Silver bells are ringing across Britain as the nation celebrates the discovery of its lil’est genius. Two year old Karina Oakley has scored a 160 on the Stanford-Binet IQ test, administered to her by the professor her mother hired.

An IQ scored of 160 places little Karina on the lower edge of the “exceptionally gifted” intelligence classification. The high IQ society Mensa only requires an IQ score of 132 to enter, so Karina’s evaluation places her solidly in the ranks of such official geniuses as Cutthroat Island star and V8 juice fan, Geena Davis, as well as Playboy Playmate Julie Peterson and General “Stormin’ Norman” Schwarzkopf.

Despite all of the “Raising Your Gifted Child”-type books that are no doubt currently filling the padded horizontal surfaces of the Oakley household, raising this little genius will be difficult work. This is surely why Karina’s mother allowed the story to be printed in the respected British periodical The Daily Telegraph; she’s looking for support. So let’s help out.

What does an IQ of 160 really mean? Beyond “exceptionally gifted” or “Geena Davis-smart,” I mean. Let’s explore. For Karina’s sake.

The Stanford-Binet test administered to Karina had its beginnings more than a hundred years ago, when the French psychologist Alfred Binet and his colleague Theodore Simon were studying mental disabilities in school children. They devised a test of increasingly difficult questions and activities (ranging from touching one’s own nose to explaining abstract concepts) and determined the age at which a typical child could answer or perform them correctly. How well a kid tested would determine his or her “mental age,” or their level of development relative to others. But even a hundred years ago, Binet cautioned that the results of these tests should not be interpreted literally, because there’s a margin of error inherent in such testing, and because intelligence is plastic, or changeable, anyway.

Ten years later, researchers at Stanford University expanded on the Binet-Simon test, removing some items, and adding some new ones. The resulting Stanford-Binet test has been revised several times, and it’s now one of the standard IQ or “intelligence quotient” tests. The “mental age” concept from the original test, however, is still the key idea. It’s basically the same concept as an “intelligence quotient”—both are measurements of an individual’s intelligence (or mental age) compared to a standard or average intelligence.

So an IQ score near 100 is about average. That doesn’t mean that if you have an IQ of 100 you’re just okay, while most people might be smarter than you. Necessarily, most people should fall right around 100. With IQ tests, what you end up knowing is whether you test below, about the same, or above most people.

Now, little 2-year-old Karina has an IQ of 160. Does that mean she’s tossing around quantum mechanical problems, fixing the refrigerator, and deconstructing Proust in her spare time? Probably not. The test is going to be relative to her group; two-year-olds. So most of Karina’s colleagues will have an IQ of about 100, but Karina herself, well, she’s notably more intelligent than most two-year-olds. But, then again, so is my golden retriever.

It seems like administering an IQ test to a tiny kid like that is kind of silly. Their weird child-brains are all growing and developing, and all at different rates (which is normal). So does this just mean that Karina is as smart as a 3-year-old? The dog certainly aspires to that.

Karina will probably continue to be a clever little dude for the rest of her life, but what’s important is that she now has an official test, taken when she had been alive for just two years, to prove it. That test will be like the North Star, guiding her through life, and, like the star, perhaps just out of reach. It will be the trump card in shrill arguments with school councilors. And it will, above all else, make Karina friends, especially if she’s placed in a gifted and talented program early in her education. It’s the first stepping-stone on a glorious path to a nervous breakdown as a 16-year-old college freshman. Cheers, Mr. and Mrs. Oakley.

PS— Really, what it boils down to is that I’m insanely jealous of this little girl.

PPS—A fun little bonus story regarding child geniuses:
My young cousin: The doctor tested me to see how smart I am. He said I’m a genie!
My brother: You mean “genius.”

One of the random questions we often get at the Science Buzz is “why is the sky blue?”. A recent article published by the Columbia News Service addresses this question, along with nine others, in an article called How High is Your Science IQ? The article is a list of ten science facts every high school graduate should know. To get to the 10 facts the Columbia News Service asked Nobel Prize winners, institute heads, and teachers, “What is one science question every high school graduate should be able to answer?” The questions are good ones – how many can you get right? Check out the article and test yourself!

Oh, and if you want even more information on why the sky is blue, here is a good Wikipedia article on the subject.
