Leadership Traits: Big Five, Extraversion, Intelligence, Charisma, and Effectiveness

Leadership traits are relatively enduring individual differences—such as broad personality dimensions, cognitive ability, or narrower dispositional tendencies—that can help predict who is seen as a leader and, to a lesser extent, how effectively someone performs in a leadership role. The strongest conclusion from modern research is not that leaders possess one fixed profile. It is that traits contribute probabilistically, through behavior and perception, within specific situations. A foundational meta-analysis found that the Big Five jointly related meaningfully to leadership, with extraversion showing the most consistent association among the five broad domains (Judge et al., 2002). More recent multinational and facet-level meta-analyses have made the picture more precise: the same trait can matter differently for leader emergence and leadership effectiveness, and narrower facets, culture, hierarchical level, and behavior can change the strength and even the practical meaning of the relationship (Javalagi et al., 2024; Baker et al., 2026).
This distinction is essential. A person can look leaderlike, speak first, gain influence, or be selected by a group without producing better decisions, stronger team performance, greater learning, or healthier follower outcomes. The psychology of leadership therefore separates leader emergence from leadership effectiveness, and it also separates stable traits from leadership behaviors, styles, theories, formal authority, status, and power.
Leadership Traits: The Evidence in Brief
The evidence supports six high-level conclusions.
• Extraversion is one of the most reliable broad personality correlates of leadership, especially leader emergence. It is not a requirement for effective leadership, and its advantage is partly behavioral: assertiveness, verbal participation, social visibility, and task-focused engagement can make someone more likely to be perceived as a leader.
• Conscientiousness, openness to experience, and emotional stability also show meaningful associations with leadership outcomes, while agreeableness is usually weaker at the broad-domain level. Their importance changes when the outcome, context, culture, and narrower facets are specified.
• General cognitive ability is positively associated with leadership. A major meta-analysis estimated a corrected intelligence–leadership correlation of about .21 before correcting for range restriction and .27 after that correction. This is useful predictive information, not a threshold that separates leaders from nonleaders.
• Charisma should not be treated as if it were simply another Big Five personality trait. In leadership research, charisma can refer to follower perceptions, ratings, a leadership construct, or specific symbolic and emotion-laden signaling behaviors. Perceived charisma and actual effectiveness overlap imperfectly.
• Traits and behavior are connected. Meta-analytic evidence indicates that leadership behavior often explains more variance in effectiveness criteria than traits alone, and newer work supports behavioral mediation pathways linking traits to leadership outcomes.
• Most trait evidence is correlational or predictive. It does not establish that changing a stable trait will cause better leadership. Experimental evidence is much rarer, though experiments on state extraversion show that acting more extraverted in a group can increase emergent-leadership ratings.
What Is a Leadership Trait?
A leadership trait is an individual-difference characteristic that is relatively stable across time and situations and is studied because it predicts some leadership criterion. Personality dimensions such as extraversion are traits. General cognitive ability is an ability rather than a personality trait, although it is commonly included in the broader leader-trait literature. Charisma is more complicated because different research traditions operationalize it as a perception, attribution, relationship, style-like construct, or set of communicative behaviors. The trait approach therefore concerns predictors of leadership; it is not a synonym for leadership styles or leadership theories.
Leadership Traits vs Leadership Behaviors, Styles, and Theories
Traits describe relatively enduring characteristics of the person. Behaviors describe what leaders do. A leadership style is a recurring pattern of behavior or influence, such as transformational, transactional, autocratic, democratic, servant, or laissez-faire leadership. A leadership theory is an explanatory framework that specifies relationships among leaders, followers, situations, behaviors, incentives, identity, tasks, or outcomes.
This is why a person can be highly extraverted without using a transformational style, highly conscientious without being democratic, or cognitively able without being effective. Modern evidence favors integrative models in which traits affect the probability of certain behaviors, behaviors interact with context, and followers interpret both through social-cognitive expectations. DeRue and colleagues’ meta-analysis found that traits and behaviors together explained at least 31% of variance across several leadership-effectiveness criteria, with behaviors tending to explain more variance than traits (DeRue et al., 2011).
Leader Emergence Is Not Leadership Effectiveness
Leader emergence concerns who becomes influential, is nominated, assumes responsibility, is perceived as leaderlike, or takes a leadership role in a group. Leadership effectiveness concerns how well leadership works once enacted. Depending on the study, effectiveness can mean supervisor or follower ratings, group performance, follower satisfaction, task performance, citizenship behavior, learning, or other outcomes.
