Traditional education can take you only so far, but it's truly self-education and a very specific form of it that will make you an exceptional thinker. Over my more than 13 years as a peer-reviewed scholar and educator, I eventually came across the work of the psychologist Robert Sternberg, as well as the step-by-step curriculum in his book, Teaching for Successful Intelligence. And as it turns out, it's this exact curriculum that the world's self-taught geniuses naturally practice, in one form or another.
In this video, I'm going to discuss four of these thinkers and explain how you can implement this curriculum for yourself. So, let's start with the first thinker, Michael Faraday, because his story is perhaps the best possible illustration of what this curriculum actually means in practice. You see, Faraday was the son of a blacksmith, apprentice to a bookbinder at 14, and had virtually no formal scientific education. And yet he became one of the most consequential scientists in history. The man who discovered electromagnetic induction, invented the electric motor, and laid the conceptual groundwork for everything from power generators to Maxwell's equations. But he didn't achieve all of this as a result of superior access to teachers or institutions. Instead, it was the result of a specific combination of elements underlying how he learned. And to understand what that combination actually was, we need to understand more fully the framework he and others we'll discuss were actually using.
In his book, Teaching for Successful Intelligence, the renowned psychologist Robert Sternberg argues that genuine intellectual performance depends on three distinct cognitive abilities working together rather than merely the IQ-based intelligence traditional education teaches to. The first is analytical thinking, the ability to analyze, evaluate, compare, and critique. The second is creative thinking, the ability to generate new ideas, reframe problems, and question assumptions. The third is practical thinking, the ability to translate what you know into action that actually works under real-world conditions.
In one landmark study, Sternberg took students and taught them the same material in four different ways. Through memory, or in other words, traditional educational methods, through analysis, through creativity, and through practical application. Then a fifth group was taught to engage all three non-memory modes simultaneously. And the results were striking. The high analytical group performed well on conventional tests. But the group using all three modes significantly outperformed every other group on every measure of actual achievement: homework, midterm exams, final exams, and independent projects.
And so what Sternberg's research is really telling us is this. Analytical intelligence alone produces people who perform well inside closed systems: school, standardized tests, structured environments where the rules are handed to you. But all three together produce people who perform well in open systems: careers, businesses, creative fields, life. And the gap between those two outcomes is not small at all.
And so let's bring this back to Faraday. Analytically, he was meticulous to an almost obsessive degree. His laboratory notebooks, which still exist today, are extraordinary documents of systematic observation. He didn't simply record what happened like most people, even very intelligent people do. No, instead he recorded what he expected to happen, why it didn't, and what that discrepancy implied. This is precisely what Sternberg identifies as one of the most critical analytical skills: representing and organizing information. You see, most people record the outcomes of things. Yet, Faraday recorded the structure of the problem, the relationship between the variables, the shape of the phenomenon, the pattern underneath the data. And it was that representational discipline that allowed him to see what everyone else missed.
With respect to creative intelligence, he invented the concept of field lines. The idea that electromagnetic forces propagate through space in structured, visualizable patterns rather than acting mysteriously at a distance. The mathematicians of his day couldn't accept it because it didn't fit their existing frameworks. Yet, he had done what Sternberg calls redefining the problem. He didn't ask, "How do magnets attract metal?" Instead, he asked, "What is the structure of the space between them?" And you see, that's a completely different question, and it opened an entirely different set of answers.
And so here's a Faraday-inspired exercise drawn directly from Sternberg's curriculum in the book. Take any concept you're currently studying or any problem you're working on and represent it in three completely different formats. First, write it as a sequence of causes and effects. What produces what and in what order? Then draw it as a diagram showing the relationships between its parts. Which elements depend on which. Then compress it into a single sentence that captures the core tension or the fundamental question it raises. You see, most people use one representation and assume they understand the thing. But the representation you choose is already deciding what you can and cannot see. And in fact, you can find many more exercises to train yourself on this skill in Sternberg's book itself.
But while Faraday mastered the art of seeing what's actually there, Frederick Douglass mastered something different: the art of reframing what everyone else had already accepted as settled. Douglass was born into slavery in Maryland, taught himself to read in secret using a spelling book and the help of a neighbor's children, and went on to become one of the most powerful orators, writers, and political strategists in American history. Yet, he had no formal education. Instead, what he did have was a ferocious and disciplined commitment to thinking in all three modes at once and the self-awareness to know which mode a given situation demanded.
Analytically, Douglass was a genius. His speeches and writing dismantled pro-slavery arguments with a logical precision that left his opponents with nothing to stand on. He made far more than emotional appeals, and instead identified the hidden premises, the unexamined assumptions, and the places where an argument required a claim that couldn't survive scrutiny once it was made explicit. He did exactly what Sternberg's analytical curriculum trains: evaluate evidence carefully, detect weaknesses in opposing positions, and refuse to let a claim pass unexamined simply because it is widely held.
