This project would not have been possible without the stimulating conversations we’ve had with the Assembly Cohort and Assembly Advisors. We are especially indebted to Shira Chung for designing the AI Blindspot cards, Lara Taber for designing the AI Blindspot logo, and Mariel Calderon for designing the AI Blindspot Discovery Process. We are grateful to Friederike Schuur, Walter Frick, and Erich Ludwig for insightful conversations provided in user feedback sessions, as well as John Bowers for his peerless edits. Finally, we want to thank Hilary Ross for her unwavering support and guidance during the Assembly program.


The AI Blindspot cards were developed by Ania Calderon, Dan Taber, Hong Qu, and Jeff Wen during the Berkman Klein Center Assembly program.
