Firstborn children have higher IQs
THURSDAY, June 21 (HealthDay News) — First-born children possess IQs that are 2.3 points higher, on average, than their younger siblings, a new study contends.
This finding held true even when first-born children didn't survive and a younger child was reared as the eldest, scuttling the idea that genetics determines the difference in IQ among siblings, according to the Norwegian researchers who authored the report, published in the June 22 issue of the journal Science.
"This study really puts to an end a debate that's been going on for more than 70 years," said Frank J. Sulloway, a visiting scholar at the University of California, Berkeley, Institute of Personality and Social Research, and the author of an accompanying commentary in the journal. "The theory of biological differences is pretty much dead as a doornail."
While a 2.3 IQ point difference doesn't seem large, it translates into about a 30 percent increased chance of a child getting into an Ivy League university, Sulloway said.
