Imagine buying flowers for a loved one. After selecting a bouquet, at checkout you discover that the site has sneaked a paid greeting card into your shopping cart. This is an example of a dark pattern, an interface designed to manipulate a user into behavior that goes against their best interests.

Sneak into Basket on, one of 1,818 instances of dark patterns found in Mathur et al. Despite not requesting a greeting card, one is automatically added at checkout for $3.99.
Workshop Topics

This four-hour online workshop (see agenda) at CHI 2021 will bring together a transdisciplinary group of design practitioners and researchers to discuss similarities in dark patterns across different domains and what to do about them. We will discuss two topics:

  • First, within the design community, how can designers address dark patterns through e.g., industry norm-setting, values articulation, and design education?
  • Second, beyond the design community, what changes might designers advocate for via interactions with e.g., consumers, media, and policymakers?
Application information

Applicants should submit a 3-5 page position paper (including references) in the single-column ACM Master Article Submission Template. Papers can discuss past work, propose future work, raise new ideas, etc. We welcome work from angles such as interaction design, design education, digital wellbeing, privacy and security, law and policy, algorithmic fairness and justice. At least one author of each paper must attend both the workshop and at least one day of the main conference.

All submissions should also include:

  1. A working definition of dark patterns;
  2. An example of a dark pattern from the applicant’s area of interest, preferably in a visual format 1;
  3. At least one way to address dark patterns from within or beyond the design community.

Acceptance will be based on the quality, relevance, and diversity. We hope accepted papers will collectively represent a diverse set of perspectives, domains, and methods.