Creatively speaking, Douglass understood that the most effective way to challenge a deeply entrenched position is not to attack it head-on, but instead to reframe the entire question. When pro-slavery advocates argued from scripture, Douglass didn't argue against their interpretation of that scripture. Instead, he questioned whether the frame itself, namely that scripture could ever be used to justify human bondage, was a legitimate frame at all. That move from rebuttal to reframing is precisely what Sternberg means by creative intelligence.
And with respect to practical intelligence, Douglass understood his audiences with exceptional precision, timing his arguments differently, adjusting his register and his emphasis depending on whether he was speaking to abolitionist allies, religious congregations, or political figures, and he sold his ideas, which Sternberg identifies explicitly as a distinct and trainable creative practical skill, and one most people never think to practice deliberately.
And so here's a Douglass-inspired exercise drawn directly from the curriculum in Sternberg's book. Take any position you currently hold on a business problem, a personal decision, or a contested idea in your field, and write the strongest possible version of the argument against it. Not just a straw man version, the real version, the one that would actually give you pause. And then ask yourself, what would I have to reframe, not just rebut, to genuinely move someone who holds this view? In other words, what wording or even concepts could I use differently that would lead to a different interpretation? This is what Sternberg calls questioning and analyzing assumptions, and it sits at the intersection of analytical and creative intelligence. In fact, it's one of the rarest cognitive habits you can build and one of the most powerful. And if you want to train yourself further on both of these skill sets, then of course you can find more practical exercises in Sternberg's book itself. But you can also feel free to check out my free critical thinking masterclass at the link in the pin comment below.
Now, our next self-taught genius here, Nikola Tesla, shows us something different from both Faraday and Douglass, and in some ways even more instructive, precisely because his story is a warning as much as an inspiration. Nikola Tesla was largely self-educated beyond basic schooling. Analytically, his intuitions about electromagnetic systems were precise enough to function as essentially mathematical proofs. In the domain of creative intelligence, his ability to visualize complete working machines in his mind, to mentally run them through testing cycles, identify failure points, and redesign them before building a single physical component, was a form of creative intelligence that went beyond anything his contemporaries could match. He designed his alternating current motor entirely in his imagination.
But Tesla's life also illustrates one of Sternberg's most important warnings about what happens when practical intelligence is neglected. You see, Sternberg is explicit that what he calls selling your ideas is not a personality trait. It's a cognitive skill, and one that can be trained or left undeveloped like any other. Yet Tesla consistently failed to develop it. He couldn't translate his vision into terms that actually persuaded investors, institutions, or even the public. He lacked the practical ability to make others understand why his ideas mattered and what to do about them right now.
And so, here's a Tesla-inspired exercise from the curriculum laid out in Sternberg's book. Once you've developed an idea you believe in or learn something you think is genuinely important, force yourself to write three versions of an explanation. One for a deep expert in the field, technically precise, no simplification. One for a curious and intelligent non-expert, conceptually clear, no jargon. And one for someone who has a specific, practical, immediate reason to care about it right now: concrete, actionable, relevant to their situation today. Where the third explanation breaks down completely is exactly where your practical intelligence needs the most work. Tesla could do version one with genius. Yet, it was version three that cost him credit for some of the most important inventions in the modern era.
And finally, there's our final self-taught genius here, Temple Grandin, the thinker who most completely embodies what Sternberg's research points toward as the ideal. Grandin is a professor of animal science, a designer of livestock handling systems now used in facilities across North America, and an autism advocate who has fundamentally changed how the scientific community understands animal cognition and welfare. She had no formal training in engineering or facility design. Instead, what she had was a way of perceiving the world that gave her direct access to information that neurotypical observers consistently missed, and a relentless, disciplined commitment to turning that perception into something that actually worked in the physical world.
Analytically speaking, Grandin is methodical in a way most formally trained professionals simply are not. She observes exhaustively, records systematically, and refuses to accept a design as finished until she has identified the precise cause of every problem it produces. In terms of creative intelligence, Sternberg identifies what he calls recognizing the two faces of knowledge as a key creative skill: the understanding that existing expertise can simultaneously illuminate a problem and blind you to its solution. Grandin didn't have the trained experts' blind spots because she simply hadn't been trained in them. Her perceptual difference therefore gave her direct, embodied access to the animals' experience of a facility, which is exactly the information that the conventionally trained designers were structurally unable to access.
And in terms of practical intelligence, everything she has ever thought has been aimed at implementation. She translates her insights into a specific, buildable, testable design change, and she perseveres through institutional resistance, which Sternberg identifies as one of the most critical and most commonly neglected practical skills, until the thing is actually constructed and functioning in the real world.
But the question remains, where do your own strengths currently lie? In the analytical, in the creative, in the practical? And which aspects of your thinking do you need to improve the most? Well, I encourage you to actually try the exercises in Sternberg's curriculum, adapt them to your own situation, and watch yourself start to transform into the same type of thinker we've discussed here. If you want to keep leveling up your critical thinking to make a massive impact not only on your own life, but also on the lives of countless others, then be sure to watch this next.
