Poles
Each HES element is a spectrum, not a category: the Low and High poles describe how it presents at its two extremes, while the Reference marks the typical, everyday middle. The poles map variation across the range — neither end is inherently better or worse.
Avoids effort quickly: discomfort triggers switching to easier/pleasurable options and rationalized delay.
High tolerance: can sustain hard effort without repeated internal “breaks,” excuse-making, or flight.
Can tolerate effort mainly with strong external structure or unusually high personal meaning.
Measure
• Duration: how long effort is sustained under persistent discomfort.
