If somebody screwed with a bicycle so that the handlebars worked in the opposite way to usual (left goes right, and right goes left), do you think you could ride it? Many people do, according to Smarter Every Day’s Destin Sandlin. Until they get on the bike.

In his video, Destin illuminates a valuable insight: knowledge doesn’t equal understanding. He had the knowledge that he needed to ride the backwards bike—turn the handlebars in the opposite way to usual—but he didn’t have the understanding (or the deep understanding) of how to do it.

The difference between the two concepts is key. Knowledge can be considered as an acquaintance with facts or principles, a familiarity or awareness of something. Understanding goes to the very heart of a concept, requiring a thorough and comprehensive grasp. Often, we can’t explain why we understand something, as it requires an aspect of intelligence that is separate from language. Riding a bike is an example of this—the most articulate person on the planet couldn’t teach a child to ride a bike using just words, as it requires spatial and bodily-kinesthetic skill. Only by getting on the bike itself can the kid begin the journey to BMX-champion stardom.

There’s nothing wrong with being a dabbling dilettante; engaging in multiple things can help you to discover what you’re passionate about. Curiosity can lead you to great places. If we want a true and deep understanding though, it requires a lot more than skimming the surface. You can’t read a Nietzsche book and expect to be an expert on existentialism, or to see an immediate positive impact in your own life. You’ll need to read similar books, analyse and evaluate the content thoroughly, and actively try to apply the concepts in your day-to-day. Passive reading just isn’t enough, even with a photographic memory. Deep understanding takes engagement, hard work and commitment.

Being actively engaged in something is one of the few ways to promote higher-order thinking, and this can only happen if you’re either genuinely interested in the topic, or are being pushed forward by a strong external motivation. Active learning is an effective educational process being used by universities the world over.

Ways to promote deep understanding

Do the thing

Want to learn how to surf? Get some surfing lessons, and then go surfing. Want to become a mathlete? Take some online courses, and then do math. Want to relate to people more deeply? Ask questions, and try to put yourself in their shoes. None of these things can be understood by just passively learning about them. Nobody taught you how to speak—as a child you instinctively knew that by making noises, you’d get what you wanted. You’re using the same method years later, just in a more articulate fashion (hopefully), and you learned it by doing.

You might be able to the list the amazing benefits of mindfulness meditation, but unless you actively engage in the practice itself, you’re never going to reap any of them. This is the simplest but most effective method for gaining deep understanding.

Apply it to problems in your life

Everybody has problems, and it can be difficult knowing how to fix them. Progress can only be made by giving something a try, and observing the results. By trying something, and evaluating the attempt afterwards, you’re gaining a deeper understanding of your chosen solution, regardless of whether it was a complete failure. Even abstract concepts of philosophy require a degree of practical action in order for us to properly understand them. Take utilitarianism (the idea that the end justifies the means) as an example. You might believe that chastising a rude shop assistant is the morally right thing to do, because they might adjust their behaviour towards people in future. But until you give it a try, observe the results, and then evaluate its effectiveness, you’ll never fully understand whether utilitarianism is the right approach in this example.

“I believe that the school must represent present life – life as real and vital to the child as that which he carries on in the home, in the neighborhood, or on the playground.”

John Dewey

“Theory without practice leads to an empty idealism, and action without philosophical reflection leads to mindless activism.”

John L. Elias and Sharan B. Merriam

Discuss and debate

Chatting with your spouse, friends and colleagues about a topic helps to cement the ideas in your brain, in addition to securing some much needed human intimacy. The associative nature of our brains allows discussion that adapts and diverts from the original point, strengthening the neural pathways surrounding the central topic, and advancing understanding in the process. We can learn a shitload from our friends, if we’re willing to listen and engage. Have the courage to be vulnerable and say what you really want to say; what you’re genuinely interested in. You can only get through so much weather small-talk because you find yourself going insane. Deep, meaningful conversation is a major factor for successful relationships, while at the same time promoting thorough understanding of the examined topics.

Analyse and evaluate

Pulling something apart into its core components—whether an engine, or a philosophical concept—helps to understand how the parts make up the whole. Some things are multi-faceted and incredibly complex—breaking them down into smaller chunks is an effective way to understand them better. We must critically analyse the details of a thing if we want to really know it, and compare and contrast it to things of a similar nature.

Evaluation is just as important. Only by reflecting on the value of what you’ve done can you determine whether it’s worth doing again.

Repetition

There’s a million cliches that espouse this message, and for good reason. Only by repeating something can you build the neural brain connections required for memory, and networks to similar concepts in your brain.

All of your senses can be used for repetition learning—by reading, watching videos, or listening to podcasts about the same concept, you’re forging valuable pathways that will promote understanding, while helping to keep things interesting through the use of different mediums.

“Neurons that fire together wire together.”

Donald Hebb, Canadian neuropsychologist

Write it down

Writing your ideas about a subject will help you to remember it, and formulate different notions surrounding it. Producing emotional writing—how you actually feel about the topic—also makes it more memorable. Dry, purely rational writing should be left to university assignments; these are your personal thoughts and feelings about a topic.

**

It’s easy to skim the surface of a subject without truly understanding it. You could be the pub-quiz champion of your town but actually know very little about your memorised facts. If you’re willing to dive deeper, with dedication and hard work you can turn simple knowledge into deep, fulfilling understanding.
