Not that Cho, Bobby, or I needed confirmation, but a recent massive study by Norwegian scientists appearing in the journal Science concludes that a child raised as the eldest has a higher intelligence quotient, on average, than younger siblings.
Besides swelling the egos of first borns everywhere, the study states our massive intelligence "appear(s) to be a result of the way the senior child is raised and adapts to the family, not to any special genetic traits that go with being born first..."
"The study is long on numbers and notably short on interpretation. But the bottom line is blunt: the child who holds position as the oldest will possess, on average, an IQ 2.3 points higher than younger siblings. With a sample size of nearly a quarter-million test subjects, that's compelling scientific evidence, according to one specialist."
Like I needed a study to tell me that info.
Secretly, I suspect that Big Fat Worm silently accepted the truth about what our birth orders mean in regard to personality and smarts long ago. He's very sharp actually, but I guess that science has proven me superior once and for all. Also, now that I am coupled with a middle child, I find it fascinating how birth order affects compatibility. And The Polish Princess would insist that any couple take the this test.
