Avoidance is the most natural human response to discomfort. If a situation feels threatening, our instinct is to escape or avoid it. However, in the context of anxiety disorders, avoidance is the primary mechanism that prevents recovery. Research by Mowrer (1960) and Barlow (2002) demonstrates that while avoidance provides immediate relief, it "locks in" the fear response for the long term.
This process interacts closely with the anxiety cycle, safety behaviours, and learned patterns.
When you avoid a feared situation (like a social event or a difficult conversation), your anxiety levels drop instantly. In psychology, this is called negative reinforcement. Your brain learns a dangerous lesson: "The only reason I am safe is because I ran away."
Because the brain never stays in the situation long enough to learn that it is actually safe, the original fear remains unchallenged. Over time, your world becomes smaller as you avoid more and more triggers.
Peer-reviewed research consistently points to Mowrer’s Two-Factor Theory to explain why anxiety persists:
Avoidance isn't always as obvious as staying home. Research by Salkovskis (1991) highlights "Safety Behaviours"—subtle ways we avoid the full experience of anxiety while still being present. These act as a "psychological crutch."
Examples of subtle avoidance include:
These behaviours maintain anxiety because they prevent Inhibitory Learning—the process of the brain learning that it can handle the distress.
According to Borkovec et al. (1994), even "worrying" is a form of avoidance. By constantly thinking about future threats, the mind avoids the physical sensations of anxiety and the emotional processing of the present moment. This "cognitive avoidance" keeps the threat system in a state of high alert.
To overcome anxiety, we must move from Avoidance to Approach. CBH facilitates this by lowering the physiological barrier to entry, making exposure feel manageable.
This approach is most effective when integrated with threat system retraining and challenging thinking errors.
