Bring Up Intelligence—How IQ tests do not measure how smart we really are

I can’t even begin counting the number of times people called me “smart” for studying science at a university level. And even though I am partly flattered, another more substantial part of me is outright annoyed. To be clear, I am understandably not a proponent of the maxim “You don’t need a rocket scientist to do this.” This idea that rocket scientists are at the top of the intelligence pyramid is downright arrogant. Yes, they are indeed brilliant, but there are also plenty of people in other fields that are equally smart. Be careful here; even non-scientist can be as intelligent as rocket scientists. So next time you feel compelled to tell your scientist friends how smart they are, remember to tell your local farmers how smart they are as well. We need to stop considering how intelligent people are by the amount of mathematical knowledge they master or how much academic content they can stuff into their brains. We may have understood now that intelligence is complex. Yet, we are still way behind when it comes to redefining how we view it in our modern society. 

Since the early 20th century, intelligence has been defined by how much you score on an Intelligence Quotient test (IQ test). Considering the average on the test to be 100, anyone who would score under 90 would classify as dull and the ones with scores under 70, mentally defective. On the contrary, individuals that score above 115 would be considered gifted. However, even though we created this test with the intention to measure intelligence, it only succeeded at evaluating the general factor, “g” (i.e. cognitive abilities). Indeed the questions asked often revolve around aspects like general knowledge, arithmetics, vocabulary, language comprehension, picture completion, block design, object assembly, coding, picture arrangement and similarities. This tool seemed so formidable and has been so successfully marketed as a universal intelligent test that most people today would readily believe them to measure intelligence. But beware that this test does not capture the whole picture of intelligence, and rating your job candidates on only this measure would be a complete travesty. 

There are, however, people out there that are genuine supporters of the IQ tests as a future performance predictor. Although these individuals are not entirely misguided -IQ tests do indeed show moderate correlation with future successes-, other measures have proven themselves even more reliable. For instance, emotional intelligence has proven itself a good predictor, along with self-control, faith over one’s future and interpersonal strategies. More impressively, in all those predictors, self-control actually was better at estimating one’s chance of success, even compared to IQ tests. And this brings me to wonder about the consequences of such an intelligence test. For me, it seems like a premature way to etiquette people into categories dictating if they should succeed or not. If we decide to attend university or apply for jobs, we can’t escape the ‘oh!’ so prevalent IQ tests, which may determine if we will get the job or not. And it seems that the more prestigious the place you are applying to, the more probable you will have to face one of these tests. So the test is no longer used merely as an indicator but as an obstacle too. We can only wonder from such observation if the success is truthfully linked to IQ scores or are the IQ scores deciding who should succeed or not? For me, this whole IQ thing really sounds like a self-fulfilling prophecy.

So if intelligence is not what IQ tests are calculating, then what is intelligence? Many psychologists and psychometrists attempted to describe it. Yet, nobody came up with a theory upon which everyone could agree. This disagreement over the definition arises from the different understanding that people have of intelligence. A mathematician, for example, may believe that intelligence is your ability to reason and compute complex problems; a physicist may think that it is the ability of one’s mind to picture abstract objects; an artist may perceive it to be the ability to create. And it is that flexibility in the concept that makes it hard to measure. I would even say that it is a vain pursuit to try measuring it. Intelligence is too complex and evidently a subjective notion. Yet, some theories seem better at summarizing the idea. 

In an attempt to correct how we saw intelligence, Robert Sternberg proposed the triarchic theory of intelligence. He started describing the classical view of intelligence as analytic intelligence. This one best describes how well we will do in an academic setting. It involves reasoning, computing, problem-solving, and more. As a second theory, he introduced creative intelligence. It best defines how someone can be innovative, inventive and a generator of new ideas. As the third and last, he brought up practical intelligence, which describes best the people that are particularly ‘street smart.’ Those individuals are known as people who can have a good idea of how things might turn out and avoid trouble. They typically know the best route, the best restaurant, the best contacts, etc. They also might have a better intuition about someone’s intention soon after meeting them for the first time.

