[Editor's note: Dr. Rushton was asked by the editor to supply a list comprising only his own works, while Dr. Allen was asked to cite a broader range of writings.]

I read with interest the Opinion articles by Professors Rushton and Allen, dealing with Rushton's work on race-related research. I have had some interest in this topic myself, having taught a course on "The Social Issues in Genetics" for several years, and the I.Q./race issue was always hotly debated in this course. I share many of Allen's concerns about the weaknesses of much of the research in this area, most specifically the lack of adequate control of the environment.

Further, an argument that Allen didn't specifically advance is also crucial - namely that the heredity/environment interaction is so fundamental that if one changed environments sufficiently, any given finding could completely flip-flop with the relationship now in the opposite direction.
