“How could you,” began George Mackey, a Harvard professor.

“How could you, a mathematician, a man devoted to reason and logical proof. How could you believe that extraterrestrials are sending you messages? How could you believe that you are being recruited by aliens from outer space to save the world? How could you…?”

Nash looked up at Mackey, with an unblinking stare as cool and dispassionate.

“Because.”

Nash said slowly in his soft, reasonable southern drawl, as if he is talking to himself.

“The ideas I had about supernatural beings came to me the same way that my mathematical ideas did.”

John Nash, a Nobel prize winning mathematician, who lived in schizophrenia (a form of psychosis notable for the presence of hallucinations and delusions – that causes a person to see things that aren’t there), provides a nuanced portrayal of creativity. The 2001 film ‘A Beautiful Mind’ shows Nash’s genius stems not from conventional intelligence alone but from his ability to see patterns where others do not, and to obsessively pursue original ideas. His development of game theory – a breakthrough in economics and strategy – reflects the power of focused, independent thought. The film also highlights the fine line between genius and madness. Nash’s hallucinations and delusions, products of paranoid schizophrenia, emerge from the same brain that produces world-changing insights.

The Thought Process of a Creative Mind

At the core of creativity lies a unique way of thinking: one that is fluid, associative, and flexible. A creative mind does not simply seek correct answers – it explores possibilities. Where a conventional thinker might aim for efficiency and accuracy, a creative thinker is comfortable with ambiguity and novelty.

The creative process often begins with a problem or question, followed by an incubation period where the mind subconsciously explores solutions. Insights can seem sudden, but they are usually the result of extensive mental groundwork. This “eureka” moment is when the brain forms unexpected connections between disparate ideas, drawing from past knowledge, emotions, and sensory experiences.

But where do these ideas come from…?

Let’s understand the dopamine first – the root of creativity.

As we read earlier, dopamine is a neurotransmitter associated with reward, motivation, and learning, it isn’t about pleasure, but it delivers a feeling much more influential. It’s a reaction to the unexpected – to possibility and anticipation.

Our brains segment the external world based on proximity and interaction:
1. Near (Peripersonal): The space of immediate reach and control, representing present reality.

2. Far (Extrapersonal): The space beyond direct physical interaction, representing potential and possibilities.

We constantly make predictions about what’s coming next. With the pursuit of better things, we keep on maximizing resources that will be available to us in the future. We constantly anticipate the future. Dopamine is released not just by rewards, but by positive surprises that, quite often, violate our predictions. When reality is better than expected – there is positive prediction error that triggers dopamine.

Dopamine only purpose is to maximize future rewards. It fuels our motivation & brightens our imagination. It can never be satisfied. Dopamine can only say “more”.

Dopamine is released when the brain detects something novel, surprising, or potentially rewarding. It acts as a “relevance signal” helping the brain figure out what’s worth noticing, remembering, or pursuing.

Relevance signal (or Salience) – the core of how the brain decides what to pay attention to and what is important. Our brains constantly filter a vast amount of sensory and cognitive input, and salience helps determine what gets prioritized for further processing, action, or memory.

Things are salient when they are important to you, if they have potential to impact your well-being, for good or for evil, if they have the potential to affect your future. Things are salient if they trigger desire dopamine.

They broadcast the message, “Wake up. Pay attention. Get excited. This is important.”

Normally, the brain filters familiar or unimportant information, so we’re not overwhelmed. This filtering process is called latent inhibition. When this filtering is weak (i.e. low), more information enters conscious awareness, increasing mental load but also potentially boosting creativity.

Low latent inhibition is a cognitive trait where a person has reduced ability to filter out irrelevant stimuli from their environment. In other words, people with low latent inhibition notice more details – sights, sounds, smells, thoughts – that most others would automatically ignore or tune out.

Dopamine plays a key role in both low latent inhibition and salience attribution. Many highly creative individuals – artists, inventors, writers – are thought to have low latent inhibition, as it allows them to notice and combine subtle details in unique ways. They may see connections others miss because they process more raw material. Conversely, those who can’t manage the overload may experience sensory overwhelm, anxiety, or psychosis. In certain mental health conditions like schizophrenia, the salience system may misfire, causing dopamine to incorrectly tag irrelevant stimuli as important, which can contribute to delusions or hallucinations.