Although this approach is much better than what IQ tests offered us, I find it still lacks complexity. It doesn’t yet capture the whole image of intelligence. And someone else, an American psychologist, came to a similar conclusion and proposed that we view intelligence as multimodal and not as one single unit, which agrees with what Sternberg previously offered. However, Gardner’s theory was slightly more ambitious as it officially encompasses nine types of intelligence, and unofficially, 10. Yet, given the lack of empirical evidence to support this idea, this theory is still being critiqued. Gardner’s approach was uniquely based on subjective judgement and observation. And since the whole concept is an abstract notion, to begin with, such as love and sadness -which we can’t measure either-, I find it quite suitable.  

We could probably group the first three under Sternberg’s view of analytic intelligence. And yet, I find this segmenting to be fairer. They are visual-spatial intelligence, linguistic-verbal intelligence and logical-mathematical intelligence. They are all probably very self-explanatory, but I can, at the very least, describe them a little. Visual-spatial intelligence refers to people who are good at locating themselves and finding directions. Basically, people who score high on this intelligence may be capable of mentally visualizing the whole itinerary when they travel somewhere. Individuals that score high in linguistic-verbal are often the ones we would describe as eloquent. They have a way with words, and they also have an easier time learning new languages. Well, logical-mathematical inclined people have an easier time following rules and creating new ones. They also excel at reasoning and critical thinking. 

As mentioned, there are at least six more to introduce, so I’ll be quick. These six types are bodily-kinesthetic, musical, interpersonal, intrapersonal, naturalistic, and existential. Bodily-kinesthetic people are better at orchestrating and fine-tuning their movement. It is why this type is most often called physical intelligence. Musical people have increased ease in determining the tone, sounds and rhythms of music. Interpersonal individuals are more skilled at networking and creating good long-lasting relationships. Intrapersonal refers to people that are finely tuned to their inner thought workings and are very good at introspection. Naturalistic intelligence characterizes people that can effortlessly draw links with nature. And existential intelligence was created as an alternative to spiritual intelligence, where people perceive that their lives have a higher purpose. At last, there is one remaining unofficial intelligence, which is digital intelligence. Its need arose from the accessibility to digital content.

To wrap up everything, let’s say that I particularly like Einstein’s quote: “if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid.“ It is truly an amazing analogy to describe how everyone can be intelligent in their own way. But if you test them all using the same standardized tools, you might miss what’s right under your nose. So, as a take-home message, I would like you to realize that some scientists are smart (on some modalities), but so can be dropout students (on different modalities). And most importantly, that you are intelligent too and never forget it. I’ll end this article with another clever quote from Einstein: “The measure of intelligence is the ability to change [or to adapt],” and I find that it englobes well the notion of intelligence. As humans, we are born with the ability to adapt, and as such, we are all intelligent.

Bring Up The Beginning – How it all started

I remember the night just before my first day of school, I was totally terrified. I had a nightmare that I was lost in the school and no one was willing to help me find my way back. They would instead ask me what was wrong with me. I was panicked. When I finally woke up, I unsurprisingly didn’t want to go to school. However, I have never mentioned it to my mother, since I knew what she would tell me. She would tell me to snap out of it and that I would have to go to school like any of my siblings. Let’s say that I never felt like there were any place for drama, or at least emotions, at home. So, I kept that detail for me.

Turns out maybe this dream may have been a warning for what was to come, but scientifically speaking it couldn’t. Reasonably speaking, it was probably only the expression of my worries. I always had trouble with changes and that was essentially an enormous one. There are probably multiple factors to account for my difficulties adapting to school. However, I think that the strongest factor was my emotional over-expressiveness. Difficulty controlling the expression of my feelings possibly made me a very easy target for intimidation. And so, by the middle of elementary school, I started getting bullied by a guy and that lasted through most of my high school years as well. This could probably have been enough for most people to become bitter about school and rebel against the institution, or, at the very least, produce a strong desire to quit attending school. Fortunately for me, this was far from the feeling I had toward school.

