Version v1.3.2

Definition

The ability and willingness to state one’s position clearly, defend boundaries, and push a decision through resistance, without requiring aggression.

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.

Low Pole

Non-assertiveness: struggles to state and hold a position under pressure; yields quickly or avoids confrontation.

High Pole

States and holds position easily; can conduct difficult conversations and insist when needed.

Reference

Present but context-dependent: varies with opponent status, fatigue, and issue importance.

Measure

Resistance threshold at which the person yields: how much pressure is required to make them back down.

Measuring Methods

• Negotiation role-plays with graded pushback.
• Behavioral markers: refusals, requests, saying “no,” boundary maintenance.
• Conflict observation: persistence without disintegration.

Empirical Anchor

Assertiveness (Alberti & Emmons, 1970); extraversion — assertiveness facet (Costa & McCrae, 1992); interpersonal agency.

Notes

• Not the same as aggression: assertiveness can be calm and respectful.
• Risks at MIN: chronic yielding, resentment accumulation.
• Risks at MAX: rigidity, reduced flexibility, social collisions.
