Openness to experience is one of the five major dimensions of personality identified by psychologists, and it captures how much a person is drawn to novelty, imagination, aesthetic experiences, and unconventional ideas. Researchers define it as reflecting cognitive engagement with perception, fantasy, aesthetics, and emotions, distinguishing it from the other four traits (conscientiousness, extraversion, agreeableness, and neuroticism) by its emphasis on the inner life of ideas and sensory experience.1PubMed Central. Openness to Experience and Intellect Differentially Predict Creative Achievement in the Arts and Sciences Someone high in openness tends to seek out varied experiences, appreciate art and beauty, entertain abstract thinking, and question conventional wisdom. Someone low in openness tends to prefer familiarity, routine, and concrete thinking. But the trait turns out to be more internally complex than that simple sketch suggests, and its effects reach into corners of life you might not expect.
What the Six Facets Actually Measure
Openness is not a single, uniform quality. Factor analyses of dozens of personality scales consistently break it into six facets that cluster together statistically but describe quite different tendencies.2Imagination, Cognition and Personality. Openness to Experience as a Basic Dimension of Personality In the most widely used model, those facets are:
- Fantasy: a tendency toward vivid imagination and a rich inner life, daydreaming readily and elaborating mental scenarios.
- Aesthetics: a strong responsiveness to art, music, poetry, and beauty in the environment.
- Feelings: receptivity to one’s own emotional states, both positive and negative, and a willingness to experience them fully.
- Actions: a preference for novelty and variety in activities, willingness to try unfamiliar foods, visit new places, or break out of routines.
- Ideas: intellectual curiosity, enjoyment of philosophical arguments, puzzles, and abstract thinking.
- Values: readiness to re-examine social, political, and religious values rather than accepting them as given.
A person can score high on some facets and low on others. You might love abstract philosophy (high Ideas) but feel indifferent toward visual art (low Aesthetics), or be deeply moved by music (high Aesthetics) but prefer sticking to a familiar weekly schedule (low Actions). This internal variability matters because the facets predict different outcomes. Research on the relationship between openness facets and political ideology, for instance, found that Fantasy and Actions were the strongest correlates, while Aesthetics and Feelings were weaker predictors, and Ideas showed inconsistent links across samples.3Personality and Individual Differences. The relationship between Openness to Experience and political ideology Treating openness as a single number washes out these differences.
An independent factor analysis of 36 existing openness-related scales identified a slightly different set of six facets: intellectual efficiency, ingenuity, curiosity, aesthetics, tolerance, and depth.4PubMed. Openness to Experience: its lower level structure, measurement, and cross-cultural equivalence The labels shift depending on which research team is doing the carving, but the underlying pattern is stable: openness spans both a “thinking” side and a “sensing and feeling” side, and researchers increasingly treat those two sides as distinct aspects of the broader trait.
Openness Versus Intellect
The most consequential structural finding about openness in recent decades is that it splits into two broad aspects, not just six narrow facets. These aspects are typically called Openness (in the narrow sense) and Intellect. Openness in this narrower usage reflects engagement with fantasy, perception, and aesthetics, while Intellect reflects perceived intelligence and intellectual engagement.5PubMed Central. Structural correlates of Openness and Intellect: Implications for the contribution of personality to creativity They share enough variance to belong under the same umbrella, but they pull in different directions when you look at what they predict in people’s lives.
A set of three studies with a combined sample of nearly 900 adults illustrated the split clearly. The Openness aspect predicted artistic interests, aesthetic life goals, and universalism values. The Intellect aspect predicted none of those things in any of the three samples.6Personality and Individual Differences. Openness and Intellect: An analysis of the motivational constructs underlying two aspects of personality This is a striking divergence for two things that are supposed to be parts of the same trait. In practical terms, knowing whether someone scores high on the aesthetic-experiential side or the intellectual-engagement side tells you very different things about what they value and pursue.
A network analysis of four major openness inventories reinforced this two-aspect structure and added a third candidate: open-mindedness, reflecting tolerance and nontraditionalism. The analysis identified ten distinct facets at the fine-grained level, clustering under the familiar intellect and experiencing (openness) aspects, plus this third grouping.7PubMed. Reopening Openness to Experience: A Network Analysis of Four Openness to Experience Inventories Whether open-mindedness eventually becomes established as a true third aspect or gets absorbed back into one of the other two is still an open question, but the intellect-versus-openness distinction has become a standard tool in personality research.
