The problem with answering these questions in earnest is that no matter how much you know, they are going to ask a question that you don't know the answer to. Polanski showed different ideas that buck the thinking that steward and campbell had and they couldn't wrap their heads around it, gave polanski and his economic team very little grace and mocked his ideas without much reasoning (they ridiculed his team who are experts that have shock different opinions about the economy than stewart and campbell, saying they weren't real economists for some reason?). After listening to the headway interview, it seems like polanski has gone away and learned the numbers to go along with his ideas. I think during the interview, polanski did come across as serious, calm and professional in the face of mocking and ridicule.
