Creativity Hack: Combining Unrelated Ideas

One of the most potent ways to find creative ideas is to take two completely unrelated concepts and try to combine them. This ability to associate unrelated ideas is a natural process for our brains but we often underuse this capability in finding novel ideas.  

About The Hack

Associative thinking, the ability to combine unrelated ideas, underlies a lot of innovation we see in the real world. Google search, one of the most well known inventions, is the product of associative thinking. When Sergei Brin and Larry Page were students working on improving search, they hit upon an interesting insight. The problem that they were trying to solve is to point users to high quality web pages that contain information users would find useful But how do you determine which websites are good and which ones are not? Their “aha” moment came when they realized that academic journals have a mechanism to identify high quality papers — the number of times a paper is cited by others. Applying the same concept to web pages, they realized that the more a web page is linked to by others the more authoritative it must be. They used that idea to create their first algorithm to rank web pages and Google was born! 

To use associative thinking in product design, find random objects or concepts and try to connect it to your central problem. For example, suppose you are tasked with making a new kind of mug. You then think of different objects or attributes, not typically associated with a mug, and see if there are ways to combine it. Suppose you picked a ball to combine with a mug. The simplest way to combine would be a ball-shaped mug. But, you could go further and use an attribute of the ball in a more meaningful way. Let’s say you pick “inflatable” as an aspect to incorporate. That leads you to creating an inflatable mug that is easy to pack on trips and provides good thermal insulation thanks to the layer of air in between. 

Summary

Finally, here is a quick summary of the creativity hack and how to use it in product design or with students.

DescriptionTo find a creative idea for product improvement, try to combine a random object or attribute with the product. 
ExampleIn designing a new kind of mug, you combine it with a ball. One attribute of the ball is “inflatable” which leads to the idea of an inflatable mug. The mug is useful because it packs more easily for hiking trips and also provides better thermal insulation due to the layer of air in between.  
Tips Instead of combining objects directly, use an attribute of the random object to combine. That often leads to more interesting and novel ideas  
ExtensionsTo build associative thinking in students, ask them to incorporate other famous characters (fictional or otherwise) into their stories, or do a project that combines their hobbies with a subject they are learning (e.g. music and math)

What Neuroscience Tells Us About Learning

Students today spend more time on academic learning than generations before. They cover more ground – learning things like programming or environmental science that their parents didn’t have to fret about – and spend more hours doing homework after school. One study found that in the sixteen-year period from 1981 to 1997, there was a 25% decrease in time spent playing outside and a 145% increase in time spent doing homework. 

As our society advances even more, students will have to cover more and more content, not just during their K1-2 school years but throughout their careers. By some estimates, students growing up today will have to learn entirely new domains and reinvent their careers every few years. Learning is no longer limited to younger ages but is becoming a lifelong journey. 

What does this really imply?

Students have to learn to learn –  acquire knowledge and master concepts faster – without which they will find it harder to stay abreast of new developments coming their way. But it’s not just about superficially memorizing things. Students will have to understand how to apply their newfound knowledge to problem-solving. In other words, learning has to become a more efficient process in terms of speed, depth, and understanding.

Thankfully, advances in neuroscience are giving us clues on how to make learning more efficient. Understanding how the brain processes information can help students take charge of their own learning, not just in their student years but throughout their life.

Neuroscience Of How Our Brain Learns

At a high level, we can view learning as a three-step process. When we encounter any new information, our brain first encodes this information and places it in short-term memory. For example, if you come across a new fact, say learning about a new breed of dog, the information first goes into your short-term memory. The next day, you might recall that your childhood friend had a similar-looking dog, and now you start to remember other details about the dog – how friendly it was, how it played, and so on.

At this stage, your memory is in long-term storage; it continuously consolidates other pieces of information that you already had. Over time you might add more connections to this piece of information, maybe a joke you heard about it, and it starts to get more and more enmeshed with other pieces of memory. 