The Dopamine Connection
A natural question about any personality trait is what is happening in the brain to produce it. For openness, the evidence points consistently toward the neurotransmitter dopamine, particularly in prefrontal brain circuits involved in exploration and cognitive flexibility. Research has confirmed that genes involved in prefrontal dopaminergic function, specifically COMT and DRD4, are associated with openness/intellect scores. These findings support the broader theory that dopamine drives the cognitive exploration that characterizes the trait.8Journal of Research in Personality. Sources of cognitive exploration: Genetic variation in the prefrontal dopamine system predicts Openness/Intellect
The dopamine link gets more interesting when you look at creativity. One experiment used sulpiride, a drug that blocks certain dopamine receptors, to test how dopamine modulation interacts with openness. People who were already high in openness actually showed their highest divergent-thinking scores under the dopamine blocker, while the drug made little difference for less open individuals.9PubMed Central. Openness to experience predicts dopamine effects on divergent thinking This counterintuitive finding suggests that highly open people may already have elevated baseline dopamine activity in exploration-relevant circuits, so the blocker brought them into an optimal range rather than impairing them. The relationship between dopamine and openness is not simply “more dopamine, more open.” It’s more like openness reflects a particular tuning of the dopamine system, and that tuning interacts with context in complex ways.
Beyond dopamine specifically, the variability in openness across individuals appears to be influenced by a mix of environmental factors, genetic factors, and differences in both functional and structural brain connectivity.10PubMed Central. The neurobiology of openness as a personality trait Twin and family studies show that personality traits in general are moderately heritable, with the genetic architecture being highly polygenic, meaning hundreds or thousands of small genetic effects contribute rather than any single “openness gene.”11PubMed Central. The genetics of human personality
Openness and Intelligence
People sometimes assume openness is just another word for being smart. It’s not, but the two are related in specific and somewhat surprising ways. The facets that make up openness are only weakly and inconsistently correlated with psychometric measures of intelligence.12Imagination, Cognition and Personality. Openness to Experience as a Basic Dimension of Personality However, when you look more carefully at which kind of intelligence, the picture sharpens.
Openness correlates much more strongly with verbal and crystallized intelligence (the accumulated knowledge and vocabulary a person builds over a lifetime) than with executive functioning or fluency tasks. In one neuropsychological study, the correlation between openness and crystallized intelligence was 0.44, compared to just 0.16 for executive functioning.13PubMed Central. A Neuropsychological Study of Personality: Trait Openness in Relation to Intelligence, Fluency, and Executive Functioning Even more interesting, that correlation grew stronger with age, rising to 0.53 among elderly adults. The researchers interpreted this as evidence that openness is more about a lifelong habit of acquiring broad verbal and intellectual skills than about raw processing speed or any specific cognitive ability.
The openness-versus-intellect distinction matters here too. When the two aspects are separated, the Intellect aspect independently predicts general intelligence, with roughly equal links to verbal and nonverbal ability. The Openness aspect, by contrast, is independently associated only with verbal intelligence.14PubMed. Openness to experience, intellect, and cognitive ability This fits the broader pattern: the “thinking” side of the trait connects to cognitive horsepower, while the “experiencing” side connects more to what you do with that horsepower over a lifetime of reading, conversation, and cultural engagement.
How Openness Shapes Creativity
Of all the personality traits, openness is the most reliable predictor of creative achievement. This has been confirmed across multiple study designs, but the brain-level explanation adds detail that the personality-questionnaire studies alone cannot. Structural equation modeling has shown that both openness and divergent thinking (the ability to generate many different solutions to an open-ended problem) independently predict creative achievement. Brain imaging reveals that both are correlated with connectivity in the attention network and the default mode network, the regions active during mind-wandering and idea generation. But openness also involves the primary sensorimotor network and the frontoparietal control network, suggesting it taps into a wider range of neural resources than divergent thinking alone.15PubMed. The functional connectivity basis of creative achievement linked with openness to experience and divergent thinking
One implication is that openness does not simply make you “better at brainstorming.” It seems to broaden the perceptual and attentional landscape, pulling in more sensory detail and more cross-domain associations. That may explain why highly open people tend to notice connections between seemingly unrelated ideas and why they gravitate toward artistic and intellectual pursuits that reward that kind of wide-net perception. This connects back to the trait called absorption, a tendency toward deep immersion in sensory and imaginative experience, which is closely related to openness and appears to intensify both inner and outer sensory experience.
