And this is why the United States actually went back to mandatory.
I'd like to ask our other two witnesses this question. There has been a notation that we're going to have a ratio of one to three rather than one to five, but the problem there is the quality of the data, not the volume. I still see some vulnerabilities there.
Also, what are your thoughts about the fact that with the national survey some people--I think--will pick and choose, will cherry-pick it? There will be some questions they are willing to answer and others that they will not be, and I think that's going to require an interesting response in terms of how we statistically deal with that, because it certainly will skew the overall numbers.
But also, even if people pick common things, will that even be statistically meaningful if they're cherry-picking through the national survey? I really think that is what the end result will be. People will fill it out, or a certain amount of it, but they'll get the questions to which they can't be bothered or don't want to actually divulge answers.... That's my concern in this.