After a few days, you might forget the name of the breed and try to recall it. You struggle a bit and then remember your friend’s dog, the joke, and other bits of memory that were tied to it. And then the name suddenly comes back to you, and you get a sudden burst of relief! 

A few days later, as you share a story about your childhood friend, her dog and the name of the breed come to your mind effortlessly, and you marvel at how well you remember this now. 

The picture above encapsulates how our memory works. Once we consolidate information into our long-term memory, subsequent retrieval and reconsolidation help to strengthen the memory traces and make it easier to recall information in the future. 

Forgetting Is The Path To Learning

Over the last couple of decades, neuroscientists have discovered interesting things about how our memory works, and counterintuitive as it sounds, forgetting information is an important aspect of remembering! Our brain is constantly pruning information that it thinks it doesn’t need so that it can serve the really important bits of information faster. 

Imagine if your brain stored every little nugget of information that it receives – the color of the shirt a passenger wore in the subway, or the name of the street your friend in another state lives on – it would make it much harder to find the useful information that you really need. So if you don’t need any piece of information, its retrieval strength starts to get weaker. However, when you try to recall something that you have forgotten, i.e., when you have to struggle a bit to remember it, that’s when the brain gets a cue that this particular memory is important and might be needed again.

So, with the process of retrieval, it starts to reconsolidate the information – find newer connections to other traces of memory so the memory is stored more strongly. As a result, this process of forgetting and remembering actually helps you learn better. 

Neuroscience-based memory models give us clues on how to structure our learning for maximum effectiveness. Here are three ways to boost your learning.

Repurpose Failure

When students don’t remember or don’t apply concepts correctly, it’s a sign that the information has been stored weakly in the brain. However, instead of feeling that they are ‘not cut out’ for this kind of work, students need to understand that their failure is simply a sign for their brain to reconfigure and become more efficient. Human brains are designed to learn through mistakes, so it makes sense to reframe forgetting as what it really is – a trigger that tells us that we need to take additional steps to ensure learning is complete. Students should use the opportunity to review concepts again and try to reconcile the mistakes so their understanding of the subject increases.  

Adopt Active Learning Strategies & Neuroscience

Adding some challenge to the learning process that taps our brain’s natural mechanisms to process, store and understand information can significantly boost learning. Such challenges are ‘desirable difficulties’ because they make learning more efficient. Here are a few strategies that students and teachers can adopt: 

  • Retrieval Practice: When learning new information, periodically quiz yourself about the central ideas and new terms encountered without looking at the text. This forces your brain to fetch the answers from long-term memory, and repeated retrieval is going to strengthen your memory.
  • Spaced Learning: To add more desirable difficulty to learning, practice retrievals after a period of time. When you start forgetting, you exert more effort in trying to remember, which then cues the brain to store the information more deeply. The gap between learning and retrieving can be anything from a day to a week – the key is that the gap should allow for some forgetting to happen.
  • Interleaving: Instead of waiting to thoroughly master one concept before moving on to the next, try mixing up different kinds of problems or concepts once you feel you have gained sufficient understanding in one. Not only does this make good use of spacing, but it also allows you to spot connections or differences between different kinds of problems. 

Research studies show that such strategies can be very effective in the classroom. In one study, students who practiced math problems in three sessions spaced apart by a week performed twice as well on the final test compared to students who did all the practice problems in one session.  In another study, students performed significantly better on their science exam when a practice quiz one month before the exam interleaved concepts on the quiz. 

Associative Learning & Neuroscience

Another useful strategy in learning is to connect the information you are learning to other pieces of knowledge you already possess. If retrieval practice creates deep roots, then associative learning creates more branches that help anchor the information better. To build associative learning

  • Find an analogy: Ask yourself if the new concept is similar to any other piece of information that you already possess. As an example, you might make a connection between gravity and magnetism as both involve a force that they can’t see and attract objects. 
  • Find a personal connection: In some cases, your personal experience can be helpful in finding connections about what you are learning. For example, while learning about the ice age, you might remember an earlier trip to Grand Coulee, where they saw how the Missoula Floods carved out a massive canyon in a very short time. The scale and impact of the event will give you an enhanced perspective of the topic and deepen your understanding. 

