TL;DR: A growing body of empirical literature supports the validity of psychometric assessments of human life history strategies, but no comprehensive quantitative summaries have yet been published as mentioned in this paper, but a meta-analytic validation study of a 20-item Short-Form of the Arizona Life History Battery (ALHB), the Mini-K, using metaanalytic procedures to survey a multiplicity of published and unpublished studies on English-speaking North American college student samples.

TL;DR: This response is organized into four main sections: a review of psychometric methods for the assessment of human LH strategy, expounding upon the essence of the approach, theoretical/conceptual concerns regarding the critique, and recommendations for future research that might be helpful in closing the gap between the psychometric and biometric approaches to measurement in this area.

TL;DR: Using meta-analytic databases of ethological observations of cognitive abilities involving 69 primate species, it is found that cognitive abilities that load more strongly on a common factor (which is here termed G) are associated with significantly bigger interspecies differences and bigger inter species variance.

TL;DR: This paper found that the more g-loaded cognitive abilities would also be more heritable in addition to presenting greater additive genetic variance and interindividual phenotypic variability, consistent with previous findings from comparative primate studies indicating that it is associated with high interspecies variance and has evolved rapidly.

TL;DR: It has been theorized that declines in general intelligence (g) due to genetic selection stemming from the inverse association between completed fertility and IQ and the Flynn effect co-occur, with the effects of the latter being concentrated on less heritable non-g sources of intelligence variance.
