The problem of hierarchial thought in the work of Arthur Jensen

Policy Implications of the IQ Controversy

Jesness' analysis of the Preston data offers no support for the utilization of Interpersonal Maturity Level Theory (I-Level Theory) to reduce parole violation among delinquents. The data are reanalysed here and show interaction effects between I-Level and Treatment for a specially selected Psychiatric Treatment Unit. There are no interaction effects for other groups of subjects. The characteristics on which the Psychiatric unit was selected do not appear to account for the results. Instead, there is evidence that treatment strategies were better developed in this unit. Findings on interaction effects in the Psychiatric Unit are favorable to the emphasis on differential treatment in California's Community Treatment Project and to some of the Project's treatment recommendations. Support for the use of the I-Level typology appears to have been limited, at least in part, by insufficient empirical testing of interaction effects, poor interpretation of findings, and conclusions drawn from inappropriate data.

Differential Treatment in an Institution: Reexamining the Preston Study

Social bias in mental testing

This essay uses rhetorical analysis to defend the population geneticist Richard Lewontin from accusations made by E. O. Wilson and others that his Marxist social philosophy distorts his empirical science. I suggest that Lewontin’s appeal to his own authority as an experimental evolutionary biologist supports his claim that racism has no biological justification and that it is his opponents whose assumptions about society distort their scientific arguments.