Conclusion

By understanding the neuroscience behind learning, students can take charge of their own learning. The key to efficient learning is to add and embrace the right kind of challenges that push our brains to reconfigure themselves. Unless students lack relevant background or specific skills to make sense of the concept in front of them, such challenges should be welcomed instead of dread. 

With a deeper understanding of the learning process, students can try different approaches and customize them to their needs. As an example, for some students, one day of spacing might be enough, whereas, for others, it might be a week. For the latter set, practicing a skill every day might not be as effective because they haven’t forgotten enough for reconsolidation to take place. With some trial and error, students can identify strategies that work best for them and become smart learners.

Cognitive Underpinnings of Creative Thinking

50,000 years ago humans shared the land with other hominins like the Neanderthals and the Denisovans. But somehow, over the course of the next 30,000 years, every other hominin species went extinct while the modern day humans saw huge growth and advancement.

Some people point to the development of language and tools that gave us a Darwinian edge. But evidence of language and tools, some of which were fairly sophisticated, have been found in Neanderthals and the other hominins. So what made us special?

According to Thomas Suddendorf, professor and author, what set us apart was not language or tools, rudimentary forms of which exist in other animals, but our ability to do open-ended imagination and make connections between different concepts. This enabled us to do mental “time travel”, going back in time and in the future, and allowed us to foresee and plan for our survival. In addition, making connections allowed us to find novel and interesting solutions to problems that we faced.

From a cognitive perspective, our brain allows us to voluntarily think of a concept which then triggers another concept, which in turn triggers the next one and so on, leading to a stream of thought, something that likely doesn’t exist in other animals. As Professor Liane Gabora explains, “With this ‘self-triggered recall and rehearsal loop’ we could now activate and re-activate visions and dreams, such that with each successive conception of them they were looked at from a different angle, embedded a little more firmly in the constraints of reality as we know it, and potentially turned into a form in which they could be realized.”

This cognitive ability is the direct result of how our brain stores information associatively, and is the reason why humans are able to come up with novel and creative ideas.

Think about how a computer stores information. To store the word “apple” in computer memory, each word is broken down to its letters and each letter in turn is converted to its binary code and stored. For example, the binary code for “a” is “01100001”, for “p” is “01110000” and so on. That’s not how human brains store information.

Human brains store each concept as a whole, connected to other concepts. So the word “apple” is stored as a concept by itself and is linked to other concepts with different kinds of links. So “apple” might be connected to “fruit” by a thing to category link, to “red” by a thing to property link, or “rash” by a cause and effect link if someone is allergic to apples. These links have different strengths in the brain so the dominant link for one person might be apple to red, but apple to fruit for someone else.

When you consciously think of an idea, your brain automatically activates some of the connecting ideas and brings them into your consciousness, leading to a stream of thought.

This also explains why it is sometimes hard to think of new ideas or solutions. As we think about a problem, some of these links get reinforced and strengthened making it hard to change perspective or think in a different direction. In other words, “These same pathways, however, also become the mental ruts that make it difficult to reorganize the information mentally so as to see it from a different perspective.”

The associative nature of the brain also comes into play when it encounters ideas that are not related. To see how this works, look at the two words below:

                          Bananas                            Vomit

If you are like most people, the moment you read the two words, your brain automatically tried to connect the unrelated words with a causal connection, forming a scenario where eating bananas led to vomiting, leaving you with a somewhat unpleasant feeling. 

You didn’t have to consciously think of this, your brain did the work of finding the best possible connection between the two words.

These two aspects of the associative nature of our brain – activating connected ideas and finding connections between random ideas – are what make it possible for us to think creatively. In fact, most creative thinking techniques rely on these two underlying mechanisms in one form or the other to generate novel ideas.

