This can only be someone that has no doubts whatsoever. Pity he lives in another (non parallel) universe:

Much of what Plosser had to say about the economic outlook was positive, and while he supports the enhanced disclosure of Fed monetary policy views, he is concerned that conditional commitments made by the central bank are instead being viewed as hard-and-fast pledges. What’s more, Plosser worries the large amount of stimulus delivered by the Fed could be a problem in the future. “Given the very accommodative monetary policy that has been in place for more than three years, I believe we must continue to monitor inflation measures very carefully,” he said.

What would he say of pictures such as these?
