"The study of race differences in intelligence is an acid test case for psychology. Can behavioral scientists research this subject with the same freedom, objectivity, thoroughness, and scientific integrity with which they go about investigating other psychological phenomena? In short, can psychology be scientific when it confronts an issue that is steeped in social ideologies? In my attempts at self- analysis this question seems to me to be one of the most basic motivating elements in my involvement with research on the nature of the observed psychological differences among racial groups. In a recent article (Jensen, 1985b) I stated:I make no apology for my choice of research topics. I think that my own nominal fields of expertise (educational and differential psychology) would be remiss if they shunned efforts to describe and understand more accurately one of the most perplexing and critical of current problems. Of all the myriad subjects being investigated in the behavioral and social sciences, it seems to me that one of the most easily justified is the black- white statistical disparity in cognitive abilities, with its far reaching educational, economic, and social consequences. Should we not apply the tools of our science to such socially important issues as best we can? The success of such efforts will demonstrate that psychology can actually behave as a science in dealing with socially sensitive issues, rather than merely rationalize popular prejudice and social ideology.
