Waldron is one of my favorite contemporary philosophers, here is one bit from his NYRoB essay:
More reassuring, I think, would be a candid assessment of what might go wrong with nudging. One of Sunstein’s many books (from before his time in the White House) is entitled Worst-Case Scenarios. Could we please have something like that as a companion to Nudge?
I am afraid there is very little awareness in these books about the problem of trust. Every day we are bombarded with offers whose choice architecture is manipulated, not necessarily in our favor. The latest deal from the phone company is designed to bamboozle us, and we may well want such blandishments regulated. But it is not clear whether the regulators themselves are trustworthy. Governments don’t just make mistakes; they sometimes set out deliberately to mislead us. The mendacity of elected officials is legendary and claims on our trust and credulity have often been squandered. It is against this background that we have to consider how nudging might be abused.
