Research around curiosity found that children at age 5 scored 98% on a creativity test. When the same children took the test at age 10, only 30% scored well on the test. By age 15, only 12% of the same children did well. Less than 2% of adults are defined as creative based on their answer to this standardised test.
Science suggests this decrease in curiosity could be caused when we feel there's no gap between what we know and what we want to know, so we just stop being curious.

Children are extremely curious. They keep asking, "why?" and explore new things just because they want to know.
But research shows that during the schooling years, curiosity steadily declines, and as adults, we fall into fixed and convenient thought patterns.
When our curiosity is triggered, we are less likely to fall prey to confirmation bias (looking for information that supports our beliefs rather than for evidence suggesting we are wrong) and to stereotyping people (making broad judgments).
Wonder is said to be a childish emotion. However, as adults, we experience it when gaping at something unexpectedly spectacular.
Adam Smith, an 18th-century moral philosopher, describes wonder as something new and singular that is presented, and memory cannot find any image that nearly resembles this unique appearance.
