Researchers at the University of Toronto observed links between certain personality traits and the romantic situation of those surveyed. In their work, the researchers observed higher neuroticism scores among single people.

Introverted people, on the other hand, have a “greater ability to enjoy solitude," which "suggests a better ability to capitalize on alone time in a positive way,' the researchers argue. The study will be published in the journal Personality and Social Psychology Bulletin on February 7, 2024, in the form of an open-ended question. For the purposes of this study, 1,800 people aged 20 to 59, single or in a relationship for at least six months (for both cases), were interviewed. Each of them answered a questionnaire relating to their personality and their levels of satisfaction regarding their relationship status, their sexual fulfillment, and their overall position in life. The researchers used the "Big-5" model, which identifies five personality traits: openness (a desire for daily discovery), conscientiousness, extroversion, agreeableness, and neuroticism.