The two constructs are correlated but not interchangeable. A 2025 interpersonal-process study showed a useful example: extraversion was more important for leadership emergence through task-focused behavior and impressions of assertiveness, whereas agreeableness and emotional stability were more important for effectiveness through member-focused or calm behavior and impressions of trustworthiness and calmness (Härtel et al., 2025). The 2026 facet-level meta-analysis likewise concluded that personality facets differ substantially in their relationships with emergence and effectiveness (Baker et al., 2026).

How the Trait Approach Changed
Early leadership research often searched for a stable set of personal qualities that distinguished leaders from nonleaders. The approach lost influence when findings appeared inconsistent across situations and when researchers recognized that leadership cannot be reduced to a checklist of personal attributes. Later work revived trait research with better personality taxonomies, stronger measurement, meta-analysis, multilevel designs, and explicit attention to situations. Zaccaro argued that contemporary trait perspectives should examine meaningful configurations of attributes and situational boundaries rather than isolated traits (Zaccaro, 2007).
A modern trait model therefore asks several different questions: Which individual differences predict emergence? Which predict effectiveness? Through what behaviors? Under what conditions? For which outcomes? According to whom? Judge, Piccolo, and Kosalka formalized this broader logic by distinguishing leader emergence, perceived effectiveness, and actual effectiveness and by emphasizing mediators and moderators rather than assuming a direct trait-to-performance pipeline (Judge et al., 2009).
The Big Five and Leadership
The Big Five—extraversion, conscientiousness, openness to experience, agreeableness, and neuroticism/emotional stability—provide a broad taxonomy for personality. In the classic 2002 meta-analysis of 222 correlations from 73 samples, overall correlations with leadership were approximately −.24 for neuroticism, .31 for extraversion, .24 for openness, .08 for agreeableness, and .28 for conscientiousness. The multiple correlation for the five traits considered together was .48 (Judge et al., 2002). Those values summarize a heterogeneous literature; they should not be read as fixed universal effects for every role or every criterion.
The 2024 meta-analysis by Javalagi, Newman, and Li used a large multinational database covering leader emergence (120 samples; N = 32,579) and effectiveness (116 samples; N = 42,487). It found that culture can moderate personality–leadership relations, that leader behavior helps mediate several Big Five effects, and that Honesty–Humility adds predictive validity beyond the Big Five for effectiveness (Javalagi et al., 2024). The 2026 meta-analysis by Baker and colleagues, based on 203 data sets, went a level deeper and showed substantial variation among narrower personality facets and across contexts such as hierarchical level and organization type (Baker et al., 2026).
Extraversion: the most consistent broad predictor
Extraversion includes tendencies toward sociability, assertiveness, activity, positive emotionality, and social engagement. At the broad-domain level it is the Big Five trait most consistently associated with leadership, particularly with emergence. That pattern makes psychological sense: people who speak more, participate earlier, communicate confidence, and occupy more social space are easier for groups to notice and categorize as leaderlike.
But the label “extraversion” can hide different mechanisms. In group-process research, assertive and task-focused behavior can contribute more directly to emergent-leadership impressions than sociability by itself. The distinction matters because an introverted person can display assertive, structured, visible behavior when the situation calls for it. An experiment with 601 participants found that experimentally increasing state extraversion increased peer-rated and self-rated emergent leadership, demonstrating a causal effect on emergence behavior rather than proving that stable extraversion causes long-term leadership effectiveness (Spark & O’Connor, 2021).
The practical implication is precise: extraversion is an advantage in many emergence settings, not a license to equate talkativeness with competence. Selection systems that reward visible assertiveness can overvalue people who look leaderlike while missing quieter candidates whose judgment, expertise, reliability, listening, or team coordination may matter more after the role is obtained.
Conscientiousness: reliability, organization, and goal pursuit
Conscientiousness concerns dependability, self-discipline, organization, persistence, and goal-directedness. It has a meaningful positive association with leadership in the classic Big Five literature. Its value is plausible in roles that require planning, monitoring, follow-through, and consistent execution.
