I previously talked about how scores on an IQ test are developed, and what they mean mathematically. Now, I’ll look at what they can mean for individuals.
IQ scores can be seen as the mind equivalent of BMI scores. Although both numbers can provide useful information when averaged across large groups, they shouldn’t be used to directly compare individuals, or used to sum up a person in one statistic. BMI can be helpful for an average-height and middling-framed Western person, but it is near-useless for athletes, who will often score as overweight or obese due to their increased muscle mass. Similarly, IQ measurements may be an accurate representation for a neurotypical person who is familiar with Western education systems and standardized testing. But they are not an accurate summation for people with neurodevelopmental disorders, or people who aren’t used to standardised tests and solving problems in a room with a stranger.
3) IQ tests cannot always measure someone’s ability accurately. Health conditions and neurological differences result in people having uneven patterns of ability, which confuse IQ tests.
The Intelligence Quotient- or IQ- is one of the most popular subjects in psychology. Yet despite us often using IQ as a shorthand for intelligence, and even using it to define others, misconceptions about IQ are often louder than explanations.
So how do IQ tests work, and what does an IQ score mean?
1) An IQ test does not directly measure your ability. It uses maths to estimate your ability in relation to other people.
Most reality shows spark controversy, and Child Genius is no exception. Series finales are often followed by arguments that the show placed too much pressure on contestants, while the 2017 series was also interrupted by accusations of cheating parents.
Today I’m going to talk about another issue; how the competition and the programme portrays “intelligence” and “genius” in a one-dimensional way which reinforces misconceptions about intelligence.
