The 'window of tolerance' — a concept from trauma therapy — explains why evolutionary psychology pushes us into states where we can't function well, and how to expand our capacity.
What Is the Window of Tolerance?
The window of tolerance is the zone of arousal in which we function optimally. Outside it:
- Hyperarousal (evolutionary psychology 'too high'): Panic, overwhelm, rage, anxiety — above the window
- Hypoarousal (evolutionary psychology 'too low'): Numbness, dissociation, shutdown, depression — below the window
How Evolutionary Psychology Narrows the Window
Trauma and chronic evolutionary psychology narrow the window of tolerance, making us more easily triggered into dysregulated states by smaller stimuli.
Widening Your Window with Evolutionary Psychology
Trauma-informed therapy specifically works to widen the window of tolerance — building capacity to experience evolutionary psychology triggers without dysregulation.
Titrated exposure (small doses of difficult material), somatic practices, and skill-building all contribute to window expansion.