More recent evidence strengthens the behavioral interpretation. Javalagi and colleagues found support for initiating structure as a mediator connecting conscientiousness with leader outcomes (Javalagi et al., 2024). This does not mean conscientious leaders are effective because a trait itself directly produces performance. The trait can increase the probability of behaviors—clarifying tasks, structuring work, monitoring progress—that are useful under some conditions.
Openness to experience: complexity, novelty, and cognitive flexibility
Openness to experience encompasses curiosity, imagination, receptiveness to novelty, intellectual engagement, and preference for complexity. Its positive association with leadership is smaller than a simple “visionary leader” stereotype suggests, but it is meaningful in aggregate research. Openness may matter especially when leaders must learn, integrate unfamiliar information, reframe problems, or navigate change.
The situational qualification is important. Novelty seeking or idea generation is not automatically effective when the task primarily rewards precision, stability, procedural compliance, or rapid execution of known routines. At the trait level, openness is a probability shift, not a general-purpose leadership advantage.
Emotional stability and neuroticism
Emotional stability is the low pole of neuroticism. It concerns lower tendencies toward anxiety, emotional volatility, insecurity, and stress reactivity. The classic meta-analysis found a negative association between neuroticism and leadership overall, which can equivalently be described as a positive association between emotional stability and leadership.
Process evidence helps explain why this may matter. Härtel and colleagues found that emotional stability was more relevant to effectiveness than emergence in their group-interaction design, with calm behavior and impressions of calmness contributing to the pathway (Härtel et al., 2025). A leader’s ability to remain behaviorally regulated under pressure can influence how followers interpret uncertainty and how effectively a group coordinates.
Agreeableness: cooperation without automatic leadership advantage
Agreeableness includes compassion, cooperativeness, trust, and interpersonal concern. Its broad association with leadership was weak in the 2002 meta-analysis, which is one reason generic lists of “good leader traits” can be misleading. A trait that supports relationships does not necessarily make someone more likely to take or be granted leadership.
Yet broader averages can conceal outcome differences. Recent work indicates that agreeableness can matter more for effectiveness than emergence and can operate through consideration, member-focused behavior, and trustworthiness. Javalagi and colleagues also found that agreeableness, along with extraversion, was a stronger predictor of effectiveness in more collectivistic cultural contexts (Javalagi et al., 2024).
Why Big Five facets matter
Broad personality domains combine narrower facets that can pull leadership predictions in different directions. The 2026 meta-analysis of 203 data sets concluded that facet–leadership relationships vary substantially for emergence and effectiveness and can differ by hierarchical level and organization type (Baker et al., 2026). This is a major reason to resist claims such as “extraverts are the best leaders” or “agreeable people cannot lead.” Broad traits are useful summaries; facet patterns can be more diagnostic of the behaviors that matter in a particular leadership environment.
Honesty–Humility Beyond the Big Five
The HEXACO model adds Honesty–Humility, a dimension involving sincerity, fairness, modesty, and lower willingness to exploit others for personal gain. Javalagi and colleagues reported that Honesty–Humility robustly predicted leader effectiveness beyond the Big Five in their meta-analytic extension (Javalagi et al., 2024). This finding is especially relevant when effectiveness includes relational trust, ethical conduct, or the responsible use of influence.
It also shows why leadership traits and power and personality are connected but distinct topics. Personality can shape how people seek, interpret, and use influence, while holding power changes the situation in which those traits are expressed.
Intelligence and Leadership
General cognitive ability is one of the better-established individual-difference predictors in the leadership literature. Judge, Colbert, and Ilies meta-analyzed 151 independent samples from 96 sources and estimated a corrected intelligence–leadership correlation of .21 before correcting for range restriction and .27 after correcting for range restriction (Judge et al., 2004). The association is meaningful and far from deterministic.
Intelligence can help leaders identify patterns, learn complex systems, integrate information, anticipate consequences, and formulate solutions. It does not automatically create judgment, ethical restraint, social trust, domain expertise, courage, clear communication, or the behaviors needed to coordinate a team. A cognitively able person can fail as a leader, and a person with ordinary cognitive ability can lead effectively in a role that fits their expertise, relationships, and behavioral strengths.
This is also where leadership and management overlap without becoming identical. Complex managerial roles often demand planning, analysis, coordination, and decision-making, while leadership additionally concerns influence, direction, identity, and follower processes. The distinction is developed in Leadership vs Management: Psychology, Influence, Authority, and Decision-Making.
Charisma: Trait, Perception, or Behavior?
