Three years ago, Harvard Law professor Lawrence Lessig wrote an essay for The New Republic, "Against Transparency." His argument was an uncommon one: Political transparency is not an unalloyed good. His core argument is well articulated here:
[R]esponses to information are inseparable from their interests, desires, resources, cognitive capacities, and social contexts. Owing to these and other factors, people may ignore information, or misunderstand it, or misuse it. Whether and how new information is used to further public objectives depends upon its incorporation into complex chains of comprehension, action, and response.
I am not a Harvard Law professor, so I will paraphrase the movie Spider-Man (Tobey Maguire version): With great amounts of information comes great opportunity for abuse.
