Does Your Personality Type Predict Whether You’ll Be Single? What the Big Five Research Shows
Does your personality type predict whether you’ll be single? The honest answer from the research is yes — but only modestly, and mostly through traits you carry steadily rather than your day-to-day mood. A 2026 study published in the Journal of Personality, using Germany’s Pairfam longitudinal panel, found that higher Openness was linked to greater odds of being single (especially among women), while higher Conscientiousness, Extraversion, and Agreeableness each lowered those odds. A separate 2024 study of more than 77,000 Europeans aged 50 and older found that people who had never partnered scored lower on Extraversion, Conscientiousness, and Openness than those who had been in relationships. None of this means a test result decides your love life. It means your standing on the Big Five shapes how you meet, attract, and keep partners — and that is genuinely useful to know.
What researchers mean by the “Big Five”
The Big Five, also called the Five Factor Model or the OCEAN model, is the most widely used framework for describing personality dimensions. Instead of sorting people into types, it scores everyone on five broad, continuous traits:
- Openness to Experience — curiosity, imagination, and a taste for novelty, ideas, and unconventional paths.
- Conscientiousness — self-discipline, organization, and a drive to set and achieve goals.
- Extraversion — sociability, energy, and a need for external stimulation and connection.
- Agreeableness — compassion, cooperation, and concern for social harmony.
- Neuroticism — the tendency to feel negative emotions such as anxiety, irritability, or mood swings.
Your position on these five dimensions is relatively stable in adulthood, which is exactly why researchers can study how it tracks long-term outcomes like relationship status.
What the 2026 longitudinal study found
The clearest modern evidence comes from a 2026 paper in the Journal of Personality by Apostolou, Kislev, and Anagnostopoulos, built on the Pairfam longitudinal study in Germany. By statistically separating each person’s stable trait level from short-term fluctuations, the authors showed that personality predicts singlehood mainly through enduring dispositions, not momentary states. Here is how each trait behaved.
Openness — the trait tied to higher odds of being single
Higher Openness was associated with greater odds of being single, and the link was stronger for women. People high in Openness often prioritize autonomy, varied experiences, and unconventional life paths over scripted milestones like early marriage.
Openness appears to pull some people toward independent, less scripted lives — which can mean fewer social pressures to couple up.
Conscientiousness, Extraversion, and Agreeableness — the “coupling” traits
Each of these three traits was linked to lower odds of being single. Conscientious people bring reliability and follow-through; extraverts have larger social networks and more chances to meet partners; agreeable people navigate conflict and connection more smoothly. The Extraversion effect was especially pronounced for men.
The three traits that ease partnership — Conscientiousness, Extraversion, and Agreeableness — are also the ones most tied to social reliability and warmth.
Neuroticism — a mixed, gender-split signal
For men, higher Neuroticism was linked to greater odds of being single; for women, that same link did not appear. The authors note substantial individual differences, so this is a tendency rather than a rule.
Neuroticism’s link to singlehood showed up for men but not women — a reminder that gender shapes how traits play out in dating.
What a 77,000-person study of lifelong singles found
Complementing the 2026 findings, a 2024 study in Psychological Science led by Julia Stern examined more than 77,000 Europeans aged 50 and older. Lifelong singles scored lower on Extraversion, Conscientiousness, and Openness than people who had been in relationships, and they reported somewhat lower life satisfaction. The team could not prove cause and effect, but they leaned toward personality as a cause rather than a consequence: relationships tend to change personality only briefly (for example, a new partner may temporarily draw an extravert inward, but the underlying trait recovers).
Across tens of thousands of people, the same three traits — Extraversion, Conscientiousness, and Openness — repeatedly separated those who couple from those who stay single.
Why personality shapes relationship status
Personality influences three phases of partnership identified in the research literature: attraction, formation, and maintenance. At attraction, traits affect how others perceive you and what you prioritize in a partner. At formation, they shape social skills, opportunities to meet people, and willingness to commit. At maintenance, they govern how you handle conflict and respond to a partner’s needs. Extraversion offers a concrete example: during the COVID-19 pandemic, a 2023 study by Chopik and colleagues found extraverted people were 10% to 26% more likely to form a new intimate relationship — likely because they kept more social channels open when others withdrew.
Personality works on relationships through three doors: who you attract, whether you form a bond, and whether it lasts.
Does this mean your personality decides your fate?
No. These are population-level tendencies with modest effect sizes, not personal verdicts. Many highly open, highly neurotic, or intensely independent people build lasting partnerships, and many conscientious extraverts stay single by choice or circumstance. The studies also cannot establish direction cleanly: it is plausible that being single nudges personality somewhat, even if the stronger arrow points the other way. Cultural context matters too — in societies where singlehood is more accepted, the same traits may matter less.
A personality profile raises or lowers the odds of being single; it does not determine the outcome.
What you can actually do with this
Knowing your standing on the Big Five is less about predicting your status and more about understanding your relationship patterns. If you score low on Extraversion, you might deliberately build structured ways to meet people; if you are high in Neuroticism, you might work on emotion regulation that supports steadier connections. Tools like personalitree.com offer free Big Five and 16-type assessments that take about ten minutes and give you a clear map of your traits. The point is not to “fix” your personality but to play to its strengths.
Self-awareness about your traits turns a static label into a practical advantage in how you connect with others.
Frequently Asked Questions
Can a personality test predict whether I’ll be single?
Not precisely. Research links certain Big Five traits to somewhat higher or lower odds of being single, but the effects are modest and shaped by context, gender, and personal choice. A test describes tendencies, not destiny.
Which personality type is most likely to stay single?
At the trait level, higher Openness shows the most consistent link to being single, especially for women, while higher Conscientiousness, Extraversion, and Agreeableness trend toward partnership. No single 16-personality-type label predicts this on its own.
Does being single change your personality?
Studies suggest the effect is small and temporary. The 2024 cross-cultural study found evidence that personality more often precedes singlehood than results from it — for instance, an extravert in a new relationship may turn inward briefly, then revert to baseline.
Are highly open people really less likely to couple up?
“Less likely” is accurate as a tendency, not a rule. Higher Openness was associated with greater odds of being single in the 2026 study, possibly because open people favor autonomy and unconventional lives, but many open people are in happy relationships.
How can I learn my own Big Five profile?
You can take a validated assessment online. Websites like personalitree.com make personality testing accessible, offering both Big Five and 16-personality-type frameworks so you can see where you land and how it might shape your relationships.