Charisma is one of the most frequently misunderstood terms in discussions of leadership traits. In everyday language it often means personal magnetism. In research, charisma has been operationalized in several ways, including follower ratings, charismatic leadership scales, attribution processes, and specific symbolic, value-based, and emotion-laden communication behaviors. A dedicated review of charismatic leadership is therefore needed to separate Max Weber’s historical concept, House’s leadership theory, later transformational traditions, and contemporary signaling approaches.
Perceived charisma is not the same as actual effectiveness
People carry implicit leadership theories—cognitive prototypes of what leaders are supposed to look and act like. Classic work identified charisma and intelligence among dimensions people use in their implicit concepts of leadership (Offermann et al., 1994), and a later Annual Review synthesized how implicit leadership and followership theories shape categorization, evaluation, and information processing (Lord et al., 2020). A leader who matches a prototype can therefore receive stronger leadership ratings even before objective performance is known.
This creates a measurement problem. If the same followers rate both a leader’s charisma and that leader’s effectiveness, common-method variance and halo effects can inflate their relationship. An early meta-analysis found that charisma–effectiveness relationships were substantially weaker when effectiveness was measured at the individual level and common-method variance was controlled; group-level performance relationships were stronger than individual-level performance relationships in the available studies (DeGroot et al., 2000).
A later meta-analysis of 76 independent studies and 36,031 individuals examined antecedents and more objective outcomes of charismatic leadership. It found that Big Five traits and cognitive ability differed in their associations with charisma dimensions and that charisma dimensions predicted outcomes such as supervisor-rated task performance, citizenship behavior, and group or organizational performance, while also emphasizing major conceptual and measurement limitations (Banks et al., 2017).
Charisma signaling and intelligence
Recent work treats charisma more explicitly as a set of communicative signals. Akstinaite and colleagues tested charisma signaling in an incentivized laboratory sample of 1,998 adults, a field sample of 134 public-service leaders, and a historical sample of 41 U.S. presidents. Intelligence correlated with charisma signaling across the studies; in the first two studies, Big Five or Big Six personality dimensions did not independently predict the charisma-signaling measure (Akstinaite et al., 2024). The authors describe these findings as evidence consistent with charisma as a costly signal, while also noting that the intelligence–charisma relationship itself is correlational.
This is another reason not to collapse charisma into extraversion. An extravert can be highly visible without producing sophisticated charismatic signals, and an intelligent communicator can produce compelling symbolic messages without being broadly extraverted. For the social influence side of charisma, see Referent Power: Identification, Admiration, Charisma, and Influence and Why Do People Follow Leaders? Charisma, Authority, Social Identity, and Followership.
Traits Predict Leadership Through Behavior
Traits matter partly because they alter the probability of behavior. The DeRue meta-analysis integrated traits and behaviors and found that behavior generally explained more variance in effectiveness criteria than traits alone (DeRue et al., 2011). Javalagi and colleagues later found meta-analytic support for specific mediation pathways: consideration mediated effects associated with extraversion and agreeableness, while initiating structure mediated effects associated with conscientiousness, extraversion, and openness (Javalagi et al., 2024).
This is a stronger model than the folk idea that a trait directly “makes” someone a leader. A trait can influence what a person notices, how quickly they act, how they communicate, how others interpret them, and what role they are offered. Those behaviors then interact with the task, followers, organizational rules, incentives, and history of the group.
Context Changes the Meaning of a Trait
There is no context-free ranking of leadership traits. A trait that helps in one leadership problem can create costs in another. High extraversion can aid emergence and communication but may also produce overtalking or insufficient listening in tasks that demand distributed expertise. High openness can help in innovation but become less useful when rapid procedural execution is paramount. High conscientiousness can support reliability yet become rigid if translated into micromanagement. Agreeableness can support trust while making conflict or unpopular decisions harder in some roles.
Culture is one documented moderator. In the multinational meta-analysis, Big Five traits—and extraversion and agreeableness in particular—were more strongly related to effectiveness in more collectivistic societies (Javalagi et al., 2024). Hierarchical level and organization type also moderated some facet-level relationships in the 2026 synthesis (Baker et al., 2026).
Task structure, environmental uncertainty, follower expertise, team interdependence, formal authority, and organizational incentives can all determine whether a trait becomes useful behavior, irrelevant background, or a liability. This is why trait evidence should be interpreted alongside leadership theories that explicitly model situation, task, and follower conditions.