Let’s say that school was both a nightmare and my safe haven. Well, you may understand why this was a nightmare, but it isn’t all that clear why this was my very safe haven. You might think that home should have been my safe haven, but it wasn’t. At home, I never felt like I was doing enough. Everything I was doing was judged to be done badly. Additionally, things I was craving for like admiration or, at the very least, respect was nowhere to be found. On the contrary, at school, there existed both admiration and respect. I could make my teachers proud by using my knowledge to answer questions and when I answered correctly, they showed me praises. But moreover, there was no name calling or insults thrown. But sadly, I can’t say that all teachers were like that. I had one teacher in elementary school that picked on me. To this day, I regret not standing up to him, but what could I have done? I was only a kid.

Then again, most teachers were all very supportive, so by rules of generalization, I loved my teachers. Yet, what I like the most about school was its seemingly infinite source of information. Information that could potentially be knowledge. Knowledge was ultimately my escape. My escape from boredom, from loneliness, from intimidation and from injustice. As a kid, I perceived that knowledge could help solve all problems. With it, I could extrapolate answers to behaviours or to just any basic fundamental questions. My curiosity knew no boundaries and with curiosity arose multiple questions. School then became necessary and provided me with endless possibilities to see the world through another lens.

One question that I’ve had and that is now left mostly answered was the reasons behind my childhood harassment. I always wondered why children could be so hurtful and then I realized that one major difference between children and adults is their openness to differences. Pre-teenager and, to a lesser extent, teenagers have a strong desire to fit within a group (sense of belonging). They do it in such a way that their appearances, their thoughts, and their experiences must be kept as similar as to the rest of the gang. However, by the time they leave high school, they recognize that a quest for normality is vain and they have to develop a better awareness of themselves (identity). For example, the eight-year-old me talking science to classmates was probably interpreted as me pointing out what they ignored. This fact was enough to confirm that I didn’t fit in. Alternatively, adults realize that one human in its lifetime can’t learn everything the world has to offer. Most won’t feel offended or confronted by an individual possessing information that they don’t have.

Then, from my quest to gain knowledge came a natural appreciation toward science and eventually an admiration and a love for it. I was first introduced to science with a special book: a science encyclopedia for children. This book was lying in the bookshelves in my bedroom and since I had to stay in bed after waking up in the morning, I decided to open it. This book was perfectly designed and got me to be amazed by everything nature had to offer. Two articles really grabbed my attention. The first talked about the size of the largest mammal on Earth, the blue whale, which can measure up to three buses long. The second introduced the difference between the terms: storm, lightning, and thunder. 

I absolutely rejoice in acquiring knowledge, but acquiring it was only part of the joy it brought me. The most satisfaction I got was when I decided to share the knowledge. I genuinely thought that people would like to know everything as much as I did. Turns out this couldn’t be far enough away from the truth. It took me a few years to realize this. With this cluelessness came insults from my family and my friends telling me that I was a weirdo, that I talked too much, and that I was a big know-it-all. All that hurt led me to change my approach to science communication. With time I learnt that science can be communicated more easily to people that are truly interested and that interest is most often expressed through asking questions. If you pay attention to the questions, you can be there to answer them and thus communicating knowledge. My second realization is that too much science content on the internet right now is overly specific and needs previously acquired material to understand it.

I believe that this leads people to believe science is only accessible for educated people, but the truth is that everyone is doing science. Moreover, everyone is doing science every day. Your body is constantly doing chemistry by measuring blood sugar content and releasing corresponding levels of insulin. It is also doing physics every time you walk or run. It is also doing physiology whenever you experience pain or mathematics whenever you purchase something in a store. Science is not for an elite population; it’s for everyone. 

This is the reason Bring Up Science got created. My goal is to bring light to the science behind different elements of our life. From the first leaves in the trees in spring to the way we perceive pain. Science is a beautiful thing that everyone deserves to enjoy and that might just start with Bring Up Science. So, no matter where you are right now, what you’re doing or even if you know the fundamental principles of physics. What’s important is that you open yourself up to the amazing potential and accessibility of Science. It will make you appreciate life in a different perspective and maybe allow you to see all of yourself as a beautiful orchestra of science.
