Will Privacy Consent Actually Be Done Properly? Results from a Randomized Experiment in Privacy-Handling Flows
Demonstrably Informed Consent in Privacy Policy Flows: Evidence from a Randomized Experiment
HCI Today summarized the key points
- •This article discusses research on how to verify whether people truly understand the content during the privacy policy consent process.
- •The research team showed 293 parents the privacy policy of a children’s learning app and compared six different screen formats using comprehension quizzes.
- •A format that encouraged slower reading—such as slide-based presentation and sectioned layouts—passed the comprehension threshold better on the first attempt.
- •The approach of rereading after getting something wrong and then retaking the quiz helped improve scores, and the version that combined sectioning with explanations was especially effective.
- •However, these approaches can take more time and increase burden, so the degree to which they support understanding must be adjusted to the situation.

Why Read This from an HCI Perspective
This article shows that privacy consent should be designed not around whether users click the consent button, but around what users actually understand. For HCI and UX practitioners, it prompts thinking about what interaction mechanisms make long terms more readable, and what trade-offs those mechanisms create in terms of time, fatigue, and drop-off. For researchers, the study is an interesting reference point for experimental designs that connect comprehension measurement with consent-flow design.
CIT's Commentary
The core of this study is treating the terms not as a ‘document,’ but as an ‘interaction.’ In particular, slide-based presentation, dividing content into sections, and enabling re-learning and re-attempts are not just ways to show more information—they are mechanisms that make users pause briefly and look again. In systems where safety or accountability matters, these small pauses can make a big difference. However, when implementing in real products, you should not only look at improved comprehension; you also need to design for how much longer the consent flow becomes, where users give up, and how you will leave intervention paths in different failure modes. In the context of Korean mobile services, it may be more natural to use summary cards, key-item highlights, and choice-based explanations rather than asking users to read long text. So rather than transplanting global research findings directly, you likely need to reinterpret them to match actual user behavior patterns.
Questions to Consider While Reading
- Q.In a consent flow, what level of minimal ‘friction’ is appropriate to improve comprehension?
- Q.In real services, how much would a re-attempt (retake) structure increase drop-off rates, and how could you measure the associated costs?
- Q.For domestic services like Naver and Kakao, what form of explanatory interaction would be more effective than long terms?