  1. Traversing Connected Ideas: Techniques like “Slice and Dice” and “Cherry Split” in Thinkertoys or segmentation in TRIZ, work by forcing the brain to traverse different paths in the associative network by explicitly listing out the triggers.
  2. Adding a Random Component: By simply introducing a random element into the mix, the brain automatically tries to find the best way to incorporate the random element into the solution. Techniques like the “Brute Think” and “Hall of Fame” in Thinkertoys are an example of such an approach.

What made us come so far is likely because of our unique cognitive strengths – how we store and process information in our brains, combine different ideas and run mental simulations. These strengths allowed us to solve problems, make inventions and build on each others ideas, and they just might turn out to be key for our future as well.

A Summer Full of Inventions

After an exciting and busy spell, we recently concluded our summer programs that introduced children to creativity and inventing.

This year, we expanded on our summer camp from last year. We ran our invention themed camps for two age groups – a younger group (1st – 4th grade) and an older group (5th – 8th). The younger group had weekly invention themes (like inventions to simplify chores, making functional clothes etc). For the older group, we did a 2-week camp in collaboration with the Archimedes School (who taught 3D printing). The students made pressure sensors from individual components, 3D printed a casing for their sensors and then used creative thinking techniques to come up with new inventions that would use pressure sensors in a meaningful way.

Our goal was for children to experience the entire creative flow from ideation to prototyping, and learn creativity skills that would last them for longer. Through these creativity techniques, we wanted children to come up with many different ideas to solve a problem. In fact, with the older group, we even tallied how many ideas they got with and without using creativity techniques. Everyone in that group was able to come up with 2x-3x more ideas by using one of the creative thinking approaches! Here are the things we focused on in our camps:

  • Understanding Creativity: We started each camp with discussing what creativity means – that it involves coming up with ideas that are both original and useful.  Creativity is often confused with art, and it was helpful to clarify that in the beginning with a discussion of what makes something creative.
  • Creativity Techniques: For both groups, we focused on two core creative thinking techniques to coming up with original ideas – “Put to Another Use” and “Associative Thinking“. Being able to adapt an object for a different use and finding ways to combine a random object or concept, are fundamental processes in thinking creatively and seem to underlie other creativity techniques. The older group also did other techniques like reversing assumptions, and processes like MindMapping to help them brainstorm more effectively.
  • Evaluating Creativity: While it’s important to understand what creativity is, we thought it would be even better if the students knew how they can measure creativity. So, everyone had to evaluate their own as well as others’ ideas on “originality” and “usefulness”. The older group also rated ideas on “impact” and “practicality”. This exercise really helped them in picking the most creative ones to pursue in a systematic way.
  • Telling a Story: It’s not enough to come up with a good idea – selling an idea is just as important. So we introduced storytelling and storyboarding concepts to help them tell a compelling story about their invention. The older group pitched their idea to the rest of the group and got useful feedback on their invention and pitch in return.  

We were truly heartened to see even the younger children apply these concepts and come up with creative ideas. And we ended up with some very neat inventions in the process!

The younger group came up with ideas like a sweater that converts into a hammock using drawstrings on the collar and bottom (notice the “Put to another use” skill being used here?), a pot with removable handles that also serve as spatulas, a couch with easy access storage bins and many more!

The older group used pressure sensor in many different ways and after searching through the patent database picked ideas that they believed were sufficiently unique and useful. We had a safe stovetop that will switch off when there is no pan on it, a laundry hamper that reminds you to do your laundry regularly, a pencil grip that detects when you are under stress and pressing too hard and several more. And what truly warmed our hearts was when one of the students commented during the demo day, “If all of these were not just prototypes, the world would be so much better!“

We had a great time watching  our 40+ campers learn to play with ideas and hope they are inspired to continue their inventive journey beyond our summer camp.
