Listening to a 5 year old who has just started school ask why everyone has to stand in a line before school begins and watching them stop mid-walk to watch a group of ants marching is both inspiring and frightening to many adults who has lost their ability to question the world around them.
By twenty-five years old that same child is more likely to be checking notifications than watching ants or clouds. Somewhere along the passage from childhood to adulthood, that restless tug toward the unknown wanes.
The phenomenon is more than anecdotal. Developmental psychologists have measured a decline in what they call “intellectual curiosity” across the life course. A 2021 study comparing European-American and Chinese-American adults, for instance, found that self-reported curiosity tended to decrease steadily with age (Li et al., Frontiers in Psychology, 2021). The very energy that once defined childhood gives way to a sense of having “enough” answers, or to the fear that asking might reveal ignorance.
Schools play an undeniable role in this slow dimming. In early grades, questions spill freely; one classroom observation study noted that children in kindergarten might ask between 200 and 300 questions a day. By middle school, however, that number drops dramatically, not because the world has grown any less mysterious, but because the institutional machinery of education privileges correctness and efficiency.The irony is stark: the very institutions meant to cultivate knowledge often suppress the disposition to seek it.
But curiosity doesn’t only fade under the pressure of exams. Social norms matter, too. By adolescence, young people are acutely aware of how they appear to others. The once-innocent act of asking “why” risks being judged as naïve. Adults experience a similar inhibition: in workplaces, meetings reward certainty, not wonder.
Cognitive load compounds the problem. As responsibilities grow so does the demand on directed attention. The brain, fatigued by to-do lists and deadlines, has less room for the kind of open-ended noticing on which curiosity thrives. One review of attention research found that mental fatigue directly reduces exploratory thinking and risk-taking (Kaplan, Journal of Environmental Psychology, 1995). This explains why children, unburdened by such demands, are freer to explore.
Perhaps the most overlooked culprit, however, is environmental. In an era of screens and urbanisation, our exposure to nature has been drastically reduced. A child in the UK today spends, on average, less than half the time outdoors that their parents did a generation ago (Natural England, 2016). Nature is not just scenery; it is a living engine of curiosity. Its textures, its unpredictability, its sheer resistance to human control invite questions in a way that digital environments, optimised for efficiency and instant answers, rarely do.
Seen together, these forces amount to a quiet erosion of one of our most vital human capacities. And the consequences are not trivial. To lose curiosity is not just to lose playfulness; it is to weaken one’s resilience to uncertainty and stress.
Yet decline is not destiny. The same research that maps curiosity’s diminishment also points toward ways of rekindling it. Here, nature appears not just as a backdrop but as a remedy. Attention restoration theory, first proposed by Rachel and Stephen Kaplan in the 1980s, suggests that natural environments offer what they call soft fascination and enough stimuli to engage the mind, but gentle enough to allow cognitive recovery. This restoration, in turn, provides the mental resources curiosity requires.
From this vantage point, curiosity is less a trait we grow out of than a muscle we neglect. And nature, with its inexhaustible strangeness, provides the perfect gymnasium.
Rekindling Curiosity Through Nature
If curiosity fades as a by-product of modern life, it can also be nurtured back and the evidence increasingly shows that reconnecting with nature is one of the most powerful ways to do so. The question is not whether wonder can be restored, but how.
1. Practise “wonder walks”
A simple act: walk through a park or woodland not as a commuter but as an explorer. Pause to ask, as a child might, Why do these leaves fall in spirals? What bird makes that call? Psychologists call this “active noticing,” and it’s associated with increased creativity and divergent thinking (Kaufman & Beghetto, Review of General Psychology, 2009). In professional terms, this translates into better problem-solving and the ability to generate novel ideas.
2. Create space for unstructured exploration
Curiosity thrives in the absence of rigid goals. Allowing even short periods of unscheduled time outdoors reduces attentional fatigue and restores the brain’s capacity for complex thought (Kaplan & Kaplan, The Experience of Nature, 1989). Leaders in fields from design to data science describe their best insights arriving not at the desk but during downtime. In this sense, a Saturday afternoon spent wandering in nature is not indulgence, but career training in disguise.
3. Keep a curiosity journal
Journaling observations from nature is not about expertise but practice in question-asking. Research shows that people who habitually generate questions perform better on creative tasks and demonstrate greater intellectual humility (Grossnickle, Educational Psychologist, 2016). Employers increasingly value “learnability” over static knowledge, particularly in rapidly changing sectors like AI and biotechnology. A curiosity journal is one way to cultivate that learnability.
4. Foster cultures of safe questioning
Just as nature tolerates imperfection so too must our social environments if curiosity is to flourish. Creating group walks, outdoor workshops, or even “question circles” during hikes normalises uncertainty and makes space for naïve questions. Research in organisational psychology suggests that “psychological safety” is a key driver of team innovation (Edmondson, Administrative Science Quarterly, 1999). Translating this into the workplace, employees encouraged to wonder aloud are more likely to find creative solutions.
Why Careers Need Childlike Curiosity
In an age of automation, curiosity is more than a personal luxury; it is an economic necessity. The World Economic Forum’s Future of Jobs Report (2020) ranks creativity, resilience, and adaptability among the top ten skills for the next decade. These capacities are not by-products of rote knowledge but of curiosity: the willingness to question assumptions, explore alternatives, and embrace ambiguity.
Employers increasingly recognise this. A survey by LinkedIn Learning (2019) found that 74% of talent developers and hiring managers rated “a growth mindset” as more important than technical skills. Similarly, McKinsey reports that organisations with cultures of continuous learning and questioning outperform competitors in innovation metrics.
Childlike curiosity, then, is not a sentimental indulgence but a strategic advantage. The child who once chased dragonflies, if they relearn that habit as an adult, becomes the professional who notices overlooked patterns in climate data, who imagines novel solutions in architecture, who asks questions that others consider too naïve but turn out to be profound.
The Call Back to Wonder
Nature, with its fractal patterns and unpredictable rhythms, is not only medicine for the weary mind but a training ground for the skills our future demands. To ask “why?” at the sight of a bird or a leaf may seem trivial. In fact, it is practice. Practice in seeing the world afresh, in admitting ignorance, in connecting dots others overlook.
