This proposal isn't really about the merits of any particular study.  I
only offered a link to the discussions about my most recent user study
because I felt it was a good example of push-back from Wikipedia editors.

For a better view of the *initial* troubles with the first failed study,
see Katherine's talk page
http://en.wikipedia.org/wiki/User_talk:KatherinePanciera.  I'm most
concerned about what happen in that study. After Katherine asked for
Wikipedia users to participate simply by taking a survey, her account
was nominated for deletion for allegedly violating an obscure policy
that did not match he actions.  Katherine had no policy to cite in order
to defend herself.  For simply asking people to participate in a survey,
her account was nearly banned.

I'd suggest you have a read through the proposal (it is actually quite
small) in order to more clearly understand the problem we wish to
solve.  The first section is devoted to just that.
