Is Disgust the Silent Driver of Anxiety? How Our Brains Misinterpret Threats
"New research sheds light on the surprising role of disgust in anxiety disorders and how this 'disgust bias' impacts our mental well-being."
For years, fear has been the primary focus in understanding anxiety disorders. However, recent research highlights the significant role that disgust plays in the development and maintenance of these conditions. While theoretical and empirical research on disgust has been limited, the past decade has seen a surge in studies implicating disgust in disorders like obsessive-compulsive disorder (OCD), blood-injection-injury (BII) phobia, and spider phobia.
Disgust is a basic emotion recognized across cultures, producing unique facial expressions and subjective experiences like revulsion and nausea. Initially viewed as a food rejection mechanism to avoid contamination, disgust is now understood as a broader protective response against all sources of contaminants.
While disgust's role in anxiety disorders is increasingly recognized, it remains unclear whether disgust directly causes or merely exacerbates anxiety. Some argue it's a secondary phenomenon to heightened fear, while others suggest it induces a negative interpretational bias, indirectly contributing to anxious psychopathology.
The 'Disgust Bias': How Disgust Warps Our Perception of Threats

A study published in the Journal of Experimental Psychopathology explored whether induced disgust facilitates an interpretational bias and whether factors related to anxiety and disgust sensitivity moderate this bias. Participants were assigned to one of three groups: neutral, anxiety, or disgust mood induction. They then completed a homophone spelling task to assess their interpretational biases.
- Anxiety and Threat Perception: Experiencing anxiety can significantly alter how we perceive neutral situations, making us more likely to see them as threatening.
- Disgust's Influence: Similarly, induced disgust can also lead to a heightened sense of threat, showcasing its potential impact on our interpretation of the world around us.
- Homophone Test Insights: Using homophone spelling tasks helps reveal these hidden biases, providing a method to measure how emotions like anxiety and disgust can warp our perceptions.
Practical Implications: Managing Disgust and Anxiety in Everyday Life
While the study didn't find moderators for the disgust bias, understanding the connection between disgust and anxiety can still provide valuable insights. Here are some practical approaches:
