Few would disagree that more transparency is generally a good thing for democracy. Indeed so few would disagree that an unthinking consensus has developed where transparency appears to have become the political tonic to cure all ills. Political unaccountability? Let's have more transparency. Economic inefficiency? More transparency. Too close a relationship between politicians and the press? We need more transparency. These six essays by Andrew Murray, John Lloyd, Helen Margetts, Sean Maguire, Aleks Krotosky and Kevin Marsh question the sometimes unthinking consensus about the benefits of transparency. They question it from a legal perspective, from a journalistic perspective, from a governance perspective, from a technological perspective, from practical perspective, and from a civic perspective.
