Abstract

When browsing the Internet, web users tend to accept all cookies even though this may threaten their online security. We apply a salience nudge and a framing nudge to the design of a cookie banner and test their individual and combined effectiveness in fostering rejection of unnecessary cookies in an online experiment (N = 358). The salience nudge makes the rejection button more visible, and the framing nudge phrases button labels as negations. Compared to the control with no nudges, which elicited a rejection rate of 27%, the salience nudge increased rejection rate by 7 percentage points (but p = 0.305), the framing nudge by 18 pp (p = 0.009), and the combination of the two by 53 pp (p < 0.0001). We also find that, when users are offered a customization option rather than the rejection button, only 3% of them select the option and reject non-necessary cookies. Finally, we explore how cookie rejection is related to the time users spend making the decision and to their personality traits. Our findings suggest that cookie rejection can indeed be fostered by an appropriate design of cookie banners and that legislation for protecting the online security of users should introduce specific design guidelines.

数字提示和 Cookie 拒绝：一项实验

在浏览互联网时，网络用户倾向于接受所有 cookie，即使这会威胁到他们的网络安全。我们在设计 cookie 横幅时采用了显著性暗示和框架性暗示，并在一项在线实验（N = 358）中测试了这两种暗示在促进用户拒绝不必要的 cookie 方面的单独效果和组合效果。显著性提示使拒绝按钮更加醒目，而框架提示则将按钮标签短语化为否定。与没有任何提示的对照组相比（对照组的拒绝率为 27%），突出提示使拒绝率提高了 7 个百分点（但 p = 0.305），框架提示提高了 18 个百分点（p = 0.009），两者结合提高了 53 个百分点（p < 0.0001）。我们还发现，当向用户提供定制选项而不是拒绝按钮时，只有 3% 的用户选择该选项并拒绝非必要的 Cookie。最后，我们探讨了拒绝 Cookie 与用户做出决定所花费的时间及其个性特征之间的关系。我们的研究结果表明，适当设计 cookie 横幅确实可以促进用户拒绝 cookie，而保护用户在线安全的立法应引入具体的设计准则。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
