Do Rich Parents Matter Round Up?

By: Roshawn Watson

Does parent wealth decide kids ultimate intelligence? There's a loaded question with no easy answer, but a new paper has shed some light on this age-old question.

Many parents will argue that even some of the most basic acts of parenting, such as choice of daycare or time allocated for television, can significantly impact their child's success. Nonetheless, much research examining many different traits (i.e. self-control, intelligence, etc.) suggests that the home environment has a much less profound impact than genes and peer group.
A recent study evaluated the mental ability 750 American twins at 10 months old and then again at 2 years old. The thought was by contrasting differences between fraternal and identical twins, researchers could better understand the impact of genetics and home environment. Also, the babies came from a variety of different socioeconomic statuses (SES), so the influence of wealth and home environment on test scores could be studied as well.

The Results
  • The home environment of 10 months olds was the key determinant of mental ability across every socioeconomic level.
  • However, at 2 years, wealth made a big difference. For 80% of the children from lower SES, their mental ability was still determined by the parents. Genetics had negligible effects.
  • For wealthy 2-year olds, the outcome was starkly different. Genetics accounted for nearly 50% of all differences in mental ability. This determination was made because identical twins performed much more similarly than fraternal twins. Home environment was much less important ("a distant second").
Conclusions From Research
Increases in wealth are inversely correlated with the impact parental choices have on kids' mental ability. That's because "(w)hen you remove the environmental variance, the genetic variance remains." (Razib Kahn) The results also suggests that the genetic potential of 2-year olds may be held back based on the SES of parents. Attempting to eliminate home environment inequalities in early years would not correct for the impact genetic variation has on mental development. I would be interested in longitudinal studies following these kids as they progressed throughout life to see if these same associations persist, and it would also be nice to see if the results of this study are replicated. Perhaps an equally interesting question is what impact does mental ability have on overall success (this is not an indictment on being smart...just food for thought).

Thought Question: What do you think of this research and what kinds of things do you do (or your parents) to give children the edge?
