Cookie banners are mandatory for most websites because of the EU's General Data Protection Regulation (GDPR). The present study investigates if persuasive UI elements like dark and white patterns affect the user experience (UX) and perceived trust of people. In an online experiment with 52 participants, we compared the effects of a non-persuasive cookie banner with two types of dark pattern and a white pattern design. The perceived usability and overall UX were rated lower on the cookie banner with strong Dark Patterns than with Neutral Design. Dark Patterns were rated higher in positive emotions than the neutral design. Users with high technological affinity rated trustworthiness higher when interacting with strong Dark Patterns than with neutral design. The last two results could be evidence for the manipulative effect of Dark Patterns called Dark Patterns Blindness which raises the question: is it time to show more responsibility towards users and create an ethical awareness amongst stakeholders and designers? The practical implications of the study's findings are discussed.
