I think this is kind of interesting, but I don't totally understand why, even if they lost an older sibling, the second-youngest sibling gains some IQ points. They might be considered the oldest sibling now, but they weren't born first.

I agree with Esther. I was like what?? when I first saw this. I thought it might be interesting.

I thought that this article was very interesting. I think that older siblings might have higher IQs because since they were the first born, the parents only had to take care of that one child, but when the second sibling is born, the parents have to take care of both kids, so the second born child doesn't get as much attention as the first born did. This might especially impact the child because babies require so much attention. For example, I was the second born out of three kids, and my parents didn't read to my little sister nearly as much as they did to my older brother and I. I'm not sure if that impacted her, but she learned to read at an older age than my brother and I did. However that theory doesn't make sense as to why the younger siblings start out with higher IQs, and then later in life the older siblings have higher IQs.

This is an amazing article, but I don't see how a second-born child can become smarter by their older sibling dying. Morbid...
Well, anyways, this was a very interesting post, and all I have to say is "Ha ha ha Marcus!"

I love this article, especially because I am the older sibling. I also think it is so weird that if the first born dies, the second gets smarter. I wonder if its because of attention. This article my not be very accurate because they only tested on Norwegian brothers. I wonder if it is different for sisters and a sister and brother. Older siblings may be smarter because of the old tradition of caring more for you first than your second child. This theory could be false for other ethnics. Another reason could be because of family time. With me, my parents had a lot of time to teach me, but now they are very busy and can't give as much attention to my brother.

I don't think this article is very accurate. I think that if the both children were treated like first borns, then they would be equally bright. Me and my sister are separated and though my IQ is already much higher than hers (not trying to sound conceited) I think she would be making the same amount of progress of a normal first born. Also, what if the parents each liked a different child? Then wouldn't they be treated as a first born by each and be equally brilliant? Also I disagree with the fact that younger siblings are smarter, wouldn't the older sibling make fun of the younger sibling and thus be detrimental to the younger's learning. Eh! I love this article though there are many possible sources of error.

This article is so interesting. I think it's so cool that older siblings have a higher IQ then younger ones. I am not sure how it works, but it's awesome. The part that I thought was really cool was that if the older one dies then the younger one gets smarter. That's so amazing to me. I think it might have something to do with the attention given to the older one, but I really don't know.

I am mad because I have an older brother, so is that saying that he's smarter than me? I don't know. I think that if you are the second born you have to learn skills about cooperation that the first born does for the first few years. I'm not sure if "diluting the intellectual environment" is good or not. It says that every child dilutes the intellectual environment. I don't think this is good. My brother helps me with my homework sometimes and I think they said this was good.

I don't think this is entirely true, but I can't be sure. My grades are pretty much the same as my older sister's, but they did say the younger sibling has the same or higher IQ up until about 12 years old- I'm 11, my sister is 13. I don't understand how the older sibling can have a higher IQ. I looked at the article and it was published in 2007, so scientific thoughts might have changed since then.

Anthony said...

I feel bad for the youngest child! When I saw this article I was also thinking like many other kids said why would a younger child gain intelligence from their older sibling passing away? But also, this article ONLY tests Norwegian kids, not American or Chinese, or even South African. So I'm starting to think that this article might not be that accurate. Also, as Emma said, I think this also has something to do with attention because if you are a first born, for a couple of years, you get all the attention. I liked this article, but I can't relate to it because I am an only child.

I completely agree with what Esther said. I got really confused...

Sinclaire said...

I wonder if siblings live in different places, they will have closer to the same IQ. I also wonder if people raise their children differently, they will grow up to have different IQs. This was a very interesting article and I enjoyed it a lot. (being the older sibling!)

Luca  said...

Yes, I agree with Esther, but I also sort of understand it. The whole "becoming a firstborn through death of siblings" thing is confusing, but I hope Marcus doesn't read this. I'm scared for my health.
