Heritability: uses and abuses.

This paper begins with a brief summary of the history of the development of ideas in the field of quantitative genetics. Next there is discussion of the controversy surrounding the contention that IQ tests validly estimate some highly heritable general intelligence factor. The validity of the reasoning supporting this contention is questioned.

Logical, epistemological and statistical aspects of nature-nurture data interpretation.

In this paper the nature of the reasoning processes applied to the nature-nurture question is discussed in general and with particular reference to mental and behavioral traits. The nature of data analysis and analysis of variance is discussed. Necessarily, the nature of causation is considered.

A note on goodness of fit of a population to Hardy-Weinberg structure.

The test of goodness of fit of a population to Hardy-Weinberg equilibrium given by Levene [2] and Haldane [1] is valid within a widely accepted recipe for testing goodness of fit of a composite hypothesis. The nature of the result of Cannings and Edwards [3] is described. The result was shown to be quite different than they claimed and, although possible of some interest, not relevant to the testing of goodness of fit to Hardy-Weinberg structure.
