“Why debate the value in having a gold coin when there is doubt over whether it's gold or not?
“Of course scientifically and carefully conducted surveys are useful but they are extremely difficult to manage in practice even for companies that specialise in the field. Of course I know what the value in good information is but again, this is not relevant to the discussion.
“The debate is not about whether a good survey is useful or not, but whether the actual survey that we're talking about constitutes a good survey or not and is thus of any value beyond mere entertainment and opinion reinforcement purposes (or 'propaganda').
“Most 'good' surveys can say what their margin of error is and why and also what the demographic of their sample was and why. Without such things how are we to know whether it is good or not? Are we to just assume?
“Couldn't anyone claim anything they wanted in a survey unless there were clear and sound methods behind it?”
Simon,
I asked: Do you know for WHAT and HOW such a survey collection is useful, or not?
What you write above says, in other words, no.
1. I’ve not spoken to what value—gold or not-gold—a survey can have. I’ve asserted that even bad information can provide for a useful survey if that information is collected consistently and at consistent intervals.
2. I don’t understand what you mean by “scientific and carefully conducted” except that surveys with consistent means and methods, and conducted at consistent intervals are sufficient to yield useful information.
3. If Cedar’s survey contains data collected consistently in means and methods, and was collected at consistent intervals then it’s useful. Apparently you don’t know why.
4. “Claiming anything” is not a survey of data collected consistently in means and methods and collected at consistent intervals.
You’re not talking about what I’m talking about.
Worse, you’ve taken time to characterize me based on a demonstrably inept perspective of what I’ve actually written.
So what are you talking about?
