Curiosity has been found to be linked to what is known as cognitive reserve — the brain's "safety margin" that helps maintain mental clarity longer in old age. Curious people accumulate more experience that builds this reserve. The results of the study were published in the journal Personality and Individual Differences.
Researchers from the Donders Institute in the Netherlands examined 106 volunteers aged 40 to 85. The scientists measured levels of curiosity and openness to new experiences, as well as key indicators of cognitive reserve — education level and diversity of leisure activities.
It turned out that more curious participants had notably higher cognitive reserve, and this pattern held even after adjusting for age. In other words, curiosity motivates a person to learn, master new skills, and lead a more enriched life — and this, according to current understanding, strengthens the brain and delays age-related decline in memory and thinking.
However, there is an important caveat to the results: higher reserve did not translate into better scores on cognitive tests. This means that curiosity is associated more with the accumulation of "protective" experience rather than with direct improvement of mental abilities in the here and now. Moreover, the sample size was small, and the participants were on average quite intelligent — the mean IQ was 118. Nevertheless, the study supports a simple idea: maintaining a lively interest in the world is beneficial for the brain at any age, as it is a natural way to exercise it.
Cognitive reserve is a concept that explains why, given similar changes in the brain, some people maintain mental clarity while others do not. This "safety margin" is built up through education, complex professional activities, social interaction, and diverse hobbies. Curiosity in this context is not merely a personality trait but a powerful driving force that throughout life propels a person toward learning and new experiences.