Leadership Traits, Power, Authority, Status, Dominance, and Prestige
Leadership is not identical to power, authority, or status. Power is the capacity to affect outcomes or others’ options. Authority is socially or institutionally legitimate power. Status is socially conferred rank or esteem. Dominance obtains influence through force, threat, intimidation, or control; prestige obtains status through valued skill, knowledge, or freely conferred respect. The English Hub’s canonical bridge for this neighboring intent is Power and Leadership: Influence, Status, Authority, and Followership.
Traits can affect these routes without defining them. Assertiveness may aid emergence; aggressiveness can sometimes be mistaken for leadership; expertise can support prestige; narcissistic traits can increase early visibility. But a person’s route to rank is a social process, not a personality score. For the hierarchy distinction, see Dominance vs Prestige: Two Routes to Status, Influence, and Leadership, Power vs Status: Social Power, Prestige, Dominance, and Hierarchy, and Social Hierarchy: Power, Status, Dominance, Prestige, and Rank.
Narcissism, Confidence, and Other 'Leaderlike' Traits
Some characteristics can increase leaderlike impressions without improving effectiveness. Narcissism is a clear example. A meta-analysis found that narcissism was positively related to leader emergence but showed no linear relationship with leadership effectiveness; the emergence relationship was explained by extraversion, and self-rated effectiveness was more favorable than observer-rated effectiveness (Grijalva et al., 2015). This literature studies narcissistic traits as dimensional individual differences. It does not justify diagnosing Narcissistic Personality Disorder from workplace behavior or leadership style.
Confidence deserves similar caution. Confidence can support decisive behavior and clear communication, but perceived confidence is not evidence of calibration, expertise, or correct judgment. The psychology of leader emergence is full of cues that can affect who is followed before groups have enough outcome data to know who is effective.
Leadership Traits vs Leadership Selection
Personality and cognitive-ability measures can contribute useful information to leadership selection or development, but a validated predictor is not a stand-alone hiring rule. Selection validity depends on the criterion being predicted, the quality of the instrument, the job analysis, reliability, incremental validity over other predictors, fairness, legal context, and how scores are combined with work samples, structured interviews, past performance, and domain expertise.
A broad Big Five score cannot tell an organization whether a person will make sound decisions in a specific technical domain, handle a crisis ethically, build psychological safety, or lead a particular team. Likewise, an intelligence score does not measure leadership behavior, motives, values, integrity, experience, or organizational knowledge.
Popular personality typologies should not be upgraded into leadership diagnostics merely because their labels feel intuitive. The strongest evidence discussed here comes from dimensional trait models, cognitive-ability research, validated leadership measures, and meta-analytic synthesis.
Can Introverts Be Good Leaders?
Yes. The evidence that extraversion predicts emergence does not imply that introverts cannot lead effectively. Extraversion increases the probability of behaviors and impressions that help people become visible as leaders, especially in unstructured groups. It is neither necessary nor sufficient for effectiveness. Experimental evidence also shows that people can temporarily act more extraverted and receive higher emergence ratings (Spark & O’Connor, 2021).
An introverted leader can be highly effective through expertise, preparation, careful listening, calmness, clear structure, one-to-one influence, strong judgment, or deliberate communication. A more useful question than “Are introverts good leaders?” is “Which behaviors does this role require, and can this person reliably enact them under the conditions of the job?”
Are Leadership Traits Born or Developed?
Personality and cognitive ability have biological and developmental components, but leadership is a developmental outcome. Traits are not immutable instructions. People learn skills, change habits, gain expertise, enter new environments, receive feedback, and adopt behaviors that alter how their dispositions are expressed. The evidence on heritability, experience, training, and development is covered in Are Leaders Born or Made? Genetics, Personality, Training, and Leadership Development.
The distinction between trait change and behavior change is practical. A development program does not need to transform an introvert into an extravert to improve visible communication. It does not need to change a leader’s entire personality to teach clearer goal setting, better listening, structured decision procedures, conflict management, or charismatic communication tactics.
What Leadership-Trait Research Can and Cannot Establish
Meta-analysis strengthens estimates by synthesizing many studies, but it does not turn correlational data into randomized causal evidence. Much of the leadership-trait literature uses observational designs, personality self-reports, follower or supervisor ratings, and criterion measures that differ substantially across studies. Range restriction can reduce observed correlations when organizations have already selected relatively similar leaders. Common-source measurement can inflate relationships when the same respondent rates both the predictor-like leadership construct and the outcome.