Changes Across the Lifespan
Openness is not fixed at birth. Two large national samples found a fairly linear pattern of age differences: younger adults in their late teens and twenties scored the highest, with scores declining steadily into old age, a difference the researchers characterized as medium to large.16PubMed Central. Age Differences in the Big Five Across the Life Span: Evidence from Two National Samples But those are cross-sectional snapshots. Longitudinal data, which follows the same people over time, paints a slightly different picture: openness tends to remain relatively stable in emerging adulthood before declining in midlife and old age.17PubMed. Openness to experience and culture-openness transactions across the lifespan
The longitudinal research also found that individual differences in openness trajectories were significant. Not everyone declines at the same rate, and changes in openness were correlated with changes in cultural activity. People who kept attending concerts, reading widely, or engaging with new art forms showed smaller declines. This raises a chicken-and-egg question: does staying culturally engaged keep you open, or does remaining open keep you culturally engaged? The honest answer is probably both, in a reinforcing loop. If you stop seeking out new experiences, your openness has less fuel. If your openness dips, you are less motivated to seek novelty. Either way, it is not a trait you can simply take for granted as you age.
Political Attitudes and Values
Openness is the personality trait most consistently linked to political orientation. Higher openness predicts more liberal ideology, while higher conscientiousness predicts more conservative ideology.18PubMed Central. Personality, Childhood Experience, and Political Ideology This association has been replicated across many samples in Western countries, though its strength varies. In Belgian and student samples, the negative correlation between openness and right-wing ideology was significant and moderately strong. In a Polish sample, the relationship was weaker. In a political party sample, it failed to replicate entirely.19Personality and Individual Differences. The relationship between Openness to Experience and political ideology
The link is also more robust for cultural or social conservatism than for economic conservatism. Research on openness and “boundaries in the mind” found weak relationships between openness and economic conservative beliefs, suggesting that the trait connects more to attitudes about tradition, authority, and social norms than to views about markets and fiscal policy.20PubMed. Openness to experience and boundaries in the mind: relationships with cultural and economic conservative beliefs This makes sense given what the facets measure: someone who scores high on Values (readiness to question received norms) and Actions (preference for novelty) would naturally gravitate toward less traditional political positions, regardless of their views on tax rates.
Career Outcomes
If openness sounds like an unambiguously good thing to have, the career data introduce some useful nuance. Openness predicts upward job changes into managerial and professional positions, and interestingly, achieving those positions then feeds back to produce further increases in openness, creating a reciprocal dynamic between the trait and the career environment.21PubMed Central. Openness to experience as a predictor and outcome of upward job changes into managerial and professional positions That is the upside.
The downside is that openness has been found to be negatively related to salary level.22Journal of Vocational Behavior. The Five-Factor Model of Personality and Career Success This seems paradoxical until you consider what highly open people tend to optimize for. They may choose work that is intellectually stimulating, artistically fulfilling, or values-aligned over work that maximizes earnings. They may also be more willing to switch directions entirely when their curiosity leads them somewhere new, which can disrupt the steady accumulation of seniority and salary that comes from staying in one lane. In other words, openness helps you get promoted but may not help you get rich, because the trait pulls people toward intrinsic rewards rather than extrinsic ones.
