Purpose Studies on the coronavirus disease 2019 (COVID-19) tracing apps have mostly focused on how to optimize adoption and continuous use, but did not consider potential long-term effects of their introduction. This study aims to analyse whether the characteristics of the recent introduction of tracing apps may negatively impact individuals' attit...

Social computing has transformed the content industry. Content providers have changed from providing merely content to offering social content experiences that allow users not only to passively consume content but also to actively participate. As the latest development, social live streaming services (SLSS) have emerged that enable so-called co-int...

Owing to high functional complexity, trust plays a critical role for the adoption of intelligent decision support systems (DSS). Especially failures in initial usage phases might endanger trust since users are yet to assess the system's capabilities over time. Since such initial failures are unavoidable, it is crucial to understand how providers ca...

Artificial intelligence (AI) enables new opportunities for business-to-consumer (B2C) e-commerce services, but it can also lead to customer dissatisfaction if customers perceive the implemented service not to be fair. While we have a broad understanding of the concept of fair AI, a concrete assessment of fair AI from a customer-centric perspective...

Conversational agents (CAs) are often unable to provide meaningful responses to user requests, thereby triggering user resistance and impairing the successful diffusion of CAs. Literature mostly focuses on improving CA responses but fails to address user resistance in the event of further response failures. Drawing on inoculation theory and the ela...

Content website providers have two main goals: They seek to attract consumers and to keep them on their websites as long as possible. To reach potential consumers, they can utilize several online channels, such as paid search results or advertisements on social media, all of which usually require a substantial marketing budget. However, with rising...
Article
Many authorities currently use software-based risk-assessment instruments (SBRAIs) to assess a person’s potential to commit crimes (e.g. terrorism, sexual assault). SBRAIs promise better, faster, and more consistent decision-making than their paper-based predecessors. The underlying SBRAI classification schema is well-understood, but given the pote...

Digital value-added services (DVAS) represent a major opportunity for firms to create additional value for customers and differentiate themselves from competitors. However, many firms are struggling with how to develop DVAS. They often hire specialized innovation consulting firms to do this job but we know little about their secrets of success. To...
Article
Individuals' disclosure of personal health information (PHI) can hold substantial benefits for both users and providers, but users are often reluctant to disclose, even if they gain benefits such as better personalization. While previous research has dealt with message framing and information quality in a health-related context, factors have been o...

Owing to bounded rational decision-making, professional IS users often tend to resist new ISs by sticking with incumbent systems. Mainly due to misconceptualizations about the concept and methodological hurdles in isolating effects, to date, IS research has failed to provide empirical evidence of a fundamental tenet of the status quo bias (SQB): co...

Digital technologies have diffused into many personal life domains. This has created many new phenomena that require systematic theorizing, testing and understanding. Such phenomena have been studied under the Digitization of the Individual umbrella and have been discussed in the Digitization of the Individual (DOTI) pre-ICIS workshop for the last...
Article
Along with the miniaturization of digital devices, consumer health wearables (CHWs) further decrease the distance between users and devices, allowing users to continuously track their personal health information (PHI). While this provides more control to users, history has shown that users' potential concerns (e.g. privacy) can lead to devices not...
Article
Product-related and market-related uncertainties often cause users to defer from switching to new IT devices. There is a value of waiting (VoW) for users because waiting allows them to collect more information. At the same time, many IT switching decisions are increasingly complex due to increased connectivity and the resulting interdependencies be...

Social live streaming services (SLSS) have emerged as a new type of hedonic social media. SLSS allow users to watch and broadcast video streams in real-time, fostering sociability through synchronous communication via chat channels. While the extant literature has mostly examined producers’ use of SLSS, the consumer perspective has been underexplor...
Article
While Internet technologies have provided social networks for researchers as more open means to make their work available to other scholars, the traditionally closed, peer review-based publishing process has remained nearly untouched.

Based on big data, decisions can increasingly be drawn from data-driven analytics and algorithmic decision support. However, it remains unclear whether recommendations issued by computer algorithms are equally accepted by individuals as human advices. This is particularly intriguing given that big data entails various forms of ambiguous decision si...

Individual-level inertia exists if users stick to incumbent technologies even if better alternatives are available. Thus, inertial behavior fosters the continued use of current information systems rather than the adoption of new ones. Despite the growing research interest in inertia in recent years and its importance for users’ post-adoption decisi...

Recommender systems aim to support users in identifying the most relevant items. However, there are concerns that recommenders may imprison users in a "filter bubble" by recommending items predominantly known to them. On the other hand, providing unconventional items may increase risks of not meeting users' taste. Given this trade-off, we analyze t...
