When measures of individual differences are used to predict group performance, the reporting of correlations computed on samples of individuals invites misinterpretation and dismissal of the data. In contrast, if regression equations, in which the correlations required are computed on bivariate means, as are the distribution statistics, it is difficult to underappreciate or lightly dismiss the utility of psychological predictors. Given sufficient sample size and linearity of regression, this… Expand

What Can Cross-Cultural Correlations Teach Us about Human Nature?
TLDR
This work provides examples of how cross-cultural non-equivalence of measurement gives rise to problems in the context of testing evolutionary hypotheses about human behavior, and offers some suggestions for future research. Expand
Comments on correlations of IQ with skin color and geographic–demographic variables
Abstract A large number of national and geographic population samples were used to test the hypothesis that the variation in mean values of skin color in the diverse populations are consistentlyExpand

Differential epidemiology: IQ, neuroticism, and chronic disease by the 50 U.S. states
Abstract Current research shows that geo-political units (e.g., the 50 U.S. states) vary meaningfully on psychological dimensions like intelligence (IQ) and neuroticism (N). A new scientificExpand
Lynn's r/k selection theory of criminality revisited: Consideration of individual differences and developmental life history contributions to the patterning of population differences in antagonistic social strategies.
We revisit an old theory proposed by Lynn, connecting race differences in criminality and psychopathy with r/k selection. The origin of this group-difference is attributed to cold-selection in theExpand

Partial Information Framework: Basic Theory and Applications
TLDR
This dissertation shows that measurement error is not appropriate for modeling forecast heterogeneity and then introduces information diversity as a more appropriate yet fundamentally different alternative and the Gaussian partial information model, a very close yet practical specification of the framework.
