Revisiting the Disgust–Conservatism Link: A Meta-Analysis of Unpublished Evidence
This meta-analysis of over 3,200 participants from 14 unpublished datasets reveals that while disgust shows a small positive association with social conservatism (specifically regarding contamination), it lacks a reliable link to overall or economic conservatism, suggesting its practical impact on political attitudes is limited.

For decades, psychologists have wondered if a basic human emotion could help explain why people hold certain political views. Specifically, they have looked at disgust, that sharp, physical reaction we feel when we encounter something rotten, contaminated, or morally repulsive. The theory suggests that this feeling, which evolved to keep us away from disease and danger, might also shape how we view the world. Some researchers proposed that people who feel disgust more easily are also more likely to support conservative political ideas, perhaps because those ideas emphasize tradition, order, and protection against outside threats. This connection has been studied for years, with many published papers claiming to find a link between a person's sensitivity to disgust and their political stance. However, in science, there is a well-known problem where studies with no interesting results often sit unpublished in a researcher's file drawer, while only the studies finding a connection get printed in journals. This can make a weak link look much stronger than it really is.
To get a clearer picture, a researcher at Stetson University decided to look at the data that had never been published. Instead of relying on the studies that made the news, they gathered over 70 correlations from 14 different sets of data, involving more than 3,200 people. These datasets came from various sources, including college student pools and online participants, and they measured disgust in several ways, such as asking people how much they disliked things like vomit or dirty toilets, or how they reacted to pictures of disgusted faces. The researcher then combined all this unpublished information to see if the pattern held up when the file drawer was finally opened.
The results were surprisingly quiet. When looking at the big picture, the study found no reliable connection between a general feeling of disgust and a person's overall political conservatism or their views on economic issues like taxes and government spending. The data did not support the idea that feeling disgusted makes someone a conservative across the board. However, a small, specific pattern did emerge. There was a slight link between disgust and social conservatism, which covers views on issues like immigration, abortion, and gender rights. This connection was strongest when people were asked about their fear of contamination, such as touching a dirty surface or being near germs. Even then, the link was very weak. If you knew someone was highly sensitive to disgust, it would not help you guess their political views with much accuracy; the feeling would explain only a tiny fraction of their political stance.
The study also examined whether the way disgust was measured changed the results. It turned out that the connection to social conservatism was mostly driven by questions about physical contamination. Other types of disgust, such as reactions to sexual behavior or moral wrongs, did not show a consistent relationship with political views. When the researcher removed a few specific measurements that might have been confusing the results, the link to social conservatism became even smaller, though it remained statistically present. The findings suggest that while there is a real, tiny relationship between the fear of germs and social conservatism, it is not a powerful driver of political identity.
This does not mean disgust plays no role in politics, but it does suggest that its influence is far more limited than previously thought. The researcher notes that even a small bias could potentially grow over time through complex social cycles, but the direct evidence from these thousands of participants shows that disgust is just one small piece of a much larger puzzle. The study concludes that while the link exists, it is too weak to be the main reason people choose their political sides. For those trying to understand why people support certain policies or leaders, focusing solely on their sensitivity to disgust would likely lead to a very incomplete picture. The real story of political belief remains complex, involving many factors beyond a simple reaction to something gross.
