Oldest Intelligence

Recent research shows that the child rasied as the eldest sibling in a family is likely to have the highest IQ.
A Norwegian team found first born children and those who had lost elder siblings and had hence become the eldest, scored higher on intelligence.
Experts have disagreed for decades about how birth order might influence intellect and achievement.
Supporters of the theory argue the eldest child gets more undivided attention from their parents from an early age.
Others claim differences occur in the womb before birth because with each subsequent pregnancy the mother produces higher levels of antibodies that may attack the foetal brain.
While others claim the relationship between birth order and intelligence is false, being biased by family size - historically, couples with lower IQs have tended to have more children than couples with higher IQs.
Frank Sulloway, of the Institute of Personality and Social Research at the University of California, has been studying how upbringing influences personality and intelligence. He told the Daily Telegraph the higher IQ in the first-born could, in part, be gained by their tutoring of younger siblings.
