that heavily draws on principles of utilitarianism and instrumental rationality. Yet, any physical retail space accommodates a separate and distinctive, but not independent, social space which must equally be addressed if attractive retail spaces are to be grasped, created and maintained. In fact, the standardized and repetitive design of many larger retail environments such as supermarkets appears to build on uncontested traditions of space management and tenacious myths about consumer behaviour and preferences that are challenged as urban design studies are consulted. In reference to current urban design research, the article concludes by suggesting five propositions and measurements for the customer-centric quality of retail spaces that take as a starting point the appreciation of the social space that any retail space management presupposes.     

Communicative governance at work: how choice architects nudge citizens towards health,wealth and happiness in the information age

The article investigates the contribution of the nudging agenda to communicative governance and policy design through the extensive use of substantial communicative tools, complementing the use of procedural communicative tools associated with network facilitation and management in post-NPM thinking. This argument is carried out on three levels of analysis: I) the reliance on information as the primary tool of government and the corresponding reversal of the conventional governmental toolbox, II) the development and use of informational and communicative techniques guiding behaviour, and III) the instruments, interfaces and artefacts supporting the informational networks and flows of nudging interventions.
