Chairman clarifies surprise is not objective; Fed focused on making best decisions, not managing expectations.

Following up on that, there was more uncertainty in the markets about what the Fed would do at this meeting. To some extent you might think that's what you want to see. But my question is about is there a point at which you would not want to surprise the markets if they were pricing in something with higher certainty that was opposite of what you were intending to do, what are the risks that you see associated with that? Yes, so it's a good question. Surprise is not the objective function. Surprise is not what we're solving for. We have a clear North Star, what we're solving for is how to make the best decisions. Almost everything else should be in service to that goal.
