Paradoxical intention is a logotherapy technique for anxiety-driven physical symptoms: instead of trying to suppress or avoid a feared reaction, the person is instructed to deliberately and exaggeratedly try to produce it. This works because anticipatory anxiety about a symptom (sweating, stammering, a muscle cramp) is often what actually triggers or worsens it — removing the fear by replacing it with a deliberate, almost absurd goal breaks the anxious feedback loop that was sustaining the symptom in the first place.
The technique's speed is part of what makes it clinically notable: because it targets the anxiety-symptom feedback loop directly rather than an underlying unconscious cause, resolution can happen within days rather than the months or years typically associated with working through anxiety in other ways.
