Your brain is like an impatient friend who constantly tries to finish your next sentence. It likes to guess, predict, and expect nearly everything around you. You are taking a sip of coffee in the morning, like every day, and again, it knows exactly how it should taste. It knows it so well that if it didn’t run out of coffee or if it didn’t taste funky, you most likely won’t even notice making it, delightfully spending that time in the soft cloud of morning thoughts.

Because of that impatience, the brain is also prone to making mistakes. When our continuous predictions don’t match reality, we speak of a mismatch. Moments when the brain’s expectations do not fully match reality. Remember the time you moved to a new apartment? Everything felt new, unfamiliar. The task of figuring out which light switch lit up which lamp felt conscious and sometimes futile, leaving you guessing wrong for days. However, after a month, it became second nature. What once required full conscious attention became a routine as the brain had updated its predictions about the environment.

When a mismatch between prediction and reality occurs, the brain becomes more active as it tries to resolve it. As a result, information is processed more thoroughly. The activation spreads across the brain, allowing new connections to form once an answer emerges. You can imagine it as machines in your brain that, if fed with certain information, immediately produce an assigned reaction to it. New information can sometimes lead to the creation of a new machine. For example, the first time you hear a word in a foreign language, your brain works harder to process the unfamiliar sound, and gradually builds a new connection linking that word to its meaning. After enough repetition, recognising the word becomes automatic. New information can also be used to update existing machinery, making future predictions more accurate. Novelty stimulates cognition because it disrupts our expectations.

The balance between novelty and routine

While novelty activates the brain and sparks new connections, routine allows it to work smoothly and efficiently. Once something becomes familiar, the brain no longer has to work as hard. It can simply activate the machine it has already built. However, without the occasional updates and disturbances, those same machines keep running unchanged and quietly become less effective. The sweet spot sits somewhere in between, with enough routine to stay grounded and enough novelty to drive change. 

What this means for organisations

Even for companies, this matters. Routine is a key for efficiency. Thanks to it, brands are recognisable and teams dependable. But when everything becomes too familiar, the curtains, in turn, close so slightly that it eventually becomes almost forgettable. A product launch, a refreshed design, or an unexpected campaign can wake people up when it introduces a meaningful surprise. Not novelty for novelty’s sake. A change that interrupts expectation while still giving the brain something clear to grasp.

The same principle applies inside organisations. Innovation rarely emerges from repeating the same conversations in the same rooms with the same assumptions intact. Letting people hear unfamiliar customer stories, work across different perspectives, or enter new environments can loosen the mental routes they always take. It gives old problems new entrances.

Routine lets the brain move smoothly through the world. Novelty gives it an update.
