IQ is obviously real and measurable, at least accurately enough to find people who score higher than one in ten thousand, maybe more. This is undeniable: we can identify the million people on the planet who have a higher IQ than the rest, if we want to.
It is also true that IQ is a component of what we call intelligence, which happens to be the easiest to measure. IQ is measured via puzzles and logical reasoning. This means that people who score high on these tests are very good at those things. Good enough, in some cases, to be math or physics luminaries because that is primarily what those disciplines are about: solving novel puzzles via hard reasoning.
But what we call intelligence is more than that. IQ doesn't measure creativity, resourcefulness, curiosity, persistence. There are people with high IQs who lack one or more of those things. They might be great at the NYT Spelling Bee, but they work at a grocery store. They might be incapable of coming up with novel insights about how the world works, because that requires being interested and curious.
The smartest people you will meet will have a sufficiently high IQ, and also many of the above attributes that are harder to measure. And you will also meet people who do really well in life despite not having high IQs, particularly in professions for which a high IQ is not particularly useful. Or even detrimental (see posts here by typical politicians, who often don't even attempt logical reasoning).
So: IQ is real, useful, correlated with success, and you want to have the highest IQ possible. Yes, there is much more to genius than IQ, and there is much more to success in life than IQ.
Gifted and Talented, or G&T, programs have long been a perennial subject of debate, particularly in New York City, where it has bedeviled mayors for years. Some parents have already washed their hands of the whole G&T business, refusing to participate in what they view as a corrupt system of segregation. But countless others still place significant stock in the G&T designation and what it offers and are comfortable relying on cognitive testing, should it be required, to determine whether a child qualifies.
“When your intelligence is the foundation of your self-perception, failing to achieve feels like soul death,” writes Katie Arnold-Ratliff. But if the limited amount of information we have about gifted kids long-term is any indication, most lead, at best, ordinary lives of modest accomplishment. A 35-year study of 677 gifted children found that by age 50, only 12.3 percent had reached a level of “eminence,” defined as “full professors … Fortune 500 executives … judges and lawyers, leaders in biomedicine, award-winning journalists and writers.” This means 88 percent never did.
Arnold-Ratliff digs into the myth of the gifted child, and how our notions of intelligence may be inherently flawed:
