    Cette thèse explore l'espace de conception des nudges numériques et leurs effets sur les utilisateurs dans trois domaines d'application : la vie privée en ligne, l'utilisation des médias sociaux et les dons de charité en ligne. Après le chapitre d'introduction, une revue systématique de la littérature liée aux études empiriques sur les nudges numériques est menée, révélant le paysage actuel de la recherche. Ensuite, une expérience en ligne et une étude descriptive sur le terrain sont utilisées pour démontrer l'efficacité des nudges numériques dans la sensibilisation à la protection de la vie privée en ligne pour les utilisateurs de certaines plateformes digitales. Le chapitre suivant utilise une expérience de terrain, menée en ligne, pour modifier l'architecture des choix numériques d'une plateforme de médias sociaux populaire. Cette étude évalue les régimes restreints des fils d'actualité et leur impact sur les comportements et les expériences des utilisateurs. Le cinquième chapitre est une expérience factorielle en ligne concernant les dons de charité avec des enjeux monétaires réels. Cette dernière étude examine systématiquement les combinaisons de plusieurs nudges numériques sur les comportements de don en ligne des utilisateurs et leurs attitudes associées en matière de manipulation et d'autonomie. La thèse présente plusieurs contributions liées aux nudges numériques et à l'architecture de choix. L'examen systématique met en lumière plusieurs pistes de recherche ouvertes pour le domaine qui appellent à des recherches futures. L'expérimentation liée à la confidentialité en ligne montre que les nudges numériques pourraient améliorer les interactions des utilisateurs avec les conditions et les politiques de confidentialité, sans toutefois renforcer leur mémorisation de ce qu'ils ont accepté. L'expérience sur le terrain concernant les régimes des fils d'actualité des médias sociaux démontre leur impact sur le temps passé sur la plateforme de médias sociaux, mais ces interventions de conception s'accompagnent d'expériences positives et négatives pour l'utilisateur. L'expérience factorielle en ligne relative aux dons de charité révèle que certaines combinaisons de nudges numériques augmentent les dons, mais ces nudges suscitent également des inquiétudes chez les utilisateurs quant aux menaces pesant sur leur autonomie et leur sentiment de manipulation. Ensemble, les chapitres de la thèse mettent en évidence l'impact complexe des nudges numériques sur le comportement et les attitudes dans plusieurs domaines d'application pertinents. ABSTRACT: This dissertation explores the design space of digital nudges and their effects on users in three application domains: online privacy, social media usage, and online charitable giving. After the introductory chapter, a systematic review of empirical studies on digital nudging is conducted, uncovering the current research landscape. Next, an online experiment and a descriptive field study is used to demonstrate the effectiveness of digital nudges for enhancing the online privacy awareness of users for popular online services. The next chapter uses an online field experiment to alter the digital choice architecture of a popular social media platform. This study evaluates restricted newsfeed diets and their impact on user behaviors and experiences. The fifth chapter is an online factorial experiment concerning charitable giving with real monetary stakes. This last study systematically investigates combinations of several digital nudges on users' online donation behaviors and their associated attitudes around manipulation and autonomy. The dissertation extends several contributions related to digital nudging and choice architecture. The systematic review illuminates several open research avenues for the domain at large that call for future research. The experiment related to online privacy awareness shows that digital nudges could elevate user interactions with terms and privacy policies, although without bolstering users' recollections of what they have agreed to. The field experiment concerning social media newsfeed diets demonstrates their impact regarding time spent on the social media platform, but these design interventions come with both positive and negative user experiences. The online factorial experiment related to charitable giving reveals that some combinations of digital nudges increase donations, but these particular nudges also invoke users' concerns about autonomy threats and an experienced sense of manipulation. Together, the chapters of the dissertation highlight the complex behavioral and attitudinal impact of digital nudges across several relevant application domains.

    The rise of intelligent technologies and social media : implications for human-technology relationships

