The historic data for extended periods of super low interest rate is "sparse" to put it mildly. Pretty much never happened before, so the "consensus view" by economists is not that much of a "consensus" after all. Also, historically a leader of the various Feds does not necessarily have to be an economist - similar how supreme court judges don't necessarily have to have a legal/judge background. Given there is a whole committee of opinions, having some "fresh" outsider views may actually help the discussion. (Though I am not saying that having a former Goverment Sachs fellow necessarily is a poster child of fresh ideas here :)
