This article presents the author's response to Robert Maranto's review of "Bad Students, Not Bad Schools". The author begins by thanking Professor Maranto for his thoughtful review of his "Bad Students, Not Bad Schools" (2010). Professor Maranto is the first professional educator to acknowledge the book's existence, a fact that says much about today's intellectual climate. The author discusses certain issues beginning with the Mother of All Unspeakable realities: group differences in IQ. All people can agree that groups vary in average IQs, and IQs powerfully influences academic performance. "Bad Students" stresses this point, or at least as much as possible in the politically correct times. Professor Maranto does not dispute this awkward reality but insists that groups do change average IQs and this gives educators hope that slower kids, with the right pedagogy and effort, can be brought up to speed. The author disagrees and explains what social scientists call the units of analysis problem.
