It is very strange that you invite me to tell you a reference for an
article and simultaneously you write that you don't care how scientific
journals define IIAC. However, here is a reference:

   Prasanta K. Pattanaik, Bezalel Peleg, "Distribution of Power Under
   Stochastic Social Choice Rules," Econometrica, vol. 54, p. 909-921,
   1986.

Feel free to read this article.

Who is "some"? Could you please tell me a reference for an article
(1) that says that plurality passes Condorcet or (2) that says that
Condorcet may be applied only to rank methods to keed plurality from
passing?
