I've been trying to think of a "fair" question, but I'm having a hard time.
It really seems to be the kind of topic that requires more sustained
dialogue than an opinion survey permits.
I haven't personally worked with Zogby and I'm not aware of them doing the
kinds of surveys we would use in a court case. It certainly is a "brand
name" in public opinion polls often quoted in popular media, but that
doesn't mean anything.

Welcome to the list David.
Your insight to the pitfalls of polling is very helpful, but I wonder if
you could give an example of a question roughly corresponding to the one
you criticized below that would be relatively immune to the difficulties
you noted. It seems to me that any set of questions pertaining to evolution
simple enough to be posed to and answered by the general public would be
subject to such problems.
Of course, this probably just means that polling is not the best way to
address this issue.
Also, what is your general take on Zogby as an organization? What is its
professional status? Is it well resepected?

Hello. I'm new to this list and am finding the discussion of the Zogby
survey results interesting. By way of brief background to my following
comment, I'm a law professor and previously I was a litigation attorney
12 years. Surveys are often introduced as evidence in court proceedings,
particularly in my area of expertise, intellectual property. For example,
in a trademark infringement case, surveys are often used to determine
whether the consumer public perceives the defendant's mark to be
confusingly similar to the plaintiff's mark. One of the key evidentiary
principles for determining the weight to attribute to a given survey is
whether the survey employed leading questions or questions that make
questionable assumptions. This survey would be easy to attack on that
basis. To highlight one example:

Part B of this question assumes there is "scientific evidence against"
Darwin's theory of evolution. Behind that assumption, as has previously
been pointed out, is an assumption about what is meant by "Darwin's theory
of evolution." Also behind that intial assumption is, presumably, an
assumption about what is meant by "scientific evidence," and that,
"scientific evidence" means, there is some such evidence "against"
theory. We could have expert witnesses on the stand for days testifying
about those assumptions alone.
The really difficult and interesting thing from a public policy
is how it would be possible to craft a fair and balanced (to use a phrase
that has been much bandied about lately) survey when much of the public
generally lacks any understanding that terms such as "scientific evidence"
are loaded. I'd hate to see public policy made based on this Zogby
but I'd also hate to see public dollars spent on public education without
accounting for public opinion at all.
