The relationship between populism and transparency is more complex than it first appears. Populists claim to support and even embody transparency as part of their claims to communicate directly and authentically with the public. Yet at the same time, they attack, corrupt, and misuse their legal obligations to report and disclose. Populism and Transparency is the first comprehensive effort to unpack the tactics populists employ to weaken transparency institutions, how the public responds to their efforts, and the short and long-term consequences of populist confrontations with transparency, both within and outside of government. Spanning four continents and drawing from multiple disciplines, the book documents how populists' fundamental tensions with the administrative norms of transparency fuel the anti-democratic transparency backsliding with the potential for lasting harm to foundational accountability principles.
