Recently, I authored a research report at the Center for Democracy & Technology, “This is Transparency to Me”: User Insights into Recommendation Algorithm Reporting, that exemplifies some of the potential benefits of using prototypes in policymaking. We collaborated with people to identify possible recommendations for algorithm transparency reports on social media platforms, and to learn about what information and interfaces would best inform users about how recommendation algorithms work. These prototypes were not suggested solutions, but rather provocations for conversation, an initial step towards understanding what algorithmic transparency reports should include to best support people’s needs.