Dopamine regulates both processes, influencing whether we’re overwhelmed or inspired by what we perceive. By doing so, it influences what we notice, what captures our imagination, and what drives our behavior. This mechanism is key to both creative insight and mental stability.

How the Creative Mind Evolves

Let’s understand the mental models first – our internal, simplified versions of reality.

To make sense of the world, we create internal, imaginary representations called mental models. Much like the filtering process of latent inhibition, these models contain only the elements the brain considers critical, ignoring extraneous details. This makes the environment more comprehensible and allows us to mentally rehearse manipulating it for desired outcomes. The brain automatically constructs and refines these models continuously based on new information. Beyond simplifying our understanding, models facilitate abstraction, enabling us to derive general principles from specific encounters. This crucial ability empowers us to predict and effectively handle novel circumstances.

Choosing between options is significantly aided by our mental models. These internal representations allow us to engage in ‘mental time travel,’ running through different imagined future scenarios. Through this imaginative projection, we can mentally experience various possibilities and strategize how to best leverage resources and outcomes. This powerful dopamine-driven capability is critical for planning and executing every future action we take.

Path to Creativity starts with breaking models

Models are powerful tools, yet they pose a challenge: they can restrict our thinking, leading us to miss opportunities for positive change. They can rigidify our thinking, potentially causing us to overlook opportunities for improvement.

To invent something new, creative people must first break free from these models. Fascinatingly, dopamine facilitates this duality – it helps build the models we rely on, and also drives the impulse to break them apart. Both creation and deconstruction involve envisioning possibilities beyond current reality. This intense focus on future possibility characterizes creative genius. Such individuals are often so absorbed in their internal landscape of ideas – exploring the unknown and the not-yet-discovered realm – driven by an obsession to make the future a better place through their work, that they may inadvertently neglect the immediate, everyday realities and needs of others.

Neuroscientific studies reveal that creativity involves the interaction between different brain networks – notably, the default mode network (involved in imagination and daydreaming), the executive control network (responsible for focus and judgment), and the salience network (which switches between the two). This dynamic interplay allows the brain to both generate and refine ideas.

Is Creativity Inborn or Built?

Research suggests that some individuals are born with traits that favor creative thinking, such as high openness, strong memory, or unusual sensitivity. However, creativity is not fixed – it can be cultivated. Creativity is also domain specific. A person may be highly creative in music but average in mathematics, or vice versa. What matters is consistent effort, curiosity, and the willingness to explore beyond the obvious.

“A Beautiful Mind” movie offers several powerful lessons about creativity, particularly through the life and mind of mathematician John Nash, whose story is a blend of genius, mental illness, and profound intellectual discovery. Here are 3 key lessons on creativity from the film:

a) Creativity Often Emerges from Obsession and Deep Focus: Nash’s breakthrough in game theory comes not from surface-level thinking but from years of intense focus, showing that creativity often requires persistence, obsession, and a deep desire to solve complex problems.

b) Seeing Patterns Where Others Don’t: Nash sees patterns in everything – newspapers, movements, social behaviors – even when those perceptions become delusional. This reflects a key creative trait: the ability to connect unrelated things in meaningful ways.

c) The Line Between Genius and Madness Is Thin: The film shows Nash’s descent into paranoid schizophrenia, blurring reality and delusion. It suggests that the same cognitive openness that allows creativity can also make someone more vulnerable to mental instability.

Is Creativity just about Dopamine?

Dopamine-producing cells account for only 0.0005% of the brain’s total cell count—a minute fraction when considering the vast number involved in simply navigating our environment. Yet, when we reflect on our identity at its deepest level, this tiny cluster of cells seems disproportionately significant. We feel a profound connection to dopamine’s influence, leading us to identify strongly with it, almost perceiving ourselves as embodying its function.

What is the essence of humanity? Perspectives differ, yet all point to dopamine’s influence:

• For the Academic: It’s comprehension – rising above senses to understand meaning, involving evaluation, judgment, and prediction (driven by dopamine).
• For the Hedonist: It’s the experience of pleasure – maximizing life’s rewards through pursuits like art and social connection (powered by dopamine).
• For the Artist: It’s the power to create – manifesting novel beauty and truth from within (a process linked to dopamine).
• For the Spiritual: It’s transcendence – connecting with the soul in imagination, beyond the physical (accessed via dopamine).

What constitutes the essence of being human is our free will, allowing us to choose our path rather than being solely governed by instincts or reacting automatically to our surroundings.
