Higher Neuroticism Associated with Increased Frequency of Sexual Fantasies

In a groundbreaking study emerging from Michigan State University, researchers have unveiled compelling links between core aspects of personality and the frequency of sexual fantasies. Published in the renowned open-access journal PLOS One on February 4, 2026, this expansive study involving over 5,200 American adults marks one of the most detailed efforts to parse the intricate connections between the Big Five personality traits and the nuanced tapestries of human sexual imagination.

Sexual fantasies, often regarded as intimate and private, have long been recognized by psychologists as a significant component of human sexuality, contributing to personal well-being and relational dynamics. Despite their importance, the relationship between recurring fantasy themes and stable personality characteristics has remained largely unexplored at scale—until now. Emily Cannoot and colleagues have bridged this gap by statistically relating key personality domains to the frequency and thematic content of sexual fantasies, offering novel insights into how who we are influences how—and how often—we imagine.

The research hinged on two meticulously validated questionnaires administered to over 5,225 participants from various demographic backgrounds across the United States. The first instrument quantified not just the overall frequency of sexual fantasies but also cataloged them into four overarching thematic categories: exploratory, intimate, impersonal, and sadomasochistic. Exploratory fantasies included daring scenarios such as participating in group encounters, while intimate fantasies focused on romantic, emotional connection settings. Impersonal content covered voyeuristic interests, and sadomasochistic themes involved consensual elements of dominance and submission.

The second questionnaire measured participants’ standings on the Big Five personality traits, a psychological framework extensively validated for capturing broad dimensions of human personality: extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience. Uniquely, this study also delved into subcomponents or facets of these traits, allowing for a refined understanding of how specific elements of personality—for example, depressive tendencies within neuroticism or respectfulness within agreeableness—correlate with sexual fantasy patterns.

One of the study’s most striking findings concerns the role of neuroticism, a trait encompassing emotional instability and heightened sensitivity to stress. Participants exhibiting higher neuroticism scores, particularly those with pronounced depressive aspects, reported more frequent sexual fantasies across all categories. This correlation suggests a possible psychological mechanism whereby individuals with heightened emotional reactivity might engage more intensively in fantasy as a form of cognitive or emotional coping.

Contrastingly, traits representing conscientiousness and agreeableness showed inverse associations with sexual fantasy frequency. People who scored highly in these domains—characterized by responsibility, self-discipline, respectfulness, and kindness—tended to fantasize less often, regardless of fantasy type. These inverse correlations may reflect a greater adherence to social norms or a predisposition toward self-regulation which could temper the frequency or expression of imaginative sexual scenarios.

Intriguingly, the traits of extraversion and openness to experience did not demonstrate significant correlations with how often participants engaged in sexual fantasizing. This outcome runs counter to some expectations, especially regarding openness, which is often linked to creativity and novelty-seeking, characteristics seemingly aligned with fantasy generation. This dissociation hints that the link between personality and sexual fantasies might be subtler and mediated by specific facets rather than broad traits.

The granular investigation of facets offered further revelations. Facets representing responsibility and respectfulness within conscientiousness and agreeableness primarily drove the negative associations with fantasy frequency. Meanwhile, depressive facets within neuroticism were the key drivers of positive associations. These patterns underscore the importance of parsing personality dimensions beyond their superficial labels to understand their nuanced impact on sexual cognition.

This study’s methodology stands out for its robust sample size and comprehensive survey instruments, yet the authors acknowledge the need for expansion. Future research avenues could include culturally diverse samples to assess cross-cultural variability in the personality-fantasy nexus, as well as longitudinal designs to dissect how personality and sexual imagination co-evolve over time. Such extensions would deepen understanding of these intimate psychological processes.

Clinically, these findings bear important implications. Recognizing that individual traits predict aspects of sexual fantasy frequency and patterning could enhance psychotherapeutic approaches addressing sexual wellbeing, dysfunction, or distress. Therapists might tailor interventions with an awareness that personality profiles naturally shape fantasy life, normalizing diverse fantasy experiences and fostering healthier sexual self-concepts.

Cannoot and colleagues emphasize the predictive power of personality in sexual fantasy research lies in its incremental value—it neither fully explains nor replaces the complex mosaic of factors influencing sexual imagination. Nevertheless, establishing replicable, statistically meaningful links between personality traits and sexual fantasy patterns advances scientific understanding and opens new avenues for both research and applied psychological work.

From a broader psychological perspective, this research integrates the domains of personality psychology and human sexuality, creating a more holistic lens on human behavior. It challenges assumptions that sexual fantasies are purely situational or idiosyncratic by illuminating trait-based consistencies, thereby reinforcing the bidirectional interplay between enduring personality features and dynamic sexual processes.

In sum, this pioneering investigation offers a detailed, data-rich panorama of how the fundamental building blocks of personality shape a universal yet deeply individual aspect of human experience: sexual fantasy. Its findings encourage continued scientific exploration and provide clinicians with evidence-based knowledge to better support sexual health and happiness.
