Openness is a personality trait that means seeking and enjoying new and unfamiliar things. Research in psychology and neuroscience links greater openness with benefits for thinking and mood. People who are more open tend to explore more, learn faster, and generate more ideas. Novel experiences also activate brain systems that support memory and learning. Together, these findings suggest that adding variety to daily life can lift well-being and support mental performance over time.
Openness is partly shaped by genetics, but it can be nudged by habits. A practical starting point is to reset expectations about change. Tastes and interests shift across life, so it is useful to question the idea that “I know what I like” and revisit old dislikes. Next, retry things you think you do not enjoy, such as a food, a genre, or an activity, since your reaction may differ now. Finally, make small, regular choices for curiosity over comfort. List new books, places, or ideas to try, and pick one each week. These steps do not require a major life change, only a gentle push toward novelty.
Openness has limits. Very high novelty seeking can bring risky choices or restless consumption. The aim is a balanced dose of new experiences that fits one’s life. For most people, building a small habit of exploring new places, ideas, and activities is a simple way to support creativity, learning, and long-term brain health.
Nature Neuroscience – Association between real-world experiential diversity and positive affect – 2020
Using GPS tracking, experience sampling, and brain imaging, the study finds that days with more varied locations are linked to higher next-day positive mood, and this link relates to functional connectivity between the hippocampus and striatum, brain regions involved in novelty and reward.
Trends in Neurosciences – Novelty and dopaminergic modulation of memory persistence – 2019
Review of evidence that novel experiences trigger dopamine in the hippocampus, which strengthens memory consolidation. It outlines how different novelty types engage memory systems to enhance learning.
Neurobiology of Aging – Personality traits and cognitive reserve, high openness benefits cognition in the presence of age-related brain changes – 2024
Individuals higher in openness show better cognitive performance even after accounting for brain status, consistent with the idea that openness supports cognitive reserve, the brain’s resilience to age-related changes.
Psychology and Aging – Cognitive engagement and cognitive aging, is openness protective – 2010
In a large longitudinal sample, higher openness is associated with higher cognitive performance across domains throughout later life. The study suggests openness supports better levels of function, even if it does not always slow the rate of decline.

Harvard professor Arthur C. Brooks explains practical ways to increase healthy openness, including resetting expectations, retrying former dislikes, and choosing curiosity over comfort while avoiding novelty for its own sake.
