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.
Effort fragility: drive and willingness to continue drop rapidly; frequent stopping, postponing, task-hopping, and early quitting at the first friction point. External pressure, oversight, or hard deadlines are often required to sustain engagement.
Effort can be carried for long stretches despite slow feedback. The person can push through boredom, resistance, uncertainty, and fatigue while keeping direction and tempo.
Sustains effort well in familiar work, but long, ambiguous, or aversive phases require structure, breaks, support, or deliberate task chunking.
Measure
Measuring Methods
• Compare time-to-break under matched difficulty and controlled conditions (sleep, load, distractions).
Empirical Anchor
Notes
• Risks at MIN: chronic non-completion, dependence on external pressure, erosion of self-efficacy.
• Differs from C001Attentional Stability (one may hold focus but fail to sustain effort, and vice versa).
• Differs from C016Task Completion Tendency (process endurance vs. closure tendency).
