What can parents do to stimulate the IQ of their children?

The saved-you-a-click answer: not that much, but do read on.

This week there was the news of the drop of the average IQ aka the reverse Flynn-effect. The big insight of this new study was that this isn’t probably due to genetics, but rather due to the environment. So, if the environment can affect this IQ – besides the obvious genetic element – what can we do as a parent? This new study tries to answer this question by looking at children that were adopted to control for genetic confounding, but the answer is sobering: parenting has a marginal and inconsistent influence on offspring IQ.

So if we combine the insights of both studies we learn:

  • the environment is important related to the Flynn-effect and
  • family and parenting characteristics are not significant contributors to variation in IQ scores.

Well, than we have to look further to education, media, …

Abstract of the study:

The association between family/parenting and offspring IQ remains the matter of debate because of threats related to genetic confounding. The current study is designed to shed some light on this association by examining the influence of parenting influences on adolescent and young adult IQ scores. To do so, a nationally representative sample of youth is analyzed along with a sample of adoptees. The sample of adoptees is able to more fully control for genetic confounding. The results of the study revealed that there is only a marginal and inconsistent influence of parenting on offspring IQ in adolescence and young adulthood. These weak associations were detected in both the nationally representative sample and the adoptee subsample. Sensitivity analyses that focused only on monozygotic twins also revealed no consistent associations between parenting/family measures and verbal intelligence. Taken together, the results of these statistical models indicate that family and parenting characteristics are not significant contributors to variation in IQ scores. The implications of this study are discussed in relation to research examining the effects of family/parenting on offspring IQ scores.
