We'll be joined by Renee DiResta, until recentaly, the technical research manager at Stanford Internet Observatory, a cross-disciplinary program of research, teaching and policy engagement for the study of adversarial abuse in current information technologies. She is the author of the new book, Invisible Rulers: The People Who Turn Lies into Reality (If you make it trend, you make it true.)

From the book jacket: "Power and influence have been profoundly transformed. A virtual rumor mill of niche propogandists increasingly shapes public opinion. Positioning themselves as trustworthy Davids, their reach, influence, and economics make them invisible rulers who create bespoke realities to revolutionize politics, culture, and society. Democratic validity, scientific proof, and leaders can be bulldozed. What to do? - while these propogandists bear no responsibility for the consequences, there are ways to rapidly adapt and fight back."
