I do worry that the longer this continues, the lower the response rate we'll get. We have been reasonably successful without enforcing fines, and there has never been prison. People feel it's a duty to fill this out, and whether they want to or not they do it and off it goes; they don't deliberate on it a lot.
I do worry that we can create a sense that, “You know what? You don't really need to fill this out. It's not that important.” Again, I don't really care if that brings the overall response rate down, but it may do it in a differentiated fashion, of course--people in different socio-economic conditions.
