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.
Negative outcome expectation bias: defaults to expecting failure; effort feels low-yield; frequent “probably won’t work.”
Positive outcome expectation bias: defaults to expecting success; effort feels worthwhile; frequent “likely to work.”
Balanced expectations: “it may work if...” with realistic constraint awareness.
Measure
Measuring Methods
• Tracking past forecasts vs. outcomes.
• “Reasonable effort” scenarios: expected success probability.
Empirical Anchor
Notes
• Risks at MIN: withdrawal, learned helplessness patterns.
• Risks at MAX: risk underweighting, resource overestimation.