Hoffman and colleagues’ quantitative review of individual differences and leader effectiveness emphasized that different individual differences relate differently to different effectiveness criteria (Hoffman et al., 2011). Reviews of the trait paradigm similarly distinguish actual and perceived effectiveness and stress mediators and contextual moderators (Judge et al., 2009).
Causal claims therefore require stronger designs: experiments that manipulate behavior, longitudinal studies that establish temporal ordering, natural experiments, or other designs that reduce confounding. Even then, changing a behavioral state is different from changing a stable trait.
A Practical Evidence-Based Framework
For organizations or individuals trying to use leadership-trait evidence responsibly, start with the outcome rather than the stereotype. First specify whether the goal is emergence, promotion readiness, team performance, follower experience, strategic judgment, safety, innovation, or another criterion. Then identify behaviors the role actually requires. Use validated individual-difference measures only when they add information relevant to that criterion. Finally, combine trait data with behavior, expertise, track record, structured observation, and context. This is consistent with the wider evidence summarized in What Makes a Good Leader? Personality, Emotional Intelligence, Trust, and Effectiveness.
For an individual leader, trait results are best treated as a map of likely tendencies. A high score does not guarantee a strength will be expressed effectively; a low score does not prove a behavior is unavailable. The development target is usually the behavior, judgment process, skill, or environmental fit that connects the disposition to the actual work.
Frequently Asked Questions
What are the most important leadership traits?
No single trait is most important across all leadership outcomes. Among the Big Five, extraversion is the most consistent broad predictor in classic meta-analysis, especially for emergence, while conscientiousness, openness, and emotional stability also matter. More recent evidence shows that narrower facets, culture, hierarchy, and the emergence/effectiveness distinction substantially refine these averages (Judge et al., 2002; Baker et al., 2026).
Is extraversion the strongest leadership trait?
At the broad Big Five level, extraversion has shown the most consistent overall association with leadership. Its advantage is especially clear for leader emergence. That does not make it the strongest predictor of every effectiveness criterion or every leadership role.
Does intelligence make someone a better leader?
Intelligence is positively associated with leadership, with a major meta-analysis estimating corrected correlations around .21 to .27 depending on range-restriction correction (Judge et al., 2004). It contributes useful predictive information but does not determine leadership effectiveness by itself.
Is charisma a personality trait?
Not in the same straightforward sense as a Big Five dimension. Leadership research has treated charisma as a follower attribution, leadership construct, perception, and increasingly as a set of value-based, symbolic, emotion-laden signaling behaviors. The meaning depends on the measure and theory being used.
Does charisma prove a leader is effective?
No. Charisma can predict some objective or independently rated outcomes, but perceived charisma can also be affected by halo effects and leader prototypes. Meta-analytic findings become weaker under some measurement conditions, which is why charisma ratings should not be treated as equivalent to objective effectiveness (DeGroot et al., 2000; Banks et al., 2017).
Can leadership traits be trained?
Stable traits are not the same thing as trainable leadership behaviors. Development can improve communication, goal setting, listening, feedback, decision procedures, and other behaviors without requiring wholesale personality change. Trait expression can also change with roles and situations.
Do personality tests predict leadership?
Validated dimensional personality measures can contribute predictive information, but validity depends on the leadership criterion, instrument, population, context, and selection system. A personality score should not be treated as a diagnosis, a deterministic forecast, or a complete measure of leadership potential.
What is the difference between leadership traits and leadership styles?
Traits are relatively enduring individual differences; styles are recurring patterns of leader behavior or influence. Extraversion is a trait. Transformational, transactional, servant, autocratic, democratic, and laissez-faire leadership are style or behavior constructs. See Leadership Styles: Lewin, Goleman, Transformational, Servant, and Situational Leadership for the dedicated taxonomy.
Why can someone emerge as a leader but still be ineffective?
Emergence depends partly on visibility, assertiveness, confidence, prototypes, status signals, and group processes. Effectiveness depends on what happens after influence is gained: judgment, coordination, task structure, relationships, expertise, ethics, context, and outcomes. The predictors overlap only partly, which is why the two constructs must be analyzed separately.
