Nottingham,
The lack of a "don't know" is my biggest problem with it. I had this discussion with people at Uni doing socialogy and pyschology and behavioural science type courses and have been on a couple of related things and seen a couple of related exhibits at museums.
Setting the right questions is actually really difficult.
And by deliberately phrasing questions and response in multiple choice you can easily bias the results whether you meant to or not.
I can't remember any links to them but there's a really amusing "Heavy boots" story, don't know how true it is I might have it in email and I post it, and an equally amusing email that I don't have on someone getting a large majority of americans to agree that a ban on Di-Hydrogen-Monoxide would be a good thing.
