I think that is the question. Certainly we saw the government employees giving the same reaction to each panel report that came out and noting the same types of data. I think what we expected was that if the terms of reference for the first assessments weren't giving you what you wanted, you'd be modifying them as you went progressively through.
It does take time to get better and better information. You'll never have complete information, but I think, unless you change behaviours, you certainly won't get different information.
