Keller and danah boyd, consolidates conversations and ideas from two years of meetings and discussions and identifies policy changes that would encourage greater engagement and reflection on ethics topics. It also indicates a number of pedagogical needs for data science instructors; explores cultural and institutional barriers to collaboration between ethicists, social scientists and data scientists in academia and industry around ethics challenges; and offers recommendations geared toward those who are invested in a future for data science, big data analytics, and artificial intelligence guided by ethical considerations along with technical merit.
