Big data has produced big change. As anyone with a phone knows, technology has exploded – and created startling amounts of data about our lives. How is this information tracked and stored, and how does that affect our rights? Algorithms trained on big data have transformed law enforcement and social services. Cash-strapped governments have proven especially eager to use automated tools. Some claim to predict crime “hot spots” and even individuals at risk. Others recommend whether to detain or release defendants before trial. And some assign children to schools and families to shelters. All these automated computing tools today play a larger role than ever before.

Fans praise these as better than fallible human judgment. But do they live up to their promise? How to judge claims by the companies who stand to make money off them? Can we really achieve transparency and efficiency? Do big data tools, as some charge, simply reinforce class and race prejudice under the guise of objectivity? Can these systems be harnessed for good? And how can affected communities gain control over how data is used and packaged?

Join us for a discussion on the use of big data in social welfare, policing, and criminal justice, and its impact on marginalized communities.

With social media on the rise, living standards stagnating, and fears of multiethnic democracy growing, voters are discontent with politics. Across the world — from India to Turkey to the United States — authoritarian populists have seized power. In his new book, Yascha Mounk examines how trust in the political system is dwindling as money in politics soars and democracy wanes. How did we get here, and how can we protect democracy moving forward?

Yascha Mounk, Lecturer on Political Theory at Harvard University and author of the new book The People vs. Democracy: Why Our Freedom Is in Danger and How to Save It,discusses the future of democracy with Wendy Weiser, Director of the Democracy Program and the Brennan Center for Justice.
