The Five Dimensions of Leader Personality
These five factors emerged organically from leaders and followers' generated language — not from theoretical assumptions.
Energy
Charisma, excitement, enthusiasm, and activity level. Similar to extraversion trait
Psychopathy
The dark side of leadership — antisocial orientation, lacking empathy and remorse, corruption and disingenuousness.
Organization
Focuses on order, structure, performance-orientation, and accuracy. Similar to conscientiousness trait.
Irritability
Hot-tempered, aggressive behavior and volatility. The low end reflect calmness.
Intellect
Wisdom, rationality, and cognitive sharpness.

Why a Lexical Approach?
Most leadership research starts with theory — asking participants to rate leaders on pre-defined scales. The lexical approach goes the other way: it starts with natural language. By asking leaders to describe themself or followers to describe their leaders using varity of describtions, we capture the personality dimensions that actually matter to people, not just the ones researchers assumed would matter.
The Core Insight
If you want to know what personality dimensions matter in a leader, don't ask researchers — ask followers. The adjectives people naturally reach for when describing their leaders encode centuries of accumulated social knowledge about what leadership actually is.
Why Not the Big Five?
The Big Five personality framework (Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism) was derived from descriptions of people in general. But leaders are not 'people in general.' When followers describe their leaders, two factors emerge that the Big Five simply cannot capture:
Supportiveness — a warm, nurturing quality that followers cite as crucial but that Big Five measures as generic Agreeableness
Weakness — a factor describing ineffective, passive, or cowardly leaders, absent from all standard frameworks

Study Design
Study 2: Item Derivation
Hebrew-speaking followers generated free descriptions of leaders they had personally known. These descriptions were analyzed, reduced to a list of personality adjectives, and factor-analyzed to reveal the five-factor structure.
Study 4: Cross-Sector Validation
The factor structure was validated across three organizational contexts — Business, Military, and Religious — confirming both the universality of the five factors and meaningful sector-specific differences in factor scores.
The Five-Factor Model
Energy
Captures leadership presence: charisma, confidence, and daring. The single strongest predictor of perceived leadership effectiveness across all three sectors.
Psychopathy
The dark triad in leadership context. Items like "cruel," "abusive," and "sadistic" emerged organically from follower reports — absent from Big Five but central to the follower experience.
Organization
Methodical, accurate, performance-driven behavior. Reverse-coded items (childish, eccentric, infantile) define the low pole — critical for business and military contexts.
Irritability
Hot-tempered, aggressive, and confrontational behavior. Highest in military leaders, lowest in religious — context shapes acceptable expression.
Intellect
Rational, wise, cognitively sharp leadership. Universally prized — the only factor with a reverse-coded item (silly) and near-uniform benchmarks across sectors.
