Is it possible to ask the survey team for further correlations/regressions?
Yes, we will be adding more results of this sort.  As the results page (and our discussion of results) suggests, within the next month or two we will add data on interquestion correlations and various other effects.  I don't know whether we will release data on three-way interactions among the main questions, but we'll see.  We will eventually release a near-full data set to a limited number of researchers who want to perform studies using it, but that won't be for a while yet.

In the meantime, if people would like to see certain sorts of data released, feel free to put in a request here.
