Heterosis doesn't cause the Flynn effect: A critical examination of Mingroni (2007).

Abstract in latest Psychological Review.  See link below for more info.

Mingroni (see record 2007-10421-011) proposed that heterosis or hybrid vigor may be the principal driver of the Flynn effect—the tendency for IQ scores to increase at a rate of approximately 3 points per decade. This model was presented as a resolution to the IQ paradox—the observation that IQ scores have been increasing despite their high adult heritability—on the basis that substantial changes in IQ can only be accounted for by changes in underlying genetic factors. It is here argued that this model is predicated upon a misconception of the Flynn effect, which is most pronounced on the least g-loaded components of cognitive ability tests and is uncorrelated with genetic effects such as inbreeding depression scores (which are correlated with the g loadings of tests). Evidence supportive of the recently proposed life history model of the Flynn effect is presented. In the discussion, other theoretical objections to the heterosis model are also considered. On this basis, it is concluded that the Flynn effect is strongly entwined with developmental status and that heterosis cannot be its principal cause.

Research byte: Temporal stability of general intelligence (g)

The following article is an excellent synthesis of research on the stability of general intelligence over time as well as the consistency (vs. temporal degradation) of g's prediction of academic and occupational outcomes over time.

The general findings are that general intelligence is remarkably stable over long periods of time. However, and this is important in n=1 individual cases, strong group stability statistics do not necessarily translate to IQ scores being near identical across time for individuals. The authors conclusion about decision validity is particularly important when evaluating Dx decisions for individuals across time (across IQ scores from different times in a person's life).
