The IQ test is the most widely known measure of intelligence, but are the 'twice exceptional' and other gifted members of society slipping between the cracks?
Most of us know about the IQ test, whether you’ve taken one, read about it, or seen that episode of Seinfeld, it’s part of the lexicon when we talk about intelligence.
Conversely, here’s a less common term: ‘twice exceptional’, which is often abbreviated to 2e. This refers to those who have some form of disability but are also intellectually gifted (contrary to quick-fire biases, the two aren’t mutually exclusive). It’s this group – and people all across the intelligence and creativity spectrum – that misses out when aptitude is measured by what experts like Scott Barry Kaufman consider to be a fairly narrow test.
The IQ test was developed in the early 20th century, spring-boarding off the work of French psychologist Alfred Binet. It involves a series of standardized tests that measure a person’s mental age score, which is divided by their chronological age, and that fraction is then multiplied by 100 to obtain the IQ score. But the test has evolved over the 100 years since its inception, and even Binet’s work, which is often thought of as seminal, points to methods that he borrowed from other scholars. This mish-mash of tests has fluctuated over the years to reflect the values of the era, dropping tests that are seen as bad and retaining the ones that are considered good measures of intelligence.
But it has plenty of shapeshifting still to do, according to Kaufman. Intelligence takes many forms, and the IQ test doesn’t capture the full complexity of the human mind. Billionaire business magnate Richard Branson is an excellent example: "I was dyslexic, I had no understanding of schoolwork whatsoever. I certainly would have failed IQ tests. And it was one of the reasons I left school when I was 15 years old."
The IQ test doesn’t measure for factors like creativity, emotional sensitivity, real-world rationality, social intelligence and skills-based acumen. There are many ways to be gifted, and those who are twice exceptional or intellectually advanced outside of the normal parameters, can miss out on the developmental attention needed to cultivate their intellect to its full potential. Kaufman suggests retaining components of the IQ test to identify where people do well and spot intelligence patterns, but to also utilize new methodologies, and solicit parent and teacher readings as they are in a position to observe intelligence indicators day by day, such as deep sensitivity, questioning assumptions, or signs that a child is bored with their work. The more you can triangulate information from different sources, the better the measure of true intelligence will be.
If you’re now itching to know how you would perform on an IQ test, you can take one here, but don’t be too buoyed or disheartened by the results – intelligence is a sprawling entity that scientists are still mapping, and the IQ test is a well-worn but ultimately narrow path to tread.
