A drawing of a hat that is not a hat exposes a fault line between children and adults long before any therapist enters the scene. In The Little Prince, adults fail to see an elephant inside a boa constrictor, and that blindness is not just a literary joke; it maps neatly onto what personality psychology calls a decline in openness to experience and a shrinking bandwidth for curiosity.
Research on trait curiosity and the Big Five model shows that many adults do not simply gain emotional regulation or a stronger prefrontal cortex; they also accept a narrower prediction model of the world. The businessman who obsessively counts stars and the geographer who never leaves his desk embody a kind of cognitive entropy reduction: they trade exploratory behavior for efficiency and social reward. Laboratory scales that measure epistemic curiosity and sensation seeking register exactly this drift from exploration toward control, even in people who would describe the shift as becoming responsible or realistic.
The book’s parade of adults can be read as case studies in declining marginal utility of new experience. Once social roles and status rewards are in place, the brain’s reward circuitry favors confirmation over discovery. The Little Prince, by contrast, treats questions as an end in themselves, not as a tool for optimization. The story quietly suggests that what is often labeled maturity is closer to a reallocation of cognitive resources away from playful hypothesis testing and toward stability maintenance, leaving wonder as collateral damage.
