HINTS: Health improvement through nudging techniques

Projectomschrijving

Gezonde eetgewoonten helpen ziekten zoals obesitas en hart- en vaatziekten te voorkomen. Veel Nederlanders hebben echter een ongezond voedingspatroon. Dit is grotendeels het resultaat van automatische, onberedeneerde keuzes voor ongezond voedsel, uitgelokt door een ‘obesogene’ voedselomgeving. In dit project onderzoeken we “nudges”: interventies waarin de automatische processen die een rol spelen in eetgedrag juist benut worden. Nudges passen de voedselomgeving op subtiele wijze aan zodat eetgedrag automatisch en onberedeneerd een gezondere kant op wordt gestuurd. Zo wordt gezonder eetgedrag bevorderd zonder dat dit het individu veel moeite of wilskracht kost, terwijl keuzevrijheid blijft gewaarborgd. In het project 1) identificeren we geschikte nudges, 2) onderzoeken we de psychologische mechanismen die inzicht geven in hoe nudges werken en 3) evalueren we de ethische aanvaardbaarheid en de impact van nudges op het veranderen van eetgedrag en gewoontes op de korte en langere termijn.

Samenvatting van de aanvraag

Healthy eating is crucial in the prevention and management of many chronic diseases, such as obesity, diabetes type 2, cardiovascular diseases and certain types of cancers. However, today’s food environment makes it hard to eat healthy and a large majority of the population eats less healthy than recommended. Unhealthy, palatable foods are widely available at low cost and generally present the default option. Resisting these kinds of default unhealthy choices requires effortful, conscious decisions, for which people only a have limited ability. It has been estimated that people make around 200 food decisions per day, of which about 70% results from non-reasoned, unconscious processes.Hence, most decisions are made mindlessly in response to salient cues in the environment. Despite overwhelming evidence from behavioral science that many behaviors result from automatic, intuitive processes, state-of-the-art health promotion interventions have not found solutions to deal with the non-reasoned nature of many health behaviors. Innovative interventions that acknowledge the nature of health decisions as being driven by automatic processes in response to specific environmental cues are urgently needed. We propose that the nudge concept should be underlying the design of a new generation of health promotion strategies. Nudges have been defined as simple changes in the presentation of choice alternatives that make the healthy choice the easy choice, and allow for decisions without much deliberation and without infringing on the autonomy of the individual. Nudge-like interventions that take advantage of the automatic nature of human behaviors are considered a superior alternative to existing health promoting interventions, with potential additional benefits in several domains including a) increased efficiency and decreased costs because the delivery of nudge-like interventions is generally cheaper and easier than currently available public health solutions, and b) reduced health inequality because nudge-like interventions do not rely on the communication and comprehension of complex information about health behavior change. The proposed program aims to identify and investigate effects and impact of ethically acceptable nudges to promote healthy eating behaviour. Three separate projects will be conducted. Project 1 identifies and justifies norms for responsible nudges in the context of healthy nutrition. A Nominal Group Technique and a survey among consumers is conducted to identify nudges that are deemed acceptable and desirable with different users and end-users. Current philosophical and practical ethical debates about nudging will be analyzed, exploring their relevance to the specific public and private contexts of food choices, and critical perspectives on current emphasis on nudging as a right response to unhealthy eating behavior will be explored. Project 2 investigates how and under what specific conditions nudges contribute to healthy diets. By means of laboratory experiments, more fundamental insight will be gained into the psychological processes and mechanisms by which nudges promote healthy diets. Project 3 evaluates the impact of nudges on long-term eating behaviour and habit formation. By means of controlled field experiments and natural experiments in real-life settings, insight will be gained into who will be reached with nudges and into the sustainability of nudging effects on behavior change and habit formation.
