How the Emotion of Disgust Influences Political Decisions

Understanding Disgust

• 💡 Disgust is a basic emotion that acts as a visceral gut reaction, prompting us to reject potential contaminants.
• 🧠 While disgust reactions are automatic, our response to them is not, allowing us to choose whether to let it drive our decisions.
• 🌍 Triggers for disgust are universal, but what specifically elicits the emotion is often culturally constructed and learned.

Evolutionary and Social Roles of Disgust

• 🛡️ From an evolutionary perspective, disgust is an adaptive physiological response that protects us from illness and disease, exemplified by conditioned taste aversion.
• 📜 Historically, disgust has driven social change, as seen with Upton Sinclair's novel "The Jungle," which led to significant food safety regulations.
• 🗣️ On a social level, emotions like disgust help us communicate feelings quickly and efficiently, reinforcing cultural norms and identities.

Disgust Sensitivity and Public Policy

• 📊 Research shows that individuals with higher disgust sensitivity are more likely to support policies perceived as protective of their bodies, souls, or society.
• ➡️ This sensitivity can influence views on public policies, including support for government spending on food safety systems.
• 🚫 Conversely, disgust-laden rhetoric can lead to intolerance and support for exclusionary policies targeting stigmatized groups.

Disgust, Disease, and Imagination

• 🦠 Before COVID-19, higher disgust sensitivity correlated with a desire for government protection against disease outbreaks like Zika and Ebola, including border closures, regardless of political affiliation.
• 💭 Disgust can be triggered by both real and imaginary contaminants, as illustrated by the law of similarity, where an object's objectionable qualities are imparted to something that merely resembles it.
• 🍽️ This reliance on imagination, as in conditioned taste aversion, can sometimes hold us back from beneficial experiences, such as exploring insects as a sustainable food source, despite two billion people worldwide relying on them.

Conclusion: Managing Disgust's Influence

• ⚖️ Disgust is a potent emotion that can lead to protection and even connection with political opponents, but it can also be misinformed by imagination and steer us in the wrong direction.
• ✅ We have the agency to decide whether disgust remains in the driver's seat of our decision-making or is relegated to the back seat, allowing other thoughts and emotions to guide us.
