Yes, these resources (studies conducted by the University of Iowa on the subject of acceleration, A Nation Deceived, and the new report A Nation Empowered) are frequently mentioned on the forums.

Rather than the existence of researched studies quelling discussion and answering poster's questions, the sharing of those resources seem to spark additional interest in discussing how the personal experiences of current forum members compare with researched studies... as both research and anecdotal evidence are valued by forum members.
