This study aims to address whether Swedish e-commerce websites use dark patterns in cookies and, if so, how they do it and what users think is ethically acceptable regarding this matter.

Previous research has mainly focused on identifying dark patterns and the user experience aspect of cookies and dark patterns. In this study, a framework based on definitions of dark patterns from Brignull (u.å.b) and Forbrukerrådet (2018), was used to identify dark patterns in cookies through a content analysis on 30 of the e-commerce websites in Sweden with the highest economic turnover. What users consider to be ethically acceptable is examined through a survey with a total of 111 respondents.

The results show that dark patterns are used to a large extent on Swedish e-commerce websites and out of eight examined dark patterns, an average of five dark patterns per website were identified. The results also indicate that the majority of users thought that dark patterns in cookies are ethically unacceptable, even though a certain part of the respondents also seemed to be more neutral set in the matter.
