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
