I don't know about Chris,Mike,Stephen,Bill,John,Scott,Peter,Paul, and
Mary, but I think most labs run pilot studies...it's just not called
that.
Nor is it especially demarcated with the PI proclaiming...
Very well,beginthe
Pilot Study!
Rather, one takes a boo at the data for the first few subjects and see
if it's generally in line with expectations of the hypothesis.
This has the generally beneficial effect of reminding hier scientist
to plug in the recording device before subjecting the paid subject
(often nowadays, potentially paid millions might be a better
statement) to 2 hours of a learning protocol !

I could bet that Chris,Mike,Stephen,Paul,Bill,John,and Scott(the
-out-of-office reply dude) never run a pilot study but there was a time
when advisors and research supervisors would always recommend to run a
pilot before undertaking some research,thesis,or dissertation.As a matter
of fact Murray Sidman in a work titled Tactics in Scientific Research seemed
to have recommended doing pilot studies.Although there are many reasons
given to running a pilot,such as methodologicaland other issues,it does
appear that the procedure was frowned upon.
I think that the major criticism was that a pilot study was still a valid
experiment-so in some sense one was performing two experiments.The other
criticism was probably philosophical: entering research with preliminary
projected results is really not cool from a scientific perspective.
One thing I would say about the animal pilot studies-it tells us which
animals are likely
to die and that is a no no for statistical analysis.Just curious what would
have happened if Milgram and Rosenhan(Tipsters' favorite punching bag) had
run a pilot.
In a theoretical psychology state of mind.
