The only data I have seen relating at all to attitudes, personality traits and sociological description of dispensationalists is here:

"Biblical literalism or low IQ: which came first?"
Razib Kahn got his data on emphasis on literal interpretation of the Bible, by denomination, from here:
Religion, Mobilization, and Social Action - Google Books...
The book is "Religion, Mobilization and Social Action, Anson D. Shupe and others, 1998.
The data On "Membership Growth and Literal Interpretation of the Bible" is on page 57 and in Table 4.2.
The book says the source of this information is The Yearbook of American and Canadian Churches,. Stark, 1994.
For example, of more mainstream denominations, the United Pentecostal
Church had the highest growth rate, 120, and the highest rank in
Biblical Literalism.
Then came The Assemblies of God, with a growth rate of 112, and Biblical Literalism rate of 76,
The Southern Baptists, also now dominated by dispensationalism, had a growth rate of 32 and a Biblical Literal rate of 60.
On the other hand, the United Presbyterians had a Biblical Literal rate
of 28 (low) and a negative growth rate of -17. The Episcopals had a
Biblical Literalism rate of 15 (very low) and a negative growth rate of
-25.
He says he got the IQ scores, apparently by denomination, from the
General Social Survey as reported by The Inductivist. The site,
Indictivist is no longer in existence.
But - the data that Kahn shows has to be viewed within a Biblical perspective.
The non-literal interpretation of scripture by the Episcopals does not
necessarily mean that they have more of the truth or that they have
strong faith. You can use metaphorical or allegorical interpretation
just as well as you can use a consistent literalism to teach another
Gospel - or a luke-warm approach to Jesus Christ, which he spits out of
his mouth (Revelation 3: 15-16.
What is more important for Christians is the interpretation of the finding that denominations which are strongest in teaching a consistent literal view of scripture have
members whose average IQ level is a little lower than denominations who
do not teach a consistent literal view. The interesting thing is not
that the particular denominations that do not teach consistent
literalism have more of the truth and more faith. The interesting thing
is that consistent literalism is used by dispensationalism to promote
its main doctrine - that Old Covenant Israel as supposedly the chosen people based upon heir physical bloodline flesh
are the chosen people. And the denominations that are strongest in
teaching dispensationalism - or consistent literalism - have members
who score a little lower on intelligence tests.
