Many people object to intelligence tests. Some people say that IQ test scores are often misused. They say this is unfair because when children “fail” these tests it can mean that they receive a worse secondary education than their more successful peers – the consequences of which can cost them throughout their lives. Does matter. Some people object to IQ testing for purely personal reasons and recall how stressed they were when sitting for this test. Many doubted that the results of this test were a fair reflection of his future potential. But how useful are IQ tests really? And what skills and qualities do they miss? Speaking on this, expert Lawrence Whalley of the University of Aberdeen said, “More than 30 years ago, I discovered a forgotten, unique collection of more than 89,000 IQ-like tests taken in 1932. It contained information about Scottish children born in 1921. “It included almost the entire national sample of 1800—who at the time of the discovery of this collection—would have been approximately 76 years old.”

My objective was simple: Finding local people to match with the collection and comparing their current mental ability to their test results from 1932. A picture quickly emerged linking low IQ scores to earlier-than-expected age at death and early-onset dementia. World War II produced some strong unexpected anomalies. Young men with higher childhood IQ scores are more likely to die during active service. Girls with higher scores often move away from the field. I cycled around Aberdeen to learn more about its social history, and visited the primary schools where children sat exams in 1932. Average IQ scores often varied significantly between schools. Students studying in schools in overcrowded districts performed less well on the test. Our subsequent research showed that people with higher IQs engaged in more intellectually stimulating activities, such as reading complex novels or learning musical instruments. But we cannot know whether having a high IQ simply attracts people to such activities or whether intellectually curious people develop high IQ because they are engaged in cognitively complex tasks throughout their lives. And this is an important question. People from poor backgrounds in deprived areas such as Aberdeen may not have the opportunity to pursue intellectual interests due to lack of time and resources. To do my job better, I sought out local residents with long experience of teaching in Aberdeen. His views are also echoed by current workers in public health and psychology.

Teachers warned me not to forget that IQ tests have been used for years to further “scientific racism” and that they fear it is not long before, right-wing proponents of IQ testing Would like to use this Scottish data to discover the genetic basis of intelligence. Concerned and now forewarned, I looked at the reasons for surveying the mental capacity of Scottish schoolchildren in 1932. The survey was funded by the Eugenics Society (eugenics is the science of improving the human race through the selection of ”good” hereditary traits) with some help from the Rockefeller Foundation. Their shared priority was to show the connection between large family size and below-average mental ability. At the time, it was easy to show this negative relationship between mothers’ IQ and childbearing. But post-1945 educational reforms, which led to more girls completing higher education, led to much more complex relationships between maternal intelligence, educational achievement, age at first child birth, and lifetime fertility. This led to contemporary public concerns that the loss of so many young men of above average ability during World War I had lowered the average mental ability of the general population. The newspapers argued that schoolchildren most likely to benefit would need to be evaluated and selected in order to give them a better education. This just goes to show that IQ tests can tell us something about academic success or dementia risk, but they miss a lot of nuances. It cannot be denied that these have long been used for dubious reasons – often as an excuse to direct less funding to certain types of schools, thereby creating a two-tier system. Most children who do not take or pass IQ-style entrance tests to private or grammar schools will have many qualities that would not be measured in an IQ test. They may develop intelligence in future. What don’t IQ tests measure? So what does an IQ test miss? Research shows that IQ scores rose by about 3 points per decade during the 20th century, but have declined over the past 30 years. Some experts argue that this reflects changes in school curriculum or perhaps the complexity of modern life. The adoption of “content knowledge” (reading and memorization) became a cornerstone of public examinations and is related to IQ test performance.

For example we know that working memory is related to IQ test performance. But research has shown that self-discipline is actually a better predictor of test results than IQ.

Nowadays, children in the West are taught collective scientific problem-solving with interpersonal skills and teamwork, which requires less memorization (cramming). This may actually make students less likely to score high on IQ tests, even though these methods are helping humanity as a whole become smarter. Knowledge continues to grow, often as a result of large research collaborations. This type of “process learning” leads to mature self-awareness, emotional stability, recognition of the thoughts and feelings of others, and an understanding of an individual’s impact on group performance. Critically, a lack of these skills can hinder rational thinking. Research shows that when we ignore or fail to understand our emotions, we are easily controlled by them. High intelligence does not necessarily protect against bias or mistakes. In fact, research shows that people with higher IQs may be especially sensitive to mistakes such as spotting patterns, even when there are no patterns, or they are irrelevant. This can lead to confirmation bias and difficulty giving up on an idea, solution, or project, even if it isn’t working. It can also get in the way of rational reasoning. But IQ tests do not reveal such weaknesses. Many of the great leaps in human ingenuity were driven by creativity, collaboration, competition, intuition, or curiosity rather than simply individual intelligence.

Take Albert Einstein, who is often hailed as a genius. He never took an IQ test, but people continue to speculate about his IQ. Yet he often credited curiosity and intuition as the main driving forces of scientific success – and these are not qualities measured by IQ tests. The ethos of a modern school is not driven by the priority of educating only those children who meet the minimum standard on mental testing upon selection. The schools recognize that educational outcomes are not determined solely by any innate ability, but are equally influenced by all prior experiences that influence emotional abilities, motivation, intellectual curiosity, insight, and intuitive reasoning. When local participants in the 1932 survey were interviewed later in life, they spoke warmly of their school days – especially about friendships. However he rarely mentioned his education. Mere rote learning with threats of physical punishment was not considered good. Some people recalled their experience of taking an IQ test in 1932 and were pleased that most schools no longer test children that way.
