Arthur Jensen: Research

“I will be ashamed the day I feel I should knuckle under to social-political pressures about issues and research I think are important for the advance of scientific knowledge.”

Context: [Interview: Responding to a question about whether it was smart to publish his 1969 article at the time he did] In retrospect, however, I would hope that I would not have changed a thing in that article, even if I had been able to imagine the supposed "storm" it caused. I will be ashamed the day I feel I should knuckle under to social-political pressures about issues and research I think are important for the advance of scientific knowledge.

“It was little consolation that I had been ‘in good company’ in my ignorance of genetics; in fact, that aspect of the situation seemed even more alarming to me. I was overwhelmed by the realization of the almost Herculean job that would be needed to get the majority of psychologists and educators fully to recognize the importance of genetics for the understanding of variation in psychological traits. Hence, rather than attempting at first to add small increments of original empirical research to the body of knowledge on the genetics of human abilities, I thought my most useful role at that point was a primarily didactic one.”

“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.”

“Given the present state of our knowledge, and insufficient thought on my part, my own prescription for the time being is to deal as best we can with individual differences and let the statistical group differences fall where they may. Society’s general concern with race and other social group differences is not the product of research on these matters, but arises from chauvinist-like attitudes of racial group identity and solidarity in connection with political power and economic interest. It might be termed meta-racism. The ‘race problem’ from that viewpoint is lower in my own hierarchy of values than concern with individual justice and alleviation of individual misfortune. Though it would be blind not to acknowledge the reality of certain statistical differences among populations, I would find it difficult to be the least concerned with any given individual’s racial heritage. Perhaps I may be too insensitive on this score, never having felt much sense of racial identity myself.”

“The comments on value-free psychology are so vague as to have no teeth. I wish Sternberg had delivered on whatever point he was trying to make by pointing to some actual examples of how my values (or their lack) have led me to ‘comparisons that should not be made’ or inferences predicated on untrue assumptions. The ‘value-free’ psychology I would advocate is not free of scientific values, or humanistic moral values, or the value of social responsibility, but I do decry the infestation of psychology, or any science, by political and social ideologies. Ideological contamination of psychological research can only make suspect the claim of psychology to scientific status.”

Science

“The fact that a reasonable hypothesis has not been rigorously proved does not mean that it should be summarily dismissed. It only means that we need more appropriate research for putting it to the test. I believe such definitive research is entirely possible but has not yet been done. So all we are left with are various lines of evidence, no one of which is definitive alone, but which, viewed all together, make it a not unreasonable hypothesis that genetic factors are strongly implicated in the average Negro-white intelligence difference. The preponderance of the evidence is, in my opinion, less consistent with a strictly environmental hypothesis than with a genetic hypothesis, which, of course, does not exclude the influence of environment or its interaction with genetic factors.”