    Cette thèse explore les dynamiques évolutives des relations humains-technologie à travers trois articles distincts, mettant l'accent sur les implications des technologies intelligentes et des médias sociaux. Le premier article évalue de manière critique l'anthropomorphisme dans l'IA, en explorant sa conceptualisation théorique et son application dans des domaines tels que l'informatique, la robotique, la psychologie et le marketing. Malgré l'utilisation généralisée de caractéristiques humanisées dans les technologies, une compréhension globale de l'anthropomorphisme dans l'IA fait défaut. Pour pallier cela, cet article propose un cadre conceptuel et recommande les meilleures pratiques pour les recherches futures, en particulier dans le domaine du marketing et du comportement du consommateur. Le deuxième article adopte une perspective relationnelle pour analyser les impacts des assistants IA anthropomorphiques, tels qu'Alexa, sur les consommateurs. Les résultats des enquêtes et des expérimentations de terrain révèlent que si l'anthropomorphisme de l'IA peut enrichir l'expérience utilisateur, il peut également susciter des menaces à l'identité humaine, renforcer les préoccupations liées à la confidentialité des données et diminuer le bien-être. Cependant, la recherche dévoile également trois interventions pratiques pour atténuer ces effets indésirables. Le troisième article contemple les changements sociétaux induits par les réseaux sociaux. Il souligne que ces plateformes amplifient les valeurs individuelles de l’accomplissement et de la conformité. Cette affirmation est soutenue par une analyse de données secondaires, d'enquêtes consommateurs approfondies et d'expériences. De manière générale, cette thèse vise à éclairer les complexités des relations consommateur-technologie et leurs implications.
    ABSTRACT:
    This dissertation explores the evolving dynamics of human-technology relationships, emphasizing the implications of intelligent technologies and social media. The dissertation encompasses three distinct articles. The first article critically evaluates anthropomorphism in AI, exploring its theoretical conceptualization and application across fields like computer science, robotics, psychology, and marketing. Despite the widespread use of humanlike features in technologies, a comprehensive understanding of anthropomorphism in AI is lacking. As a remedy, this piece offers a conceptual framework and recommends best practices for future exploration, particularly in marketing and consumer behavior. The second article adopts a relationship-centric lens to analyze the impacts of anthropomorphic AI assistants, such as Alexa, on consumers. Findings from surveys and field experiments reveal that while AI anthropomorphism can enrich the user experience, it can also elicit identity threats for the users, intensify data privacy concerns, and diminish overall well-being. However, this research also unveils three practical interventions to mitigate these adverse outcomes. The third article contemplates the profound societal shifts induced by social media. It underscores that platforms like these amplify individual values of achievement and conformity. This assertion is backed by an analysis of a large set of secondary data, a consumer survey, and an experiment. In essence, this dissertation seeks to illuminate the complexities of consumer-technology relationships and their implications.

    Billions of people worldwide experience vulnerability in different ways. States, nonprofit and even private organizations develop offers to support vulnerable individuals. It is however unclear how to best encourage such individuals to engage with these offers that are designed to help them. We conducted a field experiment study, in the form of a direct marketing campaign. A total of 9002 randomly selected unemployed people received one of six support messages by SMS, informing them about trainings that could help them find a new job. The support message was either a plain message plus a link to the courses (control), or communicated additional monetary or psychological value. We measured whether participants engaged with the offer. The results showed that all the support messages that communicated additional value generated less engagement compared to the plain control message. Moderation analyses using primary and district-level secondary data associated to vulnerability further highlighted that the level of vulnerability indeed enforces this tendency to mistrust value communicated in messages. The findings suggest that for vulnerable people a more defensive, careful, communication approach is required to foster engagement in well-intentioned offers.

    It is unclear whether knowledge about a customer’s current sustainable behaviours, such as their choice of lightbulbs or travel mode, allows us to predict the sustainable behaviours they will carry out in the future. We address this in a large longitudinal study (N = 2177) where participants provided self-reports on electricity-, heating- and mobility related consumption at two separate times, three years apart. The results highlighted a high level of temporal consistency, whereby carrying out one sustainable behaviour predicted consumers would be carrying out the same behaviour three years later. However, sustainable behaviours generally did not drive other different sustainable behaviours years later (i.e. no spillover). In fact, isolated instances of spillover emerged only between different kinds of mobility-related consumption among consumers with high environmental values. Overall, the findings indicate a high degree of consistency in sustainable behaviour even years apart, and limited spillover from one sustainable behaviour to another.

    Artificial intelligence assistants (AIAs) such as Alexa are prevalent in consumers’ homes. Owing to their powerful artificial intelligence, consumers may perceive that AIAs have a mind of their own, that is, they anthropomorphize them. Past marketing research points to beneficial effects of AIA anthropomorphism for consumers and companies, while potential harmful effects have not been empirically explored. In examining both beneficial and harmful effects, this paper adopts a relationship perspective. Indeed, consumers spend large amounts of time with their AIAs, potentially developing a relationship over time that builds on an exchange of benefits and (psychological) costs. A preliminary survey and user interviews, a field study and a field experiment with AIA users show that AIA anthropomorphism may threaten users’ identity, which disempowers them, creates data privacy concerns and ultimately undermines their well-being. These harmful effects particularly emerge in close, long relationships. The field experiment uncovers three empowering interventions which attenuate harmful effects of AIA anthropomorphism in relationships with consumers. With AI-powered technologies taking larger roles in our daily lives, our research highlights key future directions to investigate the permanent ongoing nature of the consumer–AI relationships.
