Intelligence and connections: why your brain needs to communicate well with itself


Research from the California Institute of Technology showed that intelligence is something found all across the brain, rather than in one specific region:

The researchers found that, rather than residing in a single structure, general intelligence is determined by a network of regions across both sides of the brain.


One of the researchers explained that the study showed the brain working as a distributed system:

“Several brain regions, and the connections between them, were what was most important to general intelligence,” explains Gläscher.


The study also supported an existing theory about intelligence that says general intelligence is based on the brain’s ability to pull together and integrate various kinds of processing, such as working memory.


At Washington University, a research study found that connectivity with a particular area of the prefrontal cortex has a correlation with a person’s general intelligence.


This study showed that intelligence relied partly on high functioning brain areas, and partly on their ability to communicate with other areas in the brain.


Aside from physical connectivity in the brain, being able to make connections between ideas and knowledge we hold in our memories can help us to think more creatively and produce higher quality work.

Connections fuel creativity: nothing is original

Steve Jobs is an obvious person to reference whenever you’re talking about creativity or innovation, so I wasn’t surprised to find that he has spoken about making connections before. This great quote is from a Wired interview in 1996:

Creativity is just connecting things. When you ask creative people how they did something, they feel a little guilty because they didn’t really do it, they just saw something.

Jobs went on to explain that experience (as we saw in the image at the top of this post) is the secret to being able to make connections so readily:

That’s because they were able to connect experiences they’ve had and synthesize new things. And the reason they were able to do that was that they’ve had more experiences or they have thought more about their experiences than other people.

Maria Popova is arguably one of the best examples (and proponents) of what she calls “combinatorial creativity.” That is, connecting things to create new ideas:

… in order for us to truly create and contribute to the world, we have to be able to connect countless dots, to cross-pollinate ideas from a wealth of disciplines, to combine and recombine these pieces and build new castles.

… something we all understand on a deep intuitive level, but our creative egos sort of don’t really want to accept: And that is the idea that creativity is combinatorial, that nothing is entirely original, that everything builds on what came before…

My favorite part of this talk is Popova’s LEGO analogy, where she likens the dots of knowledge we have to LEGO building blocks:

The more of these building blocks we have, and the more diverse their shapes and colors, the more interesting our castles will become.

Author Austin Kleon is someone who immediately comes to mind whenever the topic of connections and remixing art comes up. Kleon is the author of Steal Like An Artist, a book about using the work of others to inspire and inform your own.

Every artist gets asked the question, “Where do you get your ideas?”

The honest artist answers, “I steal them.”

Kleon is inspiring because he’s so upfront about how the work of other people has become part of his own work. He’s also keen on the phrase I quoted from Maria Popova above, that “nothing is original”:

Every new idea is just a mashup or a remix of one or more previous ideas.

If you’re looking for advice on creating more connections between the knowledge you have (and collecting even more knowledge), Kleon’s book is a great place to start. He offers suggests like:

• carry a notebook everywhere
• read a lot
• keep a scratch file
