When Do “Aha” Moments Occur?

Archimedes, the famous mathematician and inventor during the ancient Greece period, had a problem on his mind. The king of Syracuse at the time, Hiero, told Archimedes that he was suspicious of the goldsmith who forged his new crown. He had a hunch that the goldsmith may have stolen some of the gold and replaced it with silver. The only way to prove it was to melt the new crown, and the king wasn't about to ruin it in case he was wrong!

But Archimedes, a deep thinker, thought about the king's problem a lot. But it wasn't until he was taking a bath that it all clicked.

He noticed that the water he displaced was equal to the weight and volume of his body. Knowing what he already knew combined with this new insight, he felt a sudden sense of uncontrollable glee that he jumped out of the bath tub — naked! — and ran through the city shouting "Eureka! Eureka!" 

The verdict? Both Archimedes and the king were right.

That's why "eureka" (meaning "I have found it! in ancient Greek) became a popular expression when someone experiences an "aha" moment. These "aha" moments are cognitive breakthroughs that seem to come out of nowhere. They feel random, intense, and you feel a sense of glee when everything just suddenly seems to click.

"Aha" moments tend to be an emotional experience that's so powerful, ancient Greece thought these moments of insights were gifts from the gods. 

Imagine if Archimedes was taking a bath while scrolling on his phone. Do you think he would have experienced his famous "aha" moment? My guess is maybe … but mostly likely no. His mind would have been too preoccupied that he might never have recognized what was happening to the water. 

Or what if he was on a Zoom call, focusing on how he looked in the camera, watching everyone's facial expressions, half-listening to the speaker while keeping up with the chat box. Would his "aha" moment have had a chance to catch him in a moment of full presence to feel the sensation?

In a 2025 study, cognitive neuroscientist Maxi Becker and her team devised a lab task to study insight by using Mooney images, which are high-contrast black-and-white pictures that are hard to interpret at first but can suddenly “click” into a recognizable object.

Participants viewed 120 of these images while undergoing fMRI scans, indicating when they recognized an object and rating how "sudden," "positive", and "certain" their experience felt (key qualities associated with moments of insight).

Becker and her team found that successful insight was linked with increased activation in three regions:

These patterns were stronger in experiences and rated as more insightful, suggesting these areas work together to produce the sudden representational change that defines an “aha” moment. 

There are three major elements that, when working together, help develop the right mindset for "aha" moments to thrive in.

Open mindedness is all about being open to different viewpoints, learning something new, and actively listening. You're also being open-minded when you're making time for creativity without goals or pressure to perform.

It's also being open to be proven wrong. If you’re rigidly attached to one interpretation (“I know what this is supposed to be!”), the brain is less likely to reorganize representations. (Something I personally need to work on.) 

I argue that play or "childlike wonder" is just as important as hitting the gym. It's a critical element to learning something new. 

There is nothing wrong with being a novice. In fact, being a novice starts at being open-minded. You're tinkering, trying things, failing, and pushing yourself out of your comfort zone. It's a great place to be! But then you reach a certain point in your learning in which you gain the basic knowledge to solve more complex problems. Knowing the basics of a discipline, skill, or topic is necessary for identifying patterns and relations. 

When I started sewing, I started with the basics: reading the sewing machine manual, learning how to make a straight stitch and a back stitch. Form there, I built the skills and confidence to add a zipper to a project or sew a buttonhole. Just like playing a video game, as I "leveled up" my curiosity grew.

Ever been in a meeting in which someone is presenting complex information and then the presenter asks, "any questions?" and you got nothing? It's mostly because there is a lack of knowledge needed to be curious enough to know what questions to ask.

Basic knowledge is required before reaching a level of curiosity. "Research on curiosity has shown that to have some knowledge radically increases our need for more. If you know nothing about something, you are probably not very curious about it either," says Hilde Ostby, in her book, The Key to Creativity: The Science Behind Ideas and How Daydreaming Can Change the World.*

These three elements: open-mindedness, building basic knowledge, and curiosity work together over and over again in a cycle to bring new insights.

Other brain studies have shown that when a person relaxes with no task to perform or expectations, they are able to rest their mind long enough to make connections and see patterns they may have missed during analytic thinking mode. This is known as the "resting-state brain."

“When I write songs, it’s never a conscious decision. It’s an idea that floats down in front of me at four in the morning or in the middle of a conversation or on a tour bus or in the mall or in an airport bathroom,” says Taylor Swift. “I never know when I’m gonna get an idea and I never know what it’s gonna be.”

Taylor's experience is not uncommon. When we complain, "why do these ideas come to me at the most inconvenient time!?", we can blame it on the "resting-state brain" when we're awakened at two in the morning or taking a long, hot shower. But if you get into a good habit of doing so, one is able to capture that unexpected insight — whether that's writing that thought down, recording a voice memo, or sharing it with someone else right away.

Unfortunately, a "aha" moment might come to your door, but you'll be too distracted to hear it knocking. 

It's all too common now to be constantly bombarded with dings, pings, and news stories, but we have to be intentional about allowing our minds to relax enough for a breakthrough moment to occur. 

"A mind adrift lets our creative juices flow," states Daniel Goleman in his book, Focus: The Hidden Driver of Excellence. "People who are extremely adept at mental tasks that demand cognitive control and a roaring working memory — like solving complex math problems — can struggle with creative insights if they have trouble switching off their full concentrated focus." 

The key is to learn how to toggle between both mindsets: focusing on a problem using analytic thinking, then allowing your brain to rest so it can make new connections that lead to new insights.

Not all "aha" moments are created equal. "Aha" moments can also have downfalls, especially when we're feeling overwhelmed, tired, or burnt out. Feeling overwhelmed can decrease our ability to critical think and we default to easy solutions (even if they're bad) and believing facts (even if they're false).

"The brain processes things that we recognize much faster, and we find comforting. Thinking quickly is comfortable — thinking slowly, not so comfortable," says Rolf Reber, a professor of cognitive psychology at the University of Oslo. 

"Aha" moments come suddenly and it feels great, so you assume it must be right. You still need to put these sudden "aha" moments to the test before believing everything that comes to you, even when you have a strong gut feeling. It might feel great in the moment, but that doesn't equate to it being right.

In today's distracted world that values speed over slow thinking, it's easy to get caught up with the need to figure things out and fast. This is why it can be easy to fall victim of a conspiracy theory, which gives us the same pleasure as a "aha" moment.

To have more "aha" moments, you have to allow yourself to disconnect from distractions and rest your brain. This isn't about optimization or how to configure "aha" moments at an ideal time — that's impossible! There are no shortcuts. But you can do yourself a favor and allow yourself to play, learn, get curious while also allowing your brain to rest and take it slow. 

Then come together with others, share your insights, make connections to create the next big idea. And when that time comes, you'll fully rested and energized to hit the ground running.