Openness and Mental Health
The relationship between openness and psychopathology is more tangled than for most personality traits. The overall association between openness/intellect and psychotic-spectrum traits like schizotypal personality symptoms is weak. But that weak overall number hides strong associations in opposing directions when the two aspects are separated. Unique variance specific to different conceptualizations of openness shows much stronger links, often pulling toward and away from psychoticism simultaneously.23PubMed. Openness to experience, intellect, schizotypal personality disorder, and psychoticism: resolving the controversy
The gist is that certain aspects of openness, particularly vivid fantasy life and unusual perceptual experiences, overlap meaningfully with the positive symptoms of schizotypy (odd beliefs, magical thinking, perceptual aberrations). But the intellectual engagement side of the trait may actually be protective, providing cognitive frameworks that keep unusual experiences from becoming disorganized or distressing. This is why blanket statements like “openness is linked to psychosis” or “openness protects mental health” both miss the mark. The answer depends entirely on which facets you are talking about and what you are comparing them against.
Does Openness Exist in Other Cultures and Other Species
A fair objection to any personality trait is whether it reflects something universal about human psychology or just the tendencies of the Western, educated populations where most personality research has been conducted. The cross-cultural evidence for openness is a mixed but generally positive story. When the Chinese Personality Assessment Inventory was originally developed, it did not include an Openness factor. Researchers later generated six culturally relevant Openness scales and administered them alongside the Western NEO-FFI to over a thousand Chinese college students. Joint factor analyses showed that four of the new culturally grounded openness scales loaded with the Openness factor of the Western inventory.24Journal of Cross-Cultural Psychology. Relevance of Openness as a Personality Dimension in Chinese Culture The trait exists in Chinese culture, but it needed culture-specific items to measure it properly, which suggests that while the broad tendency toward novelty-seeking and aesthetic sensitivity is universal, the specific ways it manifests vary by cultural context.
The comparative animal literature is even more striking. A review of 19 personality studies across 12 nonhuman species found that extraversion, neuroticism, and agreeableness showed the strongest cross-species generality, followed by openness. A separate conscientiousness dimension appeared only in chimpanzees.25Current Directions in Psychological Science. Personality Dimensions in Nonhuman Animals The fact that something resembling openness shows up in species as different as octopuses, dogs, and great apes suggests it is not just a cultural artifact. At a deep level, variation in exploratory behavior versus neophobia (fear of novelty) appears to be a fundamental axis along which animals differ, and openness may be the human elaboration of that axis.
Can You Deliberately Increase Your Openness
Personality traits are moderately stable but not immutable, and recent intervention research has tested whether people can deliberately shift their openness levels. A smartphone-based intervention study gave participants daily behavioral challenges designed to increase openness to action over two weeks. Participants who chose the openness-to-action intervention showed greater increases in that facet compared to a control group, and the changes were maintained at follow-up assessments two and six weeks after the intervention ended.26European Journal of Personality. Becoming More Conscientious or More Open to Experience? Effects of a Two–Week Smartphone–Based Intervention for Personality Change
The effects were modest and targeted one specific facet rather than the broad trait, but the principle is encouraging: small, sustained changes in behavior can shift personality scores in measurable ways. This aligns with the lifespan finding that changes in cultural activity track with changes in openness. The trait is not purely a genetic endowment you are stuck with. It responds to what you do, though it is not infinitely malleable either. Think of it less like eye color (fixed) and more like physical fitness (partially inherited, substantially influenced by habits, and responsive to effort in both directions).
How Openness Shows Up in Digital Behavior
An emerging line of research examines whether personality traits, including openness, can be predicted from digital behavior. Analysis of social media expression has shown that language use, topic preferences, and posting patterns carry detectable personality signals. Prediction models for personality traits built from social media data achieved cross-validated correlations ranging from 0.44 to 0.48 across the five personality dimensions.27PubMed Central. How social media expression can reveal personality Those correlations are moderate but meaningful, roughly in the same range as the correlations between openness and crystallized intelligence discussed earlier. What people share, how they phrase things, and what topics they engage with online collectively form a detectable fingerprint of their openness level, even without their taking a formal personality questionnaire.
The practical significance is double-edged. On the research side, digital footprints allow personality science to move beyond self-report questionnaires, which have well-known limitations like social desirability bias. On the privacy side, the ability to infer someone’s personality from their online behavior raises obvious concerns, especially when combined with targeted advertising or political messaging. Openness, given its association with political attitudes and values, is one of the traits most amenable to this kind of targeted influence. That possibility has moved from speculative to real in the past decade, and it is worth being aware of if you spend time producing public content online.
