I don't know of any metric by which you're going to do it. Pollsters are routinely getting everything wrong, so I don't think they're the answer. I would say, though, that there is a concern. If there have been spectacular, publicly renowned instances of problems with the agencies, I think our assumption has to be that there's going to be some erosion.
I should also say that this committee's role isn't only that. They also have a value-added role to the agencies themselves, but the knock-on effect is, I think, to provide public confidence. Maybe that's a better word than “restore”.
