If one gets to chose the questions and assemble the questionnaire then
shown to all study participants, I would submit that more or less arbitrary
study results can be generated by, consciously or subconsciously, picking
the "right" questions. Curiously, the two people that "reviewed" the
questions here were "a Wikipedia editor and administrator," and a
"long-term volunteer editor and administrator of Wikipedia" and "founder
of
[...] the Wiki Project Med Foundation."
Not being negative or anything, but if you're trying to scientifically
evaluate whether a given exam prep book improves students' grades, would
you let the editors of the book prepare the test exam?
