The test methods available will depend on the sample space. Predispostions
can be factored out mathematically after the data are gathered--no need to
do before and afters--in fact that will bias the results of those who
might find or invent some reason to believe which group they are in.
And here's an important point: if we do generate enough interest to do
something, and get a good sample base, we should STOP TALKING about the
possible protocols of the experiment in public. Those who will be out
of the sample set--the experimenters, helpers, data collectors, and
advisors--should discuss the protocol among themselves privately where
the subjects can't hear, so they won't have any expectations.
