New research published in Psychology of aesthetics, creativity and art We found that people’s moral values shape how they judge paintings of nude bodies.
Nudity occupies an uneasy place in art. Nudity can be seen as beautiful, sacred, heroic, and liberating, but it can also be judged as shameful, obscene, or morally questionable. Researchers Kim N. Awa and colleagues frame this tension through a philosophical debate about whether aesthetic and moral values coexist. Some traditions associate beauty with goodness, while others argue that art can have aesthetic value even when it challenges moral comfort or social convention. This makes nude works a useful case study for asking why some viewers approach such images with curiosity or appreciation, while others react with discomfort or disapproval.
Researchers considered this issue through Moral Foundations Theory, which proposes that people differ in the moral values they prioritize. Personalizing moral foundations such as consideration and fairness emphasizes autonomy, prevention of harm, and protection of the individual. Binding moral foundations such as loyalty, authority, and purity emphasize standards of social order, tradition, group cohesion, and civility.
Because nude artwork can be interpreted either as artistic expression or as a violation of social norms, the authors expected that individuating morality would predict more favorable reactions to art, and constraining morality would predict more negative reactions.
This project included two studies using separate undergraduate samples recruited from a large public university in the southeastern United States. Both studies included 124 participants who rated paintings of nude or exposed women or exposed men, respectively. Participants completed learning remotely in exchange for course credit.
Paintings from the 16th to 20th centuries were obtained from publicly available art collections, including museum sources such as the Smithsonian Institution and the Metropolitan Museum of Art, and other public searches that allow tracing the provenance of artworks. To keep the visual content relatively consistent, the researchers selected paintings that featured a single nude or exposed figure in the center, with no other clearly visible figures around them. The people were posed sitting, lying, or standing, and the researchers attempted to standardize characteristics such as body size and skin color to reduce the likelihood that responses would reflect differences in perceived attractiveness unrelated to the nudity itself.
Participants rated each picture on how beautiful, funny, pornographic it was, and how disgusting they found it. These ratings used a scale from “not at all (adjective)” to “very much (adjective).” Participants also answered an open-ended question for each image: “How does looking at this picture make you feel?”
The authors analyzed these responses using linguistic probing and word counts 22 to generate an emotional tone score. Higher scores reflect a more positive emotional tone. After evaluating the paintings, participants completed a 30-item Moral Fundamentals Questionnaire, rating consideration, fairness, in-group loyalty, respect for authority, and purity on a six-point scale. The authors then created a more broadly personalized and binding Moral Foundations score from these subscales.
Study 1, which focused on paintings of nude women, found that people who endorsed more individualized moral foundations rated the artwork as more beautiful and more interesting. In contrast, people who supported more binding moral foundations rated the artwork as less beautiful, felt more discomfort while viewing it, and judged it to be more pornographic.
The broader pattern suggests that viewers who prioritize autonomy, consideration, and fairness are more likely to engage positively with nude artworks, whereas viewers who prioritize social order, tradition, and community norms are more likely to react with anxiety and moral disapproval. Additionally, paintings rated as more beautiful were generally rated as more interesting and emotionally positive, while higher levels of discomfort were associated with the artwork being viewed as more pornographic.
Study 2, which focused on pictures of naked men, yielded a largely similar pattern. Higher support for personalizing moral foundations again predicted viewing works of art as more beautiful and interesting. Higher support for binding moral foundations predicted that people would view the work as more pornographic, find it more offensive, judge it less beautiful, and be less interested in viewing it. When the authors examined the five moral foundations individually, care predicted more positive evaluations of male nude works, while ingroup loyalty and purity were associated with judging male nude works as more pornographic.
Across both studies, the results supported the authors’ central argument that moral values help shape aesthetic responses to nude art, even when the images are presented as art objects rather than explicitly sexual material.
This study further shows that reactions to nude artworks are shaped not only by those about the works themselves, but also by the moral priorities of the viewers, which may help explain widespread disagreements about art, censorship, education, and public display.
Notably, although many historical works of art depict nudity in scenes of collective, religious, or social significance, these paintings depict solitary naked male or female figures.
The study, “Personalization and Constraint of Moral Values as a Function of Evaluation of Artworks Depicting Nudity,” was authored by Kim N. Awa, Mitch Brown, and Darya L. Zavelina.
