You are overthinking.

You are a superhuman.

Both things are true at the same time.

Overthinking is your mind processing fast

Your thinking is doing real work. Each time you return to a situation, something gets more specific. A truer word arrives. A next step comes into focus.

This is the kind of thinking that delivers your best decisions, often hours or days later.

There is another version of overthinking that gets stuck and goes nowhere. That kind needs its own response and its own conversation. This piece is not about that one.

This piece is about the version most leaders have been mistaking for a flaw.

The science of why intelligent minds overthink

If you suspect you might be overthinking because something is wrong with you, the research disagrees.

Researchers at SUNY Downstate Medical Center scanned the brains of people across the IQ spectrum. The higher the IQ, the more activity in the regions associated with worry and rumination.

In other words, the more your mind turns things over, the more likely it is to be a high-functioning one.

A study published in Personality and Individual Differences with 126 participants confirmed it from another angle. Verbal intelligence was a positive predictor of worry and rumination. The more verbally intelligent the person, the more they returned to past and future events, examining them.

This is the experience of being you, on a Tuesday night, replaying the meeting that already ended. The brain is not malfunctioning. It is doing what intelligent brains have been measured doing in study after study.

And then comes the finding that changes everything.

The Colorado Longitudinal Twin Study, published in 2020 with 751 participants, split rumination into two kinds. Brooding, which is repetitive negative thought that goes nowhere. And reflective pondering, which is deliberate thinking through an experience to understand it better.

Reflective pondering was positively associated with every measure of intelligence the researchers tested. Brooding was not.

The science is telling you the same thing I have been telling you. There are two kinds of overthinking, and one of them is a marker of high cognitive ability.

What your brain is actually doing

So what is happening in there?

In 2018, researchers at VU University Amsterdam published a study in eLife on what makes some brains capable of holding more at once. They looked at brain cells from people across the IQ spectrum. The cells in higher-IQ individuals were faster, larger, and better connected. They handled more incoming information at the same time, and they passed it along more efficiently.

Some brains are simply built to take in more streams of information in parallel, hold them longer, and turn them into something useful faster than other brains.

This is not a metaphor. It is how your brain works at the cellular level.

Why fast thinkers take longer on the hard ones

Faster cells do not always mean faster decisions. The research has a surprise on this front, and it explains a particular kind of frustration most overthinkers know well.

A 2023 study at the Berlin Institute of Health and Charite ran personalized brain simulations of 650 people from the Human Connectome Project. The researchers expected higher-IQ participants to be faster across the board.

They were faster on simple tasks. On complex problems, they took longer than people with lower scores. They also made fewer errors.

Higher-IQ brains were better connected internally, and that connection allowed them to hold off on decisions longer. Lower-scoring brains jumped to conclusions. The high-performing brains turned the problem over more times before they committed.

That is what overthinking looks like under an MRI. The brain refusing to settle for the first acceptable answer.

If you have ever been told you take too long to decide, the people telling you that are jumping.

The reason your best ideas come hours later

Holding off on a decision does not mean the brain stops working on it. Quite the opposite.

In 1926, the British psychologist Graham Wallas described a four-stage model of creative problem solving. Preparation, incubation, illumination, verification. Incubation is the stage where you set the problem aside and your unconscious mind keeps working on it. Wallas drew much of his model from the mathematician Henri Poincare, who described complex mathematical breakthroughs arriving suddenly after periods of rest or distraction.

Almost a hundred years later, the science holds. A meta-analytic review by Sio and Ormerod found that 29 out of 39 experiments showed a significant incubation effect. People given a break from a problem outperformed people who worked on it continuously.

Returning to a thought, again and again, with breaks in between, is one of the most reliable creative methods we have ever measured.

It is also exactly what you have been calling overthinking.

Your mind is not running in a straight line

If your unconscious is working on the problem while you are doing the dishes, what else is it doing in the background?

Almost everything.

The old model of thinking assumed one thought at a time. Modern neuroscience has dismantled that view.

Your brain runs many tracks at once. While you are consciously thinking about a meeting tomorrow, the rest of your mind is working in the background on a problem from last week, an emotion from this morning, a pattern you noticed in your team three days ago. All of it. At the same time.

Psychologists describe this as two systems running together. A fast system that works underneath, in parallel, automatically. And a slower system that works one thing at a time, on the surface, where you can feel it.

Most of what you call thinking is the slow surface. Most of the actual work is happening underneath.

Your overthinking is the moment you become aware of a mind that has been running in parallel since you were a child.

Why your mind keeps running, even at 3am

Now consider what you are asking that parallel mind to handle in a typical day.

A market shift, three Slack channels, two crises on different continents, your team’s energy, your kid’s school email, a podcast at 1.5x speed, a thread you opened on the way to a meeting. Before 10am.

Your nervous system has been training on inputs like this for years. Parallel streams. Constant signal. Switching between contexts at speeds the modern world made normal.

Of course your mind keeps running after the inputs slow down.

This is also why you wake at 3am with your mind moving. The processing does not stop just because you are unconscious.

Sleep researchers have known for decades that the brain replays the day in your absence. It links new information to old. It consolidates memory. It solves problems your waking mind could not crack. People are nearly three times more likely to find a solution after sleep than after the same hours awake.

The traditions I trust describe the window between three and four in the morning as porous. The body still. The conscious mind offline. The system free to do its deeper work without interference. Old patterns surface to be released. New understanding lands.

Two languages. The same phenomenon.

Your mind kept running because it was still processing what the day asked it to hold. That is the same superhuman quality showing up at a different hour.

A different relationship with your own mind

Once you understand all of this, the relationship with your own thinking changes.

The leaders I work with who navigate this era well have stopped fighting their own minds. When the thinking keeps moving, they let it. They trust that the metabolism is working, even when it is uncomfortable, even when the answer takes its time to arrive.

They have built two muscles instead of one. The receiving muscle, which you already have, the one that takes in more than the people around you. And the releasing muscle, which most leaders have never been taught to build, the one that lets the day’s intake actually move through. Movement. Breath. Sleep. A conversation with a coach or therapist who knows how to work with a mind like yours.

Once both are working, the same depth that has been exhausting you becomes the thing that makes you impossible to replace.

Your overthinking is one of the most underused intelligences you have.

The work now is to recognize it when it shows up, trust it when it does, and build the release that lets it do what it was always built to do.

That is how a superhuman starts using the gift she was already given.
