The study gives a few reasons for the oldest child being the smartest, and they do make sense. For one, the older children obviously get more undivided attention.
The study didn't cover whether the lack of undivided attention for a younger child made him or her more likely to be a problem child.
The study also noted that older children are usually expected to teach their younger siblings some of the knowledge and skills they've picked up.
So maybe it's no wonder that Daniel, Billy, and Stephen followed in Alec's footsteps.
Now, the study put the difference in IQ between the older and younger siblings at 1.5 points — not exactly an Earth-shattering number. And it goes down by that much per sibling.
If the study is indeed correct, although Julia has the hardware, Eric — her senior by 10 years — likely did better on his SATs. But probably only barely.
The researchers behind the study estimated that, in a two-child family, the older child had a six-in-10 chance of having a higher IQ.
Which does leave a four-in-10 probability that the older child won't be smarter, or that they'll be just as smart. The older child might, however, perceive themselves as more intelligent.
