Are first born smarter?

First hand experience taught me that first born children are indeed advantaged, here is an explanation. Birth order doesn’t affect your personality—just your intelligence | Ars Technica

Quote:
A new study published in PNAS finds that firstborn children tend to score higher on objective measures of intelligence and self-reported measures of intelligence. But it finds that there are no birth-order effects on other personality characteristics.

I'm not yet convinced intelligence is correlated to birth order, (at least with my siblings). This part, about parents limited resources, is interesting. Maybe the child that complains about a sibling being loved more has a point.
Quote:
The predominant social and psychological theory is that parents have more emotional and intellectual resources to give the first child (at least until a second child arrives); this boosts the intelligence of the firstborn.

My older brother is considerably smarter than I am. So that's one in favor of first=smarter.

I say not always the case.

Even if first borns score higher in IQ, perhaps parents pay more attention to the first borns? Nature vs nurture. I can imagine too that first borns are often giving more responsibility, so as a result end up with more accomplishments then the younger ones, well, at least in the eyes of the family.

Third born here, and my tested IQ is much higher than my two older brothers.

Within the margin of error, I would think.

From The Economist:
Quote:
On average, this translated to a difference of 1.5 IQ points between first and second siblings. That figure agrees with the consensus from previous studies, and thus looks confirmed.

Not in my family. The first born has a higher EQ, the second born a higher IQ. But one data point means nothing...

Would not surprise me if IQ and EQ are inversely correlated though?

I agree it's probably in the margin of error...

I'm the youngest and had the highest tested IQ (but fairly close). My younger son scored higher on the Raven Matrices test (what our district uses for GATE testing) than his older brother.

In my siblings case- my brother (middle child) was the best academically - but a mess socially. My sister was the best socially (still is)... and a motivated student. I was a wierdo socially (still am...) and didn't like studying... but could often get good grades with little effort... I'm not sure how predictive the IQ tests are on success....

Of course. And God loves us better too

The Lord said to Moses, 2 Consecrate to me every firstborn male. The first offspring of every womb among the Israelites belongs to me, whether human or animal. Exodus 13:1-2

This also comes with a heavy load of expectation, responsibility, and guilt

You're right, of course. Anecdotes (short accounts of a particular incident or event, especially of an interesting or amusing nature) have nothing to do with data (a series of observations, measurements, or facts; information).

Still, there are many who would disagree.

However, since I've already derailed the topic, I feel I must continue. By chance, I recently came across the origin of the word anecdote. As a linguistic trivia buff, I can't resist sharing it. Normal people should click away from this page now.

Justinian, emperor of the Byzantine Empire from 527 to 565, was one of the few really great emperors. He had a historian, Procopius, in his court who liked to write brief accounts of some of the incidents he observed among the nobility. Some tales were witty and pleasant, but most were indecent or absurd. He never intended them to be published, so he gave them the title "Anecdota", a Greek word meaning "unpublished, kept secret".

On the off chance that anyone is still reading this, you might be interested in my source. It's a delightful book published in 1950. My paperback copy is from 1972. Hundreds of marvelous stories like this about common, everyday words.

Thereby Hangs a Tale - Stories of Curious Word Origins

by Charles Earle Funk (yes, he of Funk & Wagnalls fame).

Thanks, brau. I come to this from the field of medicine, where the almighty randomized controlled trial reigns supreme. That said, anecdotes may be illustrative, and they have human interest.

And yes, I am an Only. I was subjected to an IQ test in grade school. My score was 138.

As the oldest child, I will agree with the premise without even reading the article . Haha.

If there is any statistically significant difference, I think it would be due to the first kid getting more one-on-one time in the early development stages ( I think I spoke to my oldest more than my youngest, because we were the only two people in the house most of the day until baby came along) and the oldest being given more responsibility as the kids get older.

Not in my family. I doubt birth order has anything to do with intelligence. I think alot of it has to do with random luck.
