The Latest Brain Science on the Transformative Power of Questions

Whether we're seeking new solutions to problems, strategies for plans, or optimism for crises, new possibilities take us forward. In fact, when we have new possibilities, it's because of how we use language to engage our brain's prefrontal cortex network.

The latest neuroscience reveals that the prefrontal cortex functions as an engagement network. This network constructs everything related to planning, problem-solving, decision making, focusing, responsibility-taking, making new cognitive connections, mindfully noticing differences, running simulations of options, reading the room and acting accordingly, adapting action to new discoveries, overcoming confirmation bias and other logic flaws, creating new options, regulating emotions, moral reasoning, learning new distinctions and abilities, and questioning assumptions. Notably, these are the intrinsic qualities of a curious person.

When we see groups in organizations and communities being productive together, it is precisely because of their engaged curiosity. Groups flounder and fail because of their unquestioned assumptions, which limit their curiosity.

All it takes to disable our engagement functions is to operate from the certainty of unquestioned assumptions. While the language of curiosity is questions, the language of certainty is declarations. The difference between unproductive and productive groups is the structure of their language, resulting in them being more assumption-based or question-based.

From a brain science perspective, assumptions are imagined beliefs about ourselves and our world that we do not question. People who are curious question their assumptions, which means to literally turn them into questions.

When functioning well, the prefrontal cortex network tags assumptions as they emerge, allowing us to turn them into questions. This tagging process relies on complex inhibitory and evaluative circuits that distinguish new information from automatic responses, thereby allowing us to choose more adaptive actions. Productive groups do this naturally, noting and translating assumptions into questions.

On the other hand, when our prefrontal cortex network is disrupted by certainty, assumptions remain untagged, resulting in our operating from them, which further disrupts the performance of this network. As a result, operating from assumptions minimizes prefrontal cortex engagement and all its component functions. This is supported by neuroimaging research, which reveals reduced activation in the prefrontal regions during rigid, habitual, or dogmatic thinking.

Only through questions do we construct new possibilities. If we never learn how to question our assumptions, these networks become disrupted in development, performance, or both. Neuroscience has shown that the process of forming questions and exploring uncertainty stimulates synaptic growth and enhances neural plasticity, resulting in greater cognitive flexibility.

Such disruptions increase dogmatic, authoritarian, and egocentric thinking, which means reduced receptivity to new possibilities. It also leads to emotional dysregulation, manifested as destructive moods and attitudes, which can sabotage performance in life, relationships, learning, and work. Conversely, as our prefrontal cortex develops, we become emotionally regulated, enjoying richer varieties of emotions and stronger emotional recovery, resilience, and repair. Current studies indicate that robust prefrontal regulation is correlated with resilience, empathy, and the ability to recover from stress.

The certainties of dogmatic, authoritarian, and egocentric thinking are natural in child development, roughly between ages 2 and 7 (the preoperational phase). Even though prefrontal cortex development begins around age 7 and completes in our 20s, it is possible for adults of any age to have an undeveloped prefrontal cortex. This is especially true for people whose early developing brains are wired by the brains of others with undeveloped or disrupted prefrontal cortexes.

Interestingly, people with high levels of wealth, status, or education can have well-developed or underdeveloped prefrontal cortices. Whole groups can be dominated by these people; in fact, whole societies can be dominated by them. From a neurological perspective, this means societies or organizations can structurally favor certainty over curiosity, collectively reducing adaptability and innovation.

Fortunately, the construction of open-ended, discovery-focused questions reactivates and repairs these coordination networks, contributing to the development of the prefrontal cortex. Neuroplasticity research affirms that new patterns of thought and inquiry literally rewire the brain, forming new synaptic connections and strengthening existing ones, even well into adulthood.

Curiosity develops and activates the prefrontal cortex networks. This is important because these networks construct new possibilities from our questions. In particular, turning assumptions into questions activates the prefrontal cortex, as well as reward and motivation pathways, and social bonding, fostering more flexible, resilient, and engaged thinking. This, in turn, supports deeper learning, emotional regulation, and collaborative potential. Neurotransmitter systems, such as dopamine, serotonin, and norepinephrine, are intricately involved in motivating engagement, focus, and social connection, thereby amplifying the benefits of curiosity-driven cognition.

This is what's going on in productive groups. Curiosity brings out everyone's best individual and collective thinking, leading to the group thinking and doing together what no one can do alone.

Ultimately, in every moment we choose curiosity over certainty, our brain literally rewires itself for growth. The past is repeated by those who operate from the certainties of their assumptions, while the future belongs to those who turn their assumptions into questions. As brain science demonstrates, fostering curiosity and adaptive questioning not only expands our intellectual horizons but also enhances our well-being, emotional balance, and capacity for meaningful connection throughout life.

This has significant social, political, and organizational implications.

Healthy prefrontal cortex development supports better judgment, emotional regulation, social behavior, and adaptability. Societies that cultivate curiosity from early childhood—through parenting, education, and exposure to diverse experiences—help individuals grow into emotionally regulated, resilient, and open-minded adults.

Societies that encourage questioning, curiosity, and flexible thinking promote mutual understanding and empathy. These qualities help reduce dogmatic, authoritarian, or egocentric behaviors and foster inclusivity and collaboration.

Since prefrontal development enhances self-control and risk assessment, social investments in environments that stimulate prefrontal cortex growth can reduce impulsivity, aggression, and maladaptive behaviors, ultimately strengthening communities.

Neuroscientific research suggests that curiosity and openness can mitigate political biases, enhance receptivity to new evidence, and promote more constructive dialogue—particularly across political divides. Curious individuals are less likely to fall into “echo chambers” and more willing to learn from opposing views.

Political leaders and policymakers with strong curiosity are more likely to consider broad evidence, challenge entrenched assumptions, and create innovative solutions to complex problems.

Societies that promote executive function and curiosity in their citizens are less vulnerable to authoritarianism and dogmatism. Such societies are built on continual questioning, learning, and adaptation.

Organizations that place a premium on and prioritize curiosity in their leaders and teams foster flexible thinking, smarter risk-taking, and greater adaptability. Neuroscience-informed leadership training that builds emotional control, planning, and cognitive flexibility enhances both individual and organizational performance

Workplaces with a culture of questioning and curiosity are more resilient during crises, better at creative problem-solving, and less likely to be derailed by status quo thinking or blind spots. These organizations are also more likely to develop collaborative, growth-oriented teams.

Hiring and designing workplace practices to nurture prefrontal cortex functions helps organizations unlock the potential of diverse talents, improve social dynamics, and maintain a competitive edge in a rapidly changing environment.

Across realms and domains, being question-based becomes the prime strategy for transforming the constant of uncertainty into a renewable, powerful asset. The problems we wrestle with today and hope future generations don't inherit are not intractable. They are unique opportunities for new possibilities that arise from curiosity.
