The paper, “23 Ways to Nudge: A Review of Technology-Mediated Nudging in Human-Computer Interaction,” discusses the application of nudging, a concept introduced by Thaler and Sunstein, in the Human-Computer Interaction (HCI) field. This idea utilizes subtle modifications in choice architecture to influence people’s behavior. The study systematically reviews HCI research to define the design space of technology-mediated nudging, identifying 23 mechanisms across 6 categories, addressing 15 cognitive biases. It aims to understand the effectiveness of these nudges and their ethical implications, offering a comprehensive framework for implementing behavior change through technology.

Key points to consider:

• Introduction of nudging in HCI, inspired by Thaler and Sunstein.
• Systematic review leading to the identification of 23 nudging mechanisms.
• Nudges categorized into 6 groups, leveraging 15 cognitive biases.
• Presentation of a framework for technology-mediated nudging.
• Discussion on the effectiveness and ethical implications of nudges.

One-sentence summary:

The paper presents a thorough investigation into technology-mediated nudging within HCI, outlining 23 mechanisms across 6 categories to address behavioral change, focusing on effectiveness and ethical considerations.
