    AI said, She said - How Users Perceive Consumer Scoring in Practice
    (Mensch und Computer 2023 - Tagungsband, 2023) Recki, Lena; Esau-Held, Margarita; Lawo, Dennis; Stevens, Gunnar
    As digitization continues, consumers are increasingly exposed to AI’s scoring decisions. However, we lack a thorough understanding of how users' misjudgments lead to a rejection of the system. Therefore, we must investigate the appropriation of such socio-technical systems in practice and how users describe their experience with algorithm-based scoring. To address this issue, we evaluated 1003 user reviews of an app of car insurance that calculates its premium based on the consumers' individual driving behavior. We find evidence that users develop their own folk theories to explain the algorithms with the help of situation-related experiences and that insufficient explanations lead to power asymmetries between consumers, the system, and the company. In particular, we uncover a fundamental conflict between computational risk assessment and the perceived agency to influence the score as a result of the different needs of the stakeholders involved.

    Negotiating Taste for Digital Depiction: Aligning Individual Concepts of Taste Perception in a Co-Design Process
    (Mensch und Computer 2022 - Tagungsband, 2022) Berkholz, Jenny; Esau-Held, Margarita; Stevens, Gunnar
    Taste is a complex phenomenon that depends on the individual experience and is a matter of collective negotiation and mediation. On the contrary, it is uncommon to include taste and its many facets in everyday design, particularly online shopping for fresh food products. To realize this unused potential, we conducted two Co-Design workshops. Based on the participants’ results in the workshops, we prototyped and evaluated a click-dummy smartphone app to explore consumers’ needs for digital taste depiction. We found that emphasizing the natural qualities of food products, external reviews, and personalizing features lead to a reflection on the individual taste experience. The self-reflection through our design enables consumers to develop their taste competencies and thus strengthen their autonomy in decision-making. Ultimately, exploring taste as a social experience adds to a broader understanding of taste beyond a sensory phenomenon.
